Patent ID: 7309519

Claim:
A medical drape comprising: a backing layer having a first surface and a second surface, where projecting from the first surfane of the backing layer is a soft and flexible array of stems which are integrally formed with the backing layer; wherein at least a portion of the exterior surface of the stems comprises an elastomeric material selected from the group consisting of anionic triblock copolymers; thermoplastic elastomers based on halogen-containing polyolefins; thermoplastic elastomers based on dynamically vulcanized elastomer-thermoplastic blends; thermoplastic polyether ester and polyester based elastomers; thermoplastic elastomers based on polyanaides or polyimides; jonomeric thermoplastic elastomers; hydrogenated block copolymers in thermoplastic elastomer interpenetrating polymer networks; thermoplastic elastorners made by carbocationic polymerization; polymer blends containing styrene/hydrogenated butadiene block copolymers; polyacrylate-based thermoplastic elastomers; natural rubbers; butyl rubbers; EPDM rubbers; silicone rubbers; polyisoprenes; polybutadienes; polyurethanes; ethylene/propylene/diene terpolymer elastomers; chloroprene rubbers; random and block styrene-butadiene copolymers; random and block styrene-isoprene copolymers; acrylonitrile-butadiene copolymers; and mixtures and copolymers thereof; wherein the aspect ratio of the stems on the first surface of the backing layer is at least about 1.25; and wherein the drape has a static coefficient of friction when dry along at least a portion of the first surface of at least 0.6.
