Method of installing vascular access device
First Claim
1. A method of implanting a vascular access device in the body of a patient comprising the steps of:
- forming a body access opening;
providing a body access guide wire;
inserting the body access guide wire into the body access opening and directing the body access guide wire to a preselected site in the patient;
forming a tunnel between said body access opening and a tunnel opening remote from said body access opening;
providing a tunnel guide wire;
inserting the tunnel guide wire into one opening of the body access opening and the tunnel opening and directing the tunnel guide wire out of the body through the other opening of the body access opening and the tunnel opening;
providing a tunnel sheath with a forward distal end and an enlarged diameter region toward a trailing end of the tunnel sheath;
inserting the tunnel sheath into the tunnel opening;
guiding the tunnel sheath along the tunnel guide wire until the distal end of the tunnel sheath exits from the body access opening and the enlarged diameter region is inserted through the tunnel opening;
removing the tunnel guide wire from the patient;
providing an elongated vascular access device having a delivery tube operatively coupled to a first end of the elongated vascular access device;
inserting the delivery tube of the vascular access device into the open enlarged diameter region of the tunnel sheath;
pushing the elongated vascular access device into the tunnel sheath so that the delivery tube exits from the body access opening and the elongated vascular access device is received through the tunnel opening;
removing the tunnel sheath;
providing a body access sheath;
guiding the body access sheath down the body access guide wire to the preselected site in the patient;
removing the body access guide wire;
directing the delivery tube into the body access sheath to guide the delivery tube to the preselected site in the patient; and
removing the body access sheath.

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.

13. A method of implanting a vascular access device in the body of a patient comprising the steps of:
-
inserting an introducer needle into a first location of the body, the needle having a lumen extending therethrough; inserting a first guide wire into the needle through said lumen and extending the first guide wire to the desired location in the body; removing said needle; inserting an introducer needle into the body at a second location to extend through and protrude from the body at the first location; inserting a second guide wire into the needle through the lumen of the second needle and extending the second guide wire to exit from the body at the first location; removing the introducer needle; guiding a tunnel sheath along the second guide wire using a dilator, the tunnel sheath having a distal end and an open proximate end; pushing the tunnel sheath with a dilator so that the distal end of the tunnel sheath exits from the body at the first location; removing the dilator and the second guide wire from the body; inserting a vascular access device into the open proximate end of the tunnel sheath, the vascular access device having a delivery tube extending therefrom; directing the delivery tube to exit through the first location; removing the tunnel sheath; guiding a second sheath along the first guide wire with a dilator, the second sheath having an open proximate end and a distal end; removing the dilator and the first guide wire from said body; directing the delivery tube down the second sheath through the open proximate end of the second sheath; and removing the second sheath. - View Dependent Claims (14, 15)

16. A method of implanting a vascular access device in the body of a patient comprising the steps of:
-
providing a first guide wire; inserting the first guide wire into the body of the patient, thereby forming a first opening; directing the first guide wire to a preselected site in the patient; providing a second guide wire; inserting the second guide wire into the body of the patient; projecting a distal end of the second guide wire out of the body through the first opening and a proximate end of the second guide wire through a second opening remote from said first opening; providing a first sheath and a dilator; guiding the first sheath down the first guide wire with the dilator; removing the first guide wire and the dilator; providing a second sheath with a forward distal end and an enlarged proximate end; inserting the distal end of the second sheath with the dilator into the second opening; guiding the second sheath with the dilator along the second guide wire until the distal end of the second sheath exits from the first opening and the enlarged proximate end is inserted into the second opening; removing the dilator and the second guide wire from the patient; providing a vascular access device having a first end and a delivery tube operatively coupled to the first end of the vascular access device; inserting the delivery tube of the vascular access device into the open enlarged diameter region of the second sheath; pushing the vascular access device into the second sheath so that the delivery tube exits from the first opening and the vascular access device is received through the second opening; directing the delivery tube into the first sheath to guide the delivery tube to the preselected site in the patient; and removing the first sheath and the second sheath. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
