ABSTRACT:
Securement of a condom to the glans penis is facilitated by a molded, contoured, or thickened wedge portion which fits snugly within the cleft of the glans such that a continuous circumferential seal may be obtained about the glans penis. An expansible seminal reservoir is provided and the shaft of the penis, as well as the rear portion of the glans penis opposed to the cleft, may be left unsheathed in order to allow greater sensitivity. A greater wall thickness than that typically utilized in a full length condom may be used without significant loss of sensitivity and a stronger condom more resistant to tearing during use than a conventional full length latex condom is obtained. An adhesive backing with a tab allows location of the device prior removal of the backing to ensure correct positioning and an effective circumferential seal with the adhesive. Regardless of whether or not the entire corona of the glans is encompassed a wedge shaped structure fitting in the cleft between the two lobes of the glans is utilized to obtain an anatomically accurate interior annular surface which is recommended for bearing an adhesive layer though an elastic band may be utilized in the case the entire corona is encompassed.
