Patent number: 7611523Abstract: An anastomosis device is a one piece device for connecting a graft vessel to a target vessel without the use of conventional sutures. The anastomosis device includes an expandable tube configured to have a graft vessel secured to the tube. The device has an expandable linkage positioned at one end of the device and expansion of this linkage causes a first radially extending flange to fold outward. This first flange abuts an interior wall of a target vessel and a second flange is formed which abuts an exterior wall of the target vessel trapping the target vessel between the two flanges and secures the end of the graft vessel into an opening in the wall of the target vessel. The device greatly increases the speed with which anastomosis can be performed over known suturing methods and allows anastomosis to be performed in tight spaces.Type: GrantFiled: September 18, 2003Date of Patent: November 3, 2009Assignee: Cardica, Inc.Inventors: Jaime Vargas, Stephen A. Yencho, Jamey Nielsen, Michael Hendricksen, Bernard A. Hausen

Publication number: 20070119902Abstract: A surgical stapler may include a staple holder, an anvil connected to the staple holder, where at least one of the staple holder and the anvil may be movable relative to the other, and where the anvil may include a groove defined therein, and a cutter that may be slidable along the groove in the anvil. Such a stapler may be used for treating a tissue structure having a lumen defined therein and a wall surrounding the lumen, such as by inserting the anvil into the lumen of the tissue structure through an opening in the wall of the tissue structure; and incising the wall of the tissue structure from the inside, utilizing the cutter.Type: ApplicationFiled: February 2, 2007Publication date: May 31, 2007Inventors: Jaime Vargas, Michael Hendricksen, Stephen Yencho, Jamey Nielsen, Bernard Hausen, Brendan Donohoe

Publication number: 20070106312Abstract: A method for connecting a graft vessel to a target vessel may utilize an integrated tool that includes a movable cam having a number of discrete slots defined therein. The method may include moving the cam, creating an opening in the wall of the target vessel with the integrated tool; and advancing an anastomosis device at least partially into the opening with the integrated tool, where moving the cam causes both the creating of the opening and the advancing of the anastomosis device.Type: ApplicationFiled: December 22, 2006Publication date: May 10, 2007Applicant: CARDICA, INC.Inventors: Jaime Vargas, Stephen Yencho, Jamey Nielsen, Michael Hendricksen, Bernard Hausen

Patent number: 7063712Abstract: 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: GrantFiled: September 24, 2002Date of Patent: June 20, 2006Assignee: Cardica, Inc.Inventors: Jaime Vargas, Michael Hendricksen, Stephen A.

Publication number: 20060116699Abstract: A method and system for performing anastomosis may use an anvil to control and support a tissue site during an anastomosis procedure involving tissue bonding techniques such as adhesive tissue bonding. Adhesive may be applied to mating surfaces of the graft and/or target vessels either before or after the vessels are brought into contact. Adhesive may be applied via an applicator associated with the anvil.Type: ApplicationFiled: January 13, 2006Publication date: June 1, 2006Inventors: David Bombard, Theodore Bender, Tenny Chang, Jaime Vargas, Michael Hendricksen, Stephen Yencho, Jamey Nielsen, Bernard Hausen, Brendan Donohoe

Patent number: 7014644Abstract: 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: April 30, 2002Date of Patent: March 21, 2006Assignee: Cardica, Inc.Inventors: David Bombard, Theodore Bender, Tenny Chang, Jaime Vargas, Michael Hendricksen, Stephen A.

Patent number: 6966920Abstract: The anastomosis device according to the present invention is a one piece device for connecting a graft vessel to a target vessel without the use of conventional sutures. The anastomosis device includes a frame for receiving and holding the end of a graft vessel in an everted position and first and second spreading members configured to be inserted into an opening in the target vessel. The first and second spreading members are arranged substantially in a plane for insertion into an opening in a target vessel, and are moved away from one another to capture the edges of the opening in the target vessel securing the graft vessel to the target vessel. One version of the anastomosis device includes a plurality of linkages arranged in two rows for grasping opposite sides of an opening in the target vessel. A portion of the linkages fold outward to trap vessel walls on opposite sides of the opening in the target vessel.Type: GrantFiled: December 30, 2002Date of Patent: November 22, 2005Assignee: Cardica, Inc.Inventors: Stephen A.
