Abstract

A lubricious coating including at least one ethylenically unsaturated resin and at least one hydrophilic aliphatic polyether polyurethane which does not crosslink with said ethylenically unsaturated resin, and to methods of making and using the same.

Claims (22)

1 - 41 . (canceled)

42 . A catheter assembly comprising at least one catheter shaft having a proximal end and a distal end, the catheter shaft formed from a first polymer composition, and at least one expandable balloon member disposed about the distal end of the catheter shaft, the expandable medical balloon member formed from a second polymer composition, at least a portion of the catheter assembly comprising a lubricious coating, the lubricious coating formed from a third polymer composition different than the first and second polymer compositions, the third polymer composition is an interpenetrating or semi-interpenetrating polymer network comprising at least one ethylenically unsaturated resin and at least one hydrophilic thermoplastic aliphatic polyether polyurethane wherein the lubricious coating is cured.

43 . The catheter assembly of claim 42 wherein said thermoplastic aliphatic polyether polyurethane is substantially uncrosslinked.

44 . The catheter assembly of claim 42 wherein said expandable medical balloon comprises said lubricious coating.

45 . The catheter assembly of claim 44 wherein said expandable medical balloon is formed from poly(ether-block-amide).

46 . The catheter assembly of claim 42 wherein said hydrophilic thermoplastic aliphatic polyether polyurethane absorbs about 500% to about 2000% of its own weight in water upon exposure to an aqueous environment.

47 . The catheter assembly of claim 42 wherein said at least one ethylenically unsaturated resin comprises functional groups which are activated photochemically.

48 . The catheter assembly of claim 42 further comprising at least one photoinitiator.

49 . The catheter assembly of claim 42 wherein said at least one ethylenically unsaturated resin comprises functional groups which are activatable by ultraviolet radiation.

50 . The catheter assembly of claim 42 wherein said at least one ethylenically unsaturated resin comprises at least one member selected from the group consisting of mono-, di- and tri-acrylates, polyacrylates and mixtures thereof.

51 . The catheter assembly of claim 42 wherein said at least one ethylenically unsaturated resin is a diacrylate.

52 . The catheter assembly of claim 50 wherein said at least one ethylenically unsaturated resin comprises at least one member selected from the group consisting of butyl (meth)acrylate, methyl (meth)acrylate, ethyl (meth)acrylate, propyl (meth)acrylate, octyl (meth)acrylate, heptyl (meth)acrylate, nonyl (meth)acrylate, hexyl (meth)acrylate, n-hexyl (meth)acrylate, isopropyl (meth)acrylate, isobutyl (meth)acrylate, decyl (meth)acrylate, isodecyl (meth)acrylate, lauryl (meth)acrylate, stearyl (meth)acrylate, behenyl (meth)acrylate and melissyl (meth)acrylate, methoxyethyl (meth)acrylate, hydroxyl ethyl (meth)acrylate, glycidyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, 2-ethoxyethyl (meth)acrylate, ethylene glycol di(meth)acrylate, propylene glycol di(meth)acrylate, diethylene glycol di(meth)acrylate, polyethylene glycol di(meth)acrylate, 1,5-pentanediol di(meth)acrylate, neopentyl glycol di(meth)acrylate (NPG), 1,6-hexanediol (meth)acrylate, 1,6-hexandiol di(meth)acrylate, polyethylene glycol di(meth)acrylate, polypropylene glycol di(meth)acrylate, pentaerythritol tri(meth)acrylate, trimethylolpropane tri(meth)acrylate, trimethylolpropane dipentaerythritol penta(meth)acrylate, pentaerythritol tetra(meth)acrylate, triethylene glycol di(meth)acrylate, n-butyl (meth)acrylate, benzoin (meth)acrylate, glyceryl propoxy tri(meth)acrylate, 1,3-propylene glycol di(meth)acrylate, tripropylene glycol di(meth)acrylate, 1,3-butylene glycol di(meth)acrylate, 1,4-butanediol di(meth)acrylate, 1,6-hexanediol di(meth)acrylate, diethylene glycol di(meth)acrylate, triethylene glycol di(meth)acrylate, tetraethylene glycol di(meth)acrylate, methyl ethacrylate, ethoxylated bisphenol-A-di(meth)acrylate and mixtures thereof.

54 . A guide wire comprising a lubricious coating, the lubricious coating is an interpenetrating or semi-interpenetrating polymer network comprising at least one ethylenically unsaturated resin and at least one hydrophilic thermoplastic aliphatic polyether polyurethane wherein the lubricious coating is cured.

55 . The guide wire of claim 54 wherein said hydrophilic thermoplastic aliphatic polyether polyurethane absorbs about 500% to about 2000% of its own weight in water upon exposure to an aqueous environment.

56 . The guide wire of claim 54 wherein said at least one ethylenically unsaturated resin comprises functional groups which are activated photochemically.
