Abstract

Se escribe un procedimiento para formar una punta de catéter, en el cual se forma un molde que tiene una superficie interna, complementaria de la superficie externa deseada de la punta de catéter, de modo que tenga dos zonas de temperatura; una primera zona de mayor temperatura está situada proxima a la punta distal del catéter, y una zona de menos temperatura está situada distal con respecto a la zona de mayor temperatura; se coloca un catéter, al que se le va a formar la punta, en un mandril o aguja y se calienta el molde; cuando el catéter y el mandril son insertados en el molde, el material de catéter se ablanda y comienza a fluir dentro del molde; la porcion de mayor temperatura suministra el calor necesario para ablandar el material de catéter y fluye a la zona de menor temperatura, en donde la menor temperatura hace que el material de catéter se vuelva más viscoso o resolidifique; cuando se vuelve más viscoso el material de catéter, en la propia punta, actua como una retencion para prevenir el flujo adicional del material, eliminando así la pérdida desde el extremo del molde.
