  • Patent number: 6395012
    Abstract: An apparatus and method delivers an expandable body member into a uterine cavity of a uterus through a cervical opening and deploys the expandable body member in the uterine cavity. The expandable body member in a compressed state is inserted into the uterine cavity. A fluid is provided to the uterine cavity at a pressure sufficient to inflate the uterine cavity. The expandable body member expands from the compressed state to the expanded state. After expansion of the expandable body member and inflation of the uterine cavity, the fluid pressure is relieved thereby collapsing the uterine cavity about the expandable body member in the expanded state such that an endometrial layer of the uterus and a surface of the expandable body member substantially contact each other in a facially opposing relationship maximizing contact therebetween.

  • Patent number: 5404870
    Abstract: A transanal inserter is disclosed which facilitates the atraumatic insertion of intra-anal surgical devices through the anus. The inserter has a tubular portion, a prolate distal end and a proximal end having a flange associated therewith. The prolate end is formed from a plurality of petal-shaped segments which deflect outward as an intra-anal surgical device is urged therethrough, into the colon or intestine. The flange formed at the proximal end of the inserter retains the inserter in place and prevents over insertion of the inserter beyond the anus. The inserter can be fabricated in varying lengths to accommodate surgical requirements. The inserter is fabricated from a plastic material with sufficient pliability to provide for deflection of the segments, while maintaining sufficient rigidity to prevent collapse of the inserter during insertion and use.

  • Patent number: 5222963
    Abstract: A mechanism which is capable of anastomosis of two lumens by an absorbable fastener. The fastener is made from two washer-like plates. One such plate has holes to receive latching prongs protruding from the other plate. Fastening is done through a single linear motion that causes the prongs to pierce the tissue, latches the prongs into a receiver and causes a knife blade to cut through excess fastener material and tissue. The ease of removal, by pulling the mechanism thorugh the formed anastomosis, is greatly enhanced. The system can be used such that the plates can be placed in any configuration to properly anastomose tissue.

  • Patent number: 4747531
    Abstract: An anvil and driver assembly for a surgical skin stapling instrument producing formed and implanted skin staples of more consistant and perfect configuration. The anvil provides an anvil surface which supports the crown of the staple during the forming operation. The driver has an inverted U-shaped notch formed therein which defines parallel side edges to bend the staple legs about the anvil and a transverse edge joining the side edges and adapted to contact the crown of the staple near the end of the forming operation. In the anvil and driver assembly of the present invention, the clearance between the parallel bending edges of the driver and the adjacent anvil edges is greater than the transverse dimension of the staple wire. The anvil surface of the anvil is concave and the crown contacting edge of the driver is so configured as to impart a temporary bow in the staple crown near the bottom of the driver stroke, which bow is of such dimension as to preclude plastic deformation of the crown.
