Patent ID: 8011370

Claim:
A method of contraception, comprising: delivering into a fallopian tube a bioabsorbable implant having an implant body comprising a plurality of biodegradable fibers which have a crimped configuration when in an unstressed condition, each of the fibers extending from a proximal end of the implant body to a distal end thereof, the fibers being joined at least one of the proximal end and the distal end of the implant body and being loosely arranged, non-knit and non-woven between the proximal end and the distal end; shortening the implant body after delivering the implant body into the fallopian tube wherein shortening the implant body comprises moving at least one of the proximal end and distal end of the implant body toward the other; and occluding the fallopian tube with the implant; wherein: the implant further comprises a string that extends generally longitudinally from a location along the implant body to the proximal end, and proximally from the proximal end; each of the fibers extends the length of the implant body to the distal end, and is joined to the string at the distal end; and shortening the implant body comprises pulling the string proximally.
