Abstract:
1. A catheter for magnetic resonance-supported interventional procedures in an environment that subjects the catheter to radio-frequency pulses generated by a magnetic resonance imaging system, said catheter comprising a tubular catheter wall having an interior surface that defines an interior of said catheter in which an electric cable is connected that connects a first electric component mounted at a first catheter end with a second electric component mounted at a second catheter end, said electric cable being susceptible to having RF current therein due to interaction of said electric cable with said RF pulses, and said electric cable being coiled around a coil axis in at least one coiled section thereof with a coiling configured to produce an inductance that absorbs said RF current, said at least one coiled section having a coiled section exterior that is radially outwardly spaced from said coil axis and radially inwardly spaced from said interior surface and said catheter comprising a mechanism operable to bend at least one of said first and second catheter ends, said mechanism being selected from the group consisting of a Bowden cable and fluid lines forming a fluid muscle, and wherein a portion of said mechanism operable to bend one of said first and second catheter ends is located in a space between said coiled section exterior and said interior surface of said catheter.
