An external catheter, and the methods of making and using such a catheter, for a male urinary incontinence collection system, such system also including an adhesive attachment for holding the catheter in place. The catheter takes the form of a tubular sheath of thin elastic material having a cylindrical body section, a tapered neck section extending from the body section, and a reduced drainage tube section projecting from the neck section. Within the sheath, and constituting a unitary part thereof, is a tubular inner sleeve of soft elastic material having a distal end portion diposed within the neck section and a proximal end portion merging with the sheath's cylindrical body section. The sleeve tapers distally to define an annular space thereabout, and terminates in a reduced distal opening located at an intermediate point within the neck section. The sheath may be produced by a dipping process that includes the preliminary step of stretching a pre-formed tubular member (which ultimately forms the inner sleeve) over a dipping form, followed by successive dipping steps.
