Publication number: 20090312807Abstract: A method of treating a patient's joint having opposing joint surfaces includes providing an elongate member having a proximal end, a distal end and an expandable member near the distal end. The expandable member is positioned in the joint between the joint surfaces and expanded so as to separate the joint surfaces away from one another into a distracted position. The joint is manipulated while in the distracted position so that the joint is distracted and in flexion. A diagnostic or therapeutic procedure is then performed on the joint while maintaining the joint in the flexed and distracted position.Type: ApplicationFiled: June 12, 2009Publication date: December 17, 2009Applicant: The Foundry, LLCInventors: David Boudreault, Vivek Shenoy, Hanson S.

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

Patent number: 7357807Abstract: 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: GrantFiled: February 27, 2004Date of Patent: April 15, 2008Assignee: Cardica, Inc.Inventors: Brendan M. Donohoe, Jaime Vargas, Stephen A. Yencho, James T. Nielsen, Theodore M. Bender, Michael Hendricksen, Scott C. Anderson

Publication number: 20080072914Abstract: Methods and devices are adapted for regulating fluid flow to and from a region of a patient's lung, such as to achieve a desired fluid flow dynamic to a lung region during respiration and/or to induce collapse in one or more lung regions. Pursuant to an exemplary procedure, an identified region of the lung is targeted for treatment. The targeted lung region is then bronchially isolated to regulate airflow into and/or out of the targeted lung region through one or more bronchial passageways that feed air to the targeted lung region.Type: ApplicationFiled: August 24, 2007Publication date: March 27, 2008Inventors: Michael Hendricksen, Antony Fields, Michael Barrett, Ronald Hundertmark, Alan Rapacki, Steve Wallace, Michael Regan, John McCutcheon

Patent number: 7309343Abstract: A tissue punch for creating a hole in the wall of a target blood vessel for receiving an anastomosis device includes a piercing element for penetrating the tissue and a cutting element for cutting a plug of tissue around the pierced hole. The tissue punch includes a trocar for inserting the piercing element. After punching is complete, the piercing element is removed from the trocar through a side wall of the trocar so that a medical device can be deployed through the trocar lumen. The tissue punch may also include a tissue trap for trapping the plug of tissue.Type: GrantFiled: October 31, 2003Date of Patent: December 18, 2007Assignee: Cardica, Inc.Inventors: Jaime Vargas, Brendan M.

Publication number: 20070233163Abstract: A surgical tool for performing anastomosis between a graft vessel and a target vessel may include an anvil; a cutting element connected to the anvil; and an energy source connected to the cutting element, wherein the energy source is configured to deliver energy to the cutting element. A method for performing anastomosis with that tool may include placing an end of the graft vessel against a side of the target vessel; creating an opening in the wall of the target vessel at a first location; inserting an anvil through the opening from outside the wall of the target vessel into the lumen of the target vessel; creating an incision in the wall of the target vessel spaced apart from the first location; and connecting the graft vessel to the target vessel.Type: ApplicationFiled: May 31, 2007Publication date: October 4, 2007Applicant: CARDICA, INC.Inventors: David Bombard, Bryan Knodel, Jaime Vargas, Michael Hendricksen, Stephen Yencho, James Nielsen, Bernard Hausen, Brendan Donohoe, Theodore Bender

Publication number: 20070043387Abstract: A tool that has an introducer having a space therein and a distal aperture at the distal end thereof, and a spike movable within the introducer, may be used in a surgical method for treating a vessel wall. A tissue plug may be removed from the vessel wall with the spike, whereby an opening remains in the vessel wall. The spike then may be moved within the space in the introducer in a direction away from the longitudinal centerline of the distal aperture. An object then may be delivered through the introducer and out of the distal aperture to the opening in the vessel wall.Type: ApplicationFiled: October 27, 2006Publication date: February 22, 2007Inventors: Jaime Vargas, Brendan Donohoe, Scott Anderson, Theodore Bender, Stephen Yencho, Bernard Hausen, Michael Hendricksen, James Nielsen

Patent number: 7175637Abstract: 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 4, 2001Date of Patent: February 13, 2007Assignee: Cardica, Inc.Inventors: Jaime Vargas, Stephen A.

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.
