Abstract: A method for introducing a urinary catheter of a urinary catheter package, the urinary catheter package including a grip designed for sliding movement over the urinary catheter. The grip can include a body designed to surround the urinary catheter shaft, a first flare, and a second flare. The body can include a proximal end, a distal end, and a gripping area between the proximal end and the distal end, the gripping area designed to contact the urinary catheter upon the application of force to the gripping area. The first flare can increase in cross-sectional area from the gripping area to the proximal end of the body. The second flare can increase in cross-sectional area from the gripping area to the distal end of the body. The method includes removing the urinary catheter from a proximal end of the urinary catheter package.

Abstract: The invention relates generally to external urinary catheters for males. More specifically, the invention relates to an external urinary catheter that includes an absorbent material to absorb urinary discharge. The absorbent material can be located in either a distal end of a tubular sheath, or in a receptacle that attached to the distal end of the tubular sheath. The tubular sheath of the external urinary catheter can include a tubular sheath of silicone rubber, wherein the sheath has an inner surface and an outer surface, and a layer of adhesive material directly and non-releasably bonded to the inner surface.

Abstract: A sustained release antimicrobial cannula or catheter for residence within a portion of a human body through which aqueous biological fluids can pass and including a tube. The tube has a polymeric matrix and an antimicrobial agent residing within at least a portion of the polymeric matrix. The polymeric matrix includes cured silicon rubber and the antimicrobial agent is a finely divided nitrofuran compound, a paraben antifungal, or combinations thereof. The antimicrobial agent can diffuse out of the polymeric matrix and into an aqueous biological environment when the polymeric matrix comes into contact with such an aqueous biological environment. Methods of making a sustained release antimicrobial cannula and of catheterizing a patient are also disclosed.

Abstract: The invention relates to a Foley-type catheter constructed to prevent the retention balloon from cuffing, and methods of making the same. In an embodiment, the invention relates to a catheter including an additional sheath layer over the outside surface of the catheter and methods of making and using the same. The catheter includes a central layer that defines a first lumen and a second lumen. The catheter further includes a balloon layer surrounding the central layer and a balloon cavity disposed between the exterior surface of the central layer and the balloon layer. A sheath layer surrounds the balloon layer and extends over the balloon cavity. In an embodiment, the invention relates to a catheter with a retention balloon including ribs and methods of making and using the same. The catheter includes a central layer defining a first lumen and a second lumen and a sheath layer surrounding the central layer. The catheter further includes a balloon cavity.

Abstract: A method shaping polymeric structures by coating a support structure with a bond-preventing agent to attain a particular shape and subsequently coating the shaped structure of the bond-preventing agent with a polymeric bonding composition is provided. Such shaped polymeric structures can have one or more cavities which can be fluid-filled or gel-filled. Also provided is a hand-actuating retention female urinary catheter having an inner tube and an outer overcoat layer encircling the tube with an elastomeric collar with a shroud. A cavity containing a fluid is interposed between the tube and the overcoat layer. The cavity includes a balloon portion and a reservoir portion. The shroud encircles the reservoir section to inhibit the ballooning of the reservoir section when the reservoir section is squeezed to force fluid from the reservoir portion to the balloon portion through the sleeve portion of the cavity. The overcoat layer and the collar with a shroud are made of soft resilient material.

Abstract: An apparatus for sealing at least a portion of the urinary tract to prevent the unwanted discharge of urine includes a body member with a tubular member, encircled along its length by an overcoat layer, that encases a fluid, forming a cavity. The body member, with its tubular member and overcoat layer are elastically deformable from an initial “rest” or “relaxed” state, when outside of the body, where at least a portion of the overcoat layer is of a diameter equal to or greater than that of an undilated urethra. A stylet may be placed into the tubular member to serve as a guide, for elongation of the body member and to provide rigidly to the body member upon insertion into the urinary tract. There is also disclosed a method for making the apparatus of the present invention.
