Abstract

Se divulgan microdispositivos de catéter con características que proveen respuesta axial efectiva, buena distribución de fuerzas de flexión y un perfil atenuado de rigidez de flexión que minimiza las variaciones bruscas de la rigidez. Un dispositivo de catéter incluye un eje interno microfabricado que tiene una pluralidad de espacios vacíos, y un miembro externo que incluye un material de polímero dispuesto entre los espacios vacíos. El dispositivo de catéter provee rigidez de flexión no lineal, de forma tal que la flexión se vuelve más difícil conforme aumenta el ángulo de flexión
