Abstract
Various ablation devices having an elongate body, an omnidirectional ablation element associated with the elongate body, and an ablation shielding structure attached to at least a portion of the omnidirectional ablation element, the ablation shielding structure comprising a low energy conductivity structure, wherein the ablation shielding structure is configured to resist energy conduction only on the first side of the omnidirectional ablation element, thereby increasing ablation potency on a second side opposite the first side.
Claims21
An ablation device comprising:
- a) an elongate body;
- b) an omnidirectional ablation element disposed at a distal end of the elongate body;
- and
- c) an ablation shielding structure attached to a first side of the omnidirectional ablation element, the ablation shielding structure comprising a low energy conductivity structure, wherein the ablation shielding structure is configured to resist energy conduction only on the first side of the omnidirectional ablation element, thereby increasing ablation potency on a second side opposite the first side.
1 more element
An ablation device comprising:
- a) an elongate body comprising a lumen defined within the elongate body, wherein the lumen is configured to have a vacuum applied thereto;
- b) an ablation element disposed at a distal end of the elongate body;
- c) a conduit disposed within the lumen and in fluidic communication with the ablation element, wherein the conduit is configured to allow ablation fluid to pass through the conduit;
- and
- d) an ablation shielding structure attached to the ablation element, wherein the ablation shielding structure is configured to block ablative conduction to or from a limited portion of a surface of the ablation element,
- wherein the vacuum insulates the conduit within the lumen, and
- wherein the ablation element is configured to direct the ablation fluid to a limited surface area of the ablation element that is rendered into a higher heat transfer area than other portions of the ablation element.
