Abstract: The present disclosure relates to a balloon catheter including an external catheter; a balloon connected to one end of the external catheter, inflatable and deflatable, and configured to be inserted into or expelled from a target site of a living body; and an internal catheter movable along the external catheter in a first direction for insertion into the balloon or a second direction for expelling the balloon, wherein the internal catheter is expelled from the balloon while the balloon is inflated and fixed to the target site of the living body.

Abstract: Disclosed is a radiation and magnetic field generating apparatus irradiating photon beam radiation to in-body affected tissue of a subject including a radiation generating unit that irradiates the photon beam radiation to the subject and induces generation of secondary electrons in an area of the subject where the photon beam radiation is irradiated, a magnetic field generating unit, which is provided to be inserted into a body, which includes an insertion structure for forming a low-density space, and which forms a magnetic field in an area in which the secondary electrons are generated, and a synchronization control unit that controls formation of the magnetic field such that a part of the secondary electrons moves to the low-density space based on a relationship between an area where the photon beam radiation is irradiated and a location of an affected part, and controls the formation of the magnetic field.

Abstract: The present disclosure relates to an electron beam output device for medical use. The electron beam output device includes at least: an electron beam generator that generates an electron beam having a pencil beam shape; an electron beam accelerator that receives the electron beam generated by the electron beam generator and accelerates the received electron beam; a catheter, through which the electron beam received from the electron beam accelerator passes, the catheter is placed to be directed toward a target site, or is configured to enter an inner passage of the target site; and a first magnetic field generator that is provided in the catheter and generates a magnetic field that refracts the electron beam that is outputted from the catheter.
