Abstract
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.
