Appl. No.:

09/990878

Inventors:

Chris Lee - Tewksbury MA
Christine McNamara - Chelmsford MA
Ingmar Viohl - Milwaukee WI

Assignee:

Surgi-Vision, Inc. - Chelmsford MA

International Classification:

A61B 5055

US Classification:

600423, 600424, 600585, 439578

Abstract:

Connector and guidewires connectable thereto are disclosed which enable for the connection of guidewires requiring electrical connection to an external electrical source. These guidewires may be used for MRI imaging and the external source could be an MRI scanner. An embodiment of a guidewire is provided with enables for easier connection through improved dimensions and mechanical strength at the proximal end. An embodiment of a connector is provided which can attach to any guidewire or coaxial cable. These connectors provide for desirable mechanical and electrical properties while still enabling catheters and other tools to be used in conjunction with guidewires and other cables.

Abstract:

A coaxial cable may include an inner conductor, an outer conductor coaxially disposed about the inner conductor, and a proximal end sized and shaped for insertion into a connector. The proximal end may have an outer conductor contact coupled electrically to the outer conductor, and an extended section of the inner conductor that extends axially beyond the outer conductor contact. The extended section may include an inner conductor contact having an electrically conductive material disposed at least partially around the inner conductor, and an insulated area positioned to isolate electrically the outer conductive contact from the inner conductive contact, and having an electrically insulating material disposed at least partially around the inner conductor.
