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.

Abstract: 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.

Abstract: Apparatus and methods are provided for treating female urinary incontinence by applying a form of energy to tissue in the vicinity of the urethra and/or bladder outlet to change tissue compliance without substantially narrowing the urethral and/or bladder outlet lumen. The apparatus comprises an elongated shaft having a means for treating urethral tissue and an expandable member deployable distal of the means for treating. The expandable member is configured to be anchored against the bladder outlet to dispose the means for treating at a desired treatment site in the urethra using only tactile feedback. The means for treating may include a needleless RF electrode, an ultrasound transducer, or a cryogenic probe configured to be advanced through a hollow needle, each of which are designed to reduce or eliminate symptoms associated with urinary incontinence.

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.
