| 1993 | Invention patented by William J. Ryan on March 4th, 1993. Abstract: An atherectomy catheter for the removal of atherosclerosis, thrombosis, cholesterol deposits, fatty nodules, and other such sclerotic material from within the blood vessels of a patient. According to a preferred construction, the catheter includes no moving parts, and the undesirable material is shaved from the entire inside diameter of the vessel and captured and removed therefrom by the application of negative pressure as the catheter is withdrawn along a longitudinal segment of the vessel. The catheter of this invention is characterized by the absence of any moving parts during the cutting process and its construction to permit removal of atherosclerosis with virtually no danger of harm to the vessel itself. |
