Abstract: A driven member of a metal peening machine is disclosed. The metal peening machine is configured to drive the driven member into contact with a work surface of a metal workpiece to deform the metal workpiece. The driven member includes a shaft with an impact end. The driven member includes least one of a plurality of impact features, an impact feature with a non-flat impact surface, a non-round impact feature, and an asymmetrical impact feature that is coupled to and protrudes from the impact end of the shaft. The at least one of the plurality of impact features, the impact feature with a non-flat impact surface, the non-round impact feature, and the asymmetrical impact feature define at least one impact surface to be driven into contact with the work surface of the metal workpiece.

Abstract: Method and apparatus are provided for processing and changing the physical characteristics of a metal workpiece into a final metal component. Predetermined processing parameters are established for achieving a final metal component. The metal workpiece is positioned securely on a support during the changing of the physical characteristics. Impacts are applied to a surface of the workpiece multiple times for achieving the final metal component while controlling the impacting with the predetermined processing parameters. A sensor is provided for continuously sensing the currently existing physical conditions of the workpiece during impacting. The predetermined processing parameters are changed into adjusted processing parameters and the impacts are changed in reaction to the currently existing physical conditions of the workpiece from the sensing and processing of the workpiece until the final metal component has been achieved.

Abstract: An apparatus and method are provided for changing physical characteristics of a workpiece which may have been pre-loaded before being further processed. The workpiece is supported in a fixed position during processing. A driven member applies multiple impacts to one surface of the workpiece. The driven member is operated within adjustable parameters. A controller, having the adjustable parameters, is operatively connected to the driven member for causing the driven member to apply multiple impacts against a surface of the workpiece while under the control of the pre-adjustable parameters for changing physical characteristics of the workpiece.

Abstract: A non-deforming deflectable multi-lumen catheter with an outer jacket having a deflectable distal end portion, an eccentric pull wire lumen, coil and shim embedded therein. The deflectable distal portion optionally having one or more transaxial notches in the external surface of the outer jacket. A functional device is disposed within the lumen of an inner tube substantially coaxial with the outer jacket of the catheter. The distal tip of the functional device egressible from the distal tip of the catheter, and upon deflection, automatically aligns with the distal tip of the catheter and functional device.

Abstract: A cryoprobe sheath has at least one positioning element that deploys and retracts to permit the insertion of the cryoprobe into a uterus without using ultrasound or fluoroscopy. Deployment of the positioning element(s) positions the cryoprobe within the uterus permitting even cooling to facilitate cryoablation. The positioning element(s) and sheath may be withdrawn either after tacking the cryoprobe in position by a momentary activation or after a complete activation cycle, with each positioning element pulling through frozen medium in its own track. A guide and filler tube may be employed to infuse the correct quantity of thermally conductive medium into the uterus for cryoablation. The guide and filler tube allows fluid volume and pressure to be measured to avoid inadvertently breaching the uterine wall.

Abstract: A modular drug delivery system for use by cardiothoracic surgeons and interventional cardiologists for delivery of molecular and cellular therapies that target genes, molecules and peptides. The regulated drug delivery devices comprise a modular mechanically actuated drug delivery module (DDM) that can be attached to either a surgical viewing endoscope hand-piece or specialized catheter for interventional procedures. The DDM provides metering of drugs to treatment sites and allows for quick interchangeability with other component parts such as a viewing scope end portion for MIS or other surgical procedures or a flexible catheter shaft for percutaneous procedures.
