  • Patent number: 11786581
    Abstract: The invention is directed to methods of inducing cell recruitment and tissue regeneration at a target site in a subject. It is also based, in part, on the discovery that a subject's own biologic resources and environmental conditions can be used for in situ tissue regeneration and thereby reduce or eliminate the need for donor cell procurement and ex vivo manipulation of such donor cells. Methods are disclosed for recruitment of a subject's own stem cells to a target region by inducing a sustained positive pressure at a target site, such as the kidney, thereby increasing the number of pluripotent cells capable of differentiating to regenerate the target tissue.

  • Patent number: 11571029
    Abstract: Provided is a wrist guard designed to press the radial and ulnar parts of a wrist toward the center of the wrist by means of a compression pad, so as to prevent side effects, such as hand numbness and swelling and effectively provide a fixing force of the wrist, thereby preventing the wrist from being excessively bent and alleviating wrist pain. The wrist guard allows a user to adjust the pressure load on the radial and ulnar parts of the wrist. It is possible to smoothly insert and assemble the pressing member into a coupling body, therefore improving operational feeling, the wrist guard may be stably used, and damage due to interference can be prevented. A stable pulling operation prevents wear and damage. As an excessive pressure load on the radial and ulnar regions is attenuated, the wrist guard is more convenient and comfortable.
