ESTIMULAÇÃO MECÂNICA NA INTERFACE OSSO/IMPLANTE POR ACTUADORES PIEZOELÉCTRICOS
Reis, Joana; Frias, Clara; Capela e Silva, Fernando; Potes, José; Canto e Castro, Carlos; Botelho, Maria Luísa; Simões, José AntónioEste trabalho descreve os resultados da implantação em tíbia e fémur de ovelha de actuadores piezoeléctricos, pelo efeito piezoeléctrico inverso. A estimulação mecânica assim conseguida teve forte impacto na área ocupada por osso, bem como na taxa de mineralização.
Sterilization of an Electronical Medical Device
Reis, Joana; Cabo Verde, Sandra; Capela Silva, Fernando; Potes, José; Melo, Rita; Nunes, Inês; Marcos, Helena; Silva, Telma; Botelho, Maria LuísaRadiosterilization was applied to a medical device with a “programmable memory” to allow in vivo implantation. Irradiation on a Cobalt-60 facility at 25 kGy at a dose rate of 2kGy/h corrupted the memory. Therefore an alternative sterilization method using UV was developed and validated based on ISO 11737-1 and ISO 14937. These procedures may be useful and effective for research purposes when only a small number...
