Patent number: 11918753Abstract: A flexible, elongated catheter tube having distal and proximal ends and a laser cut section there between. The laser cut section makes up a majority of the catheter length and is cut in a continuous helical pattern forming interlocking teeth which can be sinusoidal, triangular, square or like shapes, preferably sinusoidal. The interior of the tube has a polymeric layer which forms the internal lumen of the catheter. The exterior of the tube has a polymer coating. A short portion of the distal end is uncut and is followed by a narrower terminal section which can be tapered for better blockage penetration. The interlocking teeth disengage and reengage in a fish-scale manner without undergoing plastic deformation of the metal tube and without substantial polymer separation from the tube exterior.Type: GrantFiled: October 15, 2019Date of Patent: March 5, 2024Assignee: TRACTUS VASCULAR, LLCInventors: Craig Moquin, Andrew Filachek, Paige Reinhardt, Matthew Koehler, Darren De Medici, Janet Burpee

Publication number: 20230405299Abstract: Described herein are pumps that linearly reciprocate to assist with circulating blood within the body of a patient. Red blood cell damage may be avoided or minimized by such linear pump movement. The linearly reciprocating movement may also generate a pulsatile pumping cycle that mimics the natural pumping cycle of the heart. The pumps may be configured to reside at various body locations. For example, the pumps may be situated within the right ventricle, the left ventricle, the ascending aorta, the descending aorta, the thoracic aorta, or the abdominal aorta. In some instances, the pump may be deployed within the venous circulation. In other instances, the pump may reside outside the patient.Type: ApplicationFiled: August 31, 2023Publication date: December 21, 2023Inventors: Steve C. SMITH, Brian A. BABSON, David J. CLINE, Mark GLINDMEYER, Andrew FILACHEK

Patent number: 11083583Abstract: Implantable valve for treating venous insufficiency having a self-expanding frame encased in polymer having a distal section for blood in-flow, a bulbous center section and a proximal section for blood out-flow. Polymeric leaflets have proximal ends forming an S-shaped valve outlet, or a valve outlet which spirals toward the proximal section. The valve opens and closes in response to venous blood flow and has distal portions which are integral with the inner polymer surface of the distal end of said bulbous section. The leaflets define a predominantly biomimetic sinus region with the bulbous section. Opening of the valve induces flushing of blood from the sinus region for smooth non-traumatic blood flow through said valve.Type: GrantFiled: December 3, 2018Date of Patent: August 10, 2021Assignee: VENARUM MEDICAL, LLCInventors: Taylor Kirk, Andrew Filachek, Janet Burpee

Patent number: 10525231Abstract: A flexible, elongated catheter tube having distal and proximal ends and a laser cut section there between. The laser cut section makes up a majority of the catheter length and is cut in a continuous helical pattern forming interlocking teeth which can be sinusoidal, triangular, square or likes shapes, preferably sinusoidal. The interior of the catheter tube has a polymeric bi-layer of a nylon or like polymer at the interface of the tube interior and a Teflon or like polymer forms the interior lumen of the catheter. The exterior of the tube has a thin polymer coating of nylon or the like. A short portion of the distal end is uncut and is followed by a narrower terminal section which can be tapered for better blockage penetration.

Publication number: 20120310321Abstract: The reconstrainable stent delivery system of the present invention comprises a proximal end and distal end which include inner and outer members. A pusher is positioned at the proximal end of the inner member. A slider is located coaxially with the inner member and is positioned within the inner diameter of the stent. The slider can rotate about and move longitudinally along one of an inner shaft or tube, such as the guide wire tube, such that the proximal end of the stent can move distally as the stent deploys. A pusher can be used on the guide wire tube such that the guide wire tube, pusher, and stent move proximally relative to the outer sheath and re-constrain the stent in the outer sheath. Furthermore, the pusher and guide wire tube could move distally as the outer sheath retracts proximally for stent deployment to accommodate foreshortening.Type: ApplicationFiled: June 12, 2012Publication date: December 6, 2012Inventors: Bradley Beach, Janet Burpee, Andrew Filachek, Rajesh Kalavalapally, Neel Shah, Dana Jaeger

Publication number: 20080125849Abstract: A delivery catheter used for the delivery and deployment of self expanding stents. A distal end portion is made rotatable relative to a proximal end portion allowing unwinding of a self expanding stent around the longitudinal axis of the catheter. The rotation of the distal end portion allows for untwisting or partial untwisting of a self-expanding stent which has a torsional pre-load in a compressed state in the catheter.Type: ApplicationFiled: November 13, 2007Publication date: May 29, 2008Inventors: Janet Burpee, Bradley Beach, Rajesh Kalavalapally, Andrew Filachek
