Closure device and methods for making and using them
First Claim
1. A device for engaging tissue at a puncture site and facilitating closure of the puncture site, comprising:
- an annular-shaped body defining a plane and disposed about a central axis extending substantially normal to the plane, the body comprising a plurality of looped elements extending about a periphery of the body to form an endless sinusoidal pattern;
a plurality of tines having free distal ends extending from the looped elements through the central axis of the annular-shaped body; and
the body and tines comprising a resilient material so that the body and tines normally lie in a planar, deployed first configuration, the material of the body and tines being sufficiently resilient so that when a force is applied to the tines they are forced from the planar, deployed first configuration into a transverse, pre-deployment second configuration in which the tines and free distal ends are spread open for insertion of the free distal ends into the tissue around the puncture site, and thereafter the body and tines will automatically return toward the first configuration so as to engage the puncture site and facilitate closure thereof after the force is removed.

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.

10. A device for engaging tissue at a puncture site and facilitating closure of the puncture site, comprising:
-
an annular-shaped body defining a plane and disposed about a central axis extending substantially normal to the plane, the body comprising a plurality of looped elements extending about a periphery of the body to form an endless sinusoidal pattern; a plurality of arcuate tines having free distal ends extending from the looped elements through the central axis of the generally annular-shaped body; and the body and arcuate tines comprising a resilient material so that the body and arcuate tines normally lie in a planar, deployed first configuration, the material of the body and arcuate tines being sufficiently resilient so that when a force is applied to the arcuate tines they are forced from the planar, deployed first configuration into a transverse, pre-deployment second configuration in which the arcuate tines and free distal ends are spread open for insertion of the free distal ends into the tissue around the puncture site, and thereafter the body and arcuate tines will automatically return toward the first configuration so as to engage the puncture site and facilitate closure thereof after the force is removed.

11. A device for engaging tissue at a puncture site and facilitating closure of the puncture site, comprising:
-
an annular-shaped body defining a plane and disposed about a central axis extending substantially normal to the plane, the body comprising a plurality of looped elements extending about a periphery of the body to form an endless sinusoidal pattern; a plurality of substantially straight tines having free distal ends extending from the looped elements through the central axis of the generally annular-shaped body ; and the body and tines comprising a resilient material so that the body and tines normally lie in a planar, deployed first configuration, the material of the body and tines being sufficiently resilient so that when a force is applied to the tines they are forced from the planar, deployed first configuration into a transverse, pre-deployment second configuration in which the tines and free distal ends are spread open for insertion of the free distal ends into the tissue around the puncture site, and thereafter the body and tines will automatically return toward the first configuration so as to engage the puncture site and facilitate closure thereof after the force is removed. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
