Abstract

The pressure monitoring guide wire (1) comprises an elongated tube (1) made of one piece of elastic Nickel Titanium alloy. The distal end portion (3) of tube (1) has transverse openings (6) formed through wall (5) of tube (1) for the entry of pressure waves into lumen (4).
The distal end portion (3) of tube (1) which encompasses the openings (6), is malleable. A thermal treatment is made to the distal end portion (3) of a guide wire formed of an elongated tube (1) of one piece of elastic Nickel Titanium alloy having a distal end portion (3) with transverse openings (6).
