EXPLANATORY STATEMENT: DEREGISTRATION OF SECURITIES

This Post-Effective Amendment relates to the Registration Statement (333-108404) filed on Form S-4 with respect to the acquisition of assets by Enpath Medical, Inc. (formerly Medamicus, Inc).

On June 15, 2007 (the “Effective Date”), Enpath Medical, Inc., a Minnesota corporation (the “Company”) consummated the transactions contemplated by its Agreement and Plan of Merger, dated April 28, 2007 (the “Merger Agreement”) with Greatbatch, Ltd. (“Purchaser”), an indirect subsidiary of Greatbatch, Inc. (“Greatbatch”), and Chestnut Acquisition Corporation, a wholly owned subsidiary of Purchaser, pursuant to which the Company became a wholly-owned subsidiary of Purchaser. In accordance with the Merger Agreement, the Company’s prior common stock, par value $0.01 per share (the “Common Stock”), has been canceled and is no longer outstanding.

As a result of the consummation of the transactions contemplated by the Merger Agreement, the Company has terminated the offerings of the Company’s securities pursuant to the Registration Statement. Accordingly, pursuant to the undertakings contained in this Registration Statement to remove from registration, by means of a post-effective amendment, any of the securities being registered that remain unsold at the termination of the offering, the Company is filing this Post-Effective Amendment to the Registration Statement to deregister all the shares of the Company’s Common Stock registered and reserved for issuance under this Registration Statement that remained unissued as of the Effective Date.
