Filed:

Sep 24, 2004

Appl. No.:

10/949014

Inventors:

Sing Fatt Chin - Fremont CA, US
Dany Berube - Fremont CA, US
Dinesh I. Mody - Pleasanton CA, US
Nancy Norris - Fremont CA, US

Assignee:

AFx, Inc. - Santa Clara CA

International Classification:

A61B 18/18
A61M 25/06

US Classification:

606 41, 606 45, 604528, 600146

Abstract:

A system and method for positioning a medical instrument at a desired biological target tissue site is provided. The system includes an elongated sheath having a deflectable distal end configured to deflect or otherwise position at least a portion of a medical instrument during a surgical procedure allowing for the placement of the deflected portion adjacent or proximate to a predetermined target tissue surface. The positioning system may be incorporated into the medical instrument. The medical instrument may be an ablation system.

US Classification:

606/015000, 606/033000, 606/041000

Abstract:

A system and method for ablating a selected portion of a contact surface of biological tissue is provided. The system includes an elongated ablation sheath having a preformed shape adapted to substantially conform a predetermined surface thereof with the contact surface of the tissue. The ablation sheath defines an ablation lumen sized to slideably receive an elongated ablative device longitudinally therethrough. The ablative device includes a flexible ablation element selectively generating an ablative field sufficiently strong to cause tissue ablation. Advancement of the ablation element slideably through the ablation lumen of the ablation sheath selectively places the ablation element along the ablation path for guide ablation on the contact surface when the predetermined surface is in strategic contact therewith. The ablation lumen and the ablative device cooperate to position the ablation element proximate to the ablation sheath predetermined surface for selective ablation of the selected portion within the ablative field.
