The present invention relates to a system for delivering a medical prosthesis into a body lumen. The system has a spear mounted horizontally to the top of a downwardly curving pry hook assembly, a digging tooth and optional side hooks connected to the pry hook assembly, and the pry hook assembly optionally secured to a tubular support member depending perpendicularly from a plate. For example, the nozzles may be grouped by drop volume or drop mass. Furthermore, the attachment devices of the shoe strap device are removably secured to an inside or outside of the shoe.
