Tissue ablation system with a sliding ablating device and method
First Claim
1. An ablation system having a non-permeable portion, comprising:
- a handle portion having proximal and distal ends;
a flexible elongated tubular member having at least one lumen therethrough operably attached to the distal end of the handle portion, the flexible elongated tubular member constructed from a porous material;
an energy delivery device comprising at least one ablative element, the energy delivery device operably attached to the handle portion and adapted to translate within a first of the at least one lumen of the tubular member;
an ablative energy source operably attached to the at least one ablative element; and
a filler material disposed along at least one portion of the tubular member defining an initial adaptation point, wherein the flexible elongated tubular member is non-permeable to fluids at the adaptation point.

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 elongated ablation sheath includes a non-permeable portion. 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.
