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 disposed 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.
A method of securing an external male catheter upon a wearer to protect surfaces of the glans against injury from direct urine contact while at the same time avoiding objectionable adhesive engagement between the catheter and the glans, comprising the steps of providing an external catheter having a tubular sheath formed of soft elastic material and including a thin-walled cylindrical body section, a reduced drainage tube section, a tapered neck section disposed between said body and drainge tube sections, and an inner sleeve of soft elastic disposed within said sheath and having a proximal end portion merging and permanently integrated with said cylindrical section and an elongated distal end portion extending and tapering distally into said neck section;
The method of c1aim 1 in which said step of adhesively securing said cylindrical body section of said sheath to the shaft of the penis comprises first coating at least a portion of the interior surface of said cylindrical body section with a pressure-sensitive adhesive before fitting said catheter upon the wearer.
