  • Publication number: 20230086561
    Abstract: An implantable guide element comprises a main body formed from a biocompatible material. One or more grooved surface structures are provided on and/or within the main body, each grooved surface structure comprising one or more grooves for directionally guided growth of fibro-axonal tissue. At least one of the one or more grooved surface structures may form a channel along or within the main body, within which an electrode is disposed in spaced relationship from a wall of the channel along at least part of its length.

  • Patent number: 10964232
    Abstract: Systems and methods of microsuture training include receiving an image or video of a suture; extracting features of the suture from the image or video; scoring the suture based on the extracted features of the suture and based on a rating and complexity of the suture to determine a quality of the suture in an objective manner. A suture training system includes a suture training apparatus configurable with a plurality of orientations of simulated or actual tissue to simulate natural anatomical orientations encountered in actual surgery, wherein the plurality of simulated tissue orientations are objective based on fiducial markings on the suture training apparatus; and an image analysis system configured to receive an image or video of a suture performed on the suture training apparatus; extract features of the suture from the image or video; score the suture.
