  • Patent number: 10327758
    Abstract: A multiple-firing crimp device comprises crimps, a shaft, a crimp movement assembly, and a snare. Each crimp has an internal hollow. The shaft has a distal crimping location, an exterior surface, and an interior with the clips stacked therein, the crimps moving therein along a longitudinal axis. The shaft defines a lateral opening proximal to the crimping location and communicates the interior to the environment outside the exterior surface. The crimp movement assembly within the shaft delivers the first crimp to the distal crimping location by moving the first crimp longitudinally from a first proximal position into the distal crimping location and returning to a second proximal position without the first crimp. The snare pulls at least one cord from distal of the first crimp through the first crimp and through a portion of the shaft and out the side of the shaft through the lateral opening.

  • Publication number: 20160166248
    Abstract: A multiple-fire securing device includes a hollow outer shaft, a reloader, a reloader movement assembly, a rail, and securing structures each defining an inner securing orifice. The reloader longitudinally moves within the outer shaft and has a distal end shaped to temporarily contact one of the securing structures. The rail is disposed within the reloader and has an installing location. The securing structures are disposed on the rail. The reloader movement assembly moves the reloader longitudinally in a distal direction to deliver a first securing structure to the installing location from a first proximal position and moves the reloader proximally away from the installing location without the first securing structure to a position in which the distal end of the reloader temporarily contacts a second one of the securing structures. The second and successive securing structures are moved one at a time to the installing location.

  • Patent number: 8006889
    Abstract: 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.

  • Patent number: 7896215
    Abstract: 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.
