  • Methods and devices for electrosurgery
    Patent number: 6902564
    Abstract: Method and devices for electrosurgery by means of oxy-hydro combustion. Deleterious effects to tissue are minimized by means of control of acid-base shift reactions, which reactions can further be employed to control oxy-hydro combustion reactions. In one embodiment, radiofrequency energy in electrical connection with electrodes is employed to induce electrolysis in an aqueous salt environment, thereby producing oxygen and hydrogen, with the same energy source employed to initiate a combustion reaction.

  • Compositions prepared using finely-divided isocyanate based thermoset polymers
    Patent number: 5342884
    Abstract: Compositions comprising a non-isocyanate based thermoplastic polymer and a finely divided isocyanate based thermoset polymer are disclosed. The compositions can optionally further comprise an adhesive thermoplastic compatibilizing agent. Finely divided scrap isocyanate based thermoset polymer materials can be used in preparing these compositions, thus lowering manufacturing and disposal costs. A method to prepare these compositions is also disclosed.

  • Reaction injection molded polyurethanes having particular flexural modulus factors and at least two thermal transition temperatures in a particular range
    Patent number: 4246363
    Abstract: Polyurethane reaction injection molded products are prepared which have flexural modulus factors (-20.degree. F./158.degree. F.) below 3.4 and often below 2. They are prepared by employing three different polyols or mixtures of polyols, each polyol having a specified reactivity relationship and are employed within specified solubility parameter relationships. These products also have at least two thermal transition temperatures.
