Abstract
The present invention provides a lumen support prosthesis composed of interlocking radial modules which is fabricated fully assembled from a signal piece shape, without welding or bonding. The prosthesis comprises at least one locking mechanism, allowing for one-way sliding of the radial modules and expansion of the prosthesis from a collapsed state, but inhibits radial recoil from the expanded diameter. The prosthesis may be fabricated from biologically degradable materials which have certain medical advantages.
Claims6
A method for manufacturing a prosthesis comprising separate interlocking components, the method comprising:
- fabricating from a material a contiguous one-piece blank comprising a first plane and a second plane and an intersection therebetween;
- machining, by cutting or etching, in the first plane a pattern comprising a loop having a slide and lock structure therein, said pattern abutting the intersection at a location;
- machining, by cutting or etching, a slot through the second plane at the location, said slot being configured to engage the slide and lock structure, wherein the first and second planes are joined by residual material along the intersection;
- and
- removing the residual material to separate the first and second planes, wherein the planes remain slideably coupled to one another.
