Abstract: A thermography system that can be used in the vasculature of a patient, or elsewhere, with a catheter and an instrument configured to graphically display thermography data from the catheter. Sensors on the catheter may measure blood temperature, wall temperature of a body vessel or both as well as differences between blood temperature and wall temperature. Temperature differences from different locations of a patient's body vessel can be measured contemporaneously, compared and displayed on the graphical display which may be a graphic user interface in some embodiments.

Abstract: An intravascular thermography device comprising an elongate catheter having a distal guidewire port, a proximal guidewire port at a location closer to the distal end of the catheter than the proximal end, and a guidewire lumen. An expansion frame is attached to the catheter. The expansion frame is operable to expand, and has at least one temperature sensor. A capture sheath is slideably disposed about the expansion frame and operable from the proximal end of the catheter to release the expansion frame when the capture sheath is removed from the expansion frame. The capture sheath has a passage in a distal region of the capture sheath, the passage being shaped to align with the proximal guidewire port of the catheter. A registry mechanism is provided to maintain circumferential alignment between the proximal guidewire port and the passage in the distal region of the capture sheath. Methods of use are also disclosed.

Abstract: An intravascular thermography device comprising an elongate catheter having a proximal end, a distal end, a distal guidewire port in a distal region of the catheter, a proximal guidewire port at a location closer to the distal end of the catheter than the proximal end, and a lumen is described. The lumen extends between the proximal guidewire port and the distal guidewire port and is adapted to receive a guidewire. An expansion frame is attached to the catheter at a location distal to the proximal guidewire port. The expansion frame is operable between a contracted condition and an expanded condition, and has at least one temperature sensor. Methods of use are also described.

Abstract: An improved catheter capable of detecting metabolic activity within vascular anomalies is disclosed. The apparatus of the present invention includes a catheter having a distal end and a proximal end, an expandable body located at the distal end of the catheter, the expandable body comprising one or more expandable body arms, and at least one sensor integrally formed on each of the expandable body arms. The at least one sensor may include a variety of sensors, including ultrasonic sensors, flow sensors, thermal sensors, thermocouples, blood temperature sensors, electrical contact sensors, conductivity sensors, and infrared sensors.
