Publication number: 20220387069Abstract: A catheter can restore the patency of a body lumen, for example, by removing tissue from a body lumen (e.g., a blood vessel). The catheter can be a rotational catheter having a rotatable drive shaft and a tissue-removing element secured to the drive shaft to be driven in rotation by the drive shaft. The catheter can have an abrasive burr configured to abrade tissue in a body lumen. The catheter can have an expandable tissue-removing element. The catheter can include a balloon and an inflation conduit. The catheter can also be configured to move over a guidewire through a body lumen. In one embodiment, the catheter comprises an over-the-wire, balloon-expandable, rotational, and abrasive tissue-removing catheter.Type: ApplicationFiled: May 19, 2022Publication date: December 8, 2022Inventors: Mark Schneider, Ethan Andrew Guggenheimer, Nickolas Miller, Sengkham Sirivong, Bradley Steele, Babak Tabesh, Akshay Hulasare, Julie Bu

Patent number: 10905459Abstract: A tissue-removing catheter includes a tissue-removing element operably connected to a drive shaft for rotation of the tissue-removing element about an axis of rotation in a cutting direction. The tissue-removing element is an integrally formed, one-piece body and has an annular tissue-removing head at the distal end of a tissue-removing element body. In some embodiments, primary tissue-removing components include an integrally formed cutting tooth and inner shearing member and are spaced angularly around the tissue-removing blade. Secondary tissue-removing components include cutting teeth and are interposed between the primary tissue-removing components around the tissue-removing blade. The tissue-removing element is made by removing material from a blank to form the primary and secondary tissue-removing components.Type: GrantFiled: June 7, 2016Date of Patent: February 2, 2021Inventors: Ethan Andrew Guggenheimer, Victoria Schuman, Lucas Schneider, Benjamin Robert Fruland

Patent number: 10905458Abstract: A tissue-removing catheter includes a tissue-removing element operatively connected to a drive shaft for rotation of the tissue-removing element about an axis of rotation in a cutting direction. A tissue-removing head of the tissue-removing element defines an annular cutting blade. In some embodiments, angularly spaced cutting teeth form the cutting blade. Inner shearing members extend radially inward from the cutting blade. As the tissue-removing element rotates in the cutting direction and advances axially through a body lumen, the annular cutting edge separates the tissue from the body lumen wall. Leading surfaces of the inner shearing members shear the separated tissue radially inwardly. In some embodiments, the tissue-removing element is an integrally formed, one-piece body made by removing material from a blank to form the cutting blade and inner shearing members.Type: GrantFiled: June 7, 2016Date of Patent: February 2, 2021Inventors: Ethan Andrew Guggenheimer, Victoria Schuman, Virgil Koski, Benjamin Robert Fruland, Lucas Schneider

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

Patent number: 9326789Abstract: Catheters and methods for removing material from (or “debulking”) a body lumen while imaging the region comprised of the material are provided. The catheters can be used in body lumens, including but not limited to intravascular lumens such as coronary or peripheral arteries. The catheters include housings or other structures to mount or protect an imaging transducer. Generally, debulking catheters include a proximal portion, a distal portion having an opening, a cutting element which may be exposed through the opening to contact material in a body lumen and an imaging transducer with associated circuitry and display. The catheter debulks a body lumen when it is moved while the cutting element is in contact with the material in the lumen and the region comprised of the material is imaged before, after, or during catheter movement.Type: GrantFiled: June 13, 2014Date of Patent: May 3, 2016Assignee: Covidien LpInventors: Benjamin Robert Fruland, Zachary Thomas Garvey, Ethan Andrew Guggenheimer, Thomas John McPeak, John Arthur Pedersen, Scott Robert Petersen, Lindsay Ann Crescenzo
