| Pay vs Performance Disclosure [Table] | | | | | |
| Pay vs Performance [Table Text Block] | | | The following table sets forth compensation of our CEO (the Principal Executive Officer, referred to in this section as “PEO”) and our other named executive officers (the “Non-PEO NEOs”), on an average basis, along with total shareholder return, net income, and total revenue for our fiscal years 2022, 2021, and 2020.

Reuvers was our PEO in each of 2022 and 2021, as well as in 2020 starting on June 8, 2020. Gerald R. Mattys served as our PEO in 2020 through June 8 2020. In 2022 and 2021, Brent Moen, Kristie Burns and Eric Pauls were our Non-PEO NEOs. In 2020, Brent Moen, Robert Folkes and Bryan Rishe were our Non-PEO NEOs. (2) The dollar amounts reported represent the Compensation Actually Paid (“CAP”) to the NEOs in accordance with, and using the adjustments set forth in, Item 402(v) of Regulation S-K. The following adjustments related to equity awards were made to their total compensation each year as reported in the Summary Compensation Table (“SCT”) to determine the CAP: Reconciliation of PEO Summary Compensation Table Total to Compensation Actually Paid Year Reported SCT Total ($) Equity Award Adjustments ($) Compensation Actually Paid ($) 2022 3,220,584 (1,369,260) 1,851,324 2021 2,076,884 (1,617,407) 459,477 2020 (Current) 2,024,978 440,103 2,465,081 2020 (Former) 687,888 (1,844,256) (1,156,368) Reconciliation of Average Non-PEO NEO Summary Compensation Table Total to Compensation Actually Paid Year Reported SCT Total ($) Equity Award Adjustments ($) Compensation Actually Paid ($) 2022 1,166,401 (398,298) 768,103 2021 941,781 (582,719) 359,062 2020 1,391,233 (876,073) 515,160 (3) Our peer group for the calculation of total shareholder return (“TSR”) is the S&P Healthcare Equipment Select Industry Index, which is the industry index used in our stock price performance graph in our Form 10-K for the fiscal year ended December 31, 2022. TSR, in the case of both the Company and our peer group, reflects the cumulative return on $100 as if invested on December 31, 2019, including reinvestment of any dividends. ( 4) Our company-selected measure, which we believe represents the most important financial performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link CAP to the NEOs for 2022 to company performance, is revenue. Revenue is one of the metrics under both the 2022 annual cash incentive program and the 2022 PSUs. In order to calculate CAP, the following amounts were excluded from or added to the SCT total compensation: Current PEO Year Deduct: Grant Date Fair Value of Covered Year Equity Awards ($) Year End Fair Value of Covered Year Equity Awards ($) Year-over-Year Change in Fair Value of Equity Awards Granted in a Prior Year that were Unvested at End of Covered Year ($) Fair Value as of Vesting Date of Equity Awards Granted and Vested in the Covered Year ($) Year-over-Year Change in Fair Value of Equity Awards Granted in a Prior Year that Vested in the Covered Year ($) Fair Value at the End of the Prior Year of Equity Awards that Failed to Meet Vesting Conditions in the Covered Year ($) Value of Dividends or other Earnings Paid on Stock or Option Awards not Otherwise Reflected in Fair Value or Total Compensation ($) Total Equity Award Adjustments ($) 2022 (1,999,984) 1,081,241 (323,775) — (126,742) — — (1,369,260) 2021 (1,499,930) 598,713 (382,129) — (334,060) — — (1,617,407) 2020 (1,417,951) 1,858,054 — — — — — 440,103 In connection with his appointment as CEO in 2020, Mr. Reuvers received a grant of stock options that included a market condition related to stock price in order to vest. Due to that market condition, the grant date fair value of those stock options was determined using the Monte Carlo Simulation model. The market condition was satisfied in the first quarter of 2021, and as a result, we have used the Black-Scholes valuation model (which is the valuation model used for all other stock option awards we have granted) to value these stock options for all dates subsequent to the grant date as part of the CAP calculations.
