Patent number: 6258111Abstract: A surgical cutting system. The cutting system includes a cutter which has an inner sleeve that moves adjacent to an aspiration port of an outer sleeve. The inner sleeve is coupled to a source of vacuum that pulls tissue into the outer port when the inner sleeve is moved away from the port. The inner sleeve then moves across the outer port and severs the tissue in a guillotine fashion. The tip of the inner sleeve may exert a spring force that assist in the cutting action of the cutter. The cutter includes a motor which creates an oscillating translational movement of the sleeve. The motor can be controlled by a controller that is coupled a foot pedal. The foot pedal and controller can be configured so that the motor decreases speed as the pedal is depressed by the operator. The inner sleeve is coupled to an aspiration line that pulls the severed tissue out of the cutter. The level of the aspiration vacuum pressure can be controlled by a variable regulator valve.Type: GrantFiled: August 5, 1999Date of Patent: July 10, 2001Assignee: Scieran Technologies, Inc.Inventors: Rod Ross, Greggory Hughes, James C. Boore, Thomas E. Reimer

Patent number: 6245090Abstract: A transcatheter occluding implant (50) is used to seal off a vessel lumen such as for arterial and venous embolization, cutting off of supply to tumors, male and female sterilization. There is illustrated a plug member of an open foam plastics material having good hysteresis properties in the form of a shaft 51 carrying annular supports. The implant (50) can be compressed into a very small size and then will expand to contact the internal bore of the vessel to form a force fit within the vessel lumen for secure anchoring of the implant. The open cell foam construction encourages tissue growth and thus further contributes to the stabilization of the implant.Type: GrantFiled: November 9, 1998Date of Patent: June 12, 2001Assignee: Salviac LimitedInventors: Paul Gilson, Eamon Brady

Patent number: 6126675Abstract: A device for sealing puncture wounds in blood vessels is open at one end and closed at the other end. The tube closure is generally flat and pivotable, and the tube region near the closed end is expandable. The device is initially contained in a sleeve, which is inserted through a cannula, so that the closed end is within the vessel to be sealed. After the cannula is removed, the closure is pivoted and the device withdrawn to a point where the closure abuts the puncture wound. After the sleeve is removed, the expandable region is expanded, so that the blood vessel wall around the puncture is sandwiched between the closure and the expanded region. The device prevents blood from seeping out of the punctured vessel during the healing process.Type: GrantFiled: January 11, 1999Date of Patent: October 3, 2000Assignee: Ethicon, Inc.Inventors: Semyon Shchervinsky, Louis Thomas Divilio, Claude Clerc

Patent number: 6113612Abstract: A connector for use in providing an anastomotic connection between two tubular body fluid conduits in a patient. The connector is preferably a single, integral, plastically deformable structure that can be cut from a tube. The connector has axial spaced portions that include members that are radially outwardly deflectable from other portions of the connector. The connector is annularly enlargeable so that it can be initially delivered and installed in the patient in a relatively small annular size and then annularly enlarged to provide the completed anastomosis. The radially outwardly deflected members of the first and second portions respectively engage the two body fluid conduits connected at the anastomosis and hold those two conduits together in fluid-tight engagement. Apparatus for use in delivering and deploying a connector is also disclosed.Type: GrantFiled: November 6, 1998Date of Patent: September 5, 2000Assignee: St. Jude Medical Cardiovascular Group, Inc.Inventors: William J.

Patent number: 6110188Abstract: A method for sealingly joining a graft vessel to a target vessel at an anastomosis site, the target vessel having an opening formed therein. The method includes positioning a fastener made from a deformable material radially adjacent to a free end portion of the graft vessel. The material is transformable between a non-fluent state and a fluent state, upon application of energy to the material. The method further includes inserting at least the free end portion of the graft vessel in the target vessel through the opening in the target vessel. Energy is then supplied to the deformable material at an intensity sufficient to transform the material into the fluent state. The free end portion of the graft is radially expanded to expand the graft vessel into intimate contact with an inner wall of the target vessel. The energy supply is discontinued so that the material returns to its non-fluent state to sealingly secure the graft vessel to the target vessel.Type: GrantFiled: March 9, 1998Date of Patent: August 29, 2000Assignee: Corvascular, Inc.Inventor: Hugh L. Narciso, Jr.

Patent number: 6106545Abstract: A suture tensioning and fixation device comprises a suture thread and a suture retaining element. The retaining element has a first suture thread engaging portion on the first end, a second suture thread engaging portion opposite the first suture thread engaging portion, and a third, substantially centrally located suture thread engaging portion. The retaining element is adapted such that segments of the suture thread can be interwoven between the suture thread engaging portions of the retaining element. The suture thread engaging portions of the retaining element are adapted to frictionally hold the interwoven segments of suture thread. Localized melting of the retaining element where it contacts the suture thread segments establishes a weld and bonds the suture thread to the retaining element in a knotless joint.Type: GrantFiled: April 16, 1998Date of Patent: August 22, 2000Assignee: Axya Medical, Inc.Inventor: Thomas D. Egan

Patent number: 6102922Abstract: A surgical method for reducing the food intake of a patient includes the steps of dissecting the lower part of the Esophagus, applying a band to form a loop around the Esophagus, displacing an upper part of the stomach through the loop, so as to form a small pouch above said band in connection with the Esophagus, and suturing the upper part to the stomach portion situated below the band loop, thereby tunnelating said band. A device useful in performing this method includes an elongated band having a flexible substantially non-expansible outer wall and a flexible and expansible inner wall joined to the outer wall to form an expansible closed cavity. The band has a length such that, when its ends are joined to each other, it forms a loop around the Esophagus, while permitting an upper part of the stomach to be introduced through the opening of the loop. A conduit extends between the band's cavity and an injection port.Type: GrantFiled: June 29, 1998Date of Patent: August 15, 2000Assignee: Kirk Promotions LimitedInventors: Arne Jakobsson, Peter Forsell

Patent number: RE36974Abstract: The present invention is an anchor for securing a suture in the body. The anchor includes a tubular wall having a central axis. The tubular wall has a proximal end and a distal end each free of axially inwardly extending slots. The tubular wall has an inner surface extending for the entire length of the tube and defining in the anchor a central opening extending between the proximal end and the distal end. The anchor has a width less than its length. A suture may extend through the anchor within the central opening. First and second end portions of the suture extend out of opposite ends of the anchor and are sufficiently long to project out of the body when the suture is secured in the body by the anchor. The anchor has an anchoring orientation in the body achieved by manipulation of the distal end of the anchor by pulling on the second end portion of the suture.Type: GrantFiled: March 2, 1998Date of Patent: November 28, 2000Inventor: Peter M.
