Abstract: Systems, apparatus, and methods are provided for promoting blood flow to a target tissue. In one variation, the invention involves creating a pattern of voids in connective tissue, or through a tissue having sparse vascularity, such as a tendon or a meniscus, in order to increase blood flow within the tissue. This also includes using a template device to assist in the creation of the pattern of voids. Also included is an electrosurgical device with a self-contained fluid supply for providing conductive fluid to the target tissue or to active electrodes of the device.

Abstract: Systems and methods are provided for applying a high frequency voltage in the presence of an electrically conductive fluid to create a relatively low-temperature plasma for ablation of tissue adjacent to, or in contact with, the plasma. In one embodiment, an electrosurgical probe or catheter is positioned adjacent the target site so that one or more active electrode(s) are brought into contact with, or close proximity to, a target tissue in the presence of electrically conductive fluid. High frequency voltage is then applied between the active electrode(s) and one or more return electrode(s) to non-thermally generate a plasma adjacent to the active electrode(s), and to volumetrically remove or ablate at least a portion of the target tissue. The high frequency voltage generates electric fields around the active electrode(s) with sufficient energy to ionize the conductive fluid adjacent to the active electrode(s).

Abstract: A wheeled support for a vegetation trimmer which includes a first body and a second body. The first body has a wheel end and a clamp end. A first wheel is positioned at the wheel end of the first body. The second body also has a wheel end and a clamp end. a second wheel is positioned at the wheel end of the second body. A pivotal assembly extends between and connects the wheel end of the first body and the wheel end of the second body. This pivotal assembly leaves a vegetation trimmer receiving space between the first body and the second body. A clamp clamps together the clamp end of the first body and the clamp end of the second body, thereby clamping a body of a vegetation trimmer in the vegetation trimmer receiving space between the first body and the second body.

Abstract: Systems and methods are provided for removing adipose or fatty tissue underlying a patient's epidermis is disclosed (e.g., liposuction, abdominoplasty, and the like). The method includes positioning one or more active electrode(s) and one or more return electrode(s) in close proximity to a target region of fatty tissue. A high frequency voltage difference is applied between the active and return electrodes, and the fatty tissue or fragments of the fatty tissue are aspirated from the target region. The high frequency voltage either softens the fatty tissue or completely removes at least a portion of the tissue. In both embodiments, the remaining fatty tissue is more readily detached from the adjacent tissue in the absence of energy, and less mechanical force is required for removal. The bipolar configuration of the present invention controls the flow of current to the immediate region around the distal end of the probe, which minimizes tissue necrosis and the conduction of current through the patient.

Abstract: A system for measuring seatbelt forces is used to control deployment of vehicle airbags. The system includes a seatbelt anchor assembly having a bracket mounted to a vehicle structure adjacent to a vehicle seat. A seatbelt mechanism has a belt portion that is looped through the bracket. The seatbelt is used to secure passengers or an infant car seat to the vehicle seat. A sensor is engaged with the anchor assembly and is used to measure the magnitude of forces exerted on the seatbelt by the passenger or car seat. The sensor generates a signal representative of the seatbelt forces, which is used to control deployment of the airbag.

Abstract: A dual fuel injection valve separately and independently injects two different fuels into a combustion chamber of an internal combustion engine. A first fuel is delivered to the injection valve at injection pressure and a second fuel is either raised to injection pressure by an intensifier provided within the injection valve, or delivered to the injection valve at injection pressure. Electronically controlled valves control hydraulic pressure in control chambers disposed within the injection valve. The pressure of the hydraulic fluid in these control chambers is employed to independently actuate a hollow outer needle that controls the injection of the first fuel. Disposed within the outer needle is an inner needle that controls the injection of the second fuel. The outer needle closes against a seat associated with the injection valve body and the inner needle closes against a seat associated with the outer needle.

Abstract: Weight sensor assemblies for measuring weight on a vehicle seat are mounted at the connecting points between a seat bottom frame and a seat mounting member. The weight sensor assemblies each include a beam member having a bendable center body portion for supporting a stain gage. The strain gage and associated traces are screen printed on the surface of the beam. The beam acts similar to a dual constrained cantilever beam, concentrating the bending at a reduced neck section that narrows in the middle of the center body portion. The strain gage measures strain resulting from bending in the center body portion caused by a weight force being applied against the seat.

Abstract: The present invention is directed to systems, methods and apparatus for removing implanted objects from a patient's body, particularly implanted endocardial or epicardial pacemaker leads and transvenous defibrillation leads from a patient's heart. In one aspect of the invention, an electrosurgical catheter is advanced to a position within the thoracic cavity adjacent a portion of a pacemaker lead that is affixed to heart tissue. Preferably, the catheter is advanced over the pacemaker lead, i.e., using the pacemaker lead as a guidewire, to facilitate this positioning step. Once the distal end of the catheter reaches a blockage, or a portion of the lead that is attached to fibrous scar tissue, a high frequency voltage difference is applied between one or more electrode terminal(s) at the distal end of the catheter and one or more return electrode(s) to remove the scar tissue around the lead.

Abstract: A hydraulically actuated dual fuel injector separately injects two fuels into a combustion chamber of an internal combustion engine. In particular, the two fuels may be controlled quantities of a first liquid fuel and a second gaseous fuel that are used to fuel a diesel engine. The injector preferably begins injecting the first fuel sequentially before beginning to inject the second fuel.

Abstract: Systems and methods are provided for treating a discolored blood vessel in tissue under the surface of the skin. In this method, one or more active electrode(s) are positioned in close proximity to a target region of the blood vessel, and a sufficient high frequency voltage is applied to the electrode terminal(s) to cause thermal damage to a target region within the blood vessel. The thermal injury causes the vessel to shrink or to thrombose and collapse so that blood flow through the vessel is restricted or completely interrupted. Preferably, the vessel is injured with minimal thermal energy being applied to the surrounding tissue, which prevents the tissue discoloration or scarring associated with prior art thermal processes. The electrode terminal(s) may be positioned on the external surface of the skin, or they may be introduced through a percutaneous penetration in the outer skin surface to the blood vessel.

Abstract: A dynamic fluid sealing system for a fuel injection valve employs sealing-fluid to separate a gaseous fuel and a second fluid in the fuel injection valve, thereby preventing leakage of the gaseous fuel into the second fluid. A pressure-balancing system, which includes a pressure-balancing device, reduces the pressure differential between the sealing-fluid and the gaseous fuel used in the injection valve. At the same time, the pressure balancing system dynamically balances the sealing-fluid pressure such that the sealing-fluid pressure is equal to or slightly greater than the pressure of the gaseous fuel within the injection valve. The pressure differential between the gaseous fuel and the sealing-fluid may be maintained throughout the operating range of engine speeds, engine loads, and fuel cut-off conditions so as to prevent leakage of compressible gaseous fuel into the second fluid.
