A tubular elastic sheath for a condom catheter, the sheath taking the form of a thin, flexible, cylindrical member of elastic material having inner and outer surfaces and being rolled outwardly upon itself to form a torus having successively larger turns. A thin, flexible, multi-layered tape is interposed between successive turns of the rolled torus with such layers, all adhering to each other and to the catheter member, comprising a first adhesive layer, a second adhesive layer, and a highly-stretchable elastomeric layer disposed between the first and second adhesive layers. The first adhesive layer adheres to the inner surface of the catheter member and the second adhesive layer adheres to the outer surface of that member, and the relationship is such that the elastomeric layer adheres more securely to the second adhesive layer than to the first adhesive layer, and the first adhesive layer has less affinity for the elastomeric layer than each of the adhesive layers has for the surfaces of the catheter member. As a result, when the sheath is unrolled, the tape undergoes delamination with the first adhesive layer remaining upon the sheath\s inner surface and the second adhesive layer, covered by the elastomeric layer, remaining on the sheath\s outer surface.

A sheath for a condom catheter, said sheath comprising a thin, flexible cylindrical member of elastic material having inner and outer surfaces and being rolled outwardly upon itself to form a torus having successively larger turns; and a thin, flexible, delaminateable tape means interposed between successive turns of said rolled torus and having multiple layers adhering to each other; said layers comprising a first adhesive layer, a second adhesive layer, and a highly-stretchable elastomeric layer disposed between said first and second adhesive layers and having a smooth, non-tacky outer surface; said first adhesive layer being adhered to said inner surface of said member and said second adhesive layer being adhered to said outer surface of said member; said elastomeric layer being adhered more securely to said second adhesive layer than to said first adhesive layer and said first adhesive layer having less affinity for said elastomeric layer than each of said adhesive layers has for the surfaces of said member; said tape means undergoing delamination with said first adhesive layer remaining upon the sheath\s inner surface for securing the sheath to a wearer and said second adhesive layer, covered by said elastomeric layer, remaining on the sheath\s outer surface, when said sheath is unrolled over a wearer\s penis.
