Abstract: A treatment apparatus which applies a magnetic field of a proper magnitude to a specific place of a treatment object includes a magnetic field generation part provided with first and second core members having end faces arranged oppositely and radiating lines of magnetic force therebetween and coils at the bases of the first and second core members. Additionally, a space adjustment part adjusts a space between the end faces of the first core member and that of the second core member, and a control part controls energization of the coil according to the space between the end face of the first core member and that of the second core member, thereby adjusting the intensity of the magnetic field to be generated by the magnetic field generation part.

Abstract: A light irradiating device capable of irradiating with a low output energy a lesion or a skin deep portion with light having a high-vasodilating-effect wavelength. Light including a wavelength having a vasodilating effect is emitted from the output portion at the tip end of a probe. The output density of the light is preferably 100 to 1550 mW/mm2. The wavelength of light having a vasodilating effect is preferably 450 to 650 nm. A skin contact surface is preferably formed at the tip end of the probe, and the output portion is preferably disposed at the skin contact surface.

Abstract: A catheter for percutaneous insertion includes a sheath portion, an insertion member, an injection needle, and paired electrodes. The sheath portion has a lumen extending therein. The insertion member is disposed slidably in the lumen of the sheath portion and provided with a distal end portion capable of protruding from a distal end portion of the sheath portion. The injection needle is disposed in the distal end portion of the insertion member for injecting a therapeutic composition to a target tissue. The paired electrodes are disposed in a distal end portion of the catheter for measuring impedance.
