A penile prosthetic includes a proximal tip in communication with a reservoir, a cylinder bladder connected at a proximal end to the proximal tip and extending to a distal end, and peristaltic tubing disposed inside the cylinder bladder. The peristaltic tubing has a proximal end that communicates with the reservoir and a distal end that is open to the cylinder bladder. Peristaltic compression applied from the proximal end to the distal end of the peristaltic tubing pumps fluid from the reservoir into the cylinder bladder.
