Hemodialysis catheter sleeve

A hemodialysis vascular access device comprising:

• a compressible proximal end sized and shaped to sealably couple to a hemodialysis catheter;
• a movable structure coupled to the compressible proximal end and sized and shaped to receive a portion of the hemodialysis catheter;
• a fixation structure coupled to the compressible proximal end, the fixation structure sized and shaped for fixation on a patient, the fixation structure sized and shaped to receive a portion of the hemodialysis catheter;
• a distal end comprising an elongated sleeve coupled to the fixation structure, the elongated sleeve sized and shaped for insertion into a patient's vasculature, the elongated sleeve having an internal lumen sized and shaped to receive a portion of the hemodialysis catheter;
• and
• a valve at a distal end of the internal lumen;
• wherein the vascular access device is configured such that, when the hemodialysis catheter is inserted into the vascular access device and coupled to the compressible proximal end, distal movement of the movable structure relative to the fixation structure forces a distal end of the hemodialysis catheter through the valve, out of the internal lumen, and into a patient's blood.
