Abstract
The present invention provides for an improved combination sensor tip that includes an ultrasound transducer and a pressure sensor both disposed at or in close proximity to the distal end of the combination sensor tip. The present invention also provides for an improved connector to couple a guide wire to a physiology monitor that reduces torsional resistance when maneuvering the guide wire.

31. A system comprising:
-
a flexible elongate member having a proximal portion, a distal portion, and an outer diameter less than or equal to 0.018 inches, a pressure sensor secured to the distal portion of the elongate member, and a sensor for measuring a blood flow characteristic other than blood pressure secured to the distal portion of the elongate member, wherein the separation between the pressure sensor and the sensor for measuring a blood flow characteristic other than blood pressure is less than 3 cm, wherein the pressure sensor and the sensor for measuring a blood flow characteristic other than pressure are in electrical communication with a plurality of conductive portions of a male connector adjacent the proximal portion of the flexible elongate member; and a female connector configured to receive the male connector of the flexible elongate member, the female connector including a plurality of conductive portions configured to interface with the plurality of conductive portions of the male connector to facilitate communication of signals from the pressure sensor and the sensor for measuring a blood flow characteristic other than pressure to a processing system. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. A system comprising:
-
a flexible elongate member having a proximal portion, a distal portion, and an outer diameter less than or equal to 0.018 inches, a pressure sensor secured to the distal portion of the elongate member, and a sensor for measuring a blood flow characteristic other than blood pressure secured to the distal portion of the elongate member, wherein the separation between the pressure sensor and the sensor for measuring a blood flow characteristic other than blood pressure is less than 3 cm, wherein the pressure sensor and the sensor for measuring a blood flow characteristic other than pressure are in electrical communication with a plurality of conductive bands of a male connector adjacent the proximal portion of the flexible elongate member; and a female connector configured to receive the male connector of the flexible elongate member, the female connector including a plurality of electrical contacts configured to interface with the plurality of conductive bands of the male connector to facilitate communication of signals from the pressure sensor and the sensor for measuring a blood flow characteristic other than pressure to a processing system, wherein the female connector includes an unlocked position for receiving and releasing the male connector of the flexible elongate member and a locked position for securing the male connector within the female connector. - View Dependent Claims (45, 46, 47, 48, 49, 50)
