  • Patent number: 11642536
    Abstract: Embodiments described herein relate to implantable medical devices (IMDs) and methods for use therewith. Such a method includes using an accelerometer of an IMD (e.g., a leadless pacemaker) to produce one or more accelerometer outputs indicative of the orientation of the IMD. The method can also include controlling communication pulse parameter(s) of one or more communication pulses (produced by pulse generator(s)) based on accelerator output(s) indicative of the orientation of the IMD. The communication pulse parameter(s) that is/are controlled can be, e.g., communication pulse amplitude, communication pulse width, communication pulse timing, and/or communication pulse morphology. Such embodiments can be used to improve conductive communications between IMDs whose orientation relative to one another may change over time, e.g., due to changes in posture and/or due to cardiac motion over a cardiac cycle.

  • Patent number: 11642168
    Abstract: A pulsed laser skin treatment device is for laser induced optical breakdown of hair or skin tissue. The device has a light exit window to be placed against a surface to be treated such as skin during use. A feedback system is used for determining a state of contact between the light exit window and the surface. To this end the feedback system is capable of detecting a feedback signal representative for the state of contact. If the feedback signal or the state of contact is such that the risk of skin surface or device damage by the device operation is too high, the user or the device has a way to interrupt the treatment or to reduce light output to reduce or eliminate this risk.

  • Patent number: 11602631
    Abstract: A method and apparatus to treat hyperhidrosis is provided in which a battery provides a milliampere electrical current to the inside of a waterproof glove containing water and sealed to the user's arm so that circulation is not unduly restricted while the user can raise the water-filled gloves and hands above the user's head without leaking. A tapered portion on the proximal end of each glove is folded inside the glove to seal against the user's arm to form a pocket between the tapered portion which seals against the user's arms, and part of a wrist portion of the glove located radially outward of the tapered portion. When the user's gloves and hands rotate upward, water collects in the pocket(s) while the tapered portion provides a leakproof seal, thus allowing manual manipulation while wearing the water-filled gloves.
