Publication number: 20250099223Abstract: A vascular access device and assembly characterized by a tubular access graft having at least one angled distal flange that forms a non-circular distal opening to the tubular access graft, with the angled distal flange having a reinforcement structure that expands the flange and abuts a luminal wall surface of a blood vessel. Optionally, an axial compression ring or cuff may be provided that concentrically engages the tubular access graft and is translatable into a position that abuts an abluminal wall surface of the blood vessel. Also optionally, the device and assembly may include an annular ring with a plurality of axially projecting tines arrayed about a circumference of the annular ring, the annular ring being adapted to evert upon engagement with vascular tissue and creation of an access open by either an arteriotomy or a venotomy. The plurality of tines are configured to engage vascular tissue and then rotate to a different axial orientation to evert the periphery of the access site.Type: ApplicationFiled: September 19, 2024Publication date: March 27, 2025Applicants: Connex Biomedical, Inc., The Board of Regents of University of Colorado, a body corporateInventors: Max Bannister Mitchell, Jeremy H.
