Abstract

aparelho de liberação e método associado um aparelho de liberação para liberar uma carga a um local alvo do tecido corporal interno é fornecido. o aparelho de liberação compreende um membro tubular flexível tendo uma extremidade distal adaptada para inserção próxima ao local alvo. um primeiro eletrodo é configurado para inserção dentro do membro tubular flexível tal que o primeiro eletrodo é capaz de ser disposto próximo ao local alvo. um segundo eletrodo é configurado para cooperar com o primeiro eletrodo para formar um campo elétrico. um componente de liberação tem desse modo uma carga carregada e é acoplado com o primeiro eletrodo. o componente de liberação é configurado para degradar quando exposto ao campo elétrico tal que a carga é liberada ao local alvo sob degradação do mesmo. um método associado é também fornecido.
