    摘要： The present invention satisfies the long felt need for a more compact and durable valve which may be formed in situ. The present invention provides a self-deployable valve system, a method of delivery, and a method of manufacturing for the self-deployable valve system. The present invention delivers the necessary components for forming a complete valve system in situ. The collapsed subcomponents of the system lack any functional characteristics commonly associated with a valve before being expanded. However, once expanded, the system is transformed into a competent valve for use in a wide variety of applications.

    摘要： An expandable stent that can transform between a collapsed state and an expanded state is described. The stent includes a first cross-sectional shape and a second cross-sectional shape. The first cross-sectional shape is a non-convex shape when the stent is in the collapsed state. Alternatively, the second cross-sectional shape is a convex shape when the stent is in an expanded state. The stent can be formed of super elastic Nitinol, which allows it to be shape set in the desired shape. Due to its shape setting properties and the non-convex cross-section, the stent is capable of dramatically reducing its cross-sectional radial profile which is beneficial in a variety of procedures.
