CATHETER ASSEMBLY FOR TREATMENT OF HYPERTROPHIC TISSUE

摘要

The present invention teaches a new apparatus and process of selective ablation of the hypertrophic tissue to treat hypertrophic cardiomyopathy. The apparatus and process involve percutaneously delivering radiofrequency energy through a manipulable catheter to irradiate the thickened septum to reduce tissue volume of the septum and enhance myocardial function. The invention also teaches use of a thermosensor feedback control to prevent coagulation at the RF producing electrodes and navigating the catheter with an ultrasound transducer operably attached to the catheter assembly.

主权项

1. A catheter assembly for treating hypertrophic tissue, comprising:
a catheter with a proximal end and a distal end, with a top length and a bottom length, with at least one lumen, wherein the distal end of said catheter is soft and flexible, wherein the distal end of said catheter has at least one repositioning tension member attached inside said catheter; at least one RF producing electrode at the distal end on the top length of said catheter; and a wire running inside one lumen providing power to said electrode.
