Abstract
A composite filament that is made of collagen and polycaprolactone. The collagen can be either a crosslinked or an uncrosslinked collagen. The composite is formed by combining either the crosslinked or uncrosslinked collagen at a melt temperature that is lower than a denaturing temperature of either the crosslinked or uncrosslinked collagen.
Claims4
A surgical suture construct comprising:
- a composite filament forming the core of the surgical suture construct, the composite formed by an uncrosslinked collagen blended with polycaprolactone that is extruded into a composite filament at a processing temperature below 45° C.;
- a plurality of braided polyester and polyethylene fibers surrounding the composite filament to form the surgical suture;
- wherein the composite filament is configured to be a scaffold for tissue ingrowth and the braided fibers provide mechanical reinforcement to the surgical suture construct.
A surgical suture construct comprising:
- a composite filament forming the core of the surgical suture construct, the composite formed by a crosslinked collagen blended with polycaprolactone that is extruded into a composite filament at a processing temperature below 100° C.;
- a plurality of braided polyester and polyethylene fibers surrounding the composite filament to form the surgical suture;
- wherein the composite filament is configured to be a scaffold for tissue ingrowth and the braided fibers provide mechanical reinforcement to the surgical suture construct.
A bioabsorbable composite material comprising:
- uncrosslinked collagen;
- and
- a polymer blended with the uncrosslinked collagen;
- wherein the polymer has a melt temperature that is lower than a denaturing temperature of the uncrosslinked collagen.
