    摘要： A carrier tube assembly for packaging a medical catheter is disclosed. The carrier tube assembly includes an elongate tube, a medical catheter, and a plug. At least a distal portion of the elongate shaft of the medical catheter is positioned in the lumen of the elongate tube such that the proximal end of the elongate tube is hermetically sealed around a portion of the hub assembly of the medical catheter. The plug is inserted into the lumen of the elongate tube at the distal end of the elongate tube, hermetically sealing the distal end of the elongate tube. Thus, a hermetically sealed environment is established within the elongate tube. The plug includes a moisture and/or oxygen absorbing agent to absorb moisture and/or oxygen in the hermetically sealed environment.

    摘要： An atherectomy burr has an operating diameter that is larger than the diameter of a catheter in which the burr is routed. The burr may include an expandable polymeric balloon having a partially abrasive exterior surface. The maximum expansion of the burr is controlled by an expansion mechanism. Various mechanisms are disclosed for controlling the maximum diameter of the burr thus preventing the burr from over expanding. In addition, the present invention includes systems that are pulled proximally to remove portions of a lesion located in a patient's vasculature. The system includes an ablation burr that has abrasive disposed on the proximal end. The burr may create a seal when expanded to block the ablated particulate so that an aspiration system can remove the particulate from the vasculature. Alternatively, the burr system may include a self expanding seal that is deployed out of the aspiration sheath.

    摘要： An atherectomy burr has an operating diameter that is larger than the diameter of a catheter in which the burr is routed. The burr may include a polymeric balloon that is coated with an abrasive and that expands when the burr is rotated. When the burr is rotated, the polymeric tube expands by centrifugal force. The maximum expansion of the burr is controlled by an expansion mechanism. Various mechanisms are disclosed for controlling the maximum diameter of the burr thus preventing the burr from over expanding. In addition, the present invention includes a system for preventing the loose ablated particulate from reembolizing in the distal vasculature. The system includes an ablation burr that has abrasive disposed on the proximal end that is pulled back toward the guide catheter to ablate the lesion. The burr creates a seal when expanded to block the ablated particulate so that the aspiration system can remove the particulate from the patient vessel or stent. Alternatively, the burr system may include a self expanding seal that is deployed out of the aspiration sheath so that a slight vacuum can remove the large loose particulate form, the patient's vessel or stent.

    摘要： Articles such as catheters or balloons that have an ester-linked poly(ester-block-amide) substrate have a lubricious hydrogel coating which suppresses particle development under accelerated aging conditions. A polymerizable coating composition is applied to the substrate without application of an intervening primer layer and cured. The coating composition comprises an uncrosslinked polyvinylpyrrolidone polymer that is free of attached photoinitiator groups and at least one polyfunctional ethylenically unsaturated monomer.
