  • Stent with tapered flexibility
    Patent number: 7935142
    Abstract: A stent comprises a plurality of serpentine circumferential bands, and a plurality of connector columns. Each connector column is located between two adjacent circumferential bands and comprises one or more connector struts. Each connector strut is connected at one end to one serpentine circumferential band and at another end to another serpentine circumferential band. The number of connectors per connector column decreases from the first free end of the stent to the second free end of the stent.

  • Nesting twisting hinge points in a bifurcated petal geometry
    Patent number: 7922758
    Abstract: A bifurcated stent that uses turning segments to reduce the strain at regions which bend at extreme angles. The turning segments can be placed on side branch petals or on connectors connecting the petals to the stent body. Combining the turning segments with connectors of different length and tethers provides for a stent with high flexibility that can accommodate various shaped body vessels. This design allows the bifurcation branch to extend easily, to a useful distance, and to be deployed along oblique angles. Best of all, this design avoids the problems of angularly strained side branch.

  • Balloon folding device
    Patent number: 7896642
    Abstract: A balloon folding device comprises a first die having an external contacting surface and a second die having a cavity. A portion of the cavity comprises a contacting surface shaped complimentary to the external contacting surface of the first die. The second die is movable with respect to the first die. A balloon catheter having a primary balloon and a secondary balloon is oriented with the secondary balloon located between the first die and the second die. The secondary balloon is folded by moving the second die toward the first die until the contacting surfaces of the dies contact, fold and deflate the secondary balloon. In some embodiments, the dies are moved until at least a portion of the external contacting surface of the first die is oriented within the cavity of the second die.

  • Device and method for delivering micronized therapeutic agents in the body
    Patent number: 7892205
    Abstract: The present invention provides a catheter and catheter assembly for delivering micronized therapeutic agents to a target site in the body and, in particular, to a target site in the heart. The micronized therapeutic agents are delivered in aerosol form or dry powder form. The present invention also provides a method of delivering micronized therapeutic agents to a target site in the body by placing the therapeutic agents in a catheter, positioning the catheter in the target site, and exposing the therapeutic agents to an energizing mechanism sufficient to create supersonic flow to carry the therapeutic agents from a stationary state in the catheter to a mobile state towards the target site.

  • Stent delivery catheter
    Patent number: 7887574
    Abstract: A self-expanding stent delivery assembly includes an elongate member with a proximal region and a distal region. The distal region has an outer tubular member. A self-expanding stent is disposed within the outer tubular member. Circumferential movement of at least a portion of the proximal region causes relative axial movement between the self-expanding stent and the outer tubular member, deploying the stent. Methods of deploying a self-expanding stent are also described.
