Abstract
Medical devices or components for medical devices formed from bioabsorbable elastomers comprising a random copolymer are disclosed. The random copolymer is a copolymer of from about 30 to about 70 weight percent of: a) .epsilon.-caprolactone, trimethylene carbonate, an ether lactone, or a mixture of these, and b) the balance being substantially glycolide, para-dioxanone, or a mixture of these. The random copolymers surprisingly exhibit elastomeric properties, and the copolymers are bioabsorbable. The combination of physical and biological properties of these elastomeric copolymers are particularly well-suited for numerous medical and surgical applications.
Claims9
An elastomeric suture formed from a bioabsorbable elastomer wherein the elastomer consists essentially of a random copolymer of:
- a) from about 35 to about 45 weight percent of a first monomer selected from the group consisting of .epsilon.-caprolactone, trimethylene carbonate, and ether lactone and combinations thereof, and b) the balance of the copolmer being substantially a second monomer selected from the group consisting of glycolide, para-dioxanone and combinations thereof, wherein the random copolymer exhibits an inherent viscosity of from about 1.0 dL/g to about 2.0 dL/g and exhibits a percent elongation greater than 500 percent.
A bioabsorbable elastomer wherein the elastomer consists essentially of a random copolymer of:
- a) from about 40 to about 45 weight percent of a first monomer selected from the group consisting of .epsilon.-caprolactone, trimethylene carbonate, an ether lactone and combinations thereof, and b) the balance of the copolymer being substantially a second monomer selected from the group consisting of glycolide, para-dioxanone and combinations exhibiting a percent elongation of greater than 500 percent.
