Abstract
Layered materials for using in implants, such as hernia repair implants. The layered materials may include a first layer including a substrate (e.g., mesh) and a second layer including a sheet of anti-adhesive material. The layers may be attached at small attachment sites that are separated by regions in which the layers are not attached, to provide a highly compliant implant. The compliance of the implant may match that of a patient's body upon implantation and/or over time following implantation.
Claims18
A hernia repair graft comprising:
- a multiple layered structure, comprising:
- a first layer;
- a first stitching embroidered into the first layer in a first pattern;
- a second layer comprising one or more sheets of material having anti-adhesion properties;
- and
- a second stitching embroidered into the first and second layers in a second pattern, wherein the second stitching attaches the first layer to the second layer at a plurality of discrete attachment sites, wherein adjacent regions of the first and second layers between the plurality of discrete attachment sites may slide relative to each other.

A method of forming a hernia repair graft, the method comprising:
- forming a multiple layered structure by:
- embroidering a first stitching into a first layer, wherein the first stitching is embroidered in a first pattern;
- and
- embroidering a second stitching into the first layer and a second layer to attach the first and second layers at a plurality of discrete attachment sites, wherein the second layer includes one or more sheets of material having anti-adhesion properties, wherein the second stitching is embroidered in a second pattern, and wherein adjacent regions of the first and second layers between the plurality of discrete attachment sites may slide relative to each other.
