  • Patent number: 10849733
    Abstract: The present invention relates to a glucose-reactive artificial muscle, and more particularly, to a carbon nanotube, a hydrogel-based glucose-reactive artificial muscle which has a reversible volume change due to variations in glucose concentration, a method of forming the same, a rotary artificial muscle using the same, and a method of detecting glucose. The glucose-reactive artificial muscle according to the present invention may sense variations in glucose concentration with high sensitivity within a short time by providing reversible twisting using the swelling and shrinkage of hydrogels, which occur due to a change in internal anionic charges, caused by the bonding between a boronic acid introduced to the hydrogels and glucose.

  • Patent number: 10842613
    Abstract: Devices and methods of treatment useful in implantation and post-implantation procedures are described. The devices and methods may be used to correct deformities and/or asymmetries in tissues near an implant, support tissues near an implant, and/or refine the shape of an area of the body after placement of an implant, for example. The method may include inserting a cannula into tissue adjacent to or near an implant of a patient, and delivering fat or other filler material(s) to the tissue, wherein the cannula is configured to prevent or otherwise minimize the risk of damaging the implant, e.g., a breast implant. The cannula may include an elongate member having a lumen therein, an atraumatic distal tip, and an opening disposed proximal to the distal tip, the opening being in fluid communication with the lumen for delivering the fat or other filler material(s).
