Abstract

A vascular access device is provided which can be used for chronic venous or organ access. When implanted, the device facilitates repeated intermittent infusions of medical treatment while reducing the risk of infection at the implant site. The vascular access device comprises an elongated body and a delivery tube coupled to the elongated body for delivering the medical treatment to a preselected site in a patient's body, which permits subcutaneous implanting of the device with a minimally invasive procedure. A sheath and a dilator are adapted to form an access tunnel in the patient's body commensurate in configuration with the elongated body of the device. A guide wire is provided to guide the sheath and dilator from a first opening to a second opening in the patient's body. The introduction of the sheath eases the placement of the device and reduces access site trauma to the vein, organ, or any other location in the body to which the medicine or therapy is to be applied. Once implanted, the delivery tube of the device cooperates with another sheath, which is inserted and guided along another guide wire that extends to the preselected site in the patient's body. Furthermore, a retrieval tool is provided which cooperates with the elongated body of the device for removal of the device from the body.
