Nature of Business and Basis of Presentation [Abstract] | |
Nature of Business and Basis of Presentation | Note 1 – Nature of Business and Basis of Presentation Nature of Business : the Nasdaq Capital Market Prior to July 2016, the Company was focused on developing the C-Pulse® Heart Assist System for treatment of Class III and ambulatory Class IV heart failure. In August 2016, the Company acquired the Aquadex FlexFlow business from a subsidiary of Baxter International, Inc. (“Baxter”), a global leader in the hospital products and dialysis markets (herein referred to as the “Aquadex Business”). On September 29, 2016, the Company announced a strategic refocus of its strategy that included halting all clinical evaluations of its C-Pulse technology to fully focus its resources on its recently acquired Aquadex Business. On May 23, 2017, the Company announced it was changing its name from Sunshine Heart, Inc. to CHF Solutions, Inc. to more appropriately reflect the direction of its business. During 2017, the Company’s board of directors and stockholders approved two reverse stock splits (together, the “Reverse Stock Splits”). Neither reverse stock split changed the par value of the Company’s common stock or the number of common or preferred shares authorized by the Company’s Fourth Amended and Restated Certificate of Incorporation. The first reverse stock split was a 1-for-30 reverse split of the Company’s outstanding common stock that became effective after trading on January 12, 2017. The second reverse stock split was a 1-for-20 reverse split of the Company’s outstanding common stock that became effective after trading on October 12, 2017. All share and per-share amounts have been retroactively adjusted to reflect the Reverse Stock Splits for all periods presented. Principles of Consolidation: For further information, refer to the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. Going Concern: The Company became a revenue generating company after acquiring the Aquadex Business in August 2016. The Company expects to incur additional losses in the near-term as it grows the Aquadex Business, including investments in expanding its sales and marketing capabilities, purchasing inventory, manufacturing components, and complying with the requirements related to being a U.S. public company. To become and remain profitable, the Company must succeed in expanding the adoption and market acceptance of Aquadex. This will require the Company to succeed in training personnel at hospitals and in effectively and efficiently manufacturing, marketing and distributing Aquadex and related components. There can be no assurance that the Company will succeed in these activities, and it may never generate revenues sufficient to achieve profitability. On July 3, 2018, April 24, 2017 and on November 27, 2017, the Company closed on underwritten public equity offerings for aggregate net proceeds of approximately $28.8 million after deducting the underwriting discounts and commissions and other costs associated with the offerings (see Note 4 - Equity). The Company will require additional funding to grow its Aquadex Business, which may not be available on terms favorable to the Company, or at all. The Company may receive those funds from the proceeds from future warrant exercises, issuances of equity securities, or other financing transactions. Should warrant exercises not materialize or future capital raising be unsuccessful, the Company may not be able to continue as a going concern. No adjustments have been made relating to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should the Company not continue as a going concern.

This guidance is effective for the Company’s annual and quarterly periods beginning January 1, 2019.

Revenue Recognition [Abstract] | |
Revenue Recognition | Note 2 – Revenue Recognition Net Sales The Company sells its products in the United States primarily through a direct sales force. Customers who purchase the Company’s products include hospitals and clinics throughout the United States. In countries outside the United States, the Company sells its products through a limited number of specialty healthcare distributors in the United Kingdom, Italy, Spain, Germany, and Southeast Asia. The majority of these distributors resell the Company’s products to hospitals and clinics in their respective geographies. Revenue from product sales are recognized when the customer or distributor obtains control of the product, which occurs at a point in time, most frequently upon shipment of the product or receipt of the product, depending on shipment terms. The Company’s standard shipping terms are FOB shipping point, unless the customer requests that control and title to the inventory transfer upon delivery. Revenue includes shipment and handling fees charged to customers. Revenue is measured as the amount of consideration the Company expects to receive, adjusted for any applicable estimates of variable consideration and other factors affecting the transaction price, which is based on the invoiced price, in exchange for transferring products. All revenue is recognized when the Company satisfies its performance obligations under the contract. The majority of the Company’s contracts have a single performance obligation and are short term in nature. The Company has entered into extended service plans with customers that are recognized over time. Revenue from extended service plans represents less than 1% of net sales for the both the three- and nine-month periods ended September 30, 2018. The unfulfilled performance obligations related to these extended service plans is included in deferred revenue in the amount of $41,250 and $38,000 as of September 30, 2018 and December 31, 2017, respectively. Deferred revenue is included in other current liabilities on the condensed consolidated balance sheets. The majority of the deferred revenue is expected to be recognized within one year. Sales taxes and value added taxes in foreign jurisdictions that are collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales. Revenue includes shipment and handling fees charged to customers. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of goods sold. Product Returns: believes that future returns of its products will be minimal. Therefore, revenue recognized is not currently impacted by variable consideration related to product returns. |

Debt [Abstract] | |
Debt | Note 3 – Debt On August 5, 2016, the Company entered into a loan and security agreement with Silicon Valley Bank (the “Bank”) for a $1.0 million revolving line of credit (the “Revolving Line”). Under the Revolving Line, the Company may borrow the lesser of $1.0 million or 80% of its eligible accounts (subject to customary exclusions), minus the outstanding principal balance of any advances under the Revolving Line. Advances under the Revolving Line, if any, accrue interest at a floating annual rate equal to 1.75% or 1.0% above the prime rate, depending on liquidity factors. The loan agreement contains customary representations, as well as customary affirmative and negative covenants. Outstanding borrowings, if any, are collateralized by all of the Company’s assets, excluding intellectual property which is subject to a negative pledge. Advances under the Revolving Line are subject to various conditions precedent, including compliance with financial covenants relating to net liquidity relative to monthly cash burn, which the Company may or may not meet depending on its cash position at any given point. The Revolving Line expires March 31, 2020. There were no borrowings outstanding under this facility as of September 30, 2018 or December 31, 2017. Warrants: |

Equity | Note 4 – Equity Series B/B-1 Convertible Preferred Stock Series C and D Convertible Preferred Stock . Series E Convertible Preferred Stock The Series E Convertible Preferred Stock included a beneficial conversion amount of $1.0 million, representing the intrinsic value of the shares at the time of issuance. This amount is reflected as an increase to the loss per share allocable to common stockholders in the nine months ended September 30, 2017 . Series F Convertible Preferred Stock The offering was comprised of Series F preferred stock, convertible into shares of the Company’s common stock at a conversion price of $4.50 per share. Each share of Series F preferred stock was accompanied by a Series 1 warrant, which expires on the first anniversary of its issuance, to purchase 223 shares of the Company’s common stock at an exercise price of $4.50 per share, and a Series 2 warrant, which expires on the seventh anniversary of its issuance, to purchase 223 shares of the Company’s common stock at an exercise price of $4.50 per share. The Series F preferred stock and the warrants were immediately separable and were issued separately . July 2018 Offering: underwritten public offering of 2,547,169 shares of its common stock at a public offering price of $2.12 per share, for gross proceeds of $5.4 million, prior to deducting underwriting discounts and commissions and offering expenses (the “July 2018 Offering”). In connection with the July 2018 Offering, and to induce certain institutional investors who hold warrants issued by the Company in November 2017 (“November 2017 Warrants”) to participate in the July 2018 Offering, the Company entered into letter agreements with such institutional investors (collectively, the “Warrant Reprice Agreements”). Pursuant to the terms of the Warrant Reprice Agreements, the Company agreed, effective July 3, 2018, to (a) reduce the per share exercise price of the November 2017 Warrants held by such institutional investors (the “Repriced Warrants”) to $2.12 and (b) extend the expiration date of the Repriced Warrants that were to expire on November 27, 2018 to November 27, 2019. The number of shares underlying the Repriced Warrants after the price reduction did not change. The Repriced Warrants are exercisable for 7,760,400 shares of common stock in the aggregate, of which, following such amendment, half expire on November 27, 2019 and half expire on November 27, 2024. The repricing of the warrants was accounted as an equity financing cost, with no impact to net proceeds from the offering. As noted above, the Company’s outstanding Series F preferred stock is subject to full-ratchet anti-dilution protection in the event the Company sells any common stock at a price lower than the then-conversion price of the Series F preferred stock. As a result of the July 2018 Offering, effective July 3, 2018, the conversion price of the Series F preferred stock was reduced from $4.50 to $2.12, the per share price to public in the July 2018 Offering. Placement Agent Fees Investor Warrants In connection with the issuance of the Series C and D Convertible Preferred Stock in November 2016, the Company issued the investor, at no additional cost, warrants to purchase 35,295 shares of common stock at an exercise price of $108 per share. In connection with the issuance of the Series D Convertible Preferred Stock at the second closing in January 2017, the Company issued the investor, at no additional cost, warrants to purchase 1,961 shares of common stock at an exercise price of $108 per share. The warrants were exercisable for 60 months commencing on the earlier of the day of the receipt of approval of the Company’s stockholders of a proposal to approve the issuance of the shares of common stock underlying the warrants, or the six-month anniversary of the date of issuance. These warrants were subject to a reduction of the exercise price if the Company subsequently issued common stock or equivalents at an effective price less than the current exercise price of such warrants. Warrant Exercise Agreement: The Company entered into the letter agreement with the investors to incent the exercise of the Original Warrants in order to receive the cash proceeds from the exercise of the Original Warrants and because the exercise of the Original Warrants would allow the Company to remove the warrant liability from its consolidated balance sheet and avoid future fair value adjustments and associated volatility in its consolidated financial statements, as the Replacement Warrants are not accounted for as liabilities based on their terms. As of September 30, 2018, and December 31, 2017, there were no Original Warrants outstanding and all Replacement Warrants under the letter agreement had been issued. Placement Agent Warrant: Warrant Valuation The Replacement Warrants were valued at $0.5 million using the Black Scholes valuation model with the following assumptions: an expected dividend yield of 0%, expected stock price volatility of 49.65%-50.38%, risk-free interest rates of 1.95%-1.97% and an expected life of 5 years. The warrants have a five-year life and were fully vested at the date of grant. The terms of these warrants do not require them to be accounted for as liabilities and are therefore recorded in equity. As in incentive to early exercise the Original Warrants, the fair value provided to investors through the Replacement Warrants exceeded the fair value of the Original Warrants that was relinquished by the warrant holders by approximately $0.1 million, which has been reflected as an expense in the statement of operations for the nine-month period ending September 30, 2017. |

Fair Value of Financial Instruments [Abstract] | |
Fair Value of Financial Instruments | Note 6 - Fair Value of Financial Instruments The Company’s financial instruments consist of cash and cash equivalents, warrants, and contingent consideration. Pursuant to the requirements of ASC Topic 820 Fair Value Measurement, · Level 1 · Level 2 · Level 3 The fair value of the Company’s common stock warrant liability related to the Original Warrants was calculated using a Monte Carlo valuation model and was classified as Level 3 in the fair value hierarchy. All Original Warrants were exercised during the nine months ended September 30, 2017. The fair value of the Company’s warrant liability related to the placement agent warrants was calculated using a Black Scholes valuation model and is classified as Level 3 in the fair value hierarchy. The following is a rollforward of the fair value of Level 3 warrants: Nine months ended September 30, 2017 (in thousands) Balance December 31, 2016 $ 1,843 Change in fair value (1,469 ) Exercise of warrants (368 ) Ending balance as of September 30, 2017 $ 6 Fair values were calculated using the following assumptions: As of Dec. 31, As of date of exercise Risk-free interest rates, adjusted for continuous compounding 1.47/1.96 % 1.45-1.99 % Term (years) 3.1/5.3 2.84-5.50 Expected volatility 55.3/49.8 % 49.9-58.5 % Dates and probability of future equity raises various various The fair value of the Company’s contingent consideration related to the acquisition of the Aquadex Business from Baxter in August 2016 (see Note 8 – Commitments and Contingencies), was $126,000 as of both September 30, 2018 and December 31, 2017. The fair value was initially measured based on the consideration expected to be transferred (probability-weighted), discounted back to present value, and it is considered a Level 3 instrument. The discount rate used was determined at the time of measurement in accordance with accepted valuation methods. The Company measures the liability on a recurring basis using Level 3 inputs including probabilities of payment and projected payment dates. Changes to any of the inputs may result in significantly higher or lower fair value measurements. There were no changes in the fair value of the contingent consideration subsequent to the initial measurement. All cash equivalents are considered Level 1 measurements for all periods presented. The Company does not have any financial instruments classified as Level 2 or any other classified as Level 3 and there were no movements between these categories during the periods ended September 30, 2018 and December 31, 2017. The Company believes that the carrying amounts of all remaining financial instruments approximate their fair value due to their relatively short maturities. |

Income Taxes | Note 7 – Income Taxes The Company provides for a valuation allowance when it is more likely than not that it will not realize a portion of the deferred tax assets. The Company has established a full valuation allowance for U.S. and foreign deferred tax assets due to the uncertainty that enough taxable income will be generated in those taxing jurisdictions to utilize the assets. Therefore, the Company has not reflected any benefit of such deferred tax assets in the accompanying consolidated financial statements. As of September 30, 2018, there were no material changes to what the Company disclosed regarding tax uncertainties or penalties in its Annual Report on Form 10-K for the year ended December 31, 2017. |
