## Abstract

The present invention features soft tissue implants comprising major and minor struts 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.

## Claims

### Claim 1

A non-woven soft tissue implant comprising a first porous biocompatible film having a plurality of cells and a second porous biocompatible film having a plurality of cells, the thickness of the non-woven soft tissue implant being less than 0.015 inches, wherein the first porous biocompatible film comprises a plurality of major struts that are made of the first porous biocompatible film and have a width of 0.020 inches to 0.100 inches, and a plurality of minor struts that are made of the first porous biocompatible film and have a width of 0.001 inches to 0.024 inches, wherein the second porous biocompatible film comprises a plurality of major struts that are made of the second porous biocompatible film and have a width of 0.020 inches to 0.100 inches, and a plurality of minor struts that are made of the second porous biocompatible film and have a width of 0.001 inches to 0.024 inches.

### Claim 2 (depends on 1)

The non-woven soft tissue implant of claim 1, wherein the first porous biocompatible film and the second porous biocompatible film consist of the same material or materials.

### Claim 3 (depends on 1)

The non-woven soft tissue implant of claim 1, wherein the first porous biocompatible film and the second porous biocompatible film consist of different materials.

### Claim 4 (depends on 3)

The non-woven soft tissue implant of claim 3, wherein the first porous biocompatible film or the second porous biocompatible film includes a bioresorbable material and a rate at which the first porous biocompatible film is resorbed within a body is different from a rate at which the second porous biocompatible film is resorbed in the body.

### Claim 5 (depends on 1)

The non-woven soft tissue implant of claim 1, wherein the first porous biocompatible film and the second porous biocompatible film are of substantially the same size and a surface of the first porous biocompatible film adheres to a surface of the second porous biocompatible film.

### Claim 6 (depends on 1)

The non-woven soft tissue implant of claim 1, wherein the first or the second porous biocompatible film comprises an absorbable polymer or copolymer.

### Claim 7 (depends on 1)

The non-woven soft tissue implant of claim 1, wherein the first porous biocompatible film or the second porous biocompatible film comprises a cell of the respective plurality of cells having a diameter, measured along the longest axis of the cell, of 10 micrometers to 10,000 micrometers; of 1,500 micrometers to 5,000 micrometers; or of 50 micrometers to 100 micrometers.

### Claim 8 (depends on 1)

The non-woven soft tissue implant of claim 1, further comprising a film that increases tear resistance.
