Abstract: Disclosed is an apparatus and method to facilitate insertion of the endotracheal tube into the patient's trachea.

Abstract: A self-sealing vascular graft, including a substrate with a sealant layer and several optional additional layers, is described. The substrate can be ePTFE and the material used for the sealant and additional layers can be polyurethane. The sealant layer and additional layers may include one or more base layers, one or more foam layers, beading of different sizes and shapes, and ePTFE tape. A flared cuff may be integral to one or both ends of the substrate or may be attached to one or both ends. Various methods of making a self-sealing vascular graft are also described, including methods of disposition, methods of forming, methods of bonding and methods of attaching.

Abstract: A cook fan to prevent boiling over in a cooking container including a base that allows the cook fan to be placed near the cooking container; a fan attached wherein the fan further comprises a motor and blades attached to the motor; and a connector member attached to the base and the fan, wherein the connector member allows the position of the fan to be adjusted.

Abstract: A flexible, kink-resistant, low-friction guidewire for positioning a medical instrument through tortuous passageways within a patient is disclosed. The guidewire includes a core wire which remains substantially free of any residual strain when it is positioned within the patient, a metal coil about the core wire and extending substantially the entire length of the core, a primer coating on the coil and a hydrophilic, lubricous coating on the primer coating. The core wire is preferably a superelastic metal alloy such as Nitinol. The metal coil is preferably formed from a wire with a rectangular cross section. The primer is preferably one which reacts with species of isocyanate or hydroxyl, and the hydrophilic, lubricous coating is preferably a cross-linked polymer selected from the group of polyurethane, polyurea, and polyurethaneurea, complexed with a hydrophilic complexing species such as poly(ethylene oxide) or polyvinylpyrrolidone. A method for manufacturing and coating such a guidewire is also disclosed.

Abstract: A two step method or process for improving the adherence or bonding of a lubricious coating of a crosslinked polyurethane, polyurea or polyurethaneurea/PEO or PVP coating to a substrate surface, said two step method comprising a first step of subjecting said surface to a surface preparation which results in the treated surface being provided with a functional tie layer containing functional groups for reaction with functional groups of a reaction mixture to be applied in a subsequent second step, which upon curing forms a crosslinked polyurethane, polyurea or polyurethaneurea/PEO or PVP coating and a second step of applying to said tie layer said reaction mixture and curing the reaction mixture. A medical device resulting from the above-described two step method.
