Abstract

The present disclosure relates to compression clips, and more specifically, to compression clips delivered to a target site through an endoscope for use in tissue resection, for example, within the gastrointestinal tract. In examples, clips are configured to be actuatable in response to a compressive force to transition between an open configuration and a closed configuration. In an embodiment, a tissue clipping device may include a first member with a plurality of arms. Each of the arms may extend from a first end to a second end, and the first end of each arm may be received within the first member. The arms may be movable between the open configuration and the closed configuration. A second member may be slidably disposed with respect to the first member.

Claims (30)

1. A tissue clipping device, comprising:

a proximal member;

a distal member movable with respect to the proximal member; and

a pair of arms, each of the arms extending from a proximal end to a distal end, the proximal end of each of the arms being operatively associated with at least one of the proximal member or the distal member;

wherein the proximal member and the distal member have surfaces extending circumferentially therearound and configured to displace a distal end of the proximal member and proximal end of the distal member longitudinally apart from each other in response to an application of a radially-inwardly directed force to the surfaces to cause the arms to move between an open configuration, in which the arms are separated from each other to receive tissue therebetween, and a closed configuration in which the arms grip tissue between each other.

2. The tissue clipping device of claim 1 , wherein the surfaces of the distal member and the proximal member are configured to be graspable by a gripper tool regardless of the orientation of the gripper tool relative to the surfaces to move the proximal member and the distal member apart from each other upon being grasped by the gripper tool.

3. The device of claim 1 , wherein the surfaces of the proximal member and the distal member include angled surfaces configured to displace the distal end of the proximal member and the proximal end of the distal member to be spaced apart from each other longitudinally in response to application of the radially-inwardly directed force to the angled-surfaces.

4. The tissue clipping device of claim 1 , further comprising a grasper having a first end engaged between the arms and a second end comprising jaws configured to engage tissue.

5. The tissue clipping device of claim 4 , wherein the grasper comprises first and second grasper arms in a crossing configuration in which the second ends of the grasper arms move away from each other when the first ends of the grasper arms move closer together.

6. The tissue clipping device of claim 1 , wherein the arms are biased to the closed configuration.

7. The tissue clipping device of claim 1 , wherein the arms are received within the distal member.

8. The tissue clipping device of claim 1 , further comprising a cam movable with one of the proximal member or the distal member to cause the arms to move between the closed configuration and the open configuration.

9. The tissue clipping device of claim 1 , wherein the arms are mechanically constrained with respect to one of the proximal member or the distal member such that as the proximal member is longitudinally displaced with respect to the distal member, the arms are displaced.

10. The tissue clipping device of claim 1 , wherein one of the proximal member or the distal member is disposed about the arms, and the proximal member is slidable with respect to the distal member to cause the arms to move between the open configuration and the closed configuration.

11. The tissue clipping device of claim 1 , wherein the surfaces include surfaces inclined towards each other and configured to displace the proximal member and the distal member apart from each other longitudinally in response to application of radially-inwardly directed to force to the inclined surfaces.

12. A tissue clipping device, comprising:

a grasping portion comprising a first member and a second member movable with respect to each other along the longitudinal axis of the tissue clipping device; and

a pair of arms, each of the arms extending from a first end to a second end;

wherein longitudinal ends of the first member and the second member are configured to be moved apart from each other in response to application of a radially-inwardly directed force to outer surfaces of the first member and the second member sufficiently to transition the arms between a closed configuration, with the arms separated from one another to receive tissue therebetween, and an open configuration in which the arms grip tissue therebetween.

13. The tissue clipping device of claim 12 , wherein the first member and the second member have outer surfaces configured to be graspable by a gripper tool regardless of the orientation of the gripper tool relative to the surfaces to displace the first member and the second member longitudinally apart from each other upon being grasped by the gripper tool to move the arms between the closed configuration and the open configuration.

14. The tissue clipping device of claim 12 , wherein the arms are biased to the closed configuration.

15. The tissue clipping device of claim 12 , wherein the first member and the second member include adjacent angled surfaces configured to displace the first member and the second member apart from each other in response to application of the radially-inwardly directed force to the angled surfaces.

16. The tissue clipping device of claim 12 , wherein the arms are formed of a single body bent at a medial portion, the medial portion forming the first ends of the arms.

17. The tissue clipping device of claim 12 , further comprising a grasper disposed between the second ends of the arms.

18. A tissue clipping device, comprising:

a grasping portion comprising a first member and a second member movable with respect to each other along the longitudinal axis of the tissue clipping device; and

a pair of arms, each of the arms extending from a first end to a second end;

wherein the first member and the second member are configured to be displaced relative to each other in response to application of a radially-inwardly directed force to cooperating surfaces at ends of the first member and the second member to transition the arms between a closed configuration, in which the arms grip tissue between each other, and an open configuration, in which the arms are separated from each other to receive tissue therebetween.

19. The tissue clipping device of claim 18 , wherein the cooperating surfaces of the first member and the second member are configured to be graspable by a gripper tool regardless of the orientation of the gripper tool relative to the cooperating surfaces to move the first member and the second member apart from each other upon being grasped by the gripper tool.

20. The tissue clipping device of claim 18 , wherein the cooperating surfaces are inclined surfaces at adjacent ends of the first member and the second member.
