Abstract: An apparatus and method are provided for control contraction of tissue that includes collagen fibers. The apparatus includes a handpiece, and an electrode with an electrode proximal end associated with the handpiece. A distal end of the electrode has a geometry that delivers a controlled amount of energy to the tissue for a desired contraction of the collagen fibers. This is achieved while dissociation and breakdown of the collagen fibers is minimized. The handpiece, with electrode, is adapted to be introduced through an operating cannula in percutaneous applications. Additionally, an operating cannula may be included in the apparatus and be attached to the handpiece. The apparatus and method provides for a desired level of contraction of collagen soft tissue without dissociation or breakdown of collagen fibers.

Abstract: An article sortation system includes a plurality of transport units which are movable along a conveying path between induction stations and discharge stations along each side of the conveying path. Each transport unit has side by side loading and support capability and is operable to receive packages from induction stations and discharge the packages at an appropriate discharge station. The system includes a control which determines the destination of articles and resolves blocking conditions between articles at the induction stations or at the transport units. The system may include a reinduction station for receiving an article from a transport unit and reinducting the article onto a transport unit, in order to resolve a blocking condition between a pair of articles on the respective transport unit.

Abstract: A medical probe device comprises a catheter having a stylet guide housing with one or more stylet ports in a side wall thereof and a stylet guide for directing a flexible stylet outward through the stylet port and through intervening tissue at a preselected, adjustable angle to a target tissue. The total catheter assembly includes a stylet guide lumen communicating with the stylet port and a stylet positioned in said stylet guide lumen for longitudinal movement from the port through intervening tissue to a target tissue. The stylet can be an electrical conductor enclosed within a non-conductive layer, the electrical conductor being a radiofrequency electrode. Preferably, the non-conductive layer is a sleeve which is axially moveable on the electrical conductor to expose a selected portion of the electrical conductor surface in the target tissue. The stylet can also be a microwave antenna. The stylet can also be a hollow tube for delivering treatment fluid to the target tissue. It can also include a fiber optic cable for laser treatment. The catheter can include one or more inflatable balloons located adjacent to the stylet port for anchoring the catheter or dilation. Ultrasound transponders and temperature sensors can be attached to the probe end and/or stylet. The stylet guide can define a stylet path from an axial orientation in the catheter through a curved portion to a lateral orientation at the stylet port.

Abstract: A method for treating a sphincter provides a polymer material having a liquid state. The method also provides a catheter having a distal end, a tissue piercing device carried by the distal end, and an energy delivery device coupled to the tissue piercing device. The tissue piercing device has a lumen. The method introduces the catheter into an esophagus and pierces an exterior sphincter tissue surface within with the tissue piercing device. The method advances the tissue piercing device into an interior sphincter tissue site and conveys the polymer material while in a liquid state through the lumen into the interior sphincter tissue site. The method delivers energy to the tissue piercing device to transform the polymer material into a less liquid state within the interior sphincter tissue site, to thereby remodel the sphincter.

Abstract: Methods treat a tissue region. In one arrangement, the methods deploy an electrode on a support structure in a tissue region at or near the cardia of the stomach. In one embodiment, the support structure has a proximal region and a distal region. The proximal region is enlarged in comparison to the distal region, and the electrode is carried by the enlarged proximal surface. The methods advance the electrode in a path to penetrate the tissue region and couple the electrode to a source of radio frequency energy to ohmically heat tissue and create a lesion in the tissue region.

Abstract: Systems and methods deploy an electrode structure in contact with the tissue region. The electrode structure carries a sensor at a known location on the electrode structure to monitor an operating condition. The systems and methods provide an interface, which generate an idealized image of the electrode structure and an indicator image to represent the monitored operating condition in a spatial position on the idealized image corresponding to the location of the sensor on the electrode structure. The interface displays a view image comprising the idealized image and indicator image. The systems and methods cause the electrode structure to apply energy to heat the tissue region while the view image is displayed on the display screen.

Abstract: The invention provides a system and method for achieving the cosmetically beneficial effects of shrinking collagen tissue in the dermis in an effective, non-invasive manner, which leaves the outer layer of skin intact and undamaged. One embodiment of the invention provides electromagnetic energy to the skin of a patient. The device includes a carrier and an array of electrodes on the carrier. A microporous pad on the carrier overlies the array of electrodes, forming an interior chamber to contain an electrically conductive material. The microporous pad is adapted to contact a patient's skin and ionically transport the applied electromagnetic energy to ohmically heat dermal tissue beneath the epidermal skin region. The shape of the carrier may differ to match different skin topographies and the electrodes may be sized to extend into tissue to heat a dermal skin region.
