Compressible soft tissue prostheses and related methods
Implantable prostheses and related methods are generally described. In some embodiments, the prosthesis may be used for soft tissue reconstruction. The prosthesis may be formed from a three-dimensional load-bearing porous scaffold having interconnected networks of pores, thereby enabling tissue infiltration and allowing native tissue, blood vessels, and cells to colonize on the scaffold. In some embodiments, the scaffold may be formed from a biodegradable material such that it may degrade during the tissue infiltration process, leaving native tissue. In some embodiments, the stent may be formed from a triple periodic minimum surface, such as a helical tetracosahedron, to achieve high compressibility and high porosity. The compressibility of the implant may simulate the mechanical behavior of native tissue and allow the implant to be delivered through a small incision site (e.g., with an implant delivery funnel).
