Abstract

A guide wire assembly comprising a guide wire with first and second conductors which extend along the length thereof. The guide wire also comprises a flexible cable having first and second conductors which extend along the length thereof. The connector assembly includes a male connector with a sleeve and a conductive core which is mounted in the sleeve. An insulator is mounted in the sleeve and insulates the conductive core from the sleeve. A conductive band is carried by the insulator and is spaced from the sleeve. The first and second conductors are disposed within the sleeve. The first connector is connected to the conductive core and the second conductor is connected to the conductive band. The connector assembly includes a female connector that has an inner conductive grip which has a cylindrical recess for receiving the conductive core and an outer conductive grip that has a cylindrical band which engages the portion extending forwardly of the inner conductive grip. An insulator is disposed between the inner and outer conductive grips. An insulating case is mounted on the outer conductive grip. First and second conductors are disposed within the case.

Claims

1. An apparatus comprising a catheter having a passage extending therethrough, a guide wire extending through the catheter, the guide wire carrying an electrical device, first and second conductors extending the length of the guide wire, an electronic device, a cable connected to the electronic device and having first and second conductors and interconnecting means connecting the first and second conductors of the cable to the first and second conductors in the guide wire, said interconnecting means including means permitting interconnection, disconnection and free rotation between the first and second conductors of the guide wire and the first and second conductors of the cable.

2. Apparatus as in claim 1 together with means carried by the distal extremity of the guide wire for directing ultrasonic energy from the guide wire in a direction which is at an angle with respect to the longitudinal axis of the guide wire.

3. Apparatus as in claim 1 wherein said interconnecting means includes slip ring means for permitting rotation of the guide wire with respect to the cable.

4. Apparatus as in claim 3 together with means connected to the slip ring means for permitting free rotation of the guide wire while restraining longitudinal movement of the guide wire within the interconnection means.

5. Apparatus as in claim 4 wherein said slip ring means includes an insulating member, first and second cylindrical conductive members carried by the insulating member and spaced apart longitudinally of the insulating member, and spring-like finger members yieldably engaging the cylindrical conductive members.

6. Apparatus as in claim 4 wherein said interconnection means is secured to the guide wire and is rotatable with the guide wire whereby the interconnecting means can be utilized as a torquing device for the guide wire.

7. Apparatus as in claim 5 wherein the cylindrical conductive members are electrically connected to the first and second conductors of the guide wire and wherein the spring-like finger members are electrically connected to the first and second conductors of the cable.

8. Apparatus as in claim 7 wherein said guide wire is provided with a core which extends substantially the entire length thereof and wherein the first and second conductive cylindrical members are electrically bonded to the first and second conductors of the guide wire and wherein the first and second conductors of the cable are connected to the spring-like members.

9. An apparatus comprising a catheter having a passage extending therethrough, a guide wire extending through the catheter, the guide wire carrying an electrical device, first and second conductors extending the length of the guide wire, an electronic device, a cable connected to the electronic device and having first and second conductors, interconnecting means connecting the first and second conductors of the cable to the first and second conductors in the guide wire, said interconnecting means including means permitting interconnection and disconnection between the first and second conductors of the guide wire and the first and second conductors of the cable, said interconnecting means including slip ring means for permitting rotation of the guide wire with respect to the cable, means connected to the slip ring means for permitting free rotation of the guide wire while restraining longitudinal movement of the guide wire within the interconnection means and a torquing device secured to the guide wire for rotating the guide wire.

10. An apparatus comprising a catheter having a passage extending therethrough, a guide wire extending through the catheter, the guide wire carrying an electrical device, first and second conductors extending the length of the guide wire, an electronic device, a cable connected to the electronic device and having first and second conductors, interconnecting means connecting the first and second conductors of the cable to the first and second conductors in the guide wire, said interconnecting means including means permitting interconnection and disconnection between the first and second conductors of the guide wire and the first and second conductors of the cable, said interconnecting means including slip ring means for permitting rotation of the guide wire wire with respect to the cable, means connected to the slip ring means for permitting free rotation of the guide wire while restraining longitudinal movement of the guide wire within the interconnection means and a torquing device secured to the guide wire which is spaced apart from the interconnection means, said interconnection means serving as a rotary connector.
