  • Publication number: 20060085063
    Abstract: In one aspect, the invention relates to a synthetic conduit comprising a substantially tubular body comprising substantially circumferential polymer fibers; wherein the body has an exterior surface, an interior surface, and a lumen extending therethrough; and wherein the body has microscale features disposed at the interior surface. In a further aspect, cells can be optionally adhered to the exterior and/or interior surface of the substantially tubular body. In various aspects, the conduit can be used as a vascular prosthesis, a stent, or a nerve regeneration scaffold. Methods of preparing and implanting same are also provided. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

  • Publication number: 20060052471
    Abstract: The present invention relates to novel initiator systems, methods of use, and cured composition for dental, orthopedic and drug delivery purpose. Specifically, it relates to a crosslinkable prepolymer where crosslinking is initiated by a two part system and a composition comprising an admixture of a resorbable bone substitute and a crosslinkable prepolymer. It also relates to the composition formed by crosslinking the admixture and a delivery system for cross-linking the polymer.
