Ablation catheter having temperature-controlled anchor and related methods

摘要

One aspect of the present disclosure includes a catheter. The catheter includes a catheter body having a temperature-controlled anchor element thereon that is configured to attach the catheter body to tissue by forming a congealed adherence layer between the anchor element and the tissue. The catheter also includes an ablation element connected to the catheter body. The ablation element is axially spaced apart from the anchor element. The ablation element is configured to ablate tissue when the anchor element is attached to the tissue.

主权项

1. A catheter comprising:
a catheter body having a temperature-controlled anchor element thereon that is configured to attach said catheter body to tissue by forming a congealed adherence layer between said anchor element and the tissue; and a radio frequency (RF) ablation element connected to said catheter body and being axially spaced apart from said anchor element, said ablation element configured to ablate tissue when said anchor element is attached to the tissue; wherein said anchor element and said RF ablation element are separated from each other by an insulating portion that surrounds said catheter body and resists heat transfer from said RF ablation element to said anchor element during operation of said catheter.
