Granted: 2016-04-11
Abstract: Sistema de amortiguación para prótesis de rodilla y cadera.#Actualmente, las prótesis de rodilla y cadera siguen manteniendo el diseño y materiales de hace 30 años, modificando ligeramente rugosidades y diseño. Sin embargo, a día de hoy en la sociedad ha aumentado tanto la esperanza de vida como el número de incidencias en artroplastia a una edad cada vez más joven. Por ello, se hace necesario crear nuevas prótesis con efecto amortiguador de impactos o tensiones características, tanto máximas como de rutina, modificando el componente de polietileno. Con ello, se pretende minimizar el desgaste del material por fatiga, gracias a la capacidad de absorción de energía del componente de desarrollo, alargando al paciente una cirugía de revisión de su prótesis. Para ello, se ha previsto que el inserto (1) incorpore uno o más vaciados interiores (2-2-2-2-2{sup,IV}-2{sup,V}-2{sup,VI}) como elemento de amortiguación, que pueden estar parcial o totalmente rellenos de un material polimérico biocompatible amortiguador.

Inventor: WAN CHUNG-ZONG
IPC: B01J37/02
Filed: 1987-06-26
Granted: 1995-03-15
Abstract: A method of making a catalyst composition comprising an activated alumina coating stabilized against thermal degradation includes applying a coating of alumina having one or more platinum group metal catalytic components dispersed thereon onto a carrier substrate and calcining the coating. The calcined coating is then impregnated with a solution of a thermal stabilizer-precursor and calcined again to provide a thermal stabilizer in the alumina. Bulk ceria, optionally an aluminum-stabilized bulk ceria, may also be added to the composition, preferably at specified minimum levels, including a high purity bulk ceria on which one or more non-rhodium platinum group metal catalytic components, e.g., platinum, optionally, are dispersed. A separate aspect of the invention provides for a method of making a catalyst composition including dispersing one or more platinum group metal catalytic components on an activated alumina and calcining the combined alumina and platinum group metal catalytic components. The steps are carried out under limited acidification conditions whereby at least minimum dispersions of the platinum group metal catalytic components are attained. The invention also provides for catalyst compositions resulting from either or both the foregoing methods.
