Filed:

Dec 30, 2005

Appl. No.:

11/322591

Inventors:

Eduardo Jimenez - Paramount CA, US

Assignee:

Biosense Webster, Inc. - Diamond Bar CA

International Classification:

A61B 18/14

US Classification:

606 34, 606 41

Abstract:

The present invention is directed to a system, a method and a catheter that provide improved ablation capabilities and improved energy efficiency by selectively energizing catheter electrodes on the basis of impedance measurements. In particular, the invention is directed to the selective energization of catheter radial electrodes that together with a tip electrode form a generally continuous tissue contact surface, wherein the selection is made on the basis of impedance measurement as an indication of the amount of tissue contact of each radial electrode.

International Classification:

A61B 5/05

US Classification:

600391

Abstract:

An patch and sensor assembly for use in an EP mapping system has two portions: a reusable portion and a disposable portion. The reusable portion houses the biosensors used in magnetic based location and mapping systems and the electrical lead necessary to communicate between the biosensor and the mapping system. The reusable portion may also contain a portion of the electrode necessary to receive electrical signals from the body of the patient. The disposable portion of the patch and sensor assembly contains an adhesive covered flexible patch having at least a portion of the electrode used to receive electrical signals form the body of the patient and may contain the electrical lead necessary to communicate such an electrical signal to the mapping system. The disposable portion contains a receptacle adapted to receive and mechanically secure the reusable portion to the disposable portion of the assembly. Such a patch and sensor assembly is useful in hybrid magnetic and impedance based location and mapping systems such as those used in electrophysiology.

International Classification:

A61B 18/14

US Classification:

606 42

Abstract:

An electrophysiologic catheter with an improved control handle is provided. The catheter includes a heat transfer assembly to better dissipate heat in the control handle. The heat transfer assembly includes a pump, a reservoir containing a coolant, a heat transfer member, and a coolant transport network transporting coolant between at least the reservoir and the heat transfer member. In one embodiment, the heat transfer member is located within the control handle as a heat exchanger on the circuit board to receive the coolant for transferring heat from the integrated circuits to the coolant. In another embodiment, the heat transfer member is located on the circuit board directly surrounding the integrated circuits to internally cool the integrated circuit within the control handle. A second heat transfer member is located outside of the control handle as a heat exchanger.

International Classification:

A61B 18/14

US Classification:

606 41

Abstract:

A catheter includes an elongated body, a distal assembly with a shape-memory member defining a generally helical form, and a control handle. The control handle may be adapted to actuate a deflection puller wire for deflecting a portion of the elongated body and a contraction wire for contracting the generally helical form. The generally helical form carries irrigated ablation ring electrodes. A nitinol support member with shape memory extends through the distal assembly and into the elongated body to provide the helical form. The support member may have a varying stiffness along its length, for example, a decreasing stiffness toward a distal end of the support member. The support member can also be hollow so that it can receive a mandrel whose stiffness is greater than that of the support member.

International Classification:

A61B 5/00
A61B 5/042
A61B 18/14

Abstract:

A catheter having a distal assembly with multiple spines with proximal ends affixed to the catheter and free distal ends. The spines have different lengths so distal ends of the spines trace different circumferences along an inner tissue surface of a tubular region to minimize risk of vein stenosis. The spine lengths can be configured so that the distal ends trace a helical pattern. The distal assembly may have a plunger which deflects the spines when moved longitudinally relative to the distal assembly. The catheter may include a second distal assembly distal of a first distal assembly wherein the first and second distal assemblies are separated by a fixed distanced or an adjustable distance.
