摘要： A pressure sensing device is provided that can monitor and measure pressure at two points in a vessel or artery without moving the outer sheath or catheter of the device. The outer sheath or catheter includes two spaced apart openings that may be positioned in a vessel or artery on opposing sides of an occlusion. The device also includes an inner elongated tube with at least one opening. The inner elongated tube is slidable with respect to the outer sheath or catheter thereby permitting the opening of the elongated tube to be moved into selective registration with one of the openings of the outer sheath. A pressure measurement may be taken through one of the openings in the outer sheath by aligning the opening of the elongated tube with said opening and, then, a second pressure reading may be taken by sliding the elongated tube within the outer sheath so that the opening of the elongated tube is in registry with the other opening of the tubular sheath. As a result, pressure measurements at two points in a vessel or artery may be taken without moving the outer sheath or catheter.

摘要： A pressure-sensing guidewire assembly with improved stiffness and torquability is disclosed. The guidewire assembly includes an elongated tubular member having a lumen extending therethrough. The lumen receives a torque enhancing mandrel that adds stiffness and torquability to the elongated tubular member. The torque enhancing member and elongated tubular member may have an atraumatic spring tip.

摘要： An extension system for a pressure-sensing guidewire is disclosed. The guidewire includes an elongated tubular member having a proximal end, a distal end and a lumen extending between the proximal and distal ends. The guidewire also includes at least one opening disposed adjacent the distal end of the tubular member for providing fluid communication to the lumen. The system also includes an elongated extension member that is detachably connected to the proximal end of the tubular member. The system enables a catheter to be inserted over a pressure-sensing guidewire without removing the pressure-sensing guidewire from a patient.
摘要翻译：公开了用于压力传感导丝的延伸系统。导丝包括细长的管状构件，其具有近端，远端和在近端和远端之间延伸的内腔。导丝还包括邻近管状构件的远端设置的至少一个开口，用于提供与内腔的流体连通。该系统还包括细长的延伸构件，其可拆卸地连接到管状构件的近端。该系统使得导管能够插入压力感测导丝上而不从患者移除压力感测导丝。
