    摘要： A method is provided for obtaining cervical cell culture specimens. The method makes use of a test device which may be used in conjunction with the manual cervical examination prior to delivery. The device includes an elastically resilient sheath adapted to grip a finger and a sterile pad of absorbent material on one end adapted to collect and retain the cell culture specimen. A kit is provided as well, the kit including a support member for maintaining the device in an unrolled, elongated, unrolled configuration and is designed so as to maintain sterile conditions and minimize contamination during storage and transport.

    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 conduits 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 15″ 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, for example, 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.

    摘要： The invention provides devices and method for performing extremely small-scale, minimally-invasive microsurgery such as thoracoscopic coronary artery bypass grafting. The instruments of the invention utilize a symmetrical, forcep-like actuator which provides extremely precise actuator and control of the instrument and which mimics the feel of instruments used in conventional open surgical procedures. The instruments generally include a pair of coaxially arranged shafts, an end-effector at the distal ends of the shafts, and an actuator at the proximal ends of the shafts. The actuator includes a pair of arms pivotally coupled to one of either the outer or inner shalt, and a pair of links pivotally coupled at one end to the arms, and at a second end to the other of the shafts. The links are coupled to a proximal portion of the arms to maximize mechanical advantage and reduce interference. The actuator may be easily adapted for either pull-type or push-type actuation, and for either outer shaft or inner shaft translation. The end-effectors may have a variety of configurations, including needle drivers, forceps, scissors, and clip appliers.
