A medical device wherein the device has an outer surface coated with an oleophilic lubricous coating or the device is formed from a mixture including a polymer and an oleophilic compound.
Opening claim text (preview).
1 . A urinary catheter, comprising: a catheter tube having an outer surface; and a lubricious coating comprising one or more oleophilic compounds disposed on the outer surface of the catheter tube. 2 . The urinary catheter of claim 1 wherein the catheter tube is comprised of a water degradable polymer. 3 . The urinary catheter of claim 2 wherein the water degradable polymer is polyvinyl alcohol. 4 . The urinary catheter of claim 1 wherein the catheter tube is comprised of one or more of polyvinyl chloride, polyurethane, ethylene-co-vinyl acetate-co-maleic anhydride and ethylene-co-vinyl acetate. 5 . The urinary catheter of claim 1 wherein the oleophilic compound comprises one or more of glycerol monooleate, oleoyl-rac-glycerol, glycerol tri-oleate, oleic acid and oleyl alcohol or their mixtures. 6 . The urinary catheter of claim 1 wherein the catheter has a coefficient of friction of less than about 0.45, preferably less than about 0.3 and more preferably less than about 0.2. 7 . The urinary catheter claim 1 wherein the coating is coated onto the outer surface of the catheter tube. 8 . The urinary catheter of claim 1 wherein the coating is dip coated onto the outer surface of the catheter tube. 9 . A sterilized lubricated urinary catheter, comprising a catheter tube having an outer surface; a coating comprising one or more oleophilic compounds disposed on the outer surface of the catheter tube; and wherein the coating and catheter tube are sterilized. 10 . The sterilized lubricated urinary catheter of claim 9 wherein the catheter tube is comprised of a water degradable polymer. 11 . The sterilized lubricated urinary catheter of claim 10 wherein the water degradable polymer is polyvinyl alcohol. 12 . The sterilized lubricated urinary catheter of claim 9 wherein the catheter tube is comprised of one or more of polyvinyl chloride, polyurethane, ethylene-co-vinyl acetate-co-maleic anhydride and ethylene-co-vinyl acetate. 13 . The sterilized lubricated urinary catheter of claim 9 wherein the oleophilic compound comprises one or more of glycerol monooleate, oleoyl-rac-glycerol, glycerol tri-oleate, oleic acid and oleyl alcohol or their mixtures. 14 . The sterilized lubricated urinary catheter of claim 9 wherein the coating is coated onto the outer surface of the catheter tube. 15 . The sterilized lubricated urinary catheter of claim 9 wherein the coating and catheter are sterilized by e-beam, gamma, steam, microwave or ethylene oxide. 16 . The sterilized lubricated urinary catheter of claim 9 wherein the coating and catheter tube are sterilized with between about 20 kGy and about 40 kGy of gamma radiation. 17 . The urinary catheter of claim 2 wherein the coating delays substantial dissolution of the catheter. 18 . The urinary catheter of claim 2 wherein a coating containing one or more oleophilic compounds is applied to an inner lumen of the catheter and the coating delays substantial dissolution of the catheter. 19 .- 26 . (canceled) 27 . A catheter, comprising: a catheter tube at least partially formed from a mixture comprising an oleophilic compound and a polymer wherein the oleophilic compound is in an amount of about 0.5 percent by weight (wt. %) to about 20 wt. % of the mixture. 28 .- 55 . (canceled)
