Exhibit 4.2  

THIS WARRANT CERTIFICATE IS EXERCISABLE ON OR BEFORE, 

AND VOID AFTER, 5:00 P.M. CENTRAL TIME, OCTOBER 31, 2007 

WARRANTS TO PURCHASE COMMON STOCK OF  

ANGEION CORPORATION
  INCORPORATED UNDER THE LAWS OF THE STATE OF MINNESOTA

	No.	 	W-	 	Certificate for	 	Warrants
	THIS CERTIFIES THAT	 	
CUSIP 03462H 13 1

or
assigns, is the owner of the number of Warrants set forth above, each of which represents the right to purchase from Angeion Corporation, a Minnesota corporation (the "Company"), at any time on or
before 5:00 P.M. Central time, October 31, 2007, upon compliance with and subject to the conditions set forth herein and in the Warrant Agreement hereinafter referred to, one share
(subject to adjustments referred to below) of the Common Stock of the Company (such shares or other securities or property purchasable upon exercise of the Warrants being herein called the "Shares"),
by surrendering this Warrant Certificate, with the Purchase Form on the reverse side duly executed, at the principal office of Wells Fargo Bank Minnesota, N.A., or its successor, as warrant
agent (the "Warrant Agent"), and by paying in full, in cash or by certified or official bank check payable to the order of the Company, the exercise price of $7.79 per share. 

        Upon
any exercise of less than all the Warrants evidenced by this Warrant Certificate, there shall be issued to the holder a new Warrant Certificate in respect of the Warrants as to
which this Warrant Certificate was not exercised. 

        Upon
the surrender for transfer or exchange of any Warrant Certificates, properly endorsed, to the Warrant Agent, the Warrant Agent at the Company's expense will issue and deliver to the
order of the holder hereof, a new Warrant Certificate or Warrant Certificates of like tenor, in the name of such holder or as such holder (upon payment by such holder of any applicable transfer taxes)
may direct, calling in the aggregate on the face or faces thereof for the number of shares of Common Stock called for on the face hereof. 

        The
Warrant Certificates are issued only as registered Warrant Certificates. Until this Warrant Certificate is transferred in the Warrant Register, the Company and the Warrant Agent may
treat the person in whose name this Warrant Certificate is registered as the absolute owner hereof and of the Warrants represented hereby for all purposes, notwithstanding any notice to the contrary. 

        This
Warrant Certificate is issued under the Warrant Agreement dated as of October 25, 2002 between the Company and the Warrant Agent. The Warrant Agreement is hereby incorporated
by reference into this Warrant Certificate and this Warrant Certificate is subject to the terms and provisions contained in said Warrant Agreement, to all of which terms and provisions the registered
holder of this Warrant Certificate consents by acceptance hereof. Copies of said Warrant Agreement are on file at the office of the Warrant Agent in Minneapolis, Minnesota, and may be obtained by
writing to the Warrant Agent. 

        The
number of Shares receivable upon the exercise of the Warrants represented by this Warrant Certificate and the exercise price per share are subject to adjustment upon the happening of
certain events specified in the Warrant Agreement. 

        No
fractional Shares of the Company's Common Stock will be issued upon the exercise of Warrants. As to any final fraction of a share which a holder of Warrants exercised in the same
transaction would otherwise be entitled to purchase on such exercise, the Company shall pay a cash adjustment in lieu of any fractional Share determined as provided in the Warrant Agreement. 

        The
Warrants may be redeemed at the option of the Company, at any time commencing after January 1, 2004, and following a period of ten (10) consecutive trading days after
January 1, 2004 where the per share closing price of the Common Stock (as set forth or defined in the Warrant Agreement) exceeds $9.73, on notice as set forth in the Warrant Agreement, and at a
redemption price equal to $.01 per Warrant. If notice of redemption shall have been given as provided in the Warrant Agreement and cash sufficient for the redemption be deposited by the Company for
that purpose, the exercise rights of the Warrants identified for redemption shall expire at the close of business on such date of redemption unless extended by the Company. 

        This
Warrant Certificate shall not entitle the holder hereof to any of the rights of a holder of Common Stock of the Company, including, without limitation, the right to vote, to receive
dividends and other distributions, to exercise any preemptive right, or to receive any notice of, or to attend meetings of holders of Common Stock or any other proceedings of the Company. 

        This
Warrant Certificate shall be void and the Warrants and any rights represented hereby shall cease unless exercised on or before 5:00 P.M. Central time on October 31,
2007, unless extended by the Company. 

        This
Warrant Certificate shall not be valid for any purpose until it shall have been countersigned by the Warrant Agent.
