Ablation cable assemblies and a method of manufacturing the same
First Claim
Patent Images
1. A method of manufacturing a cable assembly, the method comprising:
- trimming a proximal end of a dielectric of a coaxial cable extending from a proximal end of a rigid tube to expose a proximal portion of an inner conductor;
exposing a length of the inner conductor at a distal portion of the coaxial cable;
forming a radiating portion about the exposed length of the inner conductor including shrinking a first dielectric tube over the inner conductor with a proximal end of the first dielectric tube abutting a distal end of the dielectric; and
leaving a conductive braid exposed between the rigid tube and the radiating portion such that fluid may impregnate the conductive braid, the conductive braid covering the dielectric of the coaxial cable between the rigid tube and the distal end of the dielectric.

Abstract
A cable assembly includes a rigid portion, a flexible central portion, and a radiating portion. The rigid portion is configured to couple to a source of electrosurgical energy and to prevent fluid ingress towards the source of electrosurgical energy. The flexible central portion extends from the rigid portion and includes an inner conductor, a dielectric disposed about the inner conductor, and a conductive braid disposed about the dielectric. The radiating portion extends from the central portion and is configured to deliver electrosurgical energy to tissue.

3. A method of manufacturing a cable assembly, the method comprising:
-
trimming a proximal end of a dielectric of a coaxial cable extending from a proximal end of a rigid tube to expose a proximal portion of an inner conductor; exposing a length of the inner conductor at a distal portion of the coaxial cable; forming a radiating portion about the exposed length of the inner conductor including; shrinking a first dielectric tube over the inner conductor with a proximal end of the first dielectric tube abutting a distal end of the dielectric; shrinking a second dielectric tube over the distal end of the dielectric, the first dielectric tube, and a portion of the exposed inner conductor; and extending a conductive braid over first and second dielectric tubes, tucking the conductive braid into a joint between the distal end of the dielectric and the proximal end of the first dielectric tube to form a first discrete step down, and tucking the conductive braid about the distal end of the first dielectric tube to form a second discrete step down; and leaving a conductive braid exposed between the rigid tube and the radiating portion such that fluid may impregnate the conductive braid. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12)
