Abstract

A clip for engaging tissue includes a generally annular-shaped body defining a plane and disposed about a central axis extending normal to the plane. The body includes alternating inner and outer curved regions, defining a zigzag pattern about a periphery of the clip. The body is biased towards a planar configuration lying in the plane and deflectable towards a transverse configuration extending out of the plane. Tines extend from the inner curved regions, the tines being oriented towards the central axis in the planar configuration, and parallel to the central axis in the transverse configuration. The tines may include primary tines and secondary tines that are shorter than the primary tines. The primary tines may be disposed on opposing inner curved regions and oriented towards one another such that they overlap in the planar configuration.

Claims

1. A vessel closure device, comprising:

an annular body defining a plane and disposed about a central axis at the center of an opening of the body, the body being movable between a generally planar, deployed configuration lying generally in the plane and a generally cylindrical, pre-deployment configuration extending out of the plane of the body, wherein the body is spring biased to move to the generally planar, deployed configuration from the generally cylindrical, pre-deployment configuration, the body having a serpentine orientation with a plurality of looped elements comprising alternating first and second curved regions, the first curved regions defining an inner periphery of the body and having an apex and the second curved regions defining an outer periphery of the body in the planar configuration; and

a plurality of tissue attachment features extending from the first curved regions, the attachment features extending from the apex of the respective first curved region and being oriented generally into the opening of the body in the planar, deployed configuration towards the central axis in a manner that does not interfere with insertion and removal of a procedural sheath through the opening, and generally parallel to the central axis in the generally cylindrical, pre-deployment configuration.

2. A device as in claim 1, wherein the attachment features comprise tines.

3. A device as in claim 1, wherein each of the attachment features extends along an axis that is offset from the central axis when the device is in the planar configuration.

4. A device as in claim 1, wherein each of the attachment features extends along an axis that is angled away from central axis when the device is in the planar configuration.

5. A device as in claim 1, wherein the annular body has a spring force that closes the annular body from the cylindrical configuration to the planar configuration pursuant to a generally linear rather than radial bias.

6. A vessel closure device, comprising:

an annular body defining a plane and disposed about a central axis at the center of an opening of the body, the body having a serpentine orientation and being movable between an expanded cylindrical, pre-deployment configuration extending out of the plane of the body and a generally planar compressed, deployed configuration, wherein the body is spring biased to move to the generally planar compressed, deployed configuration from the expanded cylindrical, pre-deployment configuration, and wherein the body applies a generally linear force to tissue as the body moves toward the planar compressed configuration; and

a plurality of tissue attachment features having a distal end, each of the plurality of tissue attachment features extending in a direction away from the body, for attaching to tissue, each tissue attachment feature having a longitudinal axis, wherein when the body is in the compressed configuration the distal end of each of the plurality of tissue attachment features is remote from the body, wherein a portion of the body adjacent the longitudinal axis, and extending from an inner periphery of the body towards an outer periphery of the body, extends towards the longitudinal axis in the compressed configuration and extends away from the longitudinal axis in the expanded configuration, such that the tissue engagement features engage the vessel in the generally planar, deployed configuration.

7. A device as in claim 6, wherein the attachment features are oriented generally into the opening of the body in the planar compressed configuration in a manner that does not interfere with insertion and removal of a procedural sheath through the opening, and generally parallel to the central axis in the expanded configuration.

8. A device as in claim 6, wherein the attachment features are tines.

9. A vessel closure device, comprising:

an annular body defining a plane and disposed about a central axis at the center of an opening of the body, the body being movable between a generally planar, deployed configuration lying generally in the plane and a generally cylindrical, pre-deployment configuration extending out of the plane of the body, wherein the body is spring biased to move to the generally planar, deployed configuration from the generally cylindrical, pre-deployment configuration, the body having a serpentine orientation with a plurality of looped elements comprising alternating first and second curved regions, the first curved regions defining an inner periphery of the body and having an apex and the second curved regions defining an outer periphery of the body in the planar configuration; and

a plurality of tines extending from the first curved regions, the tines extending from the apex of the respective first curved region and being oriented generally into the opening of the body in the planar, deployed configuration towards the central axis, and generally parallel to the central axis in the generally cylindrical, pre-deployment configuration.

10. A device as in claim 9, wherein each of the tines extends along an axis that is offset from the central axis when the device is in the planar configuration.

11. A device as in claim 9, wherein each of the tines extends along an axis that is angled away from central axis when the device is in the planar configuration.

12. A device as in claim 9, wherein the annular body has a spring force that closes the annular body from the cylindrical configuration to the planar configuration pursuant to a generally linear rather than radial bias.
