Abstract: The disclosure provides plaque treatment catheter assemblies for the treatment of arterial plaques and removal of clots. One assembly includes a second catheter tube movable within a first catheter tube, and an expansion member movable within the second tube. The second catheter tube has one or more distally-disposed and outwardly-expandable plaque treatment portion(s). Another assembly includes a catheter tube and at least one channel(s) within the catheter. The channel includes an elongate member with a distally-disposed plaque scoring or clot retrieval member. Optionally, the assembly includes an expandable member that can cause movement of the scoring member.

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.
