During use there is a risk that a male connector for a guide wire is bent. With the present male connector () more material with high modulus of elasticity can be provided inside the male connector (), which makes the male connector () more bending resistant. The male connector () comprises a core wire (), a plurality of conductive members () spaced apart longitudinally along said core wire (), a plurality of conductors () disposed along the core wire (), each of the conductors () being connected to a respective conductive member (). The core wire () has such a shape that least one longitudinal cavity is provided, which longitudinal cavity remains substantially intact when the male connector () is bent, thereby protecting the conductors (), which are disposed in said cavity, from being damaged.

Bending resistant male connector for a guide wire

The sensor and guide wire assembly having a sensor element is inserted into the patient's body. Acoustic or electromagnetic waves are them emitted from an external source toward the sensor element. The sensor element receives the incident waves and enters into a resonating state. The characteristics of the resonance correspond to the variable or variables to be measured. A transducer is located externally from the patient's body and receives the scattered wave and transmits a resultant signal to an electronic drive and detection unit for signal analysis.

The sensor guide wire assembly having a sensor element is inserted into the patient's body. Acoustic or electromagnetic waves are then emitted from an external source toward the senor element. The sensor element receives the incident waves and enters into a resonating state. The characteristics of the resonance correspond to the variable or variables to be measured. A transducer is located externally from the patient's body and receives the scattered wave and transmits a resultant signal to an electronic drive and detection unit for signal analysis.

A male connector with a continuous surface is provided for a guide wire. The male connector includes a core wire (,), and conductive members (,) spaced apart longitudinally along the core wire (,). An insulating material (,) is disposed between the core wire (,) and the conductive members (,), the insulating material having an outer surface coextensive with outer surfaces of the conductive members (,). Conductors (,), disposed along the core wire (,), are connected to the conductive members (,). The outer surface of the insulating material and the outer surfaces of the conductive members (,) are substantially smooth.
