Abstract
The present invention features soft tissue implants and methods for making same. The implants can includes a biocompatible film that is rendered porous due to the inclusion of uniformly or non-uniformly patterned cells, and the film has a thickness of less than about 0.015 inches in the event the starting material is non-porous and less than about 0.035 inches in the event the starting material is a microporous film. Multi-film implants can also be made.
Claims14
A non-woven soft tissue implant comprising a first porous biocompatible film having a plurality of unit cells and a second porous biocompatible film having a plurality of unit cells, the thickness of the implant being less than 0.015 inches,
- wherein each unit cell comprises a pore and a portion of the film extending around the perimeter of the pore to define the pore;
- and
- wherein the implant has a surface area ratio (Asu/Ac) of less than 1.5,
- wherein
- Asu=the three dimensional surface area of the unit cell, and
- Ac=the two dimensional area of the unit cell.
