    Abstract: The present invention is a stent delivery system including a catheter, wherein the catheter includes an inflatable region. An expandable stent is disposed about at least a portion of the inflatable region. A first end of the at least one stent retaining sleeve covers an end of the stent prior to the stent being expanded for delivery. A second end of the at least one sleeve is engaged to at least a portion of the catheter adjacent to the inflatable region. The at least one stent retaining sleeve is constructed and arranged to longitudinally foreshorten from a first predetermined length to a second predetermined length when the stent is expanded for delivery. The second predetermined length being more than 5 percent shorter than the first predetermined length. When the stent is expanded for delivery, the at least one stent retaining sleeve is retracted off of the stent thereby releasing the stent from the catheter.

    Abstract: A balloon catheter comprises an inner tube, a medical balloon and an inflation lumen. The medical balloon is disposed about the inner tube and in fluid communication with the inflation lumen. A collapsible portion of the inner tube is constructed to collapse inward upon delivery of an inflation fluid to the medical balloon to secure the inner tube to the guidewire.

    Abstract: A catheter is disclosed providing a balloon catheter having a distal tip that is flexible while additionally incorporating high column strength. The present invention additionally provides a distal tip region that accommodates for various sized guidewires. In preferred embodiments, the distal tip region is initially configured for accommodating the passage of 0.12-inch guidewires only. Through specific manufacturing processes, however, the distal tip is modified so that it also may be expanded to accommodate the passage of 0.14-inch guidewires. In additional preferred embodiments, an elastomeric sleeve is disposed over the modified distal tip to allow the tip to return to the initial 0.12-inch accommodating profile when the larger 0.14-inch guidewire is withdrawn from the catheter.

    Abstract: Devices and methods for managing a portion of an intravascular catheter which is extending from the body of a patient under operating room conditions (e.g., while a physician is wearing surgical gloves). A catheter in accordance with one embodiment of the present invention includes a catheter shaft having a proximal end and a distal end, and a keeper fixed to the catheter proximate a proximal end thereof The keeper includes one or more inside surfaces defining a channel which is adapted to entrap a straight portion of the catheter shaft. The keeper also includes a passageway which is adapted to allow a curved portion of the catheter to pass into the channel of the keeper.
