A cap configured to be attached to a cylinder of an implantable penile prosthesis includes a body section and a tip section. The body section defines a recess that is attachable to an end of the cylinder of the implantable penile prosthesis and the tip section terminates in a tip having a curved exterior surface. The tip section defines at least one slot formed therein that extends away from the body section and has a slot axis that intersects with a longitudinal axis of the cap.
