    摘要： Dilators with a threaded distal portion 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 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.

    摘要： Retractor cannula systems may be used for accessing and visualizing the spine and related methods of treatment, including a forward-looking retractor cannula system for creating a working space and the retractor cannula system having atraumatic dissection capability to allow visualization in spine. The devices and methods described may be used, for example, to perform annulus repair, herniated disc excision, and denervation of neurological tissue; to dispense pharmacological agents and/or cell or tissue therapy agents; to diagnose disc degeneration and bony degeneration, spinal stenosis, and nucleus decompression, and to perform disc augmentation.

    摘要： A disposable seal assembly for use with a reusable cannula preferably includes a flapper valve fluid seal and at least one instrument seal. The instrument seal has a sacrificial flange and a sealing flange that protrude from an inner baffle connected to the assembly's main body by a flexible outer baffle, and at least one elastomeric rib extending between the inner baffle and the body to prevent inversion of the inner baffle. Preferably, a surface of the sacrificial flange is configured to prevent the flanges from sticking together during use. An adaptor, tethered to the assembly's main body, has a central channel with an hourglass profile, a concave distal flange, distal bumpers for preventing the adaptor from translating too far into the main body, and a grip portion shaped to allow a user conveniently to separate the adaptor from the main body. Other aspects include systems with a reusable cannula, and methods for using such systems.

    摘要： Systems and methods for accessing the spine include tissue penetrating members with direct visualization capability that may be used to form an access pathway to a targeted treatment site. The direct visualization capability, which may be provided by fiberoptic illumination and imaging components, may be use to visualize the tissue as the access pathway is formed by the tissue penetrating member. The tissue penetrating members include catheters and cannulas with sharpened tips with integrated fiberoptic components and/or channels in which a fiberscope or miniscope may be inserted. Apertures and/or transparent materials are provided to permit imaging of tissue about the distal end of the tissue penetrating member.

    摘要： Systems and methods for treating disc herniation or degeneration, disc degeneration, and vertebral body fracture include surgical and endoscopic access and removal of disc tissue. The tissue removal devices that may be used include rotatable blade devices having flow control surfaces that may be inserted into a vertebral disc and rotated to pulverize the disc material and facilitate its removal.
