US Patent:

7860578, Dec 28, 2010

Filed:

Aug 8, 2007

Appl. No.:

11/891065

Inventors:

Eugene J. Jung - Nesconset NY, US
Dong Ik Shin - Poway CA, US
Eric Scott Vaughan - San Francisco CA, US

Assignee:

Boston Scientific Scimed, Inc. - Maple Grove MN

International Classification:

A61N 1/00

US Classification:

607122

Abstract:

A cardiac ablation device, including a catheter and an expandable ablation element incorporating one or more balloons at the distal end of the catheter, has a continuous passageway extending through it from the proximal end of the catheter to the distal side of the expandable ablation element. A probe carrying electrodes is introduced through this passageway and deploys, under the influence of its own resilience, to a structure incorporating a loop which is automatically aligned with the axis of the expandable ablation device, so that minimal manipulation is required to place the probe. The probe may have an atraumatic tip with a ball formed at the leading edge. The atraumatic tip prevents any tissue damage such as perforation of heart wall.
