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.

Claims

1. A medical device comprising:

an elongate member having a proximal end, a distal end, and a lumen extending therebetween; and

an end-effector disposed at the distal end of the elongate member, the end-effector including 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,

wherein the tissue-contacting surface includes a channel oriented substantially parallel to a longitudinal axis of the medical device.

2. The device of claim 1, wherein only one of the plurality of arms is configured to move.

3. The device of claim 1, wherein the entire tissue-contacting surface includes ridges.

4. The device of claim 1, wherein a second portion of the tissue-contacting-surface includes a mating surface having one or more teeth or ridges.

5. The device of claim 1, wherein the channel extends in a direction that is substantially parallel to a longitudinal axis of the elongate member.

6. The device of claim 1, further comprising a cutting element configured to be advanced through the channel.

7. The device of claim 6, wherein the cutting element includes a cautery device.

8. The device of claim 1, further comprising a locking device for selectively fixing a position of at least one of the plurality of arms.

10. A medical device comprising:

an elongated member having a proximal end, a distal end, and a lumen extending therebetween;

a control member extending within the lumen of the elongated member, the control member having a distal end and a proximal end;

an end-effector disposed at a distal end of the control member, the end-effector including at least two arms connected at their proximal ends to form a jaw-like structure, wherein each of the arms includes a tissue-contacting-surface; and

a plurality of retractable projections disposed on at least one of the tissue-contacting-surfaces.

9. The device of claim 13, a distalmost surface of at least one of the plurality of arms includes an atraumatic surface.

11. The device of claim 10, wherein only one of the plurality of arms is configured to move.

12. The device of claim 10, further comprising a locking device for selectively fixing a position of at least one of the plurality of arms.

13. The device of claim 10, wherein the projections are configured to selectively retract into respective openings on the at least one of the tissue-contacting surfaces.

14. The device of claim 10, wherein both tissue-contacting-surfaces include a plurality of retractable projections.

15. The device of claim 10, wherein at least one of the arms further includes a substantially flat surface disposed proximate the tissue-contacting surface.

16. A medical device comprising:

an elongated member having a proximal and a distal end and a lumen extending therebetween;

a control member extending within the lumen of the elongated member, the control member having a distal end and a proximal end;

an end-effector disposed at a distal end of the control member, the end-effector including at least two arms connected at its proximal end to form a jaw-like structure, wherein each of the arms includes a substantially flat inner surface disposed adjacent to a plurality of ridges.

17. The device of claim 16, wherein only one of the plurality of arms is configured to move.

18. The device of claim 16, further comprising a locking device for selectively fixing a position of at least one of the plurality of arms.

19. The device of claim 16, wherein at least one of the plurality of ridges further includes at least one selectively deployable projection.

20. The device of claim 16, wherein the substantially flat inner surface includes a plurality of substantially flat inner surfaces.
