Disclosed are high strength polyurethane foam compositions and methods of making them. In one aspect, the inventive polyurethane foams include strength enhancing additives comprising one or more polycarbonate polyols derived from the copolymerization of COand one or more epoxides. In one aspect, the inventive methods include the step of substituting a portion of the polyether polyol in the B-side of a foam formulation with one or more polycarbonate polyols derived from the copolymerization of COand one or more epoxides.

High strength polyurethane foam compositions and methods

This invention relates to biodurable, reticulated elastomeric matrices that are resiliently-compressible, their manufacture and uses including uses for implantable devices into or for topical treatment of patients, such as humans and other animals, for therapeutic, nutritional, or other useful purposes.

Reticulated elastomeric matrices, their manufacture and use in implantable devices

Methods of performing medical procedures, and methods of making bone-growth-promoting compositions useful in performing medical procedures are provided. Apparatus useful both in methods of performing medical procedures, and in methods of making bone-growth-promoting compositions useful in performing medical procedures, are provided. The bone-growth-promoting compositions made according to the disclosed methods are biocompatible, and are adapted to stimulate bone growth when positioned in contact with, or in the vicinity of, a bone of a mammal.

An article comprising two or more layers. One or more of the layers includes of a polymeric foam tape containing one or more curable resins. One aspect of the present invention is to use the article as an orthopedic casting splint.

Foam articles

An article including a polymeric foam having a thickness of less than about 3/16 inch (about 5 mm) and one or more curable resins.

An orthopedic casting article comprising a polymeric foam tape containing one or more curable resins. The polymeric foam tape can be a foam having a substantially open cell structure, substantially closed cell structure, or a substantially reticulated cell structure. The curable resin can be a water-curable resin. The casting article can be multi-layered to obtain an article suitable for splinting applications.

Orthopedic casting articles

One aspect of the present invention is a casting article comprised of a water-curable Plaster of Paris (PP) article having a first side and a second side and having a substrate and PP material and a polyisocyanate material being applied to at least one of the first and second sides of the water-curable PP to obtain a water-curable hybrid plaster-polyisocyanate (HPP) casting article.

Disclosed is a new class of TPUs with improved properties, based on poly(1,3-propanediol carbonate) diol, using 10 to 55% hard segment concentration, and cured with a diisocyanate. The composition provides a broader range of mechanical and thermal properties for TPU formulations, including improvements in hardness, higher elasticity modulus, and improved softening temperature and coefficient of thermal expansion, in addition to improved clarity.

Thermoplastic polyurethane elastomers (TPUs) prepared with polytrimethylene carbonate soft segment

An article of manufacture for load bearing medical use such as a joint implant suitable for total joint replacement. The article comprises a polyurethane-containing component and is monolithic with respect to polyurethane-containing component(s). The joint for long term load applications is structurally an articulated joint and the polyurethane component provides a surface for articulation with the polyurethane.

Polyurethane and so forth containing joints

Thermoplastic polyurethanes are formed from a hydrogenated polydiene diol having from 1.6 to 2 terminal hydroxyl groups per molecule and a number average molecular weight between 500 and 20,000, an isocyanate having two isocyanate groups per molecule, and optionally a chain extender having two hydroxyl groups per molecule. The thermoplastic polyurethanes have excellent resistance to moisture as evidenced by retention of more than 70%, preferably at least 85%, of original tensile strength after aging in water for 7 days at a temperature of at least 70.degree. C. Preparation by a prepolymer method with subsequent addition of the chain extender is preferred.
