Publication number: 20220330970Abstract: An intravascular catheter device includes an expandable portion secured to a flexible catheter tube and configured for controllable movement between a first position where at least a portion of each of a plurality of struts is moved outward so as to extend beyond an outer surface of a sheath and a second position where the struts are compressed. A limiter for restricting expansion of the expandable portion is interposed between the expandable portion and a tip member located distal to the expandable portion. An incising element associated with one of the struts is configured to incise tissue located within a blood vessel when the expandable portion is placed in the first position and retracted axially along the blood vessel.Type: ApplicationFiled: July 1, 2022Publication date: October 20, 2022Inventors: John P. Pigott, Jenny Zeroni, Adam Tschida

Publication number: 20210346051Abstract: An atherectomy catheter having an inner drive shaft which rotates a distal rotary tissue borer with a helical cutting surface which enables the catheter to cut through and cross a CTO. Additionally, the atherectomy catheter has a distal cutting element rotated by an outer drive shaft configured to cut material from the wall of a vessel at a treatment site as the catheter is pushed distally through the treatment site. The atherectomy catheter includes a collection chamber positioned proximally of the cutting element and rotary tissue borer. The atherectomy catheter may include means to direct material cut from the treatment site into the collection chamber, means to break down larger portions of material that may block or clog the collection chamber and means of transporting the material collected from the treatment site to a proximal opening in the atherectomy catheter.Type: ApplicationFiled: March 22, 2021Publication date: November 11, 2021Inventors: Jenny Zeroni, Robert Wayne Van Pelt, JR., Cory David Sills, Scott Petersen, Nick Jan Van Der Lugt
