Fiber-reinforced composite rings for intravaginal controlled drug delivery
First Claim
1. An intravaginal ring for the controlled delivery of a bioactive agent, said ring comprising a) a biocompatible matrix and b) a reinforcing, absorbable biodegradable fiber construct within said biocompatible matrix, wherein said biocompatible matrix further comprises an absorbable microparticulate polymer and a bioactive agent contained within said matrix, wherein said reinforcing, absorbable biodegradable fiber construct is formed from at least one cyclic monomer selected from the group consisting of glycolide, l-lactide, ε
- -caprolactone, p-dioxanone and trimethylene carbonate.

Abstract
A fiber-reinforced composite ring for the controlled release of at least one bioactive agent includes a biocompatible matrix reinforced with absorbable/biodegradable fibers capable of providing the mechanical properties needed for inserting and maintaining the ring in a body cavity for a desired period of time. Such ring system as can be used for the intravaginal, intraperitoneal, and subcutaneous delivery of at least one bioactive agent, including those used as contraceptives, antimicrobial agents, and/or antiviral agents, as well as those for the treatment of cancer.
