Abstract
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.
Claims28
A tip assembly for an MRI-compatible medical device, the tip assembly comprising:
- a first tubular member comprising opposite proximal and distal ends and a circumferential recessed portion located therebetween;
- and
- a second tubular member comprising opposite proximal and distal ends and a circumferential recessed portion located therebetween;
- wherein the second tubular member distal end is secured to the first tubular member proximal end, wherein each recessed portion comprises opposing ends, and wherein a pair of apertures are formed in each recessed portion, each aperture proximate a respective end of the recessed portion.

An MRI-compatible medical device, comprising:
- an elongated flexible shaft having a distal end portion, and an opposite proximal end portion;
- and
- a substantially rigid tip assembly at the flexible shaft distal end portion, the tip assembly comprising:
- a first tubular member comprising opposite proximal and distal ends and a circumferential recessed portion located therebetween;
- and
- a second tubular member comprising opposite proximal and distal ends and a circumferential recessed portion located therebetween;
- wherein the second tubular member distal end is secured to the first tubular member proximal end, wherein each recessed portion comprises opposing ends, and wherein a pair of apertures are formed in each recessed portion, each aperture proximate a respective end of the recessed portion.
(canceled)
A tip assembly for an MRI-compatible medical device, the tip assembly comprising:
- a tubular member comprising opposite proximal and distal ends and a pair of spaced-apart circumferential recessed portions located between the proximal and distal ends;
- wherein each recessed portion comprises opposing ends, and wherein a pair of apertures are formed in each recessed portion, each aperture proximate a respective end of the recessed portion.
(canceled)
An MRI-compatible medical device, comprising:
- an elongated flexible shaft having a distal end portion, and an opposite proximal end portion;
- and
- a substantially rigid tip assembly at the flexible shaft distal end portion, the tip assembly comprising:
- a tubular member comprising opposite proximal and distal ends and a pair of spaced-apart circumferential recessed portions located between the proximal and distal ends;
- wherein each recessed portion comprises opposing ends, and wherein a pair of apertures are formed in each recessed portion, each aperture proximate a respective end of the recessed portion.
