Catheter for NMR investigation has a folding out coil probe that can be positioned accurately within large volume body cavities after insertion through narrow vessels and cavities

摘要

Catheter comprises a catheter body (1) made of flexible material with a measurement tip, an unfolding NMR probe (2) and a guide channel for insertion of a guide element for mechanical stabilization of the catheter and or a cleaning or suction channel, whereby a control channel with a control element is designed to control the positioning of the measurement tip from the distal end of the catheter body.
