Abstract: A cautery device for biological tissue, includes: a probe including a head unit that is configured to be inserted into a living body to emit light to cauterize the biological tissue, the head unit including a first fixing member, a second fixing member, and an exit hole, the exit hole being located between the first fixing member and the second fixing member, the exit hole allowing the light to be emitted therethrough; and an elongated catheter configured to sandwich the biological tissue between the probe and the catheter, to thereby support the biological tissue, the catheter including a third fixing member configured to fix the first fixing member and a fourth fixing member configured to fix the second fixing member.

Abstract: To provide such a medical tube that a position of a distal end part thereof is easily detectable from an outside of a body of a patient, regardless of orientation of the distal end part inserted into the body. A medical tube including: a main body part having a tubular shape; at least one opening formed in a side face of a main body part; and a light transmitting part formed at one end of the main body part, the light transmitting part having a hemispherical face shape, the light transmitting part being configured to emit light from a light source.

Abstract: A medical tube position confirmation system for confirming the position of a medical tube that is used to supply nutrients to the interior of a body by means of tube feeding while an end portion thereof is inserted into (placed in) the stomach includes a light guide that is configured to guide light entering through an incident end portion so that the light exits through an exit end portion, and is configured to be insertable into the medical tube so that the exit end portion is disposed in the interior of the stomach, a light source that is optically connected to the incident end portion of the light guide and emits light containing wavelengths that pass through a living body, and a control unit that controls intensity of light emitted by the light source, wherein the control unit controls the intensity of light emitted by the light source within an intensity range that equals or exceeds a first intensity specific to a patient and is lower than a second intensity specific to the patient.

Abstract: An intraocular lighting device that is inserted into an eye in order to illuminate the inside of the eye includes a fiber-shaped light-guiding unit for guiding light emitted from a light source to an emission end, and a scattering unit that is optically connected to the light-guiding unit at the emission end and contains a predetermined scattering medium for scattering the light emitted from the light-guiding unit, a dimension of the scattering unit in a parallel direction to an optical axis direction being set to be longer than a dimension in a perpendicular direction to the optical axis direction, and the predetermined scattering medium scattering light to a larger degree as the wavelength of the light shortens.

Abstract: To provide a control apparatus for treating myocardial infarction that can suitably perform treatment of myocardial infarction, and a control method for treating myocardial infarction.

Abstract: An illumination system for illuminating a lumen within a body of a patient comprising a tube having a proximal end and an opposed distal end and an internal chamber, the tube being configured for placement within a lumen of the body. The system also includes an illumination subsystem including an optical fiber that is sized and configured to seat within the internal chamber of the tube and a light source for generating light that is emitted by the fiber optic cable. The optical fiber, when mounted within the tube and when the light source generates light, emits light at the distal end of the tube so as to transilluminate the lumen and surrounding tissue so as to be able to locate the distal end of the tube within the lumen of the patient.
