Implantable prothesis for minimally invasive hernia repair

An implantable prosthesis for repairing an indirect inguinal hernial defect comprising:

• a piece of biocompatible material having a preformed three-dimensional shape and defined by an outer edge, the piece having a lateral side and an opposite medial side extending along a medial-lateral axis and a superior side and an opposite inferior side extending along a superior-inferior axis, and the outer edge including a convex lateral outer edge, a medial outer edge, a superior outer edge including one or more concave portions, and an inferior outer edge including one or more concave portions, the piece including:
• an upper portion including a spherical cap extending between the superior outer edge and an interior edge extending from the lateral side to the medial side, the interior edge including first and second bifurcated portions on a medial end thereof,
• a lower portion extending between the interior edge and the inferior outer edge, the lower portion forming a wavy-shaped wall, and
• a crease portion on the medial side and defined between the first and second bifurcated end portions on the medial end thereof.

An implantable prosthesis for repairing a bilateral inguinal hernial defect comprising:

• a piece of biocompatible material having a preformed three-dimensional shape and defined by an outer edge including a first convex outer lateral edge, a second convex lateral edge opposite the first convex outer lateral edge, a superior outer edge, and an inferior outer edge opposite the superior outer edge, the piece including a first part and a second part,
• the first section including:
• a first lateral side opposite a first medial side extending along a first medial-lateral axis of the first section and a first superior side opposite a first inferior side extending along a first superior-inferior axis of the first section,
• a first upper portion including a spherical cap extending between a first portion of the superior outer edge and a first interior edge, the first interior edge extending from the first lateral side to the first medial side of the first section, the first interior edge including first and second bifurcated portions on a medial end thereof,
• a first lower portion extending between the first interior edge and a first portion of the inferior outer edge, the first lower portion forming a first wavy-shaped wall,
• a first crease portion on the first medial portion and defined between the first and second bifurcated portions of the first crease on the medial end thereof, and,
• the second section including:
• a second lateral side opposite a second medial side extending along a second medial-lateral axis of the second section and a second superior side opposite a second inferior side extending along a second superior-inferior axis of the second section,
• a second upper portion including a spherical cap extending between a second portion of the superior outer edge and a second interior edge extending from the second lateral side to the second medial side, the second interior edge including a third and fourth bifurcated portion on a medial end thereof,
• a second lower portion extending between the second interior edge and a second portion of the inferior outer edge, the second lower portion forming a second wavy-shaped wall,
• a second crease portion on the second medial portion and defined between the third and fourth bifurcated portions of the second crease on the medial end thereof,
• wherein the first and second medial sides of the first and second sections form a central band between the first and second lateral sides across a face of the piece of biocompatible material.
