Abstract: A pulse application method includes: setting a wavelength of light within a range in which a temperature rise width of collagen fibers in living tissue when the light is applied to the living tissue is larger than a temperature rise width of water containing cells that are contained in the living tissue and that are present around the collagen fibers; and applying a pulse of light with the set wavelength to the living tissue to heat the living tissue.

Abstract: A medical device includes an extracorporeal unit including a power transmitting unit that transmits electric power from outside of a living body into the living body in a non-contact manner, and a medical instrument embedded in the living body. The medical instrument includes a power receiving unit that receives the electric power transmitted from the power transmitting unit, a soft portion through which an injection needle is inserted, and a plurality of light emitting units that are provided along an outer edge of the soft portion and are each configured to emit light using the electric power received by the power receiving unit. A light amount adjusting unit that adjusts a light amount of a light-irradiated region including one or more light-irradiated portions to be projected on a body surface from the plurality of light emitting units.

Abstract: A medical device that can confirm a predetermined portion in a medical instrument implanted for use in a body. A medical instrument includes a main body part, and a medicinal solution container installed in the main body part. A notification part includes a plurality of light emitting portions that emit light by use of power received by a power receiving part to notify that a predetermined state is reached, when a relative positional relation between a power transmission part and the power receiving part reaches the predetermined state by moving the power transmission part, and a soft part into which an injection needle is inserted, the plurality of light emitting portions are arranged along an outer edge of the soft part. A first coil is a coreless coil disposed to have an inner diameter larger than an outer diameter of the medicinal solution container.
