Abstract

A surgical clip may include: a first leg member having an inner surface, an outer surface, and first and second side surfaces, the inner surface of the first leg member having a concave curvature; a second leg member having an inner surface, an outer surface, and first and second side surfaces, the inner surface of the second leg member having a convex curvature; at least one first tooth extending from a first lateral side of the inner surface of the second leg member; and a first channel defined between the first side surface and the inner surface of the first leg member. The first and second leg members may be configured to move between an open configuration and a closed configuration, and in the closed configuration, the at least one first tooth is received in the first channel.

Claims (25)

1 . A surgical clip comprising:

a first leg member having an inner surface, an outer surface, a first side surface, a second side surface, and a first longitudinal channel; and

a second leg member having an inner surface, an outer surface, a first side surface, a second side surface, and at least one first tooth extending from the first side surface of the second leg member;

wherein the first and second leg members are configured to move between an open configuration and a closed configuration;

wherein the at least one first tooth is configured to extend past the inner surface of the first leg member when the first and second leg members are in the closed configuration; and

wherein the first longitudinal channel is configured to receive the at least one first tooth when the first and second leg members are in a closed configuration.

2 . The surgical clip of claim 1 , wherein the first leg member further comprises a second longitudinal channel, the inner surface of the first leg member being disposed between the first and second longitudinal channels; and the second leg member further comprises at least one second tooth extending from the second side surface of the second leg member; wherein the at least one second tooth is configured to extend past the inner surface of the first leg member when the first and second leg members are in the closed configuration, and wherein the second longitudinal channel is configured to receive the at least one second tooth when the first and second leg members are in the closed configuration.

3 . The surgical clip of claim 2 , wherein the at least one first tooth is configured to extend along the first side surface of the first leg member to overlap an inner portion of the first leg member in the closed configuration, and the at least one second tooth is configured to extend along the second side surface of the first leg member to overlap the inner portion of the first leg member in the closed configuration.

4 . The surgical clip of claim 2 , wherein the inner surface of the second leg member is disposed between the at least one first tooth and the at least one second tooth.

5 . The surgical clip of claim 2 , wherein the inner surface of the first leg member and the inner surface of the second leg member are configured to approximate or contact each other with minimal or no gap in the closed configuration.

6 . The surgical clip of claim 2 , wherein the inner surface of the first leg member and the inner surface of the second leg member are substantially smooth.

7 . The surgical clip of claim 2 , wherein the first side surface of the first leg member defines the first longitudinal channel, and the second side surface of the first leg member defines the second longitudinal channel.

8 . The surgical clip claim 2 , wherein the first longitudinal channel is recessed from and adjacent to the inner surface of the first leg member, and the second longitudinal channel is recessed from and adjacent to the inner surface of the first leg member.

9 . The surgical clip of claim 2 , wherein the first and second longitudinal channels are on opposed lateral sides of the first leg member.

10 . The surgical clip of claim 2 , wherein the first and second longitudinal channels are distinct and not connected with each other.

11 . The surgical clip of claim 2 , wherein the at least one first tooth and/or the at least one second tooth is substantially atraumatic.

12 . The surgical clip of claim 2 , wherein the at least one first tooth has a substantially flat inner surface that is substantially parallel to the inner surface of the second leg member, and/or the at least one second tooth has a substantially flat inner surface that is substantially parallel to the inner surface of the second leg member.

13 . The surgical clip of claim 2 , wherein the at least one first tooth and/or the at least one second tooth is substantially rigid.

14 . The surgical clip of claim 2 , wherein the at least one first tooth extends substantially perpendicular to the inner surface of the first leg member in the closed configuration, and the at least one second tooth extends substantially perpendicular to the inner surface of the first leg member in the closed configuration.

15 . The surgical clip of claim 2 , wherein the at least one first tooth extends substantially parallel to the first side surface of the first leg member in the closed configuration, and the at least one second tooth extends substantially parallel to the second side surface of the first leg member in the closed configuration.

16 . The surgical clip of claim 1 , wherein the inner surface of the first leg member has a first curvature, and the inner surface of the second leg member has a second curvature, the first and second curvatures being complementary to each other.

17 . The surgical clip of claim 1 , wherein the inner surface of the first leg member has a concave curvature, and the inner surface of the second leg member has a convex curvature.

18 . The surgical clip of claim 1 , further comprising an integrally formed polymeric body.

19 . The surgical clip of claim 1 , further comprising a hook portion at a distal end of the first leg member, and a tip member at a distal end of the second leg member, wherein the hook portion is configured to engage the tip member to secure the surgical clip in a latched configuration.
