Abstract From the Canadian patent

A prosthesis to be implanted in the penis for simulating an erection has at least one cylinder to be implanted in the corpora cavernosa. A flat coil spring is contained within the cylinder. When uncompressed the spring allows the cylinder and the penis to remain flaccid. When compressed, the spring forms a rigid column that erects the cylinder and the penis and resists bending under pressure. The spring is preferably compressed by inflating an expandable chamber adjacent to the spring within the cylinder.
