Abstract: The invention is directed to a medical device, particularly a penile prosthesis, that includes an implantable element and a reservoir. The implantable element is configured to be implanted within the pelvic region of a patient and is designed to be capable of inflation and deflation via fluid transfer to and from the element. The reservoir is coupled to the implantable element. The fluid is drawn from the reservoir for inflation of the implantable element and returned to the reservoir for the deflation. The reservoir is approximately one inch or less in depth. The minimal depth enables the fluid reservoir to be placed in front of the puborectalis muscle and behind the abdominal fascia without being seen on an external view of the patient.

Abstract: A fluid reservoir for a penile implant device that includes a body portion having a sleeve from which a tube may extend. The body portion includes support structure positioned at an interior surface of the body portion near an orifice of the reservoir, which orifice leads to a fluid passage of the tube. The support structure may comprise a plurality of protrusions that are arranged around the orifice and that extend from a base portion of the body portion. The invention also relates to a method of manufacturing a fluid reservoir for a penile implant device, which includes positioning a tube in a mold and injection molding a reservoir body onto the tube. More particularly, the method may include providing a mold, positioning a tube in the mold, injecting material into the mold, curing the material, and opening the mold to remove the reservoir body and tube assembly.
