Abstract

A flexible elongate member such as a pressure guide wire (1000) includes an electrical device such as a pressure sensor (1002). The pressure sensor (1002) is electrically connected to conductive bands (304), (306) and (308) located on electrical connector (300). The electrical connector is attached to core wire (602) and shaft or hypotube (704). The use of electrical connector (300) helps minimize the assembly time of pressure guide wire (1000), as well as minimize some of the assembly problems associated with prior art designs such as pressure guide wire (100).

Claims

1. A device for insertion into humans or animals, comprising;

a flexible elongate member having an outer diameter of 0.018 inches or less;

an electrical device coupled to the flexible elongate member,

an electrical conductor, and

a circuit carrier formed by a tubular member having at least one conductive band on the outer surface of the tubular member,

wherein the electrical conductor electrically connects the electrical device to the at least one conductive band.

2. The device of claim 1, wherein the electrical conductor is a runner.

3. The device of claim 1, wherein the electrical conductor is a wire operably coupled to a runner.

4. The device of claim 1, wherein the conductive band does not extend around the entire circumference of the tubular member.

5. The device of claim 1, wherein the circuit carrier is cut axially.

6. The device of claim 1, wherein the electrical device is a pressure sensor.

7. The device of claim 1, wherein the electrical device is a flow sensor.

8. The device of claim 1, wherein the tubular member is formed of polyimide.

9. The device of claim 1, wherein the conductive band comprises a metal.

10. The device of claim 3, wherein the electrical conductor is coupled to the runner by soldering.

11. The device of claim 1, where the flexible elongate member comprises proximal and distal ends, and the electrical device is located in proximity to the distal end.

12. The device of claim 1 wherein the circuit carrier is an electrical connector.

13. The device of claim 1 wherein the tubular member is formed from semi-stiff material.
