Abstract: An implantable radially-porous, polymeric, scaffold device configured for insertion into and obstruct a Fallopian tube formed of a polymer such as collagen, nanocellulose, xanthan gum, konjac glucomannan, alginate, agar, agarose, chitin, chitosan, chitosan-alginate polylactic acid (PLA), polygultamic acid (PGA), polycaprolactone, or polydioxanone. The device is compressed and placed within a first end of an insertion tube adapted for insertion through the cervix into the Fallopian tube; the insertion tube having a plunger to expel the device from the tube. The method includes using the insertion tube containing the radially freeze-cast and freeze-dried implant. Under hysteroscopic guidance the tube is positioned in the Fallopian tube and the implant is expelled into the Fallopian tube. Epithelium of the Fallopian tube is disrupted; and ingrowth of cells into the implant is permitted.
