  • Method and device for performing transluminal angioplasty
    Patent number: 4651738
    Abstract: A novel method and device for performing percutaneous transluminal angioplasty to treat occlusive artery disease is disclosed. The method involves simultaneous measurement and display of the fluid pressure and volume existing within the balloon catheter as the procedure is performed. Information is produced which is useful in determining the efficacy of the procedure as it is performed which obviates the need for arbitrary repeated inflations. The information is also useful in the subsequent management of the patient's disease.
