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.
[ We claim:] [1.] An implantable prosthesis for occluding the opening of a tissue or muscle defect, said implantable prosthesis being deliverable to a surgical site through a cannula and comprising:a pliable implantable mesh fabric having a plurality of interstices constructed and arranged to allow
[ We claim:] [1.] An implantable prosthesis for occluding the opening of a tissue or muscle defect, said implantable prosthesis being deliverable to a surgical site through a cannula and comprising:a pliable implantable mesh fabric having a plurality of interstices constructed and arranged to allow tissue ingrowth so that said implantable mesh fabric becomes secured to neighboring tissue after implantation, said implantable mesh fabric including a body portion constructed and arranged to cover the defect opening when positioned thereagainst; anda ring of implantable material integrally attached to said body portion, said implantable ring being stiffer than said body portion of said implantable mesh fabric, said implantable mesh fabric and said integrally attached ring being rollable into a slender cylinder prior to delivery and then delivered through the cannula to the surgical site.
