Embodiment Construction

[0024] FIG. 1 shows a cable assembly 10 having a connector end 12 , a sensor end 14 and a connection flex cable 16 . The connector end and sensor end shown are examples of components that may be connected to the cable 16 . In this example, the connector end includes a circuit board 20 with a connector 22 for connection to electronics such as an ultrasound imaging machine. The connector end includes a connector housing 24 and a strain relief 26 surrounding the cable end. At the opposite end, an ultrasonic sensor 30 is connected to the cable.

[0025] The cable 16 includes numerous fine coaxial shielded wires 32 . As also shown in FIG. 2, the wires are arranged in groups 33, wherein each group has a ribbonized ribbon portion 34 at each end and an extended fan-out portion 36, wherein the fan-out portion 36 is at the end of the ribbon-like portion. between and for substantially the entire length of the cable. Each ribbon portion includes a side-by-side arrangement of adhering ...

Abstract

A cable assembly has a number of wires, each with opposed first and second ends. The wires have intermediate portions between the first and second ends, and the intermediate portions are detached from each other. A conductive shield loosely encompasses all the wires, and the shield and wires are received within a resilient catheter sheath. A medical imaging transducer may be connected to one end of the wires, and the wires may be ribbonized at the other end. The transducer may be an ultrasound or other imaging transducer, and may be received in the catheter.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of U.S. Patent Application Serial No. 10 / 290,590 filed in the USPTO on November 7, 2002, which in turn was filed in the USPTO on December 18, 2001 Continuation-in-Part of US Patent Application No. 10 / 025,096, the contents of which are incorporated herein in their entirety. technical field [0003] This invention relates to multiconductor cables, and more particularly, the present invention relates to small gauge conductors for use in conjunction with catheters used in medical procedures. Background technique [0004] Certain demanding applications require miniaturized multi-conductor cable assemblies. Very thin conductors are used in order to avoid unnecessarily bulky cables when many conductors are required. To limit electrical noise and interference, coaxial wires with shields are often used for those conductors. An insulating sheath surrounds the center conductor and ele...
