First Claim
1. An endoscopic bipolar forceps, comprising:
- an elongated shaft having opposing jaw members at a distal end thereof, the jaw members being movable 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;
a source of electrical energy connected to each jaw member such that the jaw members are capable of conducting energy through tissue held therebetween to effect a seal; and
a generally tube-like cutter slidably engaged about said elongated shaft which is selectively movable about said elongated shaft to engage and cut tissue on at least one side of the jaw members while the tissue is engaged between jaw members.

Abstract
An endoscopic bipolar forceps includes an elongated shaft having opposing jaw members at a distal end thereof. The jaw members are movable 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 forceps also includes a source of electrical energy connected to each jaw member such that the jaw members are capable of conducting energy through tissue held therebetween to effect a seal. A generally tube-like cutter is included which is slidably engaged about the elongated shaft and which is selectively movable about the elongated shaft to engage and cut tissue on at least one side of the jaw members while the tissue is engaged between jaw members.

15. An endoscopic bipolar forceps, comprising:
-
an elongated shaft having opposing jaw members at a distal end thereof, one of the jaw members being movable relative to the other jaw member 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;
an electrically conductive outer sleeve which at least partially surrounds said shaft, said outer sleeve mechanically cooperating with said movable jaw member to pivot said jaw member from the first to second positions; and
means for selectively moving said outer sleeve to electrosurgically energize and pivot said jaw members.
