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: 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.

Abstract: 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.
