Abstract

A medical device including an elongate member having a proximal end, a distal end, and a lumen extending therebetween. The medical device may further include an end-effector disposed at the distal end of the elongate member. The end-effector may include a plurality of arms pivotally connected to one another, wherein each arm includes a tissue-contacting surface, a first portion of the tissue-contacting surface including a plurality of ridges configured to grasp tissue. Further, the tissue-contacting surface may include a channel oriented substantially parallel to a longitudinal axis of the medical device.

First claim

What is claimed is:

1. A medical instrument comprising:
a member having a proximal end and a distal end;
an end effector having a first arm and a second arm, wherein the first arm and the second arm are coupled to the distal end of the member, and the first arm and the second arm are moveable relative to one another;
a first plurality of ridges and a second plurality of ridges, wherein the first plurality of ridges and the second plurality of ridges extend along the first arm
a first unridged portion on the first arm, facing the second arm, proximal to the first plurality of ridges of the first arm, and distal to the second plurality of ridges of the first arm, wherein the first unridged portion extends along an entire lateral width of the first arm, wherein a lateral direction is perpendicular to a longitudinal axis of the first arm, and wherein the longitudinal axis extends from a proximal end of the first arm to a distal end of the first arm;
a second unridged portion on the first arm, facing the second arm, proximal to the second plurality of ridges, wherein the second unridged portion extends along the entire lateral width of the first arm; and
a third plurality of ridges, wherein the third plurality of ridges extend along the first arm, wherein axes extending along apexes of the third plurality of ridges of the first arm intersect one another.

2. The medical instrument of claim 1 , further comprising: one or more staples positioned along at least a portion of the second arm, opposite the first unridged portion of the first arm or the second unridged portion of the first arm, wherein the first unridged portion of the first arm or the second unridged portion of the first arm includes an anvil for striking the one or more staples.

3. The medical instrument of claim 1 , wherein at least one of the first arm or the second arm defines an aperture, extending through a thickness of at least one of the first arm or the second arm.

4. The medical instrument of claim 3 , wherein the aperture is a first aperture, wherein the first arm defines the first aperture extending through a thickness of the first arm, and wherein the second arm defines a second aperture extending through a thickness of the second arm.

5. The medical instrument of claim 4 , wherein the first aperture is longitudinally aligned with the second aperture.

6. The medical instrument of claim 1 , wherein at least some of the first plurality of ridges of the first arm and at least some of the second plurality of ridges of the first arm extend along the entire lateral width of the first arm.

7. The medical instrument of claim 1 , wherein the second arm comprises:
a fourth plurality of ridges;
a fifth plurality of ridges;
a third unridged portion, facing the first arm, proximal to the fourth plurality of ridges, and distal to the fifth plurality of ridges, wherein the third unridged portion extends along an entire lateral width of the second arm, wherein a lateral direction is perpendicular to a longitudinal axis of the second arm, and wherein the longitudinal axis extends from a proximal end of the second arm to a distal end of the second arm; and
a fourth unridged portion, facing the first arm, proximal to the fifth plurality of ridges, wherein the fourth unridged portion extends along the entire lateral width of the second arm.

8. The medical instrument of claim 1 , wherein each ridge of the first plurality of ridges defines an apex and a trough, wherein a height of the apex is greater than a height of the trough, wherein a height direction extends perpendicularly to the longitudinal axis of the first arm and perpendicularly to the lateral direction, and wherein a height of the trough of each ridge of the first plurality of ridges is the same as a height of the first unridged portion;
wherein each ridge of the second plurality of ridges defines an apex and a trough, wherein a height of the apex is greater than a height of the trough, and wherein a height of the trough of each ridge of the second plurality of ridges is the same as a height of the second unridged portion.
