Patent ID: 8083805

Claim:
An absorbable endo-urological stent comprising a fiber-reinforced, multicomponent polymeric fully slit tube, wherein the slit extends along a longitudinal axis of the tube such that opposing edges of said slit can be compressively overlapped under stress within a rigid, tubular applicator to yield a partially rolled configuration having an outside diameter that is at least 2 percent less than that of the tube prior to slitting, such that when the stress is released at a site of a renal conduit upon discharging from the rigid tubular applicator the opposing edges spring back to acquire a diameter that is at least 2 percent larger than that of the renal conduit, the fiber-reinforcement comprising a coiled reinforcing fiber that is an extruded monofilament of a solid microdispersion made of one of the following: (a) a copoly-lactide dispersed phase in a copolyglycolide continuous phase, (b) a copoly-caprolactone dispersed phase in a copolyglycolide continuous phase, or (c) a copoly-caprolactone dispersed phase in a copoly-lactide continuous phase; wherein the dispersed phase is in the form of microspindles organized and overlapping along the monofilament axis thereby increasing the tensile modulus and resilience of the monofilament.
