TIP ASSEMBLY FOR MRI-COMPATIBLE MEDICAL DEVICES AND MRI-COMPATIBLE MEDICAL DEVICES INCORPORATING SAME

摘要

An MRI-compatible tip assembly for an MRI-compatible medical device includes a first tubular member, a second tubular member, a ring electrode, and a tip electrode. The tip electrode proximal end is secured to the first tubular member distal end. The second tubular member distal end is inserted through the ring electrode and is secured to the first tubular member proximal end. When assembled, the tip assembly is a substantially rigid structure. Each tubular member has a recessed portion for a tracking coil.
