Dialysis intervention access sheaths are used for vascular interventional procedures. Their purpose is to act as a conduit between a blood vessel and an external access source. With a few exceptions, obtaining vascular access in arterial-venous fistulas and grafts requires access directed towards the patient's extremity; thereby requiring the interventional operator to work from a less than desirable position. Dialysis sheaths currently on the market extend, in a straight line, slightly outside of the patient's arm, making it difficult for the interventional radiologist to work. The interventionalist must maneuver over the patient's upper arm, shoulder, neck and head. This particular interventional field is fraught with difficulties, limitations and potential complications. Radiation exposure is increased, maintenance of a sterile field is more difficult, and limitations in space add to the difficulty of the procedures. The Interventionalist also has to stand over the patient to access the sheath. Not only is this uncomfortable for the patient, but the radiologist now has his/her hands right in the area of radiation. Similar limitations are present for the Interventionalist with arterial access from an antegrade common femoral artery approach. This new technology aims to correct the difficulties associated with the current dialysis intervention and would be an extension of existing sheath technology. Besides use of this technology for access in the arm, the sheath is also ideal for antegrade arterial access from the common femoral artery, as well as biliary and renal intervention.
