Abstract: A device is configured to identify a breathing sound contained in acoustic signals from outside. The device has a processor, a display coupled to the processor and a memory coupled to the processor and storing instructions. The instructions, when executed by the processor, cause the processor to perform a first identifying process upon a start command and to perform a second identifying process upon a stop command subsequent to the start command. In the first identifying process, a first identified result is displayed on the display, the first identified result indicating whether the breathing sound obtained during a first predetermined period is normal or abnormal. In the second identifying process, a second identified result is displayed on the display, the second identified result indicating whether the breathing sound obtained during a second predetermined period is normal or abnormal.

Abstract: 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.
