Abstract
Disclosed herein are terpolymers that can function as pressure-sensitive adhesives. The disclosed articles comprise the terpolymers adhered to a release liner. The disclosed implant devices comprise the pressure-sensitive adhesive terpolymer adhered to a surface thereof. The pressure-sensitive adhesive terpolymer can promote adhesion of the implant device to a location in a subject.
Claims4
An article, comprising:
- a pressure-sensitive adhesive (PSA) having a first adhesive surface and an opposing second adhesive surface,
- the pressure-sensitive adhesive (PSA) comprises a poly(D,L-lactide-co-glycolide-co-ε-caprolactone) having a molecular weight (Mw) of from 100,000 to 140,000 Daltons and a polydispersity index (PDI) of less than 2.0;
- wherein the poly(D,L-lactide-co-glycolide-co-ε-caprolactone) exhibits storage modulus (G′) values of from about 1.5×105 Pa to about 5.5×105 Pa, over a frequency of from about 0.1 to about 1 Hz;
- and
- exhibits storage modulus (G′) values of from about 1.0×106 Pa to about 4.0×106 Pa, over a frequency of from about 102 to about 104 Hz at 30° C.;
- the poly(D,L-lactide-co-glycolide-co-ε-caprolactone) comprising from 50 to 60 mol % caprolactone;
- and
- a bioactive agent selected from the group consisting of gentamicin, tobramycin, rifampin, and minocycline, or combinations thereof;
- and
- a release liner, wherein the release liner fully covers the first adhesive surface and the second adhesive surface of the pressure-sensitive adhesive.
