Abstract
Various methods employing transvascular access devices are described, including a method of placing a central catheter in a peripheral vein in an arm of a patient; a method of providing percutaneous access to the heart of a patient; a method of clearing a clotted arteriovenous dialysis graft; a method of creating multiple access points into a single blood vessel; a method of creating an AV fistula in a patient; and a method of providing a bypass to a blockage in a popliteal artery in a patient.
Claims19
A method of placing a central catheter in a peripheral vein in an arm of a patient, the method comprising:
- inserting an access device percutaneously through an entry site in a femoral vein of the patient, the access device comprising a vascular catheter;
- advancing a distal end of the vascular catheter from the entry site to an exit site in the peripheral vein;
- advancing a puncture tool from the distal end of the vascular catheter through the peripheral vein wall and skin of the patient at the exit site;
- after the step of advancing the puncture tool, inserting the central catheter into the peripheral vein at the exit site;
- and
- inserting a micropuncture catheter into the peripheral vein at the exit site.
A method of placing a peripherally inserted central catheter in a peripheral vein in an arm of a patient, the method comprising:
- inserting an access device percutaneously through an entry site in a femoral vein of the patient, the access device comprising a vascular catheter;
- advancing a distal end of the vascular catheter from the entry site to an exit site in the peripheral vein;
- advancing a puncture tool from the distal end of the vascular catheter through the peripheral vein wall and skin of the patient at the exit site;
- advancing a micropuncture catheter over the puncture tool into the peripheral vein;
- inserting a guidewire into the peripheral vein through the micropuncture catheter;
- and
- inserting the central catheter into the peripheral vein over the guidewire.
