A tool for implanting an inflatable penile prosthetic cylinder includes a barrel and a clasp. The barrel extends from a proximal end to a distal end and has a solid central portion bounded by a curved exterior perimeter of the barrel. The clasp has a proximal end that is attached to the tool and a distal end that is free to move away from and towards the barrel. The clasp has an interior surface located adjacent to the curved exterior perimeter of the barrel and an exposed exterior surface opposite of the interior surface. The interior surface of the clasp is spaced a distance away from the barrel at locations between the proximal end and the distal end of the clasp. The interior surface of the clasp touches the barrel at the distal end of the clasp.
