NeuRx Medical is developing the NeuRx Sweeper™, a low-profile adjunct catheter designed to remove organized, adherent clot during thrombectomy for deep-vein thrombosis and pulmonary embolism. Founded by medical-device commercialization executive Timothy Clark, the company uses a radially expanding nitinol capture node to apply mechanical traction where aspiration alone can leave residual thrombus. The investigational device has completed bench and animal feasibility testing, while NeuRx advances it toward FDA 510(k) clearance.
