Abstract

Medical devices and methods of using medical devices are disclosed. An example tissue retraction device includes a first tissue engagement member coupled to an elastic member by a coupling assembly. The coupling assembly including a first coupler body having a first end region and a first compression member. Further, the first end region of the first coupler body is configured to extend into a portion of a lumen of the elastic member and the compression member is designed to compress the elastic member onto the first coupler body such that the elastic member is fixedly engaged with the coupler body.

Claims (54)

1. A tissue retraction device extending along a longitudinal axis and comprising:

a first tissue engagement member;

an elastic member; and

a coupling assembly comprising a coupler body and a connection member;

wherein:

the first tissue engagement member is coupled to the elastic member to be rotatable about the longitudinal axis of the tissue retraction device;

the elastic member is coupled to the coupler body; and

the tissue engagement member is coupled to the connection member.

2. The tissue retraction device of claim 1 , wherein the first tissue engagement member is rotatable about the longitudinal axis of the tissue retraction device via the coupling assembly.

3. The tissue retraction device of claim 1 , wherein

the connection member and the coupler body are rotatable with respect to each other.

4. The tissue retraction device of claim 1 , wherein:

the connection member comprises a post member and an attachment member;

the post member extends through the coupler body and is rotatable about a longitudinal axis of the post member and the coupler body; and

the attachment member is coupled to the first tissue engagement member.

5. The tissue retraction device of claim 1 , wherein the connection member and the coupler body are rotatable with respect to each other about a longitudinal axis of the coupling assembly.

6. The tissue retraction device of claim 1 , wherein:

the first tissue engagement member has a first end movable between a first configuration and a second configuration, and a second end extending in a direction away from the first end; and

the elastic member is rotatably coupled to the second end of the first tissue engagement member.

7. The tissue retraction device of claim 1 , wherein:

the first tissue engagement member has a first end and a second end;

the elastic member is coupled to the second end of the first tissue engagement member and extends longitudinally therefrom; and

the elastic member and the first tissue engagement member are rotatable about a longitudinally extending post coupled between the elastic member and the first tissue engagement member.

8. A tissue retraction device extending along a longitudinal axis and comprising:

a first tissue engagement member having a first end configured to engage tissue, and a second end;

a coupling assembly; and

the attachment member is coupled to the first tissue engagement member.

10. The tissue retraction device of claim 8 , wherein:

the first tissue engagement member includes first and second jaw members biased by a spring; and

the connection member is coupled to the spring.

11. The tissue retraction device of claim 8 , wherein the coupler body and the connection member are rotatable with respect to each other.

12. The tissue retraction device of claim 11 , wherein the coupler body is rotatable about a longitudinal axis of the connection member.

13. The tissue retraction device of claim 8 , wherein:

the first end of the first tissue engagement member is movable between a first configuration and a second configuration; and

the second end of the first tissue engagement member extends longitudinally away from the first end of the first tissue engagement member.

14. The tissue retraction device of claim 13 , wherein the tether and the first tissue engagement member are longitudinally rotatable with respect to each other about a longitudinally extending post coupled between the tether and the first tissue engagement member.

15. The tissue retraction device of claim 8 , wherein the tether and the first tissue engagement member are longitudinally rotatable with respect to each other about a longitudinally extending post coupled between the tether and the first tissue engagement member.

16. The tissue retraction device of claim 8 , wherein the tether is elastic.

17. A tissue retraction device comprising:

a first tissue engagement member having a first end with first and second members extending therefrom and movable with respect to each other to move the first tissue engagement member between a first configuration and a second configuration, and a second end extending in a direction away from the first end;

an elastic member coupled to the second end of the first tissue engagement member; and

a coupling assembly comprising a connection member and a coupler body, wherein the elastic member is coupled to the coupler body and the connection member is coupled to the first tissue engagement member.

18. The tissue retraction device of claim 17 , wherein the coupler body and the connection member are rotatable with respect to each other about a longitudinal axis of the coupling assembly.

19. The tissue retraction device of claim 17 , wherein the coupler body and the connection member are rotatable with respect to each other.

20. The tissue retraction device of claim 17 , wherein the first tissue engagement member and the elastic member are longitudinally rotatable with respect to each other.
