RETICULATED ELASTROMERIC MATRICES, THEIR MANUFACTURE AND USE IN IMPLANTABLE DEVICES

摘要

An implantable device comprising;a reticulated resiliently-compressible elastomeric matrix, formed by a reticulation process comprising combustion or chemical reticulation, said elastomeric matrix comprising a material selected from the group consisting of: (i) polyurethane.(ii) poly(urea-urethane) (iii) polycarbonate polyurethane.(iv) polycarbonate poly(urea-urethane).(v) any polymer formed by the reaction of an isocyanate with a polyol selected from the group consisting of a polycarbonate polyol, a polysiloxane polyol, a hydrocarbon polyol, or any combination thereof: and (vi) any combination thereof:wherein the matrix comprises a plurality of interconnected struts defining a continuous interconnected network of pores.
