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 of first filaments and a second bar pattern chain of 6/8 2/0 6/8 4/2 8/10 4/2 of second filaments. The diameter of the first filaments being different from the diameter of the second filaments.
Claims38
An implantable prosthetic repair fabric, comprising:
- a biologically compatible, implantable dual bar warp knit mesh 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, the mesh is knitted of a first monofilament having a first diameter and a second monofilament having a second diameter which is greater than the first diameter, the first monofilament being knitted according to the first bar pattern chain and the second monofilament being knitted according to the second bar pattern chain.
An implantable prosthetic repair fabric, comprising:
- a knit mesh that includes a plurality of generally polygonal shaped primary pores defined by knitted strands of first filaments having a first diameter;
- and
- a pair of individual second filaments that extend across each primary pore to define a plurality of secondary pores within each primary pore, each of the pair of individual second filaments extending substantially parallel to one another, each of the second filaments having a second diameter which is greater than the first diameter.
An implantable prosthetic repair fabric, comprising:
- a biologically compatible, implantable dual bar warp knit mesh 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, the mesh having a ball burst strength of 35 lbs to 42.4 lbs, a suture pullout strength of 9 lbs to 11 lbs in the machine direction and 7.5 lbs to 9.5 lbs in the cross direction, and a tensile strength of 11.8 lbs to 16.8 lbs in the machine direction and 34.2 lbs to 47.2 lbs in the cross direction.
