  • Patent number: 6991646
    Abstract: Method and apparatus for delivering a stent, including, but not limited to, a self expanding stent, into a body lumen. The apparatus comprises an outer tube having a proximal end and a distal end and sized to hold a stent therein in a radially constricted condition, an inner tube within the outer tube and having a proximal end and a distal end, and a holding element comprising one or more inflatable balloons carried on the inner tube at the location of the loaded stent. The balloon can be inflated prior to the procedure so that the balloon presses against the inner surface of the outer tube trapping the stent in its longitudinal position between the inner and outer tubes. Accordingly, the outer tube can be slid proximally to release the stent or distally to retract the stent back into the delivery device without the stent inadvertently sliding.

  • Patent number: 6902575
    Abstract: A method and apparatus for inserting a self expanding stent into a delivery device and delivering the stent into a body lumen. The apparatus comprises an outer tube; an inner tube; a capturing element slidably mounted on the inner tube and including a foldable sleeve, a blocking element fixed to the inner tube adapted to block a stent from being inserted into the sleeve proximally of the blocking element and to block the capturing element from becoming situated distally of a predetermined point relative to said inner tube, the capturing element carried on the inner tube so that the distal end of the sleeve can extend beyond the distal end of the outer tube in an unfolded condition and be drawn into the outer tube by the blocking element. A stent having an end inserted into the sleeve is drawn into the outer tube, thereby becoming captured within the outer tube.
