  • Eccentric pressure catheter with guidewire compatibility
    Patent number: 8317715
    Abstract: There is herein described a catheter for measuring a pressure in a cardiovascular system. The catheter comprises: a guiding tube adapted for insertion into the cardiovascular system. The guiding tube defines a lumen for sliding a guidewire therethrough. The catheter further comprises a tip pressure sensor eccentrically mounted relative to the guiding tube and a signal communication means extending therefrom. The tip pressure sensor is for sensing a pressure in the cardiovascular system and the signal communicating means is for transmitting a signal indicative of the pressure to a processing device in order to obtain a pressure measurement reading.
