Implantable prosthesis

An implantable prosthesis for repairing a tissue or muscle wall defect, the implantable prosthesis comprising:

• a patch of prosthetic repair fabric including a body portion that is constructed and arranged to cover at least a portion of the tissue or muscle wall defect and an anchoring portion that is constructed and arranged to secure the patch to host tissue or muscle, the patch further including a preformed region that is constructed and arranged to reduce the incidence of the detrimental effect of tension at the anchoring portion when the patch is secured to the tissue or muscle and a force is applied at the tissue or muscle wall defect and/or to compensate for contraction of the patch relative to the tissue or muscle wall defect due to tissue shrinkage during scarification, the preformed region having a three-dimensional shape and the anchoring portion being substantially planar, the body portion and the anchoring portion being integrally formed from a sheet of repair fabric.

An implantable prosthesis for repairing a tissue or muscle wall defect, the implantable prosthesis comprising:

• a patch of prosthetic repair fabric including a body portion that is constructed and arranged to cover at least a portion of the tissue or muscle wall defect and an anchoring portion that is constructed and arranged to secure the patch to host tissue or muscle, the patch further including a preformed region that is constructed and arranged to reduce the incidence of the detrimental effect of tension at the anchoring portion when the patch is secured to the tissue or muscle and a force is applied at the tissue or muscle wall defect and/or to compensate for contraction of the patch relative to the tissue or muscle wall defect due to tissue shrinkage during scarification, the body portion having a three-dimensional shape and including the preformed region, wherein the body portion include a preformed dome having an open end that is configured to be disposed over the tissue or muscle wall defect.

An implantable prosthesis for repairing a tissue or muscle wall defect, the implantable prosthesis comprising:

• a patch of an implantable layer of mesh fabric including a body portion having a preformed three-dimensional shape that is constructed and arranged to cover at least a portion of the tissue or muscle wall defect and an anchoring portion extending from the body portion that is constructed and arranged to secure the implantable prosthesis to host tissue or muscle, the body portion having a cavity with an open end that is configured to be disposed over the tissue or muscle wall defect.

An implantable prosthesis for repairing a tissue or muscle wall defect, the implantable prosthesis comprising:

• a prosthetic repair fabric including a body portion that is constructed and arranged to overlie at least a portion of the tissue or muscle wall defect and an anchoring portion that is constructed and arranged to secure the prosthetic repair fabric to tissue or muscle adjacent the tissue or muscle wall defect, the prosthetic repair fabric including a plurality of preformed indicia on the anchoring portion that correspond to desired anchoring locations between the implantable prosthesis and the tissue or muscle, the body portion having a three-dimensional shape and including a preformed dome having an open end that is configured to be disposed over the tissue or muscle wall defect.

A method of repairing a tissue or muscle wall defect, the method comprising steps of:

• (a) providing an implantable prosthesis including a patch having a body portion for covering the tissue or muscle wall defect and an anchoring portion for securing the implantable prosthesis to host tissue or muscle, the implantable prosthesis being preformed with a region that is constructed and arranged to reduce the incidence of detrimental tension at the anchoring portion when the patch is secured to the tissue or muscle and a force is applied at the tissue or muscle wall defect and/or to compensate for contraction of the patch relative to the tissue or muscle wall defect to reduce the incidence of detrimental effects due to tissue shrinkage during scarification, the preformed region including a three-dimensional shape and a dome having an open end;
• and
• (b) implanting the implantable prosthesis with the body portion covering at least a portion of the tissue or muscle wall defect.

A method of repairing a tissue or muscle wall defect, the method comprising steps of:

• and
• (b) implanting the implantable prosthesis with the cavity covering at least a portion of the tissue or muscle wall defect.

An implantable prosthesis for repairing a tissue or muscle wall defect in the inguinal region, the implantable inguinal region prosthesis comprising:

• a flexible patch of prosthetic repair fabric having openings constructed and arranged for tissue ingrowth, said patch being elongated in a medial to lateral direction and including a roughly D-shaped medial portion,
• said medial portion including a pre-formed dome that projects outwardly from the patch, said dome defining a cavity for covering at least a portion of the tissue or muscle wall defect.
