Implantable medical catheter having reinforced silicone elastomer composition

   
   

An implantable medical catheter comprising at least one fluid passageway and a cured elastomer composition is disclosed. The cured elastomer composition is obtained by cross-linking an uncured blend composition that comprises an intimately admixed mixture that comprises the following components: (A) silica that had been silyliated by treatment and contains trialkylsilyl groups; (B) a polysiloxane copolymer; (C) a catalyst, and (D) an organohydrogen polysiloxane cross-linker, the catalyst and the cross-linker being present in the uncured blend composition in sufficient amount to cause the cross-linking reaction to occur.

Показан implantable медицинский катетер состоя из по крайней мере одного жидкого переходного люка и вылеченного состава эластомера. Вылеченный состав эластомера получен cross-linking uncured состав бленды состоит из плотно подмешенной смеси состоит из following компонентов: (A) кремнезем был silyliated обработкой и содержит группы trialkylsilyl; (B) сополимер polysiloxane; (C) катализатор, и (D) cross-linker polysiloxane organohydrogen, катализатор и cross-linker присутствуя в uncured составе бленды в достаточно количестве причинить реакцию cross-linking произойти.
