Abstract
A delivery system with sequential release mechanism and method of delivering and deploying an implantable stented device into a body lumen including a tabular body, a plurality of activation members extending from the distal end of the tubular body, and a plurality of disks. Each disk includes a proximal and distal surface, at least one stent engagement element attached to the distal surface of the disk and at least one aperture. At least one activation member attaches to the proximal surface of a first disk and at least one activation member passes through an aperture of the first disk and attaches to the proximal surface of a second disk. At least one stent engagement element attached to the distal surface of the first disk passes through an aperture of the second disk. Axially movement of the activation members causes sequential release of the stent engagement elements from a stented device.
