Abstract

Se proporciona un dispositivo (10) para insertar instrumentos medicos, como cables de marcapasos, en un paciente. El dispositivo (10) incluye una aguja flexible (30) con una punta puntiaguda rodeada por un manguito (40) y un cateter (50). Un elemento de desviacion desvia la aguja (30) hacia una posicion en la cual la punta de la aguja es encerrada dentro del manguito (40). Tambien se proporciona un metodo para insertar un instrumento medico, como un cable de marcapasos, en el cual la aguja (30) es insertada en un paciente, seguida por el manguito (40) y el cateter (50). La aguja (30) se retrae entonces de modo que la punta puntiaguda sea encerrada dentro del manguito (40). La aguja (30) permanece en el manguito (40) cuando el manguito (40) y el cateter (50) se curvan en alineacion con un vaso sanguineo y avanzan a traves del vaso sanguineo. La aguja (30) y el manguito (40) son entonces jalados hacia fuera, y un cable de marcapasos u otro instrumento es alimentado a traves del cateter (50) y hacia el vaso.
