Abstract: A system for monitoring the temperature of a patient undergoing an examination in strong magnetic field, such as that created by an MRI machine. The system includes a temperature sensor composed of a high accuracy temperature probe that is coupled to an electronics module by an RF current reduction network. The temperature sensor is excited by a constant current provided on two of the four leads comprising the RF current reduction network. The remaining two leads connect to an instrumentation amplifier. All of the circuitry is located within a Faraday housing, and all connections made between the sensor and the electronics module pass through RF filters mounted in the Faraday housing, allowing the electronics module to be positioned within the strong magnetic field.

Abstract: A method for treating a blood vessel in a wall forming a gastrointestinal tract of a body of a mammal. At least one nonaqueous solution is introduced from the gastrointestinal tract into the vessel. A nonbiodegradable solid is formed in the vessel in the vicinity of a portion of the vessel from the least one nonaqueous solution to create an occlusion in the vessel and thus terminate blood flow to the vessel distal of the occlusion.
