Patent number: 6478210Abstract: A full-thickness resection system comprises a flexible endoscope and a stapling mechanism, wherein the endoscope is slidably received through at least a portion of the stapling mechanism. The stapling mechanism comprises an anvil and a stapling head mounted to the anvil so that the anvil and the stapling head are moveable with respect to one another between a tissue receiving position and a stapling position and wherein a gap formed between the stapling head and the anvil is larger in the tissue receiving position than it is in the stapling position. A position adjusting mechanism is provided for moving the anvil and the stapling head between the tissue receiving and stapling positions and a staple firing mechanism sequentially fires a plurality of staples from the stapling head across the gap against the anvil and through any tissue received in the gap and a knife cuts a portion of tissue received within the gap.Type: GrantFiled: January 23, 2002Date of Patent: November 12, 2002Assignee: Scimed Life Systems, Inc.Inventors: Ronald D. Adams, Roy H. Sullivan, III, Lauren O. Main, Peter K. Kratsch, George A. Nunez, Jurgen A. Kortenbach, Matt Solar, Gerhard F. Buess, Marc O. Schurr

Publication number: 20020052612Abstract: A soft and pliable surgical support mesh exhibiting increased resistance to inhabitation of infectious matter. The mesh includes a support trellis formed of multifilament yarns wherein the interstitial voids located between the filaments of said yarns are enclosed within an infection-impervious matrix. The meshes may be designed to be extremely thin yet retain the requisite strength for repairing soft tissue, which allows for a low profile when folded for delivery.Type: ApplicationFiled: December 18, 2001Publication date: May 2, 2002Inventors: Peter J. Schmitt, Ronald D. Adams

Publication number: 20020047036Abstract: The FTRD described comprises a removable cartridge body that contains a new load of staples and a new blade for use in the FTRD. The cartridge body can be removed and replaced with a new one once the staples have been used. Rotation of a main shaft by the physician causes the staples to be fired and the blade to be moved along a pre determined path to cut the stapled tissue. Tactile and audible feedback is given to the physician when the stapling phase is complete and the cutting phase is to begin.Type: ApplicationFiled: March 30, 2001Publication date: April 25, 2002Inventors: Roy H. Sullivan, Ronald D. Adams

Patent number: 5503796Abstract: Method for continuously extruding powdered, comminuted, or particulated feed material with a Conform extrusion machine or the like in cooperation with a forming wheel rotatably disposed within a portion of the Conform wheel to compress the feed material into a compacted feedstock. Compressing of the feed material into a compacted feedstock enables uniform and reliable conveyance of the feed material into the extrusion machine without unnecessarily subjecting the compressed feedstock to air or oxygen. An auxiliary shoe member conforming to the outer periphery of the forming wheel and to the Conform shoe enables separation of the compacted feedstock from the forming wheel. The auxiliary shoe directs the compacted feedstock into a passageway formed by the Conform machine extrusion wheel and extrusion shoe.Type: GrantFiled: February 27, 1995Date of Patent: April 2, 1996Assignee: The Southwire CompanyInventors: Uday K.

Patent number: 5395383Abstract: An applicator is provided for applying a sheet of surgical material, e.g., an adhesion barrier or other surgical fabric, to internal body tissue. The applicator includes an expandable operating tip which is insertable into an endoscopic tube through an incision in a body to enable a surgeon to apply the adhesion barrier or other surgical fabric to tissue inside the body. A preferred embodiment of the applicator includes a set of telescoping tubes comprising an outer delivery tube, a intermediate deployment tube, and a inner irrigation tube. An expandable spreader tip is mounted at the distal end of the irrigation tube and connected to the distal end of the deployment tube. By advancing the deployment tube and irrigation tube relative to the delivery tube, the spreader tip is exposed at the distal end of the delivery tube. The spreader tip is expanded by movement of the deployment tube relative to the irrigation tube to spread the adhesion barrier over the tissue.Type: GrantFiled: January 27, 1994Date of Patent: March 7, 1995Assignee: Ethicon, Inc.Inventors: Ronald D. Adams, Richard M. O'Grady, Robert L. Marvin, Jr., Mary B. Youtsler, Michael T. Brown

Patent number: 5325848Abstract: A tissue manipulator is provided which is insertable through an endoscopic tube to enable a surgeon to manipulate tissue inside a body cavity. The endoscopic tissue manipulator includes an expandable tissue manipulating frame adapted to expand transversely through a longitudinal slot in a support tube to provide a spatula-shaped platform which can be manipulated by rotation of the support tube about its longitudinal axis to engage and displace large body organs away from a desired surgical site in a body cavity. The frame consists of a plurality of flexible frame members or wires adapted to flex laterally outward through the longitudinal slot in the support tube into a bow-shaped configuration overlapping the other frame members or wires of the spatula-shaped platform. The instrument can be provided with a single tissue manipulating frame or a pair of frames which are expandable through separate longitudinal slots in the support tube to provide a pair of spatula-shaped platforms to engage the tissue.Type: GrantFiled: September 10, 1992Date of Patent: July 5, 1994Assignee: Ethicon, Inc.Inventors: Ronald D.
