Abstract
Methods, devices, and kits for implanting a vascular graft to perform hemodialysis treatments on patients with renal failure are disclosed. The kits can include access devices comprised of an access catheter having a guidewire lumen and stylet lumen, a guide tube having a curved distal end, a stylet, an actuator handle and a vascular graft. The methods describe techniques for using the described kits and devices for performing vascular procedures, such as percutaneous implantation of the vascular graft.
Claims18
A method of percutaneously implanting an arterio-venous graft, comprising:
- advancing a first guidewire into a lumen of a first artery from a second artery;
- advancing a second guidewire into a lumen of a first vein from a second vein;
- advancing a first access catheter over the first guidewire into the lumen of the first artery;
- advancing a second access catheter over the second guidewire into the lumen of the first vein;
- operating a first guide tube actuator to advance a first guide tube from the first access catheter toward a portion of a wall of the first artery;
- operating a second guide tube actuator to advance a second guide tube from the second access catheter toward a portion of a wall of the first vein;
- operating a first stylet actuator to advance a first stylet along a curved path through the first guide tube and through the wall of the first artery to form an arterial exit site;
- operating a second stylet actuator to advance a second stylet along a curved path through the second guide tube and through the wall of the first vein to form a venous exit site;
- and
- forming a subcutaneous tunnel between the arterial exit site and the venous exit site, wherein the subcutaneous tunnel is located in an arm of a patient.
