1. A suture comprising:
- an elongated body having a first end and a second end;
a plurality of barbs projecting from said body, each barb facing a direction and being adapted to resist movement in tissue in a direction opposite to the direction that the barb faces;
said barbs including an underside that is adjacent to the elongated body;
said underside of barbs including projections that are adapted to engage tissue; and
wherein barbs shield the projections from engagement in tissue.

Abstract
A barbed suture with a first end and a second end and a body with a plurality of barbs extending from the body. Each barb causes the suture to resist movement in an opposite direction from which the barb faces. Projections extend from said suture. The projections can also engage tissue. The barbs cover the projections when the first end of the suture is moved in tissue and exposes the projections in order to engage tissue when the suture is moved in the direction of the second end through tissue.

12. A suture comprising:
-
an elongated body having a first end and a second end; a plurality of barbs projecting from said body, each barb facing in a direction of motion of the first end of the suture through tissue and being adapted to resist movement in tissue in a direction of motion of the second end of the suture through tissue, said barbs having tissue engaging ends that are directed toward the second end; a plurality of projections, which projections point in a direction other than the direction that said barb ends are directed; said projections are adapted to engage tissue; and wherein barbs shield the projections from engagement in tissue. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A suture comprising:
-
an elongated body having a first end and a second end; a plurality of barbs projecting from said body, each barb facing a direction of motion of the first end of the suture through tissue and being adapted to resist movement in tissue in a direction of motion of the second end of the suture through tissue, said barbs having tissue engaging ends that are directed toward the second end; a plurality of projections, which projections point in a direction other than the direction that said barb ends are directed; said projections are adapted to engage tissue; wherein said barbs are larger than said projections; and wherein barbs shield the projections from engagement in tissue when said barbs are disposed against said body of said suture.
