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.
