THIS REPORT AMENDS THE REGISTRANT'S REPORT ON FORM 8-K ORIGINALLY FILED WITH THE
SECURITIES AND EXCHANGE COMMISSION ON JUNE 8, 2007.




Item 2.01 Completion of Acquisition or Disposition of Assets.

     On June 8, 2007, Greatbatch, Inc. ("Greatbatch") filed a Current Report on
Form 8-K (the "Original Form 8-K") to report that on June 6, 2007, as a result
of a tender offer and pursuant to an Agreement and Plan of Merger, dated as of
April 28, 2007, by and among Enpath Medical, Inc. ("Enpath"), Greatbatch Ltd.
("Parent"), an indirect wholly-owned subsidiary of Greatbatch, and Chestnut
Acquisition Corporation ("Purchaser"), a wholly-owned subsidiary of Parent,
Purchaser acquired approximately 90.1% of the outstanding common stock of
Enpath.

     Following the closing of the Enpath acquisition on June 15, 2007, and
subsequent to the filing of the Original Form 8-K, Greatbatch determined that
Enpath did not meet any of the conditions of a "significant subsidiary" as set
forth in Rule 1-02(w) of Regulation S-X that would require the filing of certain
financial statements and pro forma financial information with respect to Enpath.


Item 9.01. Financial Statements and Exhibits.

(a)  Financial statements of a business acquired.

     As set forth in Item 2.01 above, since the filing of the Original Form 8-K,
Greatbatch has determined that Enpath does not meet any of the conditions of a
"significant subsidiary" for purposes of Rule 3-05(b)(2) of Regulation S-X.
Accordingly, the filing of audited financial statements of Enpath is not
required by this item.

(b)  Pro forma financial information.

     As set forth in Item 2.01 above, since the filing of the Original Form 8-K,
Greatbatch has determined that Enpath does not meet any of the conditions of a
"significant subsidiary" for purposes of Rule 11-01(b)(1) of Regulation S-X.
Accordingly, the filing of unaudited pro forma financial information reflecting
the Enpath acquisition is not required by this item.
