Description

FIELD OF THE INVENTION

[0001] The present invention generally relates to surgical staplers, and more particularly, to devices and methods for holding and / or protecting tissue adjacent to the stapler head of a circular stapler.BACKGROUND

[0002] In certain types of surgical procedures, the use of surgical staples has become the preferred method of joining tissue and, as such, specially configured surgical staplers have been developed for these applications. For example, intra-luminal or circular staplers have been developed for use in surgical procedures involving the lower colon wherein sections of the lower colon are joined together after a diseased portion has been excised. Circular staplers useful for performing such procedures are disclosed, for example, in U.S. Pat. Nos. 5,104,025; 5,205,459; 5,285,945; and 5,309,927 which are each herein incorporated by reference in their respective entireties.

[0003] In general, a conventional circular stapler typically consists of an elongated shaf...
