Abstract
A medical device that inhibits distortion of medical resonance images taken of the device. In particular, various structures are utilized to allow visibility proximate, and inside of, a tubular member, such as a stent. In one embodiment, the stent is constructed such that any closed path encircling at least a circumference of the stent will pass through at least two materials to reduce or eliminate electrical loops formed in the stent.
Claims21
A medical device for use within a body cavity, the medical device having a visualization region in which visualization using magnetic resonance imaging (MRI) is desired, the medical device comprising:
- structural material defining a primary structure having a wall with openings therein and a periphery, the structural material being configured such that any closed path, in the visualization region, extending about at least one of the periphery or an opening in the wall, passes through at least two materials, wherein at least one of the materials comprises a substantially low magnetic susceptibility material.
