A male urinary catheter and method of making same. The catheter employs a condom like sheath of silicone rubber which sealingly engages the penis of the patient. A catheter stem at the distal end of the sheath couples to a urine collection system. The sheath is sealed to the penis by an adhesive which is applied to the outer surface of the sheath at the time of manufacture. A surface preparation layer is applied over the adhesive. The sheath is rolled up from the proximal end. The sheath is unrolled to apply it to the patient. During the unrolling process, the adhesive layer is removed from the outer surface and deposited on the inner surface of the sheath.

[ We claim:] [1.] A method of manufacturing an external male catheter, said external male catheter having an exterior surface, an interior surface, a distal end, and a proximal end, said method comprising the steps of:dipping a form mandrel into silicone rubber to produce a substrate defining the interior surface and the exterior surface of the external male catheter;precuring said substrate;applying an adhesive layer to a predetermined region of the exterior surface of the substrate;curing at least the adhesive layer or the substrate;applying a surface preparation material overlying the adhesive layer, said surface preparation material having an affinity for the silicon rubber which is greater than that of the adhesive layer; androlling the substrate upon itself from the proximal end toward the distal end to a rolled configuration such that a portion of the interior surface lies in close confronting relation to a distinct region of the interior surface, the surface preparation material contacting the distinct region of the interior surface of the substrate with the adhesive layer being transferred directly to the interior surface from the exterior surface.
