Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A polymeric drug delivery device comprising: a biocompatible polymeric matrix further comprising an absorbable microparticulate ion-exchanging polymer; an at least partially absorbable reinforcing construct comprising one or more polymers synthesized from monomers selected from the group consisting of glycolide, l-lactide, dl-lactide, ε-capralactone, p-dioxanone, trimethylene carbonate, morpholinedione or combinations thereof; an at least partially absor…
