Penile prosthesis with a scaffold nested inside a body implantable in a penis

A penile prosthesis comprising:

• a pair of penile implants including a first penile implant implantable into a first corpora cavernosum and a second penile implant implantable into a second corpora cavernosum;
• and
• a pump assembly coupled to the pair of penile implants by tubing;
• wherein each of the first penile implant and the second penile implant comprises:
• a tubular body sealed in a liquid-tight arrangement between a proximal tip implantable into a crus penis and a distal tip implantable into a glans penis,
• a scaffold nested inside of the tubular body, where the scaffold forms a sealed compartment inside of the tubular body, the sealed compartment of the scaffold defining a scaffold fluid capacity that is lower than a fluid capacity of the tubular body;
• a first liquid volume contained inside of the tubular body and surrounding at least a proximal portion of the sealed compartment of the scaffold, the first liquid volume fills the tubular body and has a first pressure providing the tubular body with a flaccid state;
• wherein the pump assembly is adapted for implantation superior to each of the first penile implant and the second penile implant in a location in front of a pubic bone;
• wherein, when the pump assembly is operated, a portion of the first liquid volume contained inside the tubular body is moved from a first location between the tubular body and the scaffold to a second location inside the scaffold;
• wherein the portion of the first liquid volume moved into the scaffold fills the scaffold capacity and increases pressure inside of the scaffold to a second pressure greater than the first pressure to expand the scaffold and inflate each of the first penile implant and the second penile implant to a rigid state.
