Patent number: 10751082Abstract: An atherectomy catheter directs particles generated by a cutting element into a collection chamber. A lumen configured to direct fluid into the tissue collection chamber.Type: GrantFiled: January 29, 2018Date of Patent: August 25, 2020Assignee: Covidien LPInventors: Zhiyong Zhang, John Robert Moberg, Hussain S.

Patent number: 10555753Abstract: The present invention provides an atherectomy catheter which has a cutting element that is able to cut both soft tissue and hard tissue, and methods of cutting material from a blood vessel lumen using a rotating cutting element. The cutting element has a sharp cutting edge that surrounds a cup-shaped surface and at least one surface of abrasive material. The cup-shaped surface directs the cut material into a tissue chamber. The cutting edge and the cup-shaped surface together are well suited to cut and remove relatively soft tissue from the blood vessel. The abrasive material surface in combination with the cutting element is well suited to abrade and remove hard material from the blood vessel.Type: GrantFiled: May 19, 2017Date of Patent: February 11, 2020Inventors: John Robert Moberg, Alex Yang, Christopher B. Brodeur, William Joseph Whealon, Kee Lee, Phyllis Yuen, Darren Doud

Patent number: 10499947Abstract: A catheter which includes a cutting element having one or more raised elements is provided. The cutting element has a cup-shaped surface at the distal end that may be smooth and continuous except for the raised elements. The raised elements have a surface that tends to direct cut particles of material towards one or more of the axis of rotation of the cutting element, the catheter axis, or a particle collection chamber. In further aspects of the invention, a cutting element oscillates in a direction roughly parallel to the axis of rotation of the cutting element.Type: GrantFiled: May 23, 2017Date of Patent: December 10, 2019Assignee: Covidien LPInventors: Zhiyong Zhang, Hussain S. Rangwala, Robert Wayne VanPelt, Jr., Ethan Andrew Guggenheimer, William Joseph Whealon, John Robert Moberg
