CATHETER ASSEMBLY WITH DISTAL END INDUCTIVE COUPLER AND EMBEDDED TRANSMISSION LINE

摘要

A catheter assembly (10) includes an elongate catheter body (12) having a proximal end, and a distal end with a drive cable disposed therein, the drive cable having a proximal end, and a distal end, and rotatable relative to the catheter body. A first electro-magnetic element (20) is disposed proximate the distal end of the catheter, and a second electro-magnetic element (22) is disposed proximate the distal end of the drive cable, and in electrical communication with an operative element mounted at the end of the drive cable with the first, and second electro-magnetic elements forming an inductive coupler (14). The catheter assembly can include various other distal operative elements, which are in communication with corresponding proximal operative elements via transmission lines embedded within the wall of the catheter body.
