Abstract
Official abstract text for this publication.
A self-sealing shell useful as a component of a soft fluid-filled prosthetic implant is provided. The shell is at least partly constructed of a wall made of a colloid of an elastomeric polymer matrix and particles of a water-swellable material distributed therein.
First claim
Opening claim text (preview).
What is claimed is: 1. An implantable article of manufacture useful as a component of an inflatable prosthesis, the article made by the steps of: providing a curable polymer-based liquid; distributing a plurality of solid, water swellable particles in the liquid to form a fluid mixture comprising a liquid polymer and solid, water swellable particles; allowing the mixture to solidify to form a polymeric matrix having solid, water swellable particles occupying enclosed spaces in the matrix; and forming the mixture into a wall of an inflatable prosthesis; wherein, when the wall is contacted with an aqueous fluid, the water swellable particles expand and the wall becomes self-sealing to a needle puncture. 2. The article of claim 1 wherein the wall is not self sealing to a needle puncture when it is in a dry state. 3. The article of claim 1 wherein the particles comprise hydrogel particles. 4. The article of claim 1 wherein the particles comprise a hydrogel comprising polyethylene glycol. 5. The article of claim 1 wherein the water swellable particles make up between about 2% to about 40% by weight of the mixture. 6. The article of claim 1 wherein the water swellable particles make up about 25% by weight of the mixture.
