Filed:

Jul 8, 1999

Appl. No.:

09/349451

Inventors:

Charles A. Gibson - Malden MA
Hab Seang - Lowell MA

Assignee:

C.R. Bard, Inc. - Murray Hill NJ

International Classification:

A61M 3700

US Classification:

604 9501, 604 9504, 604528

Abstract:

A catheter includes a pull wire which extends through two different lumen and attaches to the distal end of the catheter at an off-axis location. By tensioning the pull wire, the catheter can assume various complex curves, depending on the respective lumen through which the pull wire passes.

Charles A. Gibson - Malden MA, US

Assignee:

C.R. Bard Inc. - Murray Hill NJ

International Classification:

A61B018/14

US Classification:

606 41, 600374, 607122

Abstract:

An ablation catheter comprises a shaft and at least one ablation electrode which may be fixed or movable relative to the shaft. An insulating cap is placed over portions of the electrode which are susceptible to high current concentrations when RF energy is applied to the electrode. Typically, such portions occur in the region of abrupt surface transitions such as the edges of the electrode.

International Classification:

A61B 18/18
A61M 31/00

US Classification:

606 41, 604 9504, 607122

Abstract:

Catheters for mapping and/or ablation are disclosed. In one embodiment, the catheter comprises a handle, a flexible shaft, a tip assembly, and a cable. The handle includes an actuator and is attached, at its distal end, to the proximal end of the flexible shaft. The flexible shaft has a longitudinal axis that extends along a length of the shaft. The proximal end of the tip assembly is attached to the distal end of the shaft and includes a fixed bend of approximatley ninety degrees relative to the longitudinal axis of the shaft. The distal end of the tip assembly includes an arcuate curve having a diameter. The arcuate curve is oriented in a plane that is approximatley perpendicular to the longitudinal axis of the shaft. The cable is attached to the actuator and the distal end of the tip assembly, and extends through the shaft. The cable is adapted to change the diameter of the arcuate curve in response to movement of the actuator.

A61M 25/00

US Classification:

604 9504, 604525, 604 9501

Abstract:

Methods and apparatuses for manipulating an elongated flexible shaft of a catheter provide case and reliability of positioning electrodes against or near tissue. Dual-bend flexible distal tips () may be used in combination with flat wires. In some embodiments, flat wires which are free to rotate upon initial bending of shaft segments are employed. In some embodiments, one or more transition segments () are used to relocate the satellite lumen-to-main lumen transition of pull wires () away from a change in shaft stiffness.

Assignee:

Bard Electrophysiology - Murray Hill NJ

International Classification:

A61B 18/14

US Classification:

606 41

Abstract:

Apparatus for irrigating an electrode of a catheter are disclosed. Among other things, a catheter is disclosed that comprises a shaft portion including a fluid passage to conduct fluid, an electrode coupled to a distal end of the shaft portion, and a handle portion coupled to a proximal end of the shaft portion. A portion of the fluid passage defines an opening in the shaft portion. The opening is constructed and arranged such that when fluid is conducted through the fluid passage, at least some of the fluid will contact the electrode after passing through the opening in the shaft portion.
