A coating composition is disclosed which comprises an aqueous polymeric matrix, a hydrophilic polymer, a colloidal metal oxide and a crosslinker. The coating composition when applied on medical devices is hydrophilic, shows improved lubricity, abrasion resistance and substrate adhesion on metallic or plastic substrates. The coating also shows improved water sheeting thus providing the coated substrates with anti-fog properties. The coating absorbs aqueous dye or stain solutions making the substrate suitable for printing.

A high strength abrasion resistant surgical suture material with improved tie down characteristics is color coded for visualization and identification purposes. The suture features a multifilament cover formed of strands of ultra high molecular weight long chain polyethylene braided with polyester, nylon or a bioabsorbable material. Selected nylon fibers in the cover are provided in a color contrasting with the other cover fibers to provide an identifiable trace. The cover surrounds a core formed of twisted strands of ultrahigh molecular weight polyethylene. The suture, provided in a #2 size, has the strength of #5 Ethibond, is ideally suited for most orthopedic procedures, and can be attached to a suture anchor or a curved needle. The identifiable trace preferably is provided along one half of the length of the suture, so that when the suture is loaded onto a suture anchor, for example, the two legs of the length of suture on either side of the suture anchor can be readily identified.

A surgical access device includes a single valve that forms a seal with the body wall and provides an access channel into a body cavity. The valve has properties for creating a zero seal in the absence of an instrument as well as an instrument seal with instruments having a full range of instrument diameter. The valve can include a gel and preferably an ultragel comprised of an elastomer and an oil providing elongation greater than 1000 percent and durometer less than 5 Shore A. The single valve can be used as a hand port where the instrument comprises the arm of a surgeon, thereby providing hand access into the cavity. A method for making the surgical access device includes the combining of a gelling agent with an oil, preferably in a molding process. A method for using the device includes steps for creating an opening with the instrument. In a particular process, an organ can be removed from the body cavity through the single valve to create an organ seal while the organ is addressed externally of the body cavity. The valve and method are particularly adapted for laparoscopic surgery wherein the abdominal cavity is insufflated with a gas thereby requiring the zero seal, the instrument seal, and the organ seal in various procedures.

Methods for treating female sexual dysfunction are provided. A pharmaceutical composition containing a vasoactive agent selected from vasoactive intestinal potypeptide (VIP) and VIP agonists is administered to the vagina and / or vulvar region of the individual undergoing treatment. The formulations are also useful for improving vaginal muscle tone and tissue health, enhancing vaginal lubrication, and minimizing excess collagen deposition. Pharmaceutical formulations and kits are also provided.
