Abstract
Abstract An implantable prosthesis and device and method for loading and delivering the implantable prosthesis to a trocar cannula. The implantable prosthesis includes a body portion sufficient to extend across and occlude a defect opening and a semi-rigid ring for supporting the body portion. The implantable prosthesis may be provided with a sufficient hoop strength to prevent the body portion from collapsing into the defect opening. A loading and delivery tool includes a main body with a lumen sized to collapse the implantable prosthesis. An elongated shaft is rotatable to wind the implant into a slender configuration and axially moveable to advance the rolled-up implant into the trocar cannula. A cartridge extends from the main body and holds the implant in a normal expanded configuration.

Dependent Claim
51 words
The implantable prosthesis recited in claim 1, further comprising: an implantable hoop carried by said pliable implantable sheet of mesh fabric between said body portion and said at least one anchoring portion, said implantable hoop being constructed and arranged to circumscribe the defect opening and being stiffer than said body portion.
Claim 4
Dependent Claim
43 words
The implantable prosthesis recited in claim 2 wherein said implantable prosthesis has a sufficient hoop strength to limit the deflection of said body portion into the defect opening when said hoop is positioned relative to the tissue or muscle defining the defect opening.
Claim 5

The implantable prosthesis recited in claim 2, wherein said at least one anchoring portion is co-planar with said body portion.
Claim 6
Dependent Claim
35 words
The implantable prosthesis recited in claim 2, wherein said at least one portion of said pliable sheet of barrier material is pivotable relative to said implantable hoop to reveal said at least one anchoring portion.
Claim 7
Dependent Claim
26 words
The implantable prosthesis recited in claim 2, wherein said at least one anchoring portion includes a plurality of anchoring portions uniformly spaced about said implantable hoop.
Claim 8
Dependent Claim
55 words
The implantable prosthesis recited in claim 2, wherein said implantable sheet of mesh fabric includes a substantially square shape and said hoop includes a substantially round shape, said hoop inscribing said implantable sheet of mesh fabric so that a portion of said implantable mesh fabric outside said hoop forms said at least one anchoring portion.
Claim 9
Dependent Claim
56 words
The implantable prosthesis recited in claim 1, wherein said pliable sheet of barrier material is attached to said implantable sheet of mesh fabric in a face-to-face relationship and said at least one portion of said pliable barrier material is liftable relative to said implantable sheet of mesh fabric to reveal said at least one anchoring portion.
Claim 10
Dependent Claim
36 words
The implantable prosthesis recited in claim 8, wherein said implantable sheet of mesh fabric has a fabric perimeter and said pliable sheet of barrier material has a barrier perimeter that is larger than said fabric perimeter.
Claim 11
Dependent Claim
22 words
The implantable prosthesis recited in claim 2, wherein said implantable hoop is integrally attached to said pliable implantable sheet of mesh fabric.
