US Patent:

20120116200, May 10, 2012

Filed:

Dec 30, 2010

Appl. No.:

12/982629

Inventors:

Pianka Roy - Irvine CA, US
Alan de la Rama - Cerritos CA, US
Jennifer Velasco - Orange CA, US

International Classification:

A61B 5/042
B23K 31/02
B32B 37/12
B23K 1/20

US Classification:

600374, 2281735

Abstract:

An EP catheter includes a tubular body having a proximal region, a neck region, and a distal portion predisposed into a single shallow helical fixed-diameter loop configuration and including a plurality of diagnostic electrodes. In deflectable catheter forms, at least one activation wire extends through at least a portion of the proximal region of the catheter body and is adapted to deflect the up to approximately 180 degrees relative to the proximal region. The catheter can be operated manually by a clinician or via a clinician-surrogate such as a computer processor-controlled surgical system. In addition, a variety of localization, visualization, and/or orientation-specific elements can be incorporated into the devices described, depicted, and claimed herein (e.g., metallic coil members, active impedance emitting or receiving electrodes, fluoroscopically opaque materials, and the like).

Abstract:

An EP catheter includes a tubular body having a proximal region, a neck region, and a distal portion predisposed into an in-plane dual loop (at least, approximately, more or less) configuration and including a plurality of diagnostic electrodes. In deflectable catheter forms, at least one activation wire extends through at least a portion of the proximal region of the catheter body and is adapted to deflect the distal portion up to approximately 180 degrees relative to the proximal region. The catheter can be operated manually by a clinician or via a clinician-surrogate such as a computer processor-controlled surgical system. In addition, a variety of localization, visualization, and/or orientation-specific elements can be incorporated into the devices described, depicted, and claimed herein (e.g., metallic coil members, active impedance emitting or receiving electrodes, fluoroscopically opaque materials, and the like).
