MRI COMPATIBLE CABLE
First Claim
1. A cable construct comprising:
- an elongate body having a proximal end and a distal end, said elongate body defining a lumen therewithin, the distal end arranged and configured to be operably coupled to a patient and the proximal end operably coupled to a medical device or peripheral equipment; and
at least one circuit housed within said elongate body and comprising one or more wires, said one or more wires forming at least one non-resonant filter and at least one resonant LC filter, said resonant LC filter positioned proximate the distal end of said elongate body.

Abstract
An MRI compatible cable construct is provided. The cable is adapted to be used with a medical device in direct electrical contact with a patient. Each cable or cable set includes a plurality of filter components. The filter component comprises at least two filter components. One filter component may be a resonant filter at a distal end that resolves the issue of insufficient attenuation by effectively blocking the RF induced current on the cable from exiting the cable at the distal. The second filter component may comprise one or more non-resonant filter(s) or inductors positioned along the length of the cable that resolve(s) the issue of excessive heating of the resonant LC filter by significantly attenuating the current induced on the cable before it reaches the resonant LC filter.
