Title: Electrosurgical stapling apparatus
Inventor: HEINRICH RUSSELL
IPC: A61B18/14
Filed: 2003-05-09
Granted: 2011-01-04
Abstract: An electrosurgical stapling apparatus is provided which uses thermogenic energy as well as surgical fasteners or staples for strengthening tissue, providing hemostasis, tissue joining or welding. The thermogenic energy also strengthens tissue in proximity to a staple line and knife cut line and provides hemostasis along the staple and cut lines formed by the staples and a knife blade during surgical stapling. The use thermogenic energy provides short-term hemostasis and sealing, and reduces or prevents staple line and cut line bleeding, while the stapling features provide short and long-term tissue strength and hemostasis. The stapling apparatus further substantially reduces or prevents knife cut line bleeding by energizing a knife blade for cauterizing tissue while it is being cut. In one embodiment, energy is applied to the anvil to energize the staples as they make contact with the anvil.

Abstract: A tethering system having an elongate flexible element, with a length, and an anchoring system. The anchoring system has a block defining first and second surfaces. The anchoring system further includes (a) a first anchoring assembly for bearing a first portion of the elongate flexible element against the first surface with the first anchoring assembly in a first state to maintain the first portion of the elongate flexible element substantially fixed against movement relative to the first surface, and (b) a second anchoring assembly for bearing a second portion of the elongate flexible element against the second surface with the second anchoring assembly in a first state to maintain the second portion of the elongate flexible element substantially fixed against movement relative to the second surface. The first anchoring assembly is changeable selectively between its first state and a second state wherein the first portion of the elongate flexible element can move relative to the first surface. The second anchoring assembly is changeable selectively between its first state and a second state wherein the second portion of the elongate flexible element can move relative to the second surface. The elongate flexible element is formable into a loop with a diameter between the first and second portions. The loop is maintainable in a selected diameter with the first and second anchoring assemblies in their first states. The diameter of the loop is variable by placing the first anchoring assembly in its second state and moving the first portion of the elongate flexible element relative to the first surface to produce a changed diameter for the loop. The first anchoring assembly is changeable from its second state into its first state to thereby maintain the changed diameter for the loop.
