ABSTRACT:
The pressure monitoring guidewire comprises an elongated tube made of one piece of elastic Nickel Titanium alloy. The distal end portion of the tube has transverse openings formed through the tube wall for the entry of pressure waves into a lumen. The distal end portion of the tube which encompasses the openings, is malleable. The pressure monitoring guidewire can be formed by thermally treating the distal end portion of a guidewire formed of an elongated tube of one piece of elastic Nickel Titanium alloy having a distal end portion with transverse openings.
