Abstract
A delivery system for side-delivery of a prosthetic valve includes a compression device defining a lumen having a first perimeter at a proximal end that is larger than a second perimeter of the lumen at a distal end. A loading device is coupleable to the compression device and defines a lumen having substantially the second perimeter. A distal end of the loading device includes a first gate that is movable between an open state and a closed state to at least partially occlude the lumen of the loading device. A delivery device defines a lumen having substantially the second perimeter. A proximal end of the delivery device is coupleable to the distal end of the loading device and includes a second gate movable between an open state and a closed state to at least partially occlude the lumen of the delivery device.
