IRRIGATED ABLATION CATHETER WITH DEFORMABLE HEAD

摘要

A medical probe, including a flexible insertion tube having a deformable distal end for insertion into a body cavity of a patient, the deformable distal end including a flexible and porous material configured to be brought into contact with tissue in the body cavity. The medical probe also includes a means for inflating the deformable distal end, and a channel contained within the insertion tube and configured to convey a fluid generating a mechanical force sufficient to inflate the deformable distal end and that irrigates the tissue through pores of the deformable distal end. The medical probe further includes an electrical conductor passing through the flexible insertion tube and terminating in the deformable distal end and configured to convey radio frequency (RF) energy to the tissue via the deformable distal end.
