Attachment plates and implants for penile construction

An implantable device for penile construction, the implantable device comprising:

• a penile prosthesis having a distal end portion and a proximal end portion, the proximal end portion defining an attachment interface;
• an anchor plate configured to be coupled to a pelvic bone of a patient, the anchor plate having an attachment interface configured to be coupled to the attachment interface of the penile prosthesis, the anchor plate having a first portion, a second portion, and a central portion disposed between the first portion and the second portion such that a central axis of the anchor plate extends through the central portion at a location equidistant from the first portion and the second portion, the first portion being formed of a first material, the central portion being formed of a second material, the second material being more flexible than the first material, the anchor plate having a side edge extending from a first corner portion to a second corner portion, the side edge being curved from the first corner portion to the second corner portion such that a midportion of the side edge between the first corner portion and the second corner portion is disposed closer to the central axis of the anchor plate than the first corner portion is disposed to the central axis of the anchor plate and the midportion of the side edge between the first corner portion and the second corner portion is disposed closer to the central axis of the anchor plate than the second corner portion is disposed to the central axis of the anchor plate.
