US Patent:

7270673, Sep 18, 2007

Filed:

Dec 31, 2003

Appl. No.:

10/750541

Inventors:

Carl Yee - San Diego CA, US
Ricardo Roman - San Diego CA, US
Brandon Schwab - San Diego CA, US

Assignee:

Boston Scientific Scimed, Inc. - Maple Grove MN

International Classification:

A61B 17/22

US Classification:

606159

Abstract:

A microsurgical balloon, with at least one incising component mounted to the surface of the balloon, includes a protective pad to prevent the outer surface of the incising component from coming into contact with and damaging the balloon surface. In particular, the protective pad is positioned on the outer surface of the balloon substantially parallel to and juxtaposed with the incising component. When the balloon is in a deflated configuration, either for insertion into the vasculature system or removal from the patient, the protective pad engages the outer surface of the incising component thereby protecting the balloon from being punctured or damaged by the incising component. The protective pad may be bonded to the outer surface of the balloon, or it may be an integral part of a homogeneous balloon structure.

International Classification:

A61B 18/14

US Classification:

606 41

Abstract:

Devices, systems and methods are disclosed for the mapping of electrical signals and the ablation of tissue. Embodiments include an ablation catheter that has an array of ablation elements attached to a deployable carrier assembly. The carrier assembly can be transformed from a compact, linear configuration to a helical configuration, such as to map and ablate pulmonary vein ostia.

International Classification:

A61B 18/18

US Classification:

606 41, 607101

Abstract:

Devices, systems and methods are disclosed for the ablation of tissue. A steerable ablation catheter can include one or more ablation elements at its distal end and one or more ablation elements fixedly attached to its shaft. The distal end of the ablation catheter can be deflected to assume a number of different deflection geometries in at least one direction along the shaft. One feature of the ablation catheter is that its shaft can comprise materials of differing durometers or stiffnesses attached together at a joint. Methods associated with use of the ablation catheter are also covered.
