Implantable prosthesis and method and apparatus for loading and delivering an implantable prosthesis
First Claim
1. An apparatus for loading and delivering a pliable implantable prosthesis into a trocar cannula having a lumen, the pliable implantable prosthesis having a first configuration larger than the lumen of the trocar cannula and being formable into a second configuration which is smaller than the lumen of the trocar cannula, said apparatus comprising:
- an elongated body having a lumen extending therethrough and an elongated slot extending radially from said lumen through a surface of said elongated body, said elongated slot adapted to admit the implantable prosthesis in the first configuration and said elongated body lumen adapted to receive and maintain the implantable prosthesis in the second configuration;
a distal end of said elongated body constructed and arranged for receipt in the lumen of the trocar cannula.

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.

21. A method of loading and delivering an implantable prosthesis to a trocar cannula having a lumen, comprising:
-
providing an elongated body having a lumen extending therethrough and an elongated slot extending radially from the elongated body lumen through a surface of the elongated body, the elongated slot adapted to admit the implantable prosthesis in an expanded configuration which is larger than the trocar cannula lumen and the elongated body lumen being adapted to receive and maintain the implantable prosthesis in a reduced configuration which is smaller than the trocar cannula lumen, a distal end of the elongated body constructed and arranged for receipt in the lumen of the trocar cannula; admitting the implantable prosthesis in the expanded configuration through the elongated slot into the elongated body lumen where it is maintained in the reduced configuration; inserting the distal end of the elongated body in the lumen of the trocar cannula; advancing the implantable prosthesis in the reduced configuration through the elongated body lumen and into the trocar cannula lumen.
