1. A method of connecting a first hollow structure to a second hollow structure, comprising:
- creating an opening in a second hollow tissue structure;
providing a device having a housing and a plurality of rod segments attached to the housing, at least the distal ends of the plurality of rod segments being movable between a first position, where the distal ends of the rod segments are separated by a first distance, and a second position, where the distal ends of the rod segments are separated by a second distance, the second distance being greater than the first distance;
positioning at least a portion of each of the plurality of rod segments within the opening of the second hollow tissue structure;
moving at least the distal ends of each of the plurality of rod segments between the first position and the second position; and
creating an anastomosis between the first hollow structure and the second hollow structure.

Abstract
A stapler for stapling a tubular structure to another structure. The stapler has an anvil which is expandable from a collapsed position to an expanded position. The stapler has a recess which receives at least a portion of the tubular structure and a shoulder which receives an everted end of the tubular structure. A first actuator moves the anvil relative to the shoulder for compressing the structures which are to be stapled together. A second actuator is used for driving the staples through the structures to be stapled together.

14. A method of connecting a first hollow structure to a second hollow structure, comprising:
-
creating an opening in a second hollow tissue structure; providing a device having a housing and a plurality of rod segments attached to the housing, each of the plurality of rod segments having a proximal portion and a distal portion, each distal portion being configured to be more flexible than the proximal portion, each distal portion having a distal end, and at least the distal ends of each of the plurality of rod segments being movable between a first position, where the distal ends are separated by a first distance, and a second position, where the distal ends are separated by a second distance, the second distance being greater than the first distance; positioning at least a portion of each of the plurality of rod segments within the opening of the second hollow tissue structure while the plurality of rod segments are in the first position; moving the plurality of rod segments between the first position and the second position; and creating an anastomosis between the first hollow structure and the second hollow structure. - View Dependent Claims (15)
