Abstract

A hemodialysis vascular access device includes a proximal end sized and shaped to sealably couple to a hemodialysis catheter, a movable structure coupled to the proximal end, a fixation structure coupled to the movable region and sized and shaped for fixation on a patient, an elongated sleeve coupled to the fixation structure and sized and shaped for insertion into a patient's vasculature, and a valve at a distal end of the internal lumen. When a hemodialysis catheter is inserted into the device and coupled to the proximal end, distal movement of the proximal end relative to the fixation structure biases a distal end of the hemodialysis catheter from a position inside the elongated sleeve through a valve out of the device and into the patient's blood.
