Bi-directional barbed suture
First Claim
1. A surgical suture comprising:
- a monofilament core extending along a length thereof between a first end and a second end;
a plurality of sets of first and second projections extending outwardly from the core in a manner such that each set is longitudinally aligned along the length of the core, and positioned at different points along said length and between the first and second ends thereof, wherein the first projections extend outwardly from the core to a free distal end so as to point in a direction toward the first end of the suture and the second projections extend outwardly from the core to a free distal end so as to point in a direction toward the second end of the suture, and wherein the first projections extend outwardly from the core by a greater distance than the second projections, have an outer periphery greater than an outer periphery of the second projections and that substantially shields the outer periphery of the second projection when viewed along a longitudinal axis of the core, and are adapted to bend toward the second projections to overlap and sufficiently cover at least a distal portion of the respective second projections when the suture is drawn through tissue by the second end so as to substantially prevent the second projections from engaging tissue when drawn through said tissue.

Abstract
Surgical sutures having a core extending along a length thereof between a first end and a second end, and a plurality of sets of first and second projections, wherein the first projections extend in a direction of a first end of the suture and the second projections extend in a direction of a second end of the suture. The first projections may be sized and shaped, and positioned relative to the second projections so as to be capable of substantially shielding the second projections when the surgical suture is drawn through tissue by the second end thereof. The first projections may additionally or alternatively be capable of overlapping and substantially covering a distal end of the respective second projections when the suture is drawn through tissue by the second end.

8. A surgical suture comprising:
a plurality of sets of first and second barbs extending outwardly from a non-planar, monofilament suture core in a manner such that each set is longitudinally aligned along the length of the suture core and positioned at different points along a length of said surgical suture between first and second ends of said surgical suture, wherein for each of the plurality of sets, the first barb extends outwardly from the core to a free distal end so as to point in a direction toward a first end of the suture and the second barb extends outwardly from the core to a free distal end so as to point in a direction toward a second end of the suture, and the first barb extends outwardly from the core a greater distance than the second barb, has an outer periphery greater than an outer periphery of the second barb and that substantially shields the outer periphery of the second barb when viewed along a longitudinal axis of the core, and is adapted to bend toward the second barb to overlap a sufficient portion of the distal end of the second barb to substantially prevent said second barb from grasping tissue when drawn through said tissue. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A surgical suture comprising:
-
a monofilament core extending along a length thereof between a first end and a second end; a plurality of sets of first and second projections each extending outwardly from the core in a manner such that each set is longitudinally aligned along the length of the core, and positioned at different points along said length between the first and second ends thereof, wherein the first projections extend outwardly from the core to a free distal end so as to point in a direction of a first end of the suture and the second projections extend outwardly from the core to a free distal end so as to point in a direction of a second end of the suture; and wherein the first projections are sized and shaped, and positioned relative to the second projections so as to extend outwardly from the core a greater distance than the second projections, have an outer periphery greater than an outer periphery of the second projections and that substantially shields the outer periphery of the second projection when viewed along a longitudinal axis of the core, and as so as to be adapted to bend toward the second projections to sufficiently shield the second projections when the surgical suture is drawn through tissue by the second end thereof to thereby substantially prevent said second projection from grasping tissue when drawn therethrough. - View Dependent Claims (17, 18, 19)
