Jeffrey M Isner, Richard Clarke: Catheter. AngeLase, Hugh D Jaeger, April 14, 1992: US05104393 (189 worldwide citation)

A technique for the treatment of ventricular tachycardia. The ventricles are endocardially mapped by way of an electrophysiological workup. This mapping locates the tachycardial foci and other abnormalities in conduction. A special catheter containing an optical fiber is percutaneously inserted into ...

Jeffrey M Isner, Richard Clarke: Catheter. AngeLase, Hugh D Jaeger, April 21, 1992: US05106386 (144 worldwide citation)

A technique for percutaneous treatment of idiopathic hypertrophic subaortic stenosis (IHSS) and hypertrophic cardiomyopathy (HCM). IHSS and HCM are diseases of the heart in which the septum of the left ventricle thickens resulting in reduced ventricular performance. Current treatments involve drug t ...
