  • Publication number: 20230149048
    Abstract: A system for non-invasively adjusting the curvature of a spine includes a housing having a first end and a second end, a first rod having a first end telescopically disposed within a cavity of the housing along a first longitudinal axis at the first end of the housing and having a first threaded portion extending thereon, and a second end configured to be coupled to a first portion of a spinal system of a subject, a second rod having a first end telescopically disposed within the cavity along a second longitudinal axis at the second end of the housing and having a second threaded portion extending thereon, and a second end configured to be coupled to a second portion of the spinal system of the subject, a driving member rotatably disposed within the cavity and configured to be activated from a location external to the body of the subject.

  • Publication number: 20180028130
    Abstract: A method for positioning a treatment instrument in a subject involves positioning a tissue protector of a visualization instrument in an epidural space of the subject. The tissue protector is viewed and positioned in the epidural space using fluoroscopy. A treatment instrument between a first vertebra and a second vertebra and while viewing the tissue protector positioned in the epidural space. A decompression procedure is performed using the treatment instrument.

  • Publication number: 20130289399
    Abstract: A method for treating spinal nerve compression includes positioning a media delivery device between a first vertebra and a second vertebra. A visualization media can be delivered from an outlet of the media delivery device while the outlet to the media delivery device is positioned outside of an epidural sac of the subject. The media delivery device can be spaced apart from a portion of the epidural sac between a spinal cord and a ligamentum flavum. A series of instruments can be used to perform a decompression procedure on the subject.
