Patent ID: 7160292

Claim:
A modular needle kit for ablation through a puncture site, comprising: a delivery needle insertable through the puncture site, said delivery needle having an open proximal end and an open distal end with a lumen extending therebetween; an ablation needle adapted for ablating tissue along a length of the ablation needle, said ablation needle comprising a transmission line and a microwave antenna electrically coupled to said transmission line, wherein said microwave antenna is insertable through said open proximal end of said delivery needle and extends beyond said distal end of said delivery needle when said ablation needle is distally displaced within said lumen of said delivery needle, and wherein said ablation needle is further adapted to ablate tissue surrounding the microwave antenna and transmission line; and a positional connector adapted to detachably couple said ablation needle in a fixed positional relationship with respect to said delivery needle, the positional connector including a first connector provided on the delivery needle and a second connector, selectively matable with the first connector, provided on the ablation needle.
