1. An end effector comprising:
- a first jaw member comprising a first positively-angled tissue-contacting surface; and
a second jaw member comprising a second positively-angled tissue-contacting surface;
wherein the first jaw member is movable relative to the second jaw member between an open position and a closed position;
wherein at least one of the first jaw member and the second jaw member comprises at least one active electrode disposed on the jaw member adjacent to the positively-angled tissue-contacting surface; and
wherein the at least one active electrode is configured to deliver RF energy to tissue located between the first jaw member and the second jaw member when in the closed position.

Abstract
Surgical end effectors are disclosed having angled tissue-contacting surfaces. The end effectors may have a first jaw member that is movable relative to a second jaw member between an open position and a closed position. The first jaw member may have a first positively-angled tissue-contacting surface. The second jaw member may have a second positively-angled tissue-contacting surface. At least one of the jaw members may have at least one active electrode configured to deliver RF energy to tissue located between the first jaw member and the second jaw member when in the closed position.

11. An end effector comprising:
-
a first jaw member comprising a first positively-angled tissue-contacting surface and a first negatively-angled tissue-contacting surface; and a second jaw member comprising a second positively-angled tissue-contacting surface and a second-negatively angled tissue-contacting surface; wherein the first jaw member is movable relative to the second jaw member between an open position and a closed position; and wherein the first positively-angled tissue-contacting surface opposes the second negatively-angled tissue-contacting surface when the first and second jaw members are in the closed position, and wherein the first negatively-angled tissue-contacting surface opposes the second positively-angled tissue-contacting surface when the first and second jaw members are in the closed position. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. An end effector comprising:
-
a first jaw member comprising; a first proximal tissue-contacting portion; a first distal textured portion adjacent to the first proximal tissue-contacting portion; a first positively-angled tissue-contacting surface disposed along the first proximal tissue-contacting portion; and at least one first electrode located in the first proximal tissue-contacting portion adjacent to the first positively-angled tissue-contacting surface; and a second jaw member comprising; a second proximal tissue-contacting portion; a second distal textured portion adjacent to the second proximal tissue-contacting portion; a second positively-angled tissue-contacting surface disposed along the second proximal tissue-contacting portion; and at least one second electrode located in the second proximal tissue-contacting portion adjacent to the second positively-angled tissue-contacting surface; wherein the first jaw member is movable relative to the second jaw member between an open position and a closed position; and wherein the at least one first electrode and second electrode are in a bipolar configuration to deliver RF energy to tissue located between the first jaw member and the second jaw member when in the closed position.
