Abstract
The present invention relates to a reinforced magnetic resonance imaging catheter. The catheter comprises an elongated body having at least one lumen extending therethrough. The elongated body also includes a proximal end, a distal end, and circumference, a longitudinal axis running between the proximal and distal ends, and a coaxial layer that incorporates at least one elongated ceramic member. An antenna is operably disposed proximate the distal end the elongated body.

A reinforced magnetic resonance imaging catheter, comprising:
- an elongated body having at least one lumen extending therethrough, the elongated body further comprising a proximal end, a distal end, a circumference, a longitudinal axis running between said proximal and distal ends, and a coaxial layer that incorporates at least one elongated ceramic member;
- and
- an antenna operably disposed proximate the distal end of the elongated body.
An elongated medical device for intravascular manipulation during magnetic resonance imaging of body tissue, comprising:
- an elongated body;
- an antenna operably disposed proximate the distal end of the elongated body;
- and
- a reinforcement mechanism disposed about a portion of said elongated body, the reinforcement mechanism comprising at least one elongated ceramic member.
A reinforcement member for reinforcing an elongated intravascular magnetic resonance imaging device, the reinforcement member comprising:
- an elongated ceramic fiber comprising applied surface scratches;
- and
- a coating disposed about the elongated ceramic fiber, substantially filling the applied surface scratches, enabling an enhanced flexibility wherein the ceramic fiber can be bent without breaking.
