Several types of vascular procedures require vessel occlusion with an occlusion catheter. The procedures involve vessels of varying diameters. All Pruitt Occlusion Catheters are constructed of strong, pliable materials with balloons that inflate symmetrically and minimize vessel trauma. The Pruitt Aortic Occlusion Catheter can be used to control ruptured or acutely leaking abdominal aneurysms. The Pruitt Irrigation Occlusion Catheter can be used to provide intralumenal occlusion as well as irrigation. The Pruitt Occlusion Catheter can be used to control bleeding through a short arteriotomy without clamps or ties. Pruitt Aortic Occlusion Catheter: a transaneurysmal option for rapid control of bleeding with a malleable stylet that can be contoured for easier insertion, a central lumen for inflating the 50 cc balloon and an irrigation lumen with stopcock to prevent back-bleeding. Pruitt Irrigation Occlusion Catheter: provides intraluminal occlusion plus irrigation using a 9F balloon and dual lumen architecture for distal tip irrigation.
