  • Balloon Expandable Stent Graft and Apparatus and Method for Expanding a Balloon Expandable Stent Graft
    Publication number: 20140249617
    Abstract: A stent-graft delivery system includes a balloon, a sleeve disposed over the balloon, and a stent graft mounted over the sleeve. The sleeve includes a weakened area between a first end and a second end of the sleeve such that when the balloon is expanded, the balloon expands from a center portion of the balloon towards the ends of the balloon. The weakened area of the sleeve may be a slit, a thinner wall section, grooves, notches, or other weakening features. The sleeve may be adhesively attached to an outer shaft of the catheter or to an outer surface of the balloon.

  • Method of manufacturing a crimped assembly, and related apparatuses
    Patent number: 8375552
    Abstract: A method of crimping a load-bearing member and an end fitting together such that the load-bearing member lies displaced from a center of a cross-section of the end fitting. The method includes the steps of inserting the load-bearing member into an aperture in the end fitting and advancing at least one deformation tool relative to the end fitting to deform the wall of the aperture into gripping engagement with the load-bearing member. The extent of the resulting deformation of the wall over a predetermined length thereof varies in dependence on a distance along the length from the load-bearing member.

  • Over-the-wire balloon catheter for efficient targeted cell delivery
    Patent number: 8372054
    Abstract: A method for delivering a therapeutic substance to a treatment site within a body lumen includes advancing a balloon catheter to the treatment site. A balloon of the balloon catheter is inflated and while the balloon is inflated, a primer that coats the treatment site and attracts the therapeutic substance thereto is delivered through a first fluid delivery lumen of the balloon catheter. The balloon of the balloon catheter is deflated for a predetermined period of time. The balloon of the balloon catheter is reinflated and while the balloon is reinflated, the therapeutic substance is delivered through a second fluid delivery lumen of the balloon catheter. The primer improves adherence of the therapeutic substance to the treatment site.
