Abstract

"SISTEMA E MéTODO PARA DESFIBRILAR UM CORAçãO HUMANO E PARA AUXILIAR O CORAçãO A BOMBEAR". Um sistema de suporte cardíaco inclui um dispositivo de auxílio cardíaco adaptado para ser estendido sobre uma porção do coração de um paciente para auxiliar os ventrículos do coração a se contraírem corretamente. Um ou mais eletrodos estimuladores (74) são montados no dispositivo de auxílio ventricular em localizações selecionadas tal que quando o dispositivo de auxílio ventricular for estendido sobre o coração, os eletrodos de estimulação estejam em vizinhança próxima à superfície do coração. O sistema adicionalmente inclui um ou mais eletrodos coletores externos (70) que recebem energia aplicada externamente, e conduzem aquela energia a um ou mais eletrodos estimuladores via terminais condutores (72). Os eletrodos coletores externos (70) podem ser montados na superfície externa do dispositivo de auxílio ventricular, ou podem ser localizados em alguma outra localização dentro do corpo do paciente. A energia aplicada externamente será tipicamente fornecida por pás de desfibrilação padrões localizadas fora do corpo do paciente. Em lugar dos eletrodos coletores, os eletrodos estimuladores podem ser conectados diretamente a, respectivamente, uma fonte de energia elétrica, e uma placa de aterramento.
