  • Patent number: 12005269
    Abstract: The provided is a handpiece for skin laser treatment and a medical laser treatment apparatus including the same. The disclosed handpiece for skin laser treatment may include a handpiece body including a laser irradiation portion for irradiating a laser beam to a treatment target area of the skin of a person to be treated and a refrigerant spraying portion for spraying a refrigerant in the treatment target area; and an end tool member provided at an end of the handpiece body and configured to maintain a distance between the laser irradiation portion and the skin in contact with the skin of the person to be treated and to at least partially limit a target area corresponding to the treatment target area.

  • Patent number: 10380396
    Abstract: An electronic device is provided, and may comprise a housing, a touch screen module, and a processor. The housing may include a first surface facing a first direction, a second surface facing a second direction opposite the first direction, and a side member including a side surface surrounding at least a part of a space between the first surface and the second surface. The touch screen module may be exposed through at least a part of the first surface. The processor may be located in the housing and electrically coupled to the touch screen module. In the electronic device, at least a part of the first surface may be a display area, and at least a part of the display area may be a fingerprint sensing area.

  • Patent number: 6714806
    Abstract: An improved system for monitoring the status of an IMD such as a medical electrical lead during an implant procedure is provided. The system includes a signal generator for supplying a first signal such as a constant current or voltage to the IMD. A resulting voltage or current signal is generated, respectively, and may be sensed as an indication of the impedance of a portion of the body that is proximal to one or more electrodes carried by the lead. This impedance indication is converted to an audible signal having a frequency that is proportional to the amplitude of the impedance indication. The pitch of the audible signal therefore rises when measured impedance increases, and drops as the impedance decreases. These pitch changes allow a user to determine positional information associated with the IMD, including the degree of lead tissue contact and extent of fixation of a device to tissue.
