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.

La présente invention concerne un cathéter permettant de mesurer une pression dans un système cardiovasculaire. Le cathéter comporte : un tube de guidage apte à être introduit dans le système cardiovasculaire. Le tube de guidage définit une lumière pour y coulisser un fil-guide. Le cathéter comporte également un capteur de pression d'extrémité monté excentré par rapport au tube de guidage et un moyen de communication de signaux s'étendant depuis celui-ci. Le capteur de pression d'extrémité sert à détecter une pression dans le système cardiovasculaire et le moyen de communication de signaux sert à transmettre un signal indiquant la pression à un dispositif de traitement afin d'obtenir un relevé de mesure de pression.
