Welded Looped Suture
A suture includes an elongate body and a filler material. The elongate body includes a distal end having first and second overlapping sections forming a loop. The filler material is disposed within at least a portion of a seam defined between the first and second overlapping sections of the elongate body to reinforce the first and second overlapping sections. A method of forming a reinforced looped suture includes providing a suture including an elongate body including a distal end having first and second overlapping sections defining a loop, and applying a filler material to a seam defined between the first and second overlapping sections.
1 . A suture comprising:
an elongate body including a distal end having first and second overlapping sections forming a loop; and
a filler material disposed within at least a portion of a seam defined between the first and second overlapping sections of the elongate body.
2 . The suture of claim 1 , wherein the filler material reinforces the first and second overlapping sections.
3 . The suture of claim 1 , wherein the elongate body and the filler material comprise a same polymeric material.
4 . The suture of claim 1 , wherein the elongate body and the filler material comprise different polymeric materials.
5 . The suture of claim 1 , wherein the filler material comprises a thermoplastic polymer.
6 . The suture of claim 1 , wherein the first and second overlapping sections further comprise a taper in a proximal end thereof.
7 . The suture of claim 1 , wherein the first and second overlapping sections are substantially parallel to each other.
8 . The suture of claim 1 , wherein the first and second overlapping sections are intertwined.
9 . The suture of claim 1 , further comprising a bioactive agent.
10 . A method of forming a reinforced looped suture, the method comprising the steps of:
providing a suture including an elongate body including a distal end having first and second overlapping sections defining a loop; and
applying a filler material to a seam defined between the first and second overlapping sections.
11 . The method of claim 10 , wherein the step of applying the filler material further comprises the step of spraying the filler material towards the seam of the first and second overlapping sections of the elongate body.
12 . The method of claim 10 , wherein the step of applying the filler material further comprises the step of applying a pre-molded filler within the seam of the first and second overlapping sections of the elongate body.
13 . The method of claim 10 , wherein the step of applying the filler material further comprises the step of providing the filler material at a temperature that is sufficient to locally melt the first and second overlapping sections of the elongate body to create a reinforced joined segment.
14 . The method of claim 13 , wherein the step of applying the filler material further comprises applying a filler material comprising a same material as the first and second overlapping sections to form a homogenous joined segment.
15 . The method of claim 10 , further comprising the step of welding the filler material to the first and second overlapping sections to create a reinforced joined segment.
16 . The method of claim 15 , wherein the step of welding is accomplished by application of one of RF, ultrasonic, laser, electrical arc discharge, and thermal energy to the looped suture.
