Patent number: 8006889Abstract: 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 19, 2011Date of Patent: August 30, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Ronald D. Adams, Roy H. Sullivan, III, Lauren O. Main, Peter K. Kratsch, George A. Nunez, Jurgen A. Kortenbach, Matthew S. Solar, Gerhard F. Buess, Marc O. Schurr

Patent number: 7896215Abstract: Described is a full-thickness resection system which includes a control unit coupled to a proximal end of a flexible endoscope. The control unit remains outside of a body when the stapling head is in an operative position within a body lumen. The control unit includes (i) an anvil actuator coupled to an anvil in the stapling head, actuation of the anvil actuator moves the anvil axially relative to a stapling mechanism in the stapling head to compress a folded full-thickness portion of lumenal tissue between the anvil and the stapling mechanism. In addition, the control unit includes (ii) a stapler actuator coupled to the stapling mechanism in the stapling head, actuation of the stapler actuator causing the stapling mechanism to drive staples through the folded lumenal tissue against the anvil.Type: GrantFiled: June 11, 2009Date of Patent: March 1, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Ronald D.

Patent number: 5549606Abstract: An endoscopic bipolar electrocautery instrument includes a proximal actuator coupled by a tube and push rod to a pair of distal graspers. The tube is covered with an insulating shrink wrap from its distal end up to an uncovered proximal portion. A stationary jaw with an integral clevis is mounted inside the distal end of the tube and electrically contacts the inner surface thereof. The clevis holds a pair of ceramic insulators between which a movable jaw is mounted on an insulated bushing with an axle pin. The movable jaw is electrically and mechanically coupled to the push rod which is covered with an insulating shrink wrap from a point just proximal of its connection with the movable jaw to a point near its proximal end. The uninsulated proximal end of the tube is mounted in a conductive bushing which rotates within a nonconductive handle. The proximal end of the push rod extends beyond the conductive bushing and a rubber insulator is fitted between the bushing and the push rod.Type: GrantFiled: August 30, 1994Date of Patent: August 27, 1996Assignee: Symbiosis CorporationInventors: Michael S.

Patent number: 5542432Abstract: An endoscopic multiple sample bioptome includes a hollow outer member and an axially displaceable inner member extending therethrough. The proximal ends of the outer and inner members are coupled to an actuator for axially displacing one relative to the other. The distal end of the outer member is coupled to one of a cylinder having a sharp distal edge and a jaw assembly, while the distal end of the inner member is coupled to the other. The jaw assembly includes a pair of opposed, preferably toothed jaw cups each of which is coupled by a resilient arm to a base member. The arms are bent to urge the jaws away from each other. The base member is mounted inside the cylinder and axial movement of the jaw assembly and cylinder relative to each other draws the arms into the cylinder and brings the jaw cups together in a biting action.Type: GrantFiled: February 1, 1994Date of Patent: August 6, 1996Assignee: Symbiosis CorporationInventors: Charles R.

Patent number: 5507297Abstract: An endoscopic instrument has a distal assembly removable from a proximal handle. The distal assembly includes a tube carrying an end effector and a push rod coupled to the end effector and slidable through the tube. The proximal handle includes a tube sleeve for receiving the tube, an actuator and a latch for coupling the push rod to the actuator. The tube sleeve is provided with a tube lock for holding the tube securely in place and the tube is provided with a circumferential groove for engaging the lock. The latch is spring loaded, hinged, and has an inclined surface for quick coupling with the push rod. The latch also has a mechanism for uncoupling the latch from the push rod. The push rod is provided with a mating tip which engages the latch so that the actuator causes reciprocal movement of the push rod within the tube to operate the end effector. An axially movable collar on the tube sleeve is used in unlatching, and in one arrangement is also used for rotating the distal assembly.Type: GrantFiled: February 11, 1993Date of Patent: April 16, 1996Assignee: Symbiosis CorporationInventors: Charles R.

Patent number: 5452335Abstract: An apparatus for counting the number of times a temperature cycle occurs includes an indicator having sequential indicia and a temperature responsive member for indicating a next one of the indicia. Mechanical, fluid mechanical and electronic versions of the invention are disclosed. In the mechanical version, the indicator can be a ratchet member having teeth, a pawl and a display surface containing indicia. A temperature responsive element such as a bimetallic member engages the teeth of the ratchet and advances the ratchet each time the apparatus is subjected to a preset temperature cycle. A housing with a window masks the display to indicate one of the indicia as advanced by the temperature responsive element. Preferred embodiments of the mechanical version include a ring-like ratchet member with interior teeth and an exterior display surface.Type: GrantFiled: December 31, 1992Date of Patent: September 19, 1995Assignee: Symbiosis CorporationInventors: Charles R.

Patent number: 5429596Abstract: An endoscopic electrosurgical suction-irrigation instrument with insertable probes and attachments is disclosed. The instrument has a fluid chamber sealed at its proximal end with a slit valve for receiving the probes and connected at its distal end to a cannula through which the inserted probes extend. The fluid chamber is selectively provided with suction and/or irrigation and includes an electrical contact for supplying voltage to an inserted electrosurgical probe. Depending on the probe configuration suction and/or irrigation is provided in an annular space between the probe and the cannula or through the probe. Valves, connectors and switches for use with the instrument are also disclosed.Type: GrantFiled: May 23, 1994Date of Patent: July 4, 1995Assignee: Symbiosis CorporationInventors: Juan J.
