ABSTRACT:
An inflatable surgical implant having a remotely located inflation button also designed for implantation and adopted to be pierced by a hypodermic needle. A fluid conduit connector in the wall of the implant for fluid communication with the inflation button has a center element which is rotatable in a cup-shaped elastomeric fixed element. A flange in the fixed element cooperating with a groove in rotatable element holds the rotatable element in place. The fixed element is made of elastomeric material such as silicone rubber which is forced by internal pressure into fluid tight relationship with the rotating element. Silicone fluid is optionally placed between the two elements to further effect positive sealing. As an alternate, an integral inflation button may be built into the rotatable element to allow the surgeon a choice of inflation sites.
