Devices, systems, and method for treating urinary incontinence generally rely on energy delivered to a patient's own pelvic support tissue to selectively contract or shrink at least a portion of that pelvic support tissue so as to reposition the bladder. The energy will preferably be applied to the endopelvic fascia and / or an arcus tendineus fascia pelvis. The invention provides a variety of devices and methods for applying gentle resistive heating of these and other tissues to cause them to contract without imposing significant injury on the surrounding tissue structures. Alternatively, heat-applying probes are configured to heat tissue structures which comprise or support a patient's urethra. By applying sufficient energy over a predetermined time, the tissue can be raised to a temperature which results in contraction without significant necrosis or other tissue damage. By selectively contracting the support tissues, the bladder neck, sphincter, and other components of the urinary tract responsible for the control of urinary flow can be reconfigured or supported in a manner which reduces urinary leakage.

The method includes inserting an introducer needle through the annulus fibrosus by puncturing the annulus fibrosus with the introducer needle, injecting an in situ curable, bio-compatible polymerizable or polymeric material composition into the disc through the introducer needle directly or indirectly so that the in situ curable composition contacts a defect in the annulus fibrosus; and curing said material in situ.

A minimally invasive orthopedic bone attachment system comprising a pedicle screw and guide support sleeve for insertion of the screw. The pedicle screw is a self-boring, self-tapping integral screw having a distal sharply pointed end for guiding the insertion of the screw as well as forming a borehole for the self-tapping threads of the screw. The proximal end of the screw provides a cylindrical extension which can include a recess for receiving a rotational drive tool or wrench. The length of the threads and the type of threads provided in the screw are designed for the type of orthopedic surgery that is intended. A relatively thin hollow support sleeve including an internal threaded section in the distal end is provided to match the threads and the length of the threaded portion of the pedicle screw. The proximal end of the sleeve includes a central passageway having an internal diameter that can receive the extension portion of the screw and also guide and receive a drive device for the screw. A retainer clip associated with circumferential slots spacedly indexed along the longitudinal surface of the drive device can be used to limit the depth of the screw upon insertion as well as to lock the drive device as an assembly with the screw and sleeve to form the attachment system. A small diameter passageway can be provided along the longitudinal axis of the assembly extending from the proximal end of the drive device through the screw to exit through the pointed distal end of the screw. A thin rigid rod having a point at the distal end is slidably positioned within the narrow passageway. The proximal end of the road includes a cap. A flange surface on the under portion of the cap limits the travel of the rod through the assembly. The length of the rod is determined so that it equals the length of the assembly plus an additional dimension corresponding to the anticipated installed depth of the screw. Prior to insertion of the screw, the rod is driven into the bone through the assembly. The location of the rod is ascertained by an image guidance system to determine the correct final projected location of the screw upon installation.

Disclosed are a means and method for rapidly and accurately positioning a toroidal balloon with its distal surface placed tightly against the endocardial surface of the left atrium at a location that is close to the ostium of a pulmonary vein.

The toroidal balloon is wrapped circumferentially around a tapered balloon that is placed into the pulmonary vein. This system can be applied successively to at least one or as many as all four of the pulmonary veins that enter the left atrium to treat the patient's atrial fibrillation.

If an impact occurs with an impact energy which exceeds an elastic limit of a bumper while a shock-absorbing member is in a projected position, a bumper stay is forced to move rearward along a first actuating chamber to cause the shock-absorbing member to pivot to a received position. The impact energy is primarily absorbed by an elastic force of a first spring which biases the shock-absorbing member toward the projected position. When the impact energy is not thoroughly absorbed by the first spring, the shock-absorbing member fully pivots into its received position by the bumper stay which is continuously moved rearward. At this time, a second spring which biases the shock-absorbing member forward and is prevented from being stretched forward by the shock-absorbing member, is contacted with the bumper stay via a support plate. Accordingly, the second spring secondarily absorbs the impact energy while being more compressed by the bumper stay which continuously moves rearward after causing the shock-absorbing member to fully pivot to its received position.
