A forceps that includes a housing, a cutting assembly, and an actuator. The housing has a shaft attached thereto that extends therefrom and is configured to support a pair of jaw members at a distal end thereof. The jaw members are movable to grasp tissue therebetween. The cutting assembly includes a spring element that has proximal and distal ends. The proximal end of the spring element is fixed to a boss disposed within the housing and the distal end of the spring element includes a cutting edge. The spring element is coiled at a proximal end thereof to create a spring bias against the boss. The actuator is operably coupled to the spring element and is configured to selectively advance the cutting edge of the spring element into the jaw members against the spring bias to sever tissue disposed therebetween.

A portable wound treatment apparatus, for stimulating the healing of superficial wounds, comprises a housing containing a suction pump and a canister for containing fluids drawn from the wound. The housing is supported on a harness or belt worn by the patient. The canister is connected to a porous wound dressing at the wound site via a plurality of tubes, a multi-lumen tube or a combination thereof. A rechargeable battery pack may be incorporated within the housing or externally thereto. The external battery pack may be shaped to balance the housing on the harness or belt. Pressure transducers are provided to monitor and report pressures at the wound site or internal to the canister. Monitored pressures may also be utilized to determine the filled state of the canister and, thereafter, either report this state to the operator or automatically discontinue suction from the wound, or both.

A vehicular "black box" provides recording means by which driver action can be reviewed after an accident or collision, as well as indicating immediate vehicle disposition status to the driver. Using cameras (which may be very small), the disposition of the vehicle in its lane is determined by detecting the highway lines painted on the road. The data is also recorded so that should an accident or collision occur, the events leading up to such an event are made available for later review and analysis.

A growing prosthesis comprising a joint replacement part, a prosthesis stem, a stem-anchoring element, and an element with corresponding drive provided for the lengthening of the growing prosthesis. The element provided for the lengthening of the growing prosthesis is a spindle element arranged in the stem-anchoring element.

With a sanding-disc receiving element for a hand-guided electric sanding tool, an eccentric sander (15) in particular, the sanding-disc receiving element including a bearing flange (2) with a plurality of driving lugs (3) protruding in the axial direction around the surface (18), and a plurality of screw holes (8), and including a bearing (1) fixed in the axial and radial direction on the bearing flange (2), simple, reliable installation of the sanding disc (5) on the bearing flange (2) is ensured by the fact that the driving lugs (3) and the screw holes (8) are arranged equidistantly relative to each other on a common circle around the central axis of the bearing flange (2).

In a resistance value variable memory, substrate voltages and / or substrate biases of a digit line drive circuit, a word line drive circuit and a bit line drive circuit for a memory cell array are changed in accordance with an operation mode. A driving power on signal lines connected to memory cells can be increased, and a leakage current during standby can be reduced without increasing a circuit layout area.

The present inventions relate to devices and methods that improve the positioning and fit of orthopedic reconstructive joint replacement stem implants relative to existing methods. For example, an embodiment of the device provides a stem component comprising proximal and distal body portions that can be configured to mimic a geometric shape of a central cavity region created in a bone of a joint for improving conformance and fixation of the stem component thereto. Further, another embodiment provides a system of stem implants that each have a unique medial offset for facilitating the matching of an implant to the geometry of a central cavity region of a bone. Additionally, an inclination angle of a resection surface of each of the implants in the system can remain constant or vary as a function of the medial offset.

A fluid flow actuated downhole tool is configurable in at least a first tool configuration and a second tool configuration. The tool comprises a tubular housing and an activating sleeve, the housing being adapted to catch the sleeve when the sleeve is dropped from surface and the engagement of the sleeve with the housing permitting actuation of the tool between the first and second tool configurations. A flow restriction is provided for permitting fluid flow actuation of the tool when the activating sleeve has been caught in the body.

A method of producing an improved polyethylene, especially an ultra-high molecular weight polyethylene utilizes a sequential irradiation and annealing process to form a highly cross-linked polyethylene material. The use of sequential irradiation followed by sequential annealing after each irradiation allows each dose of irradiation in the series of doses to be relatively low while achieving a total dose which is sufficiently high to cross-link the material. The process may either be applied to a preformed material such as a rod or bar or sheet made from polyethylene resin or may be applied to a finished polyethylene part. If applied to a finished polyethylene part, the irradiation and annealing must be accomplished with the polyethylene material not in contact with oxygen at a concentration greater than 1% oxygen volume by volume. When applied to a preform, such as a rod, the annealing of the bulk polymer part of the rod from which the finished part is made must take place on the rod before the implant is machined therefrom and exposed to oxygen.
