Filed:

Jan 8, 2001

Appl. No.:

09/756426

Inventors:

Christopher F. Heck - Plymouth MN
Lee R. Bolduc - Mountain View CA

Assignee:

Hearport, Inc. - Redwood City CA

International Classification:

A61B 17068

US Classification:

2271761, 227 19, 2271791, 606219

Abstract:

The present invention provides a method and end-to-side surgical anastomosis apparatus for stapling an end of a tubular tissue structure to a side of a luminal structure including an elongated housing defining a central bore extending longitudinally therethrough. The elongated housing further includes an eversion support surface extending circumferentially about the bore opening adjacent the distal end which is configured to retain and support an everted end of the received tissue structure thereon to face an intimal surface of the tissue structure in an outward direction. The anastomosis apparatus further includes an anvil having a fastener engaging surface, and a compression device having a shoulder portion formed for selectively compressing the everted end of the tissue structure and a surface of the luminal structure together against the fastener engaging surface. The compression device is further formed to deform the fasteners into contact with the everted end of the tubular tissue structure and the luminal structure to create an anastomotic bond between the tubular tissue structure and the luminal structure. At least one driver pin, is preferably provided moveable relative to the compression device for ejecting the plurality of fasteners through the everted end of the tubular tissue structure and the luminal structure to engage the fastener engaging surface.

International Classification:

A61B 17068

US Classification:

2271761, 227 19, 2271791, 606219

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.
