Abstract: A washer for protecting a flange. The washer is capable of withstanding high compression loads, protecting a flange plate from galvanic corrosion, and maintaining torque load when a flange joint is exposed to extreme heat. The washer has two primary components—an inner ring and an outer ring—that are preferably made of materials having dielectric properties, particularly with respect to electrical insulation. The inner ring and outer ring are preferably fit together using an interference fit.

Abstract: A casing spacer equipped with low-profile, high-load-capacity roller assemblies that require less force to install a carrier pipe inside a casing pipe. The low-profile, high-load-capacity roller assemblies are manufactured from a material designed to carry a heavy load, which material will not wear away as the carrier pipe is pushed or pulled through the casing pipe. The wheels of the low-profile, high-load-capacity roller assemblies are manufactured from an electronically isolating material to prevent contact of dissimilar metals, thereby mitigating galvanic corrosion.

Abstract: A gasket that is capable of withstanding high compressive cads, protecting a flange joint from galvanic corrosion, and preventing fluids from leaking through a flange joint when the flange joint is exposed to extreme heat.

Abstract: A casing spacer which allows for the positioning of a carrier pipe or set of carrier pipes in a desirable location inside a casing pipe.

Abstract: Antithrombotic agents having reactional functional groups are reacted with a base polymer also having reactive functional groups to form a surface coating for a medical material. The medical materials are used in medical devices in contact with blood or blood products such as artificial hearts, heart lung machines, pacemakers, vascular graft tubing, intra-aortic balloons, blood bags, soft or hard tissue prostheses, catheters, sutures, artificial organs, and the like.

Abstract: Provides antithrombotic agents which can be bonded to plastic to provide thromboresistant materials and a method for performing the bonding process. Further provides thromboresistant materials for medical devices used in contact with blood or blood products such as artificial hearts, heart lung machines, kidney dialysis machines, dialysis exchangers, pacemakers, vascular graft tubing, microporous membrane blood oxygenators, intra-aortic balloons, ultra-filtration membranes, blood bags, soft or hard tissue prostheses, cathaters, sutures, artificial organs, and the like.
