Abstract
A device for tissue ablation and a method of using the device.
Claims22
A method for ablation of cardiac tissue, comprising the steps of:
- contacting a device for cardiac ablation with said cardiac tissue;
- said device comprising an ablation element and a surface gripping element for folding said tissue and for contacting said tissue with said ablation element;
- gripping said cardiac tissue with said gripping element;
- folding said cardiac tissue gripped with said gripping element;
- applying ablation energy to said ablation element;
- and,
- ablating said cardiac tissue.
4 more elements
A device for ablation of cardiac tissue, comprising:
- a handle;
- at least one ablation element;
- and
- at least one gripper arm, said gripper arm comprising tissue gripping elements for folding said tissue and for contacting said tissue fold with said ablation elements.
1 more element
A system for ablation of cardiac tissue, comprising:
- at least two gripper arms, one of said gripper arms comprising a ridge;
- an ablation tube comprising a tissue contacting surface and a groove for interfacing with said ridge on said gripper arm;
- and
- at least one ablation element disposed on the tissue contacting surface of said ablation tube, wherein said at least two gripper arms grip said tissue to cause a tissue fold, and said ablation element on said ablation tube contacts said tissue fold to ablate said tissue.
