METHOD AND SYSTEM OF DEVICES FOR PERMANENT ACCESS TO THE CIRCULATORY SYSTEM FOR CHRONIC HEMODIALYSIS

摘要

The system and method provide ways to achieve vascular access, e.g., for chronic hemodialysis. The system includes a port which may be bonded to a vascular graft which is installed between an artery and vein. A movable seal occludes a lumen of the port which when deployed allows access to the blood flow, allowing hemodialysis. A stent may be employed with an extension that is part of the graft. A connector may lock on to the port to deploy the seal to make a connection between the patient and a dialyzer. A cap may cover the port and seal for sterility. Methods of using the system are also disclosed.
