    摘要： An electrophoretic system is provided which allows for carrying out electrophoresis while monitoring and regulating the temperature and the electrical field gradient in the gel. In addition, photometric monitoring is provided so as to monitor the progress of the electrophoretic separation and vary conditions to change the progress as desired. A computer is employed which receives the signals from the electrophoretic and photometric apparatuses and regulates temperature and voltage to either maintain conditions, or change the conditions to vary the progress of the electrophoresis. Gel molds are provided for forming the lanes in a gel plate, as well as a light module, for reading the bands present in the gel lanes with the photometer.

    摘要： A medical device for managing tissue in an organ, such as the stomach, for retracting or positioning tissue and related organs to allow certain regions of the stomach to be acquired for a gastroplasty procedure. The medical device includes an elongated body having a proximal end and a distal end, and a retractor section disposed at or near the distal end. The retractor section is adapted to be moveable from a delivery position to a retraction position to move or manage the tissue of the stomach. The retraction device can be configured for use with a second therapeutic device or such a therapeutic device may have a retraction device integrated within it or adapted for cooperative use therewith.

    摘要： A steerable, tendon-driven endoscope is described herein. The endoscope has an elongated body with a manually or selectively steerable distal portion and an automatically controlled, segmented proximal portion. The steerable distal portion and the segment of the controllable portion are actuated by at least two tendons. As the endoscope is advanced, the user maneuvers the distal portion, and a motion controller actuates tendons in the segmented proximal portion so that the proximal portion assumes the selected curve of the selectively steerable distal portion. By this method the selected curves are propagated along the endoscope body so that the endoscope largely conforms to the pathway selected. When the endoscope is withdrawn proximally, the selected curves can propagate distally along the endoscope body. This allows the endoscope to negotiate tortuous curves along a desired path through or around and between organs within the body.

    摘要： Methods and apparatuses for temperature modification of a patient, or selected regions thereof, including an induced state of hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette of any one of several disclosed variations is attached to the circulatory flow lines of the catheter, the heat exchange cassette being sized to engage a cavity within one of various described re-usable control units. The control units include a heater/cooler device, a user input device, and a processor connected to receive input from various sensors around the body and the system. The heater/cooler device may be thermoelectric to enable both heating and cooling based on polarity. A temperature control scheme for ramping the body temperature up or down without overshoot is provided. The disposable heat exchange cassettes may include an integral pump head that engages with a pump drive mechanism within the re-usable control unit. More than one control unit may be provided to receive the same heat exchange cassette so that a large capacity control unit can be used initially, and a smaller, battery-powered unit can be substituted once the patient reaches the desired target temperature.
