Publication number: 20230301671Abstract: Described herein is a neuroaspiration catheter for removing a blood clot in a blood vessel. The neuroaspiration catheter includes a first tube, a second tube and a wire for guiding the navigation of the catheter. The wire can be navigated to the site of the blood clot, aid the navigation of the catheter, and left in the blood vessel during and after the aspiration. If the aspiration fails, the catheter can be quickly navigated back to the site of the blood clot using the wire as a guide. Also described herein is a method of removing a blood clot using the neuroaspiration catheter.Type: ApplicationFiled: March 22, 2023Publication date: September 28, 2023Applicant: Rutgers, the State University of New JerseyInventor: Amit Singla
