A biodegradable, biocompatible, resorbable ureteral stent made of a biodegradable polymer composition and having a tensile strength of at least about 500 psi, an elongation greater than about 10% and a Shore A hardness of about 50 to 100. The polymer composition preferably comprises a terpolymer of L(-)lactide, glycolide and epsilon-caprolactone and the speed of resorption of the stent can be controlled by varying the molecular weight. This invention includes a method for treating ureteral obstructions or impairments by utilizing a biodegradable, biocompatible, resorbable infusion stent. |
