Abstract

A removable self-retaining suture system and methods for use thereof in emergency situations. The system comprises one or more self-retaining suture segments and a grasp engagement element. The system may be used for temporary wound closure in a trauma victim, and may be easily removed upon the availability of proper medical care to the victim.

First claim

What is claimed is:

1. A removable bidirectional self-retaining suture, the suture comprising:
a. a first end, a second end, and a periphery;
b. a plurality of retainers, the plurality of retainers located on a first portion of the suture between the first end of the suture and a first axial location on the suture for permitting movement of the suture through tissue in a direction of movement of the first end and preventing movement of the suture through tissue in a direction opposite the direction of movement of the first end, and the plurality of retainers on a second portion of the suture between the second end of the suture and a second axial location on the suture permitting movement of the suture through tissue in a direction of movement of the second end and preventing movement of the suture through tissue in a direction opposite the direction of movement of the second end; and
c. a grasp engagement element comprising a rigid continuous loop or polygon integrally formed with the suture between the first and second axial locations.

2. The suture of claim 1 , wherein the rigid continuous loop comprises a closed ring.

3. The suture of claim 1 , wherein the grasp engagement element has a periphery greater than the periphery of the suture.

4. The suture of claim 1 , wherein the suture further comprises a frangible portion between the grasp engagement element and the first and second axial locations for facilitating removal of the grasp engagement element from the suture.

5. The suture of claim 1 , further comprising a detachable connector connecting the grasp engagement element and the suture.

6. The suture of claim 1 , wherein the grasp engagement element comprises a different material than the rest of the suture.

7. A removable multidirectional self-retaining system comprising:
a. a grasp engagement element comprising a rigid continuous loop or polygon;
b. at least three suture segments, each suture segment having a plurality of retainers between a first end of the suture segment and a second end of the suture segment for permitting movement of the suture through tissue in a direction of movement of the first end and preventing movement of the suture segment through tissue in a direction opposite the direction of movement of the first end, and a second end of each suture segment being attached to the grasp engagement element such that the grasp engagement element is integrally formed with the plurality of suture segments at the second end.

8. The system of claim 7 , wherein the rigid continuous loop comprises a closed ring.

9. A method of emergency wound closure, comprising:
a. providing a self-retaining suture, the suture having suture segments, each suture segment having a plurality of retainers between a first and second end of the suture segment for permitting movement of the suture through tissue in a direction of movement of the first end and preventing movement of the suture through tissue in a direction opposite the direction of movement of the first end, and a grasp engagement element comprising a rigid continuous loop or polygon integrally formed with the suture segments at the second end of each suture segment;
b. positioning the grasp engagement element at least in part outside the wound;
c. inserting the first end of one of the suture segments into tissue at an insertion point at the wound; and,
d. drawing the first end of the one of the suture segments towards an end of the wound along a deployment path through tissue on alternating sides of the wound to an exit point outside the tissue.

10. The method of claim 9 , further comprising:
e. inserting the first end of another one of the suture segments into tissue at a second insertion point between the first and second ends of the wound, leaving a portion of the suture between the first and second insertion points;
f. drawing the first end of the another one of the suture segments towards the second end of the wound along a second deployment path through tissue on alternating sides of the wound to a second exit point; and,
g. severing the suture along the portion between the first and second insertion points for removal of the suture from the wound prior to provision of permanent treatment.

11. The method of claim 10 , wherein inserting the first end of the another one of the suture segments into tissue is performed before drawing the first end of the one of the suture segments towards the first end of the wound.

12. The method of claim 9 , wherein said wound is a stellate wound having at least three tissue apexes, wherein said self-retaining suture is a multidirectional self-retaining suture system comprising at least three suture segments, and wherein said method further comprises:
e. inserting the first end of a second suture segment into a second tissue apex and drawing the first end of the second suture segment out of the tissue; and,
f. inserting the first end of a third suture segment into tissue at a third tissue apex and drawing the first end of the third suture segment out of the tissue.
