    Abstract: A guidewire apparatus for a medical device that includes an expandable guidewire section that can be locked in an expanded state. In one use, the expandable section can be temporarily locked to a working element of a medical device to facilitate the transmission of torque from the guidewire to the medical device. Hence, this configuration may be utilized to aid in orientation of the working element with a vessel side branch by providing the user with the ability to apply a rotational force to the distal end of the stent delivery system. Another use includes docking the expandable section near an opening into a guidewire lumen at the catheter tip. This configuration is particularly useful in forming a smooth transition between the guidewire and the catheter tip to reduce the phenomenon of fish-mouthing.

    Abstract: The present invention concerns a novel bifurcated stent apparatus for use in treating lesions at or near a bifurcation point in bifurcated vessel. More particularly, a dedicated bifurcation stent apparatus is fabricated from a single tube structure for use in a bifurcated body vessel having a main lumen and a side lumen. The stent apparatus includes a first stent portion comprised of a first stent pattern that is configured for radial expansion into a generally cylindrical main body. A second stent portion is integrally formed with the first stent portion, and includes a second stent pattern configured to form a first branch leg and a second branch leg. Collectively, the first stent portion, and the branch legs form a crocodile cut shape. Each branch leg is of a cylindrical shell-shaped arc segment in a first condition, and each of the first branch leg and the second branch leg is patterned for manipulation and radial expansion, in a second condition, into a generally cylindrical first body and a generally cylindrical second body, respectively.

    Abstract: A stent delivery system is disclosed for delivering and deploying a radially expandable stent at a strategic orientation and location in a body vessel. The delivery system includes an elongated flexible tubular shaft sized suitably for insertion into the body vessel. A stent deployment assembly includes a distal transition portion supporting a dilator device adapted for radial expansion about a longitudinal axis of the deployment assembly from a non-expanded condition to a radially expanded condition. The dilator device is configured to support the stent thereon in the non-expanded condition and in predetermined orientation relative the deployment assembly. A rotational clutch assembly rotatably mounts the transition portion to a distal portion of the tubular shaft such that the deployment assembly is substantially torsionally isolated from the tubular shaft, about a longitudinal axis of the clutch assembly. This enables the stent deployment assembly to rotate substantially independently of the tubular shaft for strategic orientation of the dilator device during advancement through the body vessel.
