摘要：
A device (500) for treating the prostate, comprising: an introducer rod (510, 512) sized and configured for transurethral access in a patient； a steam generator (570) configured to generate a condensable steam； and a steam supply needle (540) in communication with the steam generator, and slidably disposed within the introducer rod, characterized in that the device further comprises: a magnetic actuator (600A, 600B, 602A, 602B, 610, 612 ) configured to apply magnetic force to the steam supply needle, to move the steam supply needle between a retracted position, within the introducer rod, and an extended position, at least partially outside the introducer rod, the magnetic actuator comprising, a first magnet (612), carried by the steam supply needle, a second magnet (602A), carried on a mount (600A) of a handle (504) of the device, and a third magnet (602B), carried on a second mount (600B) of the handle, in which the second magnet is configured to interact with the first magnet, and the third magnet is configured to interact with the first and second magnets, to move the first magnet and the steam supply needle proximally and distally along the longitudinal axis of the introducer rod.Un dispositivo (500) de tratamiento de la próstata, que comprende: un vástago introductor (510, 512) dimensionado y configurado para el acceso por vía transuretral en un paciente； un generador de vapor (570) configurado para generar un vapor condensable； y una aguja (540) de suministro de vapor en comunicación con el generador de vapor, y dispuesta de manera deslizante dentro del vástago introductor, caracterizado porque el dispositivo comprende además: un accionador magnético (600A, 600B, 602A, 602B, 610, 612) configurado para aplicar fuerza magnética a la aguja de suministro de vapor, para mover la aguja de suministro de vapor entre una posición retraída, dentro del vástago introductor, y una posición extendida, al menos parcialmente por fuera del vástago introductor, comprendiendo el
