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 method of manipulating tissue, the method comprising:
inserting a sheath into a body of a patient;
inserting an instrument into the sheath, wherein the instrument comprises:
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 moveably coupled to the distal end of the member;
a plurality of ridges extending along the first arm and the second arm;
an unridged portion on the first arm, facing the second arm, and proximal to at least some of the plurality of ridges of the first arm, wherein the unridged portion extends along an entire lateral width of the first arm, wherein a lateral direction is perpendicular to a longitudinal axis of the unridged portion, and wherein the longitudinal axis extends from a proximal end of the unridged portion to a distal end of the unridged portion;
one or more staples positioned along at least a portion of the second arm, opposite the unridged portion of the first arm, wherein the unridged portion of the first arm is an anvil for striking the one or more staples; and
a channel extending from a proximal region to a distal region of at least one of the first arm or the second arm;

visualizing a surgical field within the body of the patient;
manipulating tissue using the end effector of the instrument, wherein a tool is at least partially received within the channel and is moveable along at least a portion of the channel; and
stapling the tissue using the end effector of the instrument.

2. The method of claim 1 , wherein the tool includes a cutting tool, and manipulating the tissue includes at least one of cutting the tissue or cauterizing the tissue.

3. The method of claim 1 , wherein the tool includes an electrode, wherein inner surfaces of the first and second arms are formed of non-conductive material, and wherein manipulating the tissue includes cauterizing the tissue.

4. The method of claim 1 , wherein a distal end of the end effector includes at least one of a spear tip, a curved beak, or a flattened edge, and manipulating the tissue includes scraping the tissue.

5. The method of claim 1 , wherein the tool includes a needle, and wherein manipulating the tissue includes at least one of cutting the tissue or cauterizing the tissue.

6. The method of claim 1 , wherein the first arm and the second arm are moveably coupled to the distal end of the member, wherein the first arm includes a first proximal portion having a first longitudinal axis and a first distal portion that extends radially away from the first proximal portion, wherein the second arm includes a second proximal portion having a second longitudinal axis and a second distal portion that extends radially away from the second proximal portion, wherein the first distal portion extends away from the second distal portion, and wherein the second distal portion extends toward the first distal portion.

7. The method of claim 1 , wherein inner surfaces of the first and second arms are detachable from remainders of the first and second arms, respectively.

8. The method of claim 1 , wherein a distalmost end of at least one of the first arm or the second arm includes a flat edge.

9. The method of claim 1 , wherein axes of the plurality of ridges of the second arm intersect one another.

10. The method of claim 1 , wherein one of the plurality of ridges is larger than another of the plurality of ridges.

11. The method of claim 1 , wherein at least one of the first arm or the second arm defines a curved aperture, separate from the channel, extending through a thickness of the at least one of the first arm or the second arm.

12. The method of claim 11 , wherein the aperture is a first aperture, wherein the first arm defines the first aperture, and wherein the second arm defines a second aperture extending through a thickness of the second arm.

13. The method of claim 12 , wherein the first aperture is longitudinally aligned with the second aperture.

14. The method of claim 1 , wherein the end effector includes a locking mechanism configured to fix the first arm relative to the second arm.

15. The method of claim 1 , wherein the first arm includes a proximal portion having a first longitudinal axis and a distal portion that extends radially outwardly relative to the first longitudinal axis.

16. The method of claim 15 , wherein the second arm includes a proximal portion having a second longitudinal axis and a distal portion that extends radially inward, past the longitudinal axis of the first arm.

17. The method of claim 15 , wherein the one or more staples are positioned opposite only the unridged portion of the first arm.

18. The method of claim 15 , wherein the at least some of the plurality of ridges of the first arm extend along an entire lateral width of the first arm.

19. The method of claim 15 , wherein at least some of the plurality ridges extend laterally from a first edge of the first arm to the channel and from a second edge of the first arm to the channel.

20. The method of claim 15 , wherein the first arm includes only one unridged portion.
