| abstract |
The present invention provides a lumen support prosthesis (10) composed of interlocking radial modules (2A, 2B, 2C, 2D) which is fabricated fully assembled from a signal piece shape, without welding or bonding. The prosthesis comprises at least one locking mechanism (6, 7, 22), 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. |
