Technical Field

The present disclosure relates generally to body implants, and more particularly to inflatable penile prostheses with reinforcing members.

Background

One treatment for male erectile dysfunction is the implantation of a penile prosthesis that mechanically erects the penis. Some existing penile prostheses include inflatable cylinders or members that may be susceptible to undesirable inflation characteristics. For example, some known inflatable members are formed of a fabric or knitted material that may have defects. Such defects may lead to irregular diameter and length expansion characteristics. Additionally, some known inflatable members may not provide sufficient stiffness and rigidity when inflated.

Accordingly, it would be advantageous to provide a body implant, such as a penile prosthesis, that includes an improved inflatable member.
