Latest Patents

Marzelle holds a patent for a vascular graft device placement method. This patent outlines a procedure for positioning a graft device in the ascending aorta of a patient. The method involves providing access to a peripheral venous site and advancing a first catheter through this site to the right atrium. Subsequently, access is provided to the left atrium across the intra-atrial septum, allowing the first catheter to be advanced into the left atrium. A second catheter is then advanced from the first catheter through the left ventricle and the aorta to a peripheral arterial site. The graft device, which is disposed on or within the second catheter, is advanced until it reaches the ascending aorta, where it is positioned at the treatment site. Finally, both catheters are removed from the patient.
