Excisional biopsy devices and methods

InactiveUS6863676B2Efficiently and safely exciseMinimize complicationCannulasSurgical needlesUltrasonic sensorTissue Collection
An excisional biopsy system includes a tubular member that has a proximal end and a distal end in which one or more windows are defined. A first removable probe has a proximal portion that includes a cutting tool extender and a distal portion that includes a cutting tool. The first removable probe may be configured to fit at least partially within the tubular member to enable the cutting tool to selectively bow out of and to retract within one of the windows when the cutting tool extender is activated. A second removable probe has a proximal section that includes a tissue collection device extender and a distal section that includes a tissue collection device. The second removable probe may also be configured to fit at least partially within the tubular member to enable the tissue collection device to extend out of and to retract within one of the windows when the tissue collection device extender is activated. A third removable probe may also be provided. The third removable probe may also be configured to fit at least partially within the tubular member and may include an imaging device, such as an ultrasound transducer, mounted therein. By selectively activating the cutting tool and the tissue collection device while rotating the excisional device, a tissue specimen may be cut from the surrounding tissue and collected for later analysis.

Excisional biopsy devices and methods

An excisional biopsy device includes a tubular member having a window near a distal tip thereof; a cutting tool, a distal end of the cutting tool being attached near the distal tip of the tubular member, at least a distal portion of the cutting tool being configured to selectively bow out of the window and to retract within the window; and a tissue collection device externally attached at least to the tubular member, the tissue collection device collecting tissue excised by the cutting tool as the biopsy device is rotated and the cutting tool is bowed. An excision al biopsy method for soft tissue includes the steps of inserting a generally tubular member into the tissue, the tubular member including a cutting tool adapted to selectively bow away from the tubular member and an external tissue collection device near a distal tip of the tubular member; rotating the tubular member; selectively varying a degree of bowing of the cutting tool; collecting tissue severed by the cutting tool in the tissue collection device; and retracting the tubular member from the soft tissue. The tubular member may include an imaging transducer and the method may include the step of displaying information received from the transducer on a display device and the step of varying the degree of bowing of the cutting tool based upon the displayed information from the imaging transducer. Alternatively, the imaging transducer may be disposed within a removable transducer core adapted to fit within the tubular member.

Distributed message engines and systems

Systems and methods that facilitate messaging capabilities within a unified plant model (UPM) via employing a plurality of message engines that collaborate in such system. Linkage can be provided among the plurality of message engines, to provide real time interaction among the message engines / services, wherein each message engine normalizes messaging of various messaging protocols and formats. Also various systems of the UPM can map thereto—and provide a consistent interface where events are sent / received consistently across the system.

Electrically operated viscous fluid dispensing apparatus and method

InactiveUS6318599B2Improved and more consistent dispensingNarrow downTemperatue controlPretreated surfacesEngineeringElectromagnetic field
An electrically operated fluid dispenser for dispensing a pattern of viscous fluid onto a substrate during a run mode. The dispenser is turned off and does not dispense the viscous fluid during a standby mode of operation. The dispenser includes a dispenser body having an outlet and an armature disposed in the dispenser body for movement between an opened position allowing a fluid flow from the outlet and a closed position preventing the fluid flow from the outlet. A coil is mounted adjacent the armature and selectively generates an electromagnetic field for moving the armature between the opened and closed positions. A controller includes different apparatus and methods for using the coil as a heater as well as providing other heat transfer devices on the dispensing valve to maintain a constant temperature either, during only the run mode or, during both, the run and the standby modes. The above dispensing valve heating control facilitates a design of an electrically operated fluid dispenser having a body with a fluid passage intersecting first and second sides of the body and a dispensing outlet in fluid communication with the fluid passage. The dispenser includes a heater and has feed member mounted to the first side of the body with one end of the fluid passage in the feed plate fluidly connecting with one end of the fluid passage in the dispenser body. The dispenser also has an cap mounted to the second side of the dispenser body to terminate the fluid passage on the second side of the dispenser body.

Evolvable hardware implementation method based on trend-type compact genetic algorithm

The invention relates to an evolvable hardware implementation method based on a trend-type compact genetic algorithm, and the method comprises the following steps of: 1) obtaining configuration parameters of an actual programmable logic device; 2) mapping the configuration parameters of the actual programmable logic device and forming into chromosome individuals; 3) calculating the fitness of thecurrent chromosome individuals; and 4) identifying whether to terminate the evolvement according to the situation of the fitness. The evolvable hardware implementation method based on the trend-type compact genetic algorithm can be used for enhancing the search capability of a hardware configuration bit string, increasing the diversity of a candidacy solution space, obtaining high-quality and optimal hardware configuration structure bit string more fast, greatly increasing the convergence speed, reducing the time required by obtaining an optimal hardware circuit structure and enhancing the real-time performance of the actual evolvable hardware.
