Patent CA-2429246-A1 (CA)
Title: Implantable joint prosthesis
Inventor: KUNZLER ALEX
IPC: A61F2/44
Filed: 2001-08-07
Abstract: The invention relates to a surgical implant that provides an artificial diarthroidal-like joint, suitable for use in replacing any joint, but particularly suitable for use as an intervertebral disc endoprosthesis. The invention contains two rigid opposing shells, each having an outer surface adapted to engage the surfaces of the bones of a joint in such a way that the shells are immobilized by friction between their outer surfaces and the surfaces of the bone. These outer surfaces are sufficiently rough that large frictional forces strongly resist any slippage between the outer surface and the bone surfaces in the joint. They may be convex, and when inserted into a milled concavity, are immediately mechanically stable. Desirably, the outer surfaces of the shells are adapted to allow for bony ingrowth, which further stabilizes the shells in place. The inner surfaces of the shells are relatively smooth, and adapted to slide easily across a portion of the outer surface of a central body disposed between the shells. The central body has a shape that cooperates with the shape of the inner surface of the shell so as to provide a range of motion similar to that provided by a healthy joint. A  flexible sheath extends between edges of the opposing shells. The inner surface of this sheath, together with the inner surfaces of the rigid shells, defines a cavity encasing the central body. At least a portion of this cavity is filled with a fluid lubricant, further decreasing the frictional force between inner surfaces of the shell and the surface of the central body.

Title: Method and apparatus for controlling a welding system
Inventor: HUISMANN GERD
IPC: B23K9/09
Filed: 2003-07-23
Abstract: A method and apparatus for controlling a welding-type power supply includes providing a current wave form having an arc current portion and a short circuit current portion. An arc state is entered by retracting a welding wire, and a short circuit state is entered by advancing the wire. The current enters the arc current portion prior to the creation of the arc and the current enters the short circuit current portion prior to the creation of the short, by coordinating the wave form with the wire retraction. This may be preformed on a wire having a diameter of 2.4 mm or more to a weld and applying a welding current of less than 100 amps, or of less than 35 amps. One current waveform during the arc state includes at least three segments, and the last segment is entered into prior to the short circuit state being entered, and is the same current magnitude as the current magnitude at the start of the short circuit state. Penetration and/or bead formation may be controlled by controlling the advancement of the wire into the weld pool. The balance may be user set.

Title: Electrosurgical generator
Inventor: EGGERS ANDREW R
IPC: A61B18/14
Filed: 2002-08-21
Abstract: An electrosurgical generator which provides a constant voltage and variable power output particularly suited for cutting arc formation at an active electrode which exhibits a dynamic active surface area of varying geometry. Essentially constant voltage-based control is achieved through the utilization of a d.c. link voltage the level of which functions to establish the amplitude of the output of an RF resonant inverter. A dual loop feedback control is described wherein output voltage based control signals are slowly introduced at low gain, while link voltage motor-based controls are comparatively rapidly applied. Enhanced development of a controlling d.c. link voltage is achieved through the utilization of an input network incorporating a power factor correction stage.

Title: An embolic protection device
Inventor: GILSON PAUL
IPC: A61F2/06
Filed: 1998-11-09
Abstract: An embolic protection device has a collapsible filter element (105) mounted on a carrier such as a guidewire (101). The filter element (105) collapses into the outer end of a catheter (118) for deployment and retrieval through a vascular system of a patient. The filter element (105) has a collapsible filter body with a proximal inlet end and a distal outlet end. The proximal inlet end has inlet openings sized to allow blood and embolic material enter the filter body. The outlet end has outlet openings which allow through a passage of blood but retain embolic material with the filter body. After use, the catheter (118) is movable along the guidewire (101) to engage the proximal end of the filter element and close the inlet openings before sliding over the filter element from the proximal end to the distal end to progressively collapse the filter body on the guidewire (101) for retrieval. The filter element (105) may conveniently be mounted on a tubular sleeve (104) which is slidable and rotatable on the guidewire (101) between spaced-apart stops (106, 120) on the guidewire (101) which allows some manipulation of the guidewire independently of the filter when the filter is in use.

Patent CA-2460536-A1 (CA)
Inventor: MILLER JEREMY P
IPC: A23B4/06
Filed: 2002-09-17
Abstract: On-the-bone tenderization of a dressed freshly slaughtered unboned poultry bird is accelerated by rapidly cooling at least the breast meat of said bird by exposure to a cooling temperature of at most -10 ~C to provide a frozen crust on the breast and a substantial temperature gradient through the breast meat and reducing the rate at which the breast is cooled to reduce the temperature gradient whilst maintaining the surface temperature of the breast meat below -2 ~C for sufficient time to freeze only a portion of the water content of the breast meat and thereby tenderize the meat. The meat of the tenderized bird is preferably warmed towards an equilibration temperature of from 0 ~C to 5 ~C. It is understood that reduction of maturation time occurs because a portion of the water in the meat freezes thereby concentrating the salts and other solutes in the remaining liquid water. This concentration effect appears to initiate chemical reactions that accelerate the usual tenderization mechanisms such as rigor mortis and autodigestion.
