  • Publication number: 20140155695
    Abstract: Systems and methods for treating spinal stenosis include endoscopic access devices and bone removal devices used to perform a foraminotomy or other bone removal procedures. A bone removal device includes a cannulotome with an endoscopic imaging lumen. Optionally, an endoscope retaining device can be used to facilitate advancement of the endoscope through the cannulotome.

  • Publication number: 20130317505
    Abstract: Systems and methods for treating disc herniation include surgical and endoscopic access and removal of disc tissue. The tissue removal devices that may be used include flexible elongate members, such as a cable, that may be inserted into a vertebral disc and rotated to pulverize the disc material and facilitate its removal.

  • Patent number: 8343035
    Abstract: Dilators with a threaded distal portion and direct visualization capability may be used for penetrating and dilating stiff tissues and bones. The threaded portion of a dilator engages the tissue between the insertion site and the target site, and may be rotated for advancing through the target tissue in a more controlled fashion. The direct visualization capability may be used to visualize the ligament as the threaded distal portion passes through the ligamentum flavum. The devices and methods described may be used in procedures, for example, where ligaments surrounding the epidural space need to be dilated in order to deliver one or more surgical instruments into the epidural space.

  • Publication number: 20110288553
    Abstract: Systems and methods for treating spinal stenosis include endoscopic access devices and bone removal devices used to perform a foraminotomy or other bone removal procedures. Some of the bone removal devices include expandable members which may be used to control the forced exerted and/or position of the bone removal mechanism, and to protect neurovascular structures and other soft tissue structures from the bone removal mechanism. Other bone removal devices include a trephine with a viewing window and a guide wire lumen used to position the trephine at a target tissue site using an anchored wire. The viewing window may be used to monitor structures or tissues adjacent to the target tissue site.

  • Publication number: 20110098711
    Abstract: Disclosed herein are tissue-removal devices and methods for treating spinal diseases using such devices. The tissue-removal devices may comprise a cable and/or extendable elements with a retracted and a deployed configuration. The cable and/or extendable elements may be distally supported and restrained by a support element such that the support element may be pushed transversely away when the extendable element is distally extended into its deployed configuration. An annular cutting element may be provided about the distal end of the extendable element or the support element. Various configurations of the extendable and support elements are described herein, as well as methods of using tissue-removal devices with extendable and support elements coupled by an annular cutting element for treating spinal diseases.

  • Publication number: 20110087257
    Abstract: Systems and methods for minimally invasive discectomy procedures are described herein. The systems include a bendable flexible cannula may have a straight configuration suitable for insertion and withdrawal into spinal tissue, and a curved configuration suitable for accessing certain areas of a vertebral disc that may be difficult to reach in the straight configuration. A cannula is straightened by inserting a straight stylet therethrough. The straight stylet may have a deflectable region that facilitates its insertion into the cannula. Removal of a straight stylet from a cannula may allow the cannula to assume its curved configuration. The systems may be used with tissue removal devices, and certain variations of tissue removal devices may comprise a collector for aspiration, as well as a travel limiter to restrict inadvertent motions of the tissue removal devices within a vertebral structure.
