Appl. No.:

12/543973

Inventors:

Philip M. Tetzlaff - Austin TX, US
Carolyn Mihaichuk - Longmont CO, US

Assignee:

Covidien AG - Neuhausen am Rheinfall

International Classification:

A61B 18/14

US Classification:

606 51, 606 52

Abstract:

A bipolar electrosurgical instrument for clamping, grasping, manipulating, and sealing tissue includes first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof. The handle being operable to effect movement of the jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. The bipolar instrument is connectable to a source of electrical energy having a first electrical potential connected to one of the jaw members and a second electrical potential connected to the other of the jaw members such that the jaw members are capable of selectively conducting energy though tissue held therebetween to effect a seal. Both the first and second electrical potentials are transmitted to the jaw members through the first shaft.
