    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 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.

    摘要： An apparatus and method for removing tissue and/or other material from a patient includes a shaft and a tissue disrupting mechanism operatively coupled to the shaft. The shaft may be coupled to a handpiece or a robotic or remote-controlled system. The mechanism may comprise a rotatable or other movable element having a distal portion with fixed or adjustable radial dimensions. The mechanism may have one or more tissue cutting, chopping, grinding, emulsifying or disrupting features with an adjustable outer diameter for removing substantial tissues. The apparatus may be configured to urge or draw substantial material into the device upon rotation or other movement of the shaft and/or tissue, and may optionally be coupled to sources of suction or aspiration. A radiofrequency or other energy source is optionally included for tissue ablation or other tissue remodeling effects, and/or to enhance coagulation.
