PCT No. PCT/SE92/00404 Sec. 371 Date Feb. 7, 1994 Sec. 102(e) Date Feb. 7, 1994 PCT Filed Jun. 10, 1992 PCT Pub. No. WO92/22336 PCT Pub. Date Dec. 23, 1992.Method of producing a microstructure in a bioresorbable element comprising a material consisting of a major portion of at least one polymer selected from the group including aliphatic polyesters and aliphatic polycarbonates and copolymers thereof. The microstructure is accomplished by using an excimer laser which is operated at a maximum wavelength of 248 nm.
