Patent number: 11229831Abstract: A telemark ski binding has a toe retainer pivotally coupled to a base. A lock assembly of the binding has an actuator assembly. The lock assembly is adjustable between a locked configuration and an unlocked configuration. The binding further has a heel retainer rotatably coupled to the toe retainer. When the lock assembly is in the unlocked configuration, the toe retainer is unlocked, and the toe retainer and heel retainer are both rotatable together substantially inline, relative to the base, around a first center point. When the lock assembly is in the locked configuration, the toe retainer is locked, and the toe retainer is restrained from rotating relative to the base. The heal retainer is rotatable relative to the toe retainer around a second center point. The second center point is at a different location from said first center point.Type: GrantFiled: June 24, 2019Date of Patent: January 25, 2022Inventors: David Bombard, Erik M.

Patent number: 7041112Abstract: 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: GrantFiled: May 11, 2004Date of Patent: May 9, 2006Assignee: Cardica, Inc.Inventors: Jaime Vargas, Tenny Chang, David Bombard

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: 6882880Abstract: The change in tissue impedance due to the change in the extracellular matrix that results from the degradation of cartilage is utilized to detect degradation of articular cartilage. A probe includes electrodes that apply a current to the articular cartilage which results in a current distribution and electric field within the cartilage, along with an associated voltage drop across the electrodes. The amplitude of this voltage drop is then measured and divided by the current applied to determine the tissue impedance. By measuring the impedance of patient tissue and comparing the detected patient impedance to a normal value for the tissue from clinically normal tissue, a determination of whether the patient tissue is degraded, and a determination of the extent of degradation is possible. Preferably, the impedance is measured using a probe with interdigitated electrodes.Type: GrantFiled: December 19, 2002Date of Patent: April 19, 2005Assignee: Massachusetts Institute of TechnologyInventors: Steven Treppo, Alan J.

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

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
