Abstract: A catheter having a multilumenal tube surrounded by a slotted hypotube is provided. The catheter has a tube holder that houses the multilumenal tubing and slidably engages the hypotube, and has internal passages configured to receive one of more tubes from the multilumenal tube. The multilumenal tubing separates into one or more tubings, each comprising a lumen, such that the tubings exit the tube holder at different locations. The slotted hypotube slidably engages a key in the tube holder that prevents the multilumenal tubing from rotating relative to the tube holder and the one of more tubings that separate from the multilumenal tubing. Advantages provided by the slotted hypotube/tube holder assembly are described.

Abstract: The present disclosure describes an angioplasty balloon catheter having a retractable sheath and a flexible tip attached to the distal end of the sheath. The flexible tip is made of an elastomeric plastic that is capable of returning to its original shape after being expanded multiple times. The tip allows for the sheath to be retractable and the balloon inflated multiple times to treat or expand different locations within the vessel. Because the tip returns to its original shape each time, the tip is less likely to damage the vessel wall when the sheath is repositioned in the vessel, and also is easier to retract through a guide-catheter.
