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: 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.

Publication number: 20040249415Abstract: A method for tensioning incisions made in a target vessel during an anastomosis procedure is provided. After an incision is made in a target vessel, incision tensioners are placed within the incision in order to tension the incision. The incision is tensioned when the incision tensioners are pulled taut in order to stretch the incision to a predetermined length or a predetermined force. The tensioners allow for proper grafting of a graft vessel to the target vessel in an end to side anastomosis. In addition, the incision tensioners allow the incision to have a known geometry, thereby allowing precise grafting of the graft vessel to the target vessel during the anastomosis procedure. After the incision is tensioned, the graft vessel is grafted to the target vessel using clips, sutures, staples or other anastomosis devices. One example of anastomosis clips are configured to capture the graft vessel and the target vessel such that the graft vessel grafts with the target vessel.Type: ApplicationFiled: May 11, 2004Publication date: December 9, 2004Applicant: Cardica, Inc.Inventors: Jaime Vargas, Tenny Chang, David Bombard

Publication number: 20040236178Abstract: A method for preparing a graft vessel for anastomosis to a target vessel includes making at least one incision in the graft vessel, such as to form a flap at an end thereof. The graft vessel and/or a fixture, such as a clamp, may be positioned relative to one another, such as to form an angle relative to one another, prior to making the incision or incisions. The position of the graft vessel relative to the fixture may be based on the size of the opening in the target vessel at the anastomosis site.Type: ApplicationFiled: June 18, 2004Publication date: November 25, 2004Applicant: Cardica, Inc.Inventors: Jaime Vargas, Ted Bender, David Bombard, Jeremy Frank

Publication number: 20040210244Abstract: 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: ApplicationFiled: September 4, 2001Publication date: October 21, 2004Applicant: Cardica, Inc.Inventors: Jaime Vargas, Stephen A. Yencho, Jamey Nielsen, Michael Hendricksen, Bernard A. Hausen

Publication number: 20040204754Abstract: A prosthesis includes a radially expansible scaffold in at least two circumferential anchors extending from the scaffold. The prosthesis is placed across an os between a main body lumen and a branch lumen. The scaffold is expanded within the branch lumen and the circumferential anchors deformed outwardly to conform to the wall of the main body lumen. Optionally, a second prosthesis may be placed within the main body lumen after the first prosthesis has been deployed.Type: ApplicationFiled: March 23, 2004Publication date: October 14, 2004Applicant: Anvil Medical, Inc.Inventors: Aaron V. Kaplan, Jaime Vargas

Publication number: 20040181245Abstract: An implantable superelastic anastomosis device may include a substantially continuous ring, the diameter of which may be substantially fixed. The anastomosis device may include first flange members and second flange members extending from an open central structure, where at least one second flange member has a free end oriented generally toward at least one first flange member after the anastomosis device has been deployed.Type: ApplicationFiled: March 26, 2004Publication date: September 16, 2004Applicant: Cardica, Inc.Inventors: Stephen Yencho, Jaime Vargas

Patent number: 6786862Abstract: A graft vessel preparation device and a method for using the graft vessel preparation device is provided. The graft vessel preparation device establishes and maintains a critical dimension on a graft vessel which corresponds to a dimension of an anastomosis site on a target vessel. One example of a graft vessel preparation device which prepares a graft vessel for a vascular anastomosis procedure includes a parallelogram linkage, a first spreader arm and a second spreader arm. The first spreader arm and the second spreader arm mount on opposing members of the parallelogram linkage in a parallel configuration. The spreader arms are configured in order to allow the placement of an end of a graft vessel over the spreader arms. The spreader arms are also configured to separate within an interior of the graft vessel once the graft vessel is placed over the spreader arms in order to establish a critical dimension. The critical dimension is established using a critical dimension locator.Type: GrantFiled: February 14, 2003Date of Patent: September 7, 2004Assignee: Cardica, Inc.Inventors: Jaime Vargas, Ted Bender, David Bombard, Jeremy Frank

Publication number: 20040167550Abstract: An integrated anastomosis tool both creates an opening in a side wall of a target blood vessel and performs an anastomosis procedure to connect a graft vessel to a side of the target blood vessel with a single integrated tool. The integrated anastomosis tool includes a cutting device, a graft vessel attachment device, an introducer, and a tool body. In each of the embodiments of the anastomosis tool, the advancement paths of a cutting device and a graft vessel attachment device cross, intersect, or align so that both the cutting device and the graft vessel attachment device can be operated by a single tool at the same intended anastomosis site in a sequential manner. The anastomosis procedure can be performed on a pressurized vessel since there is no need to interchange tools during the procedure.Type: ApplicationFiled: February 27, 2004Publication date: August 26, 2004Applicant: Cardica, Inc.Inventors: Brendan M.

Patent number: 6776785Abstract: A one piece anastomosis device is disclosed which is formed of a superelastic or pseudoelastic material which self deforms or self deploys from an insertion configuration to a tissue holding configuration. The device in a deployed state preferably includes an inner tissue penetrating flange which penetrate and retains an everted graft vessel and an outer flange. The self deploying anastomosis device does not rely on a temperature transformation to achieve deployment.Type: GrantFiled: October 12, 2000Date of Patent: August 17, 2004Assignee: Cardica, Inc.Inventors: Stephen Yencho, Jaime Vargas
