Publication number: 20050033330Abstract: A method for performing anastomosis between a graft vessel and a target vessel with an integrated anastomosis tool may include actuating at least one control on the integrated anastomosis tool to create an opening in the target vessel and complete an anastomosis with the target vessel. Another method for performing anastomosis may include creating an opening in intact tissue of the target vessel with an integrated anastomosis tool; and deploying an anastomosis device with the integrated anastomosis tool. The anastomosis may be performed with an anastomosis device, such as an anastomosis device having a deployable section detachable from a discard section.Type: ApplicationFiled: September 3, 2004Publication date: February 10, 2005Inventors: Jaime Vargas, Stephen Yencho, James Nielsen, Brendan Donohoe, Theodore Bender, Brian DuBois, Scott Chamness, Nathan White, Gregory Arcenio, Heather Klaubert, Russell Mead

Publication number: 20050004591Abstract: An piercing member is axially fixed to and positioned within a cutter, both of which are components of a stand-alone tool for creating an opening in the wall of a tubular tissue structure. The stand-alone tool includes an impulse source connected to the piercing member and to the cutter. An actuator is operationally connected to the impulse source, where the actuator causes the impulse source to release energy to and provide an impulse to the piercing member and the cutter. The tool may be configured to make multiple openings in the tissue of the same patient.Type: ApplicationFiled: September 9, 2003Publication date: January 6, 2005Inventors: Theodore Bender, Brian DuBois, Dan Pomeroy, Scott Chamness, Brendan Donohoe

Publication number: 20040260342Abstract: An apparatus for performing anastomosis between a graft vessel and a target vessel may include a connector holder having spaced-apart arms, and a member connected to the connector holder, where the member is insertable through an opening in a wall of the target vessel at least partially into the lumen of the target vessel. One or more connectors, such as staples, may be deployed from each arm to connect the graft vessel to the target vessel. One or more connectors may be deformable against the member.Type: ApplicationFiled: July 23, 2004Publication date: December 23, 2004Applicant: Cardica, Inc.Inventors: Jaime Vargas, Michael Hendricksen, Stephen A. Yencho, Jamey Nielsen, Bernard A. Hausen, Brendan Donohoe

Publication number: 20030028205Abstract: An anastomosis system and method uses an anvil to control and support a tissue site during an anastomosis procedure. The anvil is particularly useful for supporting a wall of a coronary artery during attachment of a graft vessel to the coronary artery because the wall of the coronary artery is very thin, difficult to grasp, and susceptible to tearing. In one method, the anvil is inserted into a pressurized or unpressurized target vessel and is pulled against an inner wall of the target vessel causing tenting of the thin tissue of the vessel wall. A graft vessel is then advanced to the anastomosis site and an end of the graft vessel is positioned adjacent and exterior of the target vessel. Staples are inserted through the tissue of the graft vessel and the target vessel by pivoting the arms of a staple holder towards the anvil. When the ends of the staples engage staple bending features on the anvil, the ends of the staples bend over securing the graft vessel and target vessel together.Type: ApplicationFiled: September 24, 2002Publication date: February 6, 2003Applicant: Cardica, Inc.Inventors: Jaime Vargas, Michael Hendricksen, Stephen A.

Patent number: 6398797Abstract: A method and system for performing anastomosis uses an anvil to control and support a tissue site during an anastomosis procedure involving tissue bonding techniques such as tissue welding and adhesive tissue bonding. The anvil is particularly useful for supporting a wall of a coronary artery during attachment of a graft vessel in a coronary artery bypass graft procedure. The anvil is inserted into a pressurized or unpressurized target vessel and is pulled against an inner wall of the target vessel causing tenting of the thin tissue of the vessel wall. A graft vessel is then advanced to the anastomosis site and an end of the graft vessel is positioned adjacent an exterior of the target vessel. When tissue welding is used, a graft vessel fixture is positioned over the tissue surfaces to be welded in order to clamp the graft and target vessel tissue together. The tissue contacting surfaces of the anvil and/or graft vessel fixture are provided with one or more energy applying surfaces.Type: GrantFiled: November 29, 2000Date of Patent: June 4, 2002Assignee: Cardica, Inc.Inventors: David Bombard, Theodore Bender, Tenny Chang, Jaime Vargas, Michael Hendricksen, Stephen A.
