Abstract

The repair fabric includes a dual bar warp knit mesh for use in repairing soft tissue and muscle wall defects, including hernia repair and chest wall reconstruction. The repair fabric may be produced according to a first bar pattern chain of 4/2 4/6 4/2 6/8 6/4 6/8 and a second bar pattern chain of 6/8 2/0 6/8 4/2 8/10 4/2.

Claims (12)

1. An implantable prosthetic repair fabric, comprising:

a biologically compatible, implantable dual bar warp knit mesh including a plurality of primary pores defined by knitted strands of filaments, each primary pore including a plurality of secondary pores that are defined by a pair of filaments extending across each primary pore, the knit mesh produced with closed loops according to a first bar pattern chain of 4/2 4/6 4/2 6/8 6/4 6/8 and a second bar pattern chain of 6/8 2/0 6/8 4/2 8/10 4/2.

2. The implantable prosthetic repair fabric according to claim 1 , wherein the mesh is formed of knitted monofilaments.

3. The implantable prosthetic repair fabric according to claim 2 , wherein the monofilaments include polypropylene monofilament.
