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.

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. - View Dependent Claims (8)

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. - View Dependent Claims (10, 11, 12)
