Abstract:
1. A prosthesis anchor assembly comprising: an anchor having: a single-layer mating prosthesis having an expanded configuration with a wall including a ridge defining a similar configuration as the inwardly extending radial protrusion, the wall having a larger diameter portion at least one side of the ridge and a smaller diameter at the ridge, the ridge of the prosthesis being engaged by the inwardly extending radial protrusion of the docking section of the anchor such that longitudinal movement of the prosthesis is prevented; and a permanent fixation configured to penetrate the single landing section and the body lumen to fix the anchor to the body lumen such that the separate single landing section is the only section of the anchor configured to touch and be fixed to the body lumen because the first portion of the wall of the docking section extends radially inwardly and has a second diameter, smaller than the first diameter, thereby defining an inwardly extending radial protrusion.
