Surgical Implants
Surgical implants include a surgical mesh which includes at least one shape memory polymer capable of transitioning the surgical mesh between a first configuration and a second configuration.
1 . A surgical mesh comprising:
a plurality of filaments including at least one shape memory filament selected from the group consisting of polydioxanone, polylactide, poly(trimethylene carbonate) and copolymers thereof, wherein the shape memory filament transitions the surgical mesh from a first configuration to a second configuration.
2 . The surgical mesh of claim 1 , wherein the shape memory filament comprises a block copolymer of polydioxanone and polylactide.
3 . The surgical mesh of claim 2 , wherein the polydioxanone is present in an amount from about 5 mol % to about 20 mol % of the copolymer and the polylactide is present in an amount from about 80 mol % to about 95 mol % of the copolymer.
4 . The surgical mesh of claim 1 , wherein the shape memory filament comprises a block copolymer of poly(trimethylene carbonate) and polylactide.
5 . The surgical mesh of claim 4 , wherein the poly(trimethylene carbonate) is present in an amount from about 5 mol % to about 20 mol % of the copolymer and the polylactide is present in an amount from about 80 mol % to about 95 mol % of the copolymer.
6 . The surgical mesh of claim 1 , further comprising a grip member.
7 . The surgical mesh of claim 1 , wherein the shape memory filament transitions the mesh from the first configuration to the second configuration at about 37° C.
8 . The surgical mesh of claim 1 , wherein the first configuration is selected from the group consisting of rolled, folded, crumpled, curled, furled, and combinations thereof.
9 . The surgical mesh of claim 1 , wherein the second configuration is selected from the group consisting of unrolled, uncurled, unfolded, unfurled, uncrumpled, and combinations thereof.
10 . The surgical mesh of claim 1 , wherein the second configuration is generally flat.
11 . The surgical mesh of claim 1 , wherein the plurality of filaments is knit, braided, non-woven or woven.
12 . The surgical mesh of claim 1 , further comprising a bioactive agent.
13 . The surgical mesh of claim 1 , wherein the mesh comprises a monofilament or multifilament mesh.
14 . A method of making a surgical mesh, the method comprising:
incorporating the at least one shape memory filament into a plurality of yarns;
incorporating the plurality of yarns containing the shape memory filament into the surgical mesh; and
conditioning the at least one shape memory filament to transition the mesh between a first configuration and a second configuration.
15 . The method of claim 14 , wherein the conditioning step further includes inserting the mesh in a first configuration into a mold and heating the mesh to a permanent temperature of from about 20° C. to about 55° C.
16 . The method of claim 14 , wherein the first configuration comprises a generally rolled, crumpled, curled, folded, or furled configuration.
17 . The method of claim 14 , wherein the mesh transitions from the first configuration to the second configuration in situ.
18 . The method of claim 14 , wherein the second configuration comprises a generally unrolled, uncrumpled, uncurled, unfolded, unfurled, or flat configuration.
19 . The method of claim 18 , wherein the at least one shape memory filament comprises a permanent shape in the second configuration.
20 . The method of claim 14 , wherein the mesh comprises the plurality of yarns in a 2-dimensional or 3-dimensional construct.
