First Claim
1. A self-contained closed implant system for the formation of a prosthesis device percutaneously within a nucleus cavity formed in an intervertebral disc at an in situ implant site, comprising:
- a single lumen working cannula, said single lumen working cannula configured to be docked against an outer surface area of an annulus surrounding the nucleus cavity, wherein said single lumen working cannula has arranged at about its proximal end a collar assembly to facilitate matingly engaging the single lumen working cannula with said closed insertion assembly;
a closed sizing assembly configured to be partially received within said single lumen working cannula for carrying at a distal end thereof an elastically deformable mock implant member to the in situ implant site to facilitate determining, without fluid evacuation from the closed implant system, a known volume of filler material to substantially fill the volume of the nucleus cavity;
a closed insertion assembly configured to be partially received within said single lumen working cannula in place and stead of said closed sizing assembly for protectively carrying an elastically deformable implant member to the in situ implant site to facilitate its filling with said known volume of filler material;
a closed dispensing assembly configured to be partially received within said single lumen working cannula and removably coupled to said closed insertion assembly without relative rotational motion therebetween to facilitate the filling of the elastically deformable implant member with said known volume of filler material without fluid evacuation from the closed implant system; and
wherein the closed dispensing assembly includes a distal end magnetic mount for removably coupling the closed dispensing assembly to the single lumen working cannula and a proximal end magnetic mount for removably coupling the closed dispensing assembly to the closed sizing assembly to facilitate determining, without fluid evacuation from the closed implant stem the known volume of filler material to substantially fill the volume of the nucleus cavity and for removably coupling the dispensing assembly to the closed insertion assembly in place and stead of the closed sizing assembly to facilitate the filling of the elastically deformable implant member with the known volume of filler material without fluid evacuation from the closed implant system to help reduce tissue trauma to a patient by obviating relative rotational coupling motions.

Abstract
A tissue prosthesis insertion system includes a first assembly comprising a plurality of nested tubes, one of the tubes being a carrier tube which, in use, receives a component of a tissue prosthesis at a distal end of the carrier tube. A magnetic mount is carried at a proximal end of the first assembly. A second assembly is removably attachable to the first assembly. An attachment device is carried at a distal end of the second assembly, the attachment device being responsive to the magnetic mount of the first assembly, the magnetic mount and the attachment device carrying complementary engaging formations to facilitate hermetic sealing between the magnetic mount and the attachment device.
