Abstract:
1. An elongate intrabody MRI-compatible medical device, comprising: a rigid stylet body having opposing distal and proximal ends with a wall enclosing at least one cavity extending therebetween, wherein the stylet body has first and second laterally spaced apart and opposing external longitudinally extending recessed surfaces and at least one pair of transversely spaced apart apertures extending through the wall; and at least one conductor having a length that extends through the cavity, then exits the cavity to define a plurality of external loops extending between the distal end of the stylet body and the pair of transversely spaced apart apertures, wherein first and second legs of the external loops snugly abut a corresponding one of the first and second recessed surfaces of the stylet body to thereby cooperate with the stylet body to define a substantially cylindrical shape, and wherein the at least one conductor with the external loops is configured to act as an MRI antenna, wherein the at least one conductor with the external loops is configured so that the at least one conductor either extends through the cavity of the stylet body then (a) first exits one of the transversely spaced apart apertures of the stylet body and extends outside the cavity of the stylet body against the first recessed surface, then around the distal end of the stylet body to turn and reside against the second recessed surface, then extends through both transversely spaced apart apertures or (b) first exits the distal end of the stylet body, turns back toward the pair of transversely spaced apart apertures outside the cavity of the stylet body against one of the first or second recessed surfaces, then extends through the pair of transversely spaced apart apertures to exit and extend against the other of the first or second recessed surfaces.
