Abstract
Abstract A retromammary prosthesis is formed of pre-moulded flexible sheet material in two major portions which are connected along an annular area such that, when the prosthesis is positioned within the body, the area of connection is not deformed by filling of the prosthesis and does not give rise to discomfort to the wearer. In a preferred form, a filler tube for the prosthesis is connected to the remainder by means of a housing which may be inverted so as to lie wholly within the prosthesis and receive the entire filler tube in folded condition.

A retromammary prosthesis comprising, a front wall preformed as a portion of a hollow sphere with its rim portion curved inwardly from the outer periphery thereof and into the concavity thereof and terminating therein in an annular flange, a circular rear wall of smaller diameter than said rim secured at its periphery to the annular flange and preformed to curve inwardly, the central portion of the rear wall being provided with a hollow protuberance, an elongated flexible filler tube of smaller width than said protuberance, secured to said protuberance and opening into said concavity, said hollow protuberance extending into said concavity to provide a predetermined volume of hollow space, said filler tube being of a length to extend from the prosthesis when located between the chest muscle and mammary gland of a wearer, to a location exterior of the breast, the hollow space provided by the protuberance being sufficient to house the entire flexible filler tube in folded condition.
