Abstract:
1. A method of contraception comprising: delivering into a fallopian tube an implant comprising a plurality of loose, bioabsorbable fibers that are radially bulked when in an unstressed condition, the fibers having a crimped appearance in the unstressed condition such that each fiber includes a plurality of closely spaced radial or angular bends along its length, the bends making each fiber radially self-expanding upon removal of a compressive force, the fibers extending generally longitudinally from a proximal end of the implant to a distal end thereof, the fibers being textured enough in aggregate to span the cross-section of the fallopian tube, the fibers forming a radially outermost, tissue-engaging surface of the implant, the tissue-engaging surface surrounding the implant; radially expanding the implant within the fallopian tube; and occluding the fallopian tube with the implant.
