Abstract

Medical devices and methods for using medical devices are disclosed. An example medical device may include a tubular member having a lumen defined therein and a proximal end. A shaft may extend through the lumen. The shaft may have a distal end and a proximal end. An end effector may be attached to the distal end of the shaft. A handle may be coupled to the proximal end of the tubular member. The handle may include a base, a first hub member attached to the base, a second hub member coupled to the first hub member, and a cap attached to the second hub member.

First claim

What is claimed is:

1 . A medical device, comprising:
a tubular member having a lumen defined therein and a proximal end; a shaft extending through the lumen, the shaft having a distal end and a proximal end; an end effector associated with the distal end of the shaft; a handle coupled to the proximal end of the tubular member; and wherein the handle includes a base, a first hub member coupled to the base, a second hub member coupled to the first hub member, and a cap coupled to the second hub member.

2 . The medical device of claim 1 , wherein the second hub member comprises a first enclosure member and a second enclosure member attached to the first enclosure member.

3 . The medical device of claim 1 , wherein the second hub member has a chamber formed therein.

4 . The medical device of claim 3 , wherein the chamber is configured to receive a projection formed on the first hub member.

5 . The medical device of claim 4 , wherein the second hub member is configured to rotate relative to the first hub member about the projection.

6 . The medical device of claim 1 , wherein the second hub member is coupled to the cap with a threaded connection.

7 . The medical device of claim 1 , wherein the second hub member is configured to compress onto the first hub member.

8 . The medical device of claim 1 , wherein the second hub member is coupled to the cap with a snap fit connection.

9 . The medical device of claim 1 , wherein the first hub member is coupled to the base with a threaded connection.

10 . The medical device of claim 1 , wherein the shaft extends through the base, wherein the base has slot formed therein, and wherein a gripping member is disposed along the base and has a projection that extends through the slot and is attached to the shaft.

11 . The medical device of claim 10 , wherein the gripping member is slidable along the base.

12 . The medical device of claim 1 , further comprising a rotation member disposed at a proximal end of the base.

13 . The medical device of claim 1 , wherein the first hub member is coupled to an outer surface of the base.

14 . The medical device of claim 13 , wherein the second hub member is coupled to the outer surface of the first hub member.

15 . The medical device of claim 14 , wherein the cap is coupled to the outer surface of the second hub member.

16 . A medical device comprising:
a tubular member having a lumen defined therein and a proximal end; a shaft extending through the lumen, the shaft having a distal end and a proximal end; an end effector associated with the distal end of the shaft; and a handle assembly coupled to the proximal end of the tubular member, the handle assembly including a rotation assembly, the rotation assembly consisting of a base, a first hub member coupled to an outer surface of the base, a second hub member coupled to the first hub member and rotatable relative to the first hub member, and a cap threadably coupled to the second hub member.

17 . The medical device of claim 16 , wherein the second hub member has a chamber formed therein and wherein the chamber is configured to receive a projection formed on the first hub member.

18 . The medical device of claim 17 , wherein the second hub member is configured to rotate relative to the first hub member about the projection.

19 . The medical device of claim 16 , wherein the shaft extends through the base, wherein the base has slot formed therein, and wherein a gripping member is disposed along the base and has a projection that extends through the slot and is attached to the shaft.

20 . A medical device comprising:
a tubular member having a lumen defined therein and a proximal end; a shaft extending through the lumen, the shaft having a distal end and a proximal end; an end effector associated with the distal end of the shaft; and a handle coupled to the proximal end of the tubular member, the handle including a rotation assembly, the rotation assembly including a monolithic base and first hub member, a second hub member coupled to the monolithic base and first hub member and rotatable relative to the monolithic base and the first hub member, and a cap threadably coupled to the second hub member.
