摘要 |
A guide (101) wire for use in measuring a characteristic of liquid flow in a vessel includes a flexible elongate tubular element (102) having proximal and distal extremities. A core wire (103) extends through at least a portion of the flexible elongate element and has a tapered distal extremity (104) extending beyond the distal extremity of the tubular element. A coil (106) extends over and beyond the distal extremity of the core wire. A transducer (111) is secured to the distal extremity (109) of the coil. First and second conductor means (118) are carried by the tubular element and are connected to the transducer, extending to the distal extremity (119) of the tubular element (102). Means (107) are provided for bonding the tubular element (102) to the core wire (103) and the coil (106) to the tubular element (102) and to the core wire so that torsional forces applied to the tubular element are supplied to the coil spring. |
