Patent ID: 8317799

Claim:
An assembly for delivering therapeutic material into a void in a tissue or implanted prosthetic device, said void accessed by means of a proximal opening, said assembly comprising: a. a plug having distal and proximal ends and a linear axis extending therebetween; b. one or more fluid cannulated flow tubes penetrating said plug proximal end, extending through its axial dimension and penetrating said plug distal end to thereby establish a fluid channel across said plug; c. a plug delivery structure comprising: i. a plug guide cannula having open proximal and distal ends and an axial bore extending therebetween, said bore housing said plug and one or more fluid cannulated flow tubes, constraining said plug in a radial direction, and serving as a channel for guiding said plug and cannulated flow tubes into said void; ii. a plug pusher that transmits an axial displacement force to the proximal end of said plug to dislodge said plug from said plug guide cannula into said void, wherein said plug, no longer constrained by said plug guide cannula, engages the proximal opening of said void to provide a full or partial hydraulic barrier that impedes flow from the distal side of said plug, out of said void via said proximal opening, and iii. a mechanism that coordinates the distalward axial displacement of said plug simultaneous with the distalward axial displacement of said one or more cannulated flow tubes into said void.
