EXHIBIT 3.2 BYLAWS OF CARDIA, INC. ARTICLE I OFFICES AND CORPORATE SEAL Section 1.01. Registered and Other Offices. The registered office of the corporation in Minnesota shall be that set forth in the Articles of Incorporation or in the most recent amendment of the Articles of Incorporation or statement of the Board of Directors filed with the Secretary of State of Minnesota changing the registered office in the manner prescribed by law. The corporation may have such other offices, within or without the State of Minnesota, as the Board of Directors shall, from time to time, determine. Section 1.02. Corporate Seal. If so directed by the Board of Directors, the corporation may use a corporate seal. The failure to use such seal, however, shall not affect the validity of any documents executed on behalf of the corporation. The seal need only include the word "seal", but it may also include, at the direction of the Board, such additional wording as is permitted by law. ARTICLE II MEETINGS OF SHAREHOLDERS Section 2.01. Time and Place of Meetings. Annual or special meetings of the shareholders, if any, shall be held on the date and at the time and place fixed by the Chairman or Co-Chairman of the Board of Directors, or if a Chairman of the Board of Directors has not been elected, by the President or the Chief Executive Officer in the absence of Board action, or the Board, except that a special meeting called by, or at the demand of a shareholder or shareholders, shall be held in the county where the principal executive office is located. Section 2.02. Annual Meetings. Annual meetings of the shareholders shall be considered and treated as regular meetings of the shareholders under Chapter 302A of the Minnesota Statutes. No meeting shall be considered an annual meeting unless specifically designated as such in the notice of meeting or unless all the shareholders are present in person or by proxy and none of them objects to such designation. At any annual meeting of the shareholders there shall be an election of qualified successors for directors who serve for an indefinite term and whose terms have expired or are due to expire within six (6) months after the date of the meeting. Any business appropriate for action by the shareholders may be transacted at an annual meeting. To be properly brought before the meeting, business must be of a nature that is appropriate for 1 consideration at an annual meeting and must be (i) specified in the notice of meeting (or any supplement thereto) at the direction of the Board of Directors, (ii) otherwise properly brought before the meeting by or at the direction of the Board of Directors, or (iii) otherwise properly brought before the meeting by a shareholder (as the term "shareholder" is defined in Chapter 302A of the Minnesota Statutes). In addition to any other applicable requirements, for matters to be properly brought before the annual meeting by a shareholder, the shareholder must have given timely notice thereof in writing to the Secretary of the corporation. To be timely, each such notice must be given, either by personal delivery or delivery by United States mail, postage prepaid, addressed to the Secretary of the corporation at the registered office of the corporation, not less than 45 days nor more than 75 days prior to a meeting date corresponding to the previous year's annual meeting. Risk of non-delivery shall rest on whose behalf the attempted delivery is made. Each such notice to the Secretary shall set forth as to each matter the shareholder proposes to bring before the annual meeting (i) a brief description of the business desired to be brought before the annual meeting and the reasons for conducting such business at the annual meeting, (ii) the name and address of record of the shareholders proposing such business, (iii) the class or series (if any) and number of shares of the corporation which are owned by the shareholder, (iv) any material interest of the shareholder in such business, and (v) such other information regarding such proposed business as would be required to be included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission. Notwithstanding anything in these Bylaws to the contrary, no business shall be transacted at the annual meeting except in accordance with the procedures set forth in this Article; provided, however, that nothing in this Article shall be deemed to preclude discussion by any shareholder of any business properly brought before the annual meeting in accordance with these Bylaws. Section 2.03. Demand by Shareholders. Annual or special meetings may be demanded by a shareholder or shareholders, pursuant to the provisions of Minnesota Statutes, Sections 302A.431, Subd. 2, and 302A.433, Subd. 2, respectively, or any successor statutes. Section 2.04. Quorum, Adjourned Meetings. The holders of a majority of the voting power of the shares entitled to vote at a meeting constitute a quorum for the transaction of business; said holders may be present at the meeting either in person or by proxy. In the absence of a quorum, any meeting may be adjourned to a subsequent date, provided a notice of such adjournment is mailed to each shareholder entitled to vote at least five (5) days before such adjourned meeting. If a quorum is present, a meeting may be adjourned from time to time without notice other than announcement at such meeting. At adjourned meetings at which a quorum is present, any business may be transacted which might have been transacted at the meeting as originally noticed. If a quorum is present when a duly called or held meeting is convened, the shareholders present may continue to transact business until adjournment, even though withdrawal of shareholders originally present leaves less than the proportion or number otherwise required for a quorum. Section 2.05. Voting. At each meeting of the shareholders, every shareholder having the right to vote shall be entitled to vote either in person or by proxy. Unless otherwise provided by 2 the Articles of Incorporation or a resolution of the Board of Directors filed with the Secretary of State, each shareholder shall have one vote for each share held. Upon demand of any shareholder, the vote upon any question before the meeting shall be by ballot. Section 2.06. Closing of Books. The Board of Directors may fix a time, not exceeding sixty (60) days preceding the date of any meeting of shareholders, as a record date for the determination of the shareholders entitled to notice of, and to vote at, such meeting, notwithstanding any transfer of shares on the books of the corporation after any record date so fixed. The Board of Directors may close the books of the corporation against the transfer of shares during the whole or any part of such period. If the Board of Directors fails to fix a record date for determination of the shareholders entitled to notice of, and to vote at, any meeting of shareholders, the record date shall be the twentieth (20th) day preceding the date of such meeting. Section 2.07. Notice of Meetings. Notice of all meetings of shareholders shall be given to every holder of voting shares, except where the meeting is an adjourned meeting at which a quorum was present and the date, time and place of the meeting were announced at the time of adjournment. The notice shall be given at least five (5) but not more than sixty (60) days before the date of the meeting except that written notice of a meeting at which there is to be considered either (i) an agreement of merger or consolidation, (ii) a proposal to dispose of all or substantially all of the property and assets of the corporation, (iii) a proposal to dissolve the corporation, or (iv) a proposal to amend the Articles of Incorporation, shall be mailed to all shareholders, whether entitled to vote or not, at least fourteen (14) days prior thereto. Every notice of any special meeting shall state the purpose or purposes for which the meeting has been called, and the business transacted at all special meetings shall be confined to the purpose stated in the call, unless all of the shareholders are present in person or by proxy and none of them objects to consideration of a particular item of business. Section 2.08. Waiver of Notice. A shareholder may waive notice of any meeting of shareholders. A waiver of notice by a shareholder entitled to notice is effective whether given before, at or after the meeting and whether given in writing, orally or by attendance. Section 2.09. Authorization Without a Meeting. Any action required or permitted to be taken at a meeting of the shareholders may be taken without a meeting by written action signed by all of the shareholders entitled to vote on that action. ARTICLE III DIRECTORS Section 3.01. General Powers.

Except as otherwise provided, each director shall be elected by the shareholders to hold office for a term of three consecutive years. Each director shall serve until his or her successor shall have been elected or until he or she shall retire, resign, die or shall have been removed as hereinafter provided. Section 3.03. Vacancies. Any vacancies occurring in the Board of Directors for any reason, and any newly created directorships resulting from an increase in the number of directors, may be filled by a majority of the directors then in office. Any directors so chosen shall hold office until the next election of directors at an annual or special meeting of shareholders and until their successors shall be elected subject, however, to prior retirement, resignation, death or removal from office. Section 3.04. Quorum. A majority of the directors then in office shall constitute a quorum for the transaction of business, and if at any meeting of the Board of Directors there shall be less than said quorum, a majority of those present may adjourn the meeting from time to time. If a quorum is present when a duly called or held meeting is convened, the directors present may continue to transact business until adjournment, even though withdrawal of directors originally present leaves less than the proportion or number otherwise required for a quorum. Section 3.05. Director Nominations. Nominations for the election of directors may be made by the Board of Directors or a committee appointed by the Board of Directors or by any shareholders entitled to vote generally in the election of directors. Any shareholder (as the term "shareholder" is defined in Chapter 302A of the Minnesota Statutes) entitled to vote generally in the election of directors may nominate one or more persons for election as directors at the annual meeting only if written notice of such shareholder's intent to make such nomination or nominations has been given, either by personal delivery or by United States mail, postage prepaid, to the Secretary of the corporation not less than 45 days nor more than 75 days prior to a meeting date corresponding to the previous year's annual meeting. Risk of non-delivery shall rest on the person on whose behalf the attempted delivery is made. Each such notice to the Secretary shall set forth: (i) the name and address of record of the shareholder who intends to make the nomination; (ii) a representation that the shareholder is a holder of record of shares of the corporation entitled to vote at such meeting and the person or persons specified in the notice; (iii) the name, age, business and residence addresses, and principal occupation or employment of each nominee; (iv) a description of all arrangements or understandings between the shareholder and each nominee and any other person or persons (naming such person or persons) pursuant to 4 which the nomination or nominations are to be made by the shareholder; (v) such other information regarding each nominee proposed by such shareholder as would be required to be included in a proxy statement filed pursuant to the proxy rules of the Securities and Exchange Commission; and (vi) the consent of each nominee to serve as a director of the corporation if so elected. The corporation may require any proposed nominee to furnish such other information as may reasonably be required by the corporation to determine the eligibility of such proposed nominee to serve as a director of the corporation. The presiding officer of the meeting may, if the facts warrant, determine that a nomination was not made in accordance with the foregoing procedure, and if he or she should so determine, it shall be so declared at the meeting and the defective nomination shall be disregarded.

Section 3.08. Notice of Meetings. If the meeting is a regular meeting of the Board, or if the date and time of a Board meeting has been announced at a previous meeting, no notice is required. Otherwise, notice of a meeting of the Board of Directors shall be given by the Secretary, Chief Executive Officer or President who shall give at least seventy-two (72) hours' notice thereof to each director by mail, telephone, telegraph or in person. The notice need not state the purpose of the meeting. Section 3.9. Waiver of Notice. Notice of any meeting of the Board of Directors may be waived by a director either before, at, or after such meeting in a writing signed by such director; provided, however, that a director, by his or her attendance and participation in any action taken at the meeting of the Board of Directors, shall be deemed to waive notice of such meeting. Section 3.10. Committees of the Board. The Board of Directors may, in its discretion, by the affirmative vote of a majority of the directors, appoint committees which shall have and may exercise such powers as shall be conferred or authorized by the resolutions appointing them. A majority of any such committee, if the committee be composed of more than two members, may determine its action and fix the time and place of its meetings, unless the Board of Directors shall otherwise provide. The Board of Directors shall have power at any time to fill vacancies in, to change the membership of, or to discharge any such committee. Section 3.11. Compensation of Directors. Directors who are not salaried officers of this corporation may receive any combination of a fixed sum per meeting attended, a fixed annual 5 sum and/or such other compensation, including stock options and stock grants, as may be determined, from time to time, by resolution of the Board of Directors. All directors may receive reimbursement of expenses, if any, for attendance at meetings of the Board of Directors or any committee thereof. Nothing herein contained shall be construed to preclude any director from serving this corporation in any other capacity and receiving compensation for such other service. Section 3.12. Absent Directors. A director may give advance written consent or opposition to a proposal to be acted on at a Board of Directors' meeting. Section 3.13. Authorization without a Meeting.

Electronic Communications. A director or committee member may participate in a meeting by any means or communication through which such person, other persons so participating, and all persons physically present at the meeting may simultaneously hear each other during the meeting. Participation in a meeting by that means constitutes presence in person at the meeting. A conference among directors or committee members by any means of communication through which such persons may simultaneously hear each other during the conference is a meeting of the Board of Directors or committee, as the case may be, if the same notice is given of the conference as would be required for a meeting, and if the number of persons participating in the conference would be sufficient to constitute a quorum at a meeting. Participation in a meeting by that means constitutes presence in person at the meeting. ARTICLE IV OFFICERS Section 4.01. Number and Offices.
