Cardiac mapping probe
First Claim
1. A cardiac mapping probe comprising:
- a lead body having a distal end, a distal end portion and a proximal end and comprising a tubular sheath, a head with a pad having a flat surface mounted at said distal end of said lead body, said pad being located on a side of said tubular sheath such that said flat surface of said pad faces radially outwardly from an elongate axis of said lead body, at least two electrodes on said flat surface of said pad, at least two wire conductors within said tubular sheath and extending the length thereof and being connected to said electrodes, and pliable, moldable means in the form of a ductile metal rod which has a coating thereon to prevent contamination of blood or body tissue with the metal of the rod, which is stiff but bendable, which is rounded at each end to provide said rod without sharp edges and which is mounted within said distal end portion of said lead body for providing said distal end portion with the capability of being formed into various shapes whereby it can be molded and formed into any desired configuration for facilitating holding of said distal end portion and placement of said at least two electrodes against a heart wall and can hold such configuration until remolded and reformed into another configuration.

Abstract
The cardiac mapping probe has a soft lead body with a distal end portion containing a pliable, moldable and formable core rod therein. The rod is received within a tubular sheath of the lead body which also includes four insulated wire conductors within the sheath. A head is formed at the distal end of the sheath and has a pad with a flat surface on the underside thereof. Four electrodes are mounted on the flat surface and connected to the wire conductors. Such probe will facilitate placement of the pad flat surface against a section of a heart wall to be mapped and will hold that shape until reconfigured to another shape. Part of the configured, molded shape can provide a handle formation for facilitating gripping and manipulation of the mapping probe.
