AXIALLY NESTED SLIDE AND LOCK EXPANDABLE DEVICE
First Claim
1. A slide-and-lock stent, comprising:
- a tubular member that is expandable from a collapsed state to an expanded state;
the tubular member comprising at least one slide-and-lock section;
the slide-and-lock section comprising separate first and second axially nested, slidably coupled structural elements, at least one of which comprises a deflectable structure configured to deflect during expansion from the collapsed state to the expanded state, thereby resisting recoil, and wherein no portion of either structural elements weaves through paired slots in the other structural element.

Abstract
The invention relates generally to expandable medical implants for maintaining support of a body lumen and, in particular, to an axially nested, diametrically expandable, slide and lock vascular device for enlarging an occluded portion of a vessel. The axially nested vascular device desirably achieves both competitive crossing profiles while maintaining other key features, such as, for example, radial strength and luminal patency. The collapsed profile can also be made very thin without compromising radial strength. Thus, the vascular device can advantageously be deployed in small and difficult to reach areas or vessels. The axial nesting substantially eliminates radial overlap between mating structural elements thereby desirably allowing for a low, uniform profile.
