摘要： A signal generator circuit having enhanced control resolution includes a variable frequency oscillator having a first control input adapted to receive a first signal and at least a second control input adapted to receive a second signal. The second signal is afforded a weight which is substantially equal to a weight of a least significant bit of the first signal. The variable frequency oscillator is operative to generate an output signal having a frequency which varies as a function of the first and second signals. The signal generator circuit further includes a first counter, a first divider and a modulation circuit. The first counter is configurable for generating an output count based at least in part on a difference between a third signal presented to the signal generator circuit and a fourth signal indicative of the output signal, the output count including the first signal. The first divider has a selectable divide value associated therewith and is configurable for receiving the output signal and for generating the fourth signal based on the divide value. The modulation circuit is adapted to receive at least a portion of the output count and the fourth signal and to generate the second signal as a function of the output count and the fourth signal.

摘要： The ablation catheter is comprised of a guiding catheter and an inner catheter. The guiding catheter is comprised of a shaft section which is attached to an articulating section at its distal end and a first handle at its proximal end. The inner catheter is comprised of an elongated central shaft, an electrode assembly attached to the distal end of the central shaft, and a second handle attached to the proximal end of the central shaft. The electrode assembly is comprised of a flexible plastic catheter tube having an outer surface, a porous tip electrode, and at least one linear electrode carried on the outer surface of the catheter tube. The electrode assembly is articulated to better align the electrode assembly to the generally arcuate shape of the inner chambers of the heart.

摘要： A blood containment device for use with a vascular entry needle provides visual and tactile confirmation that a blood vessel has been properly entered. The device includes a blood visualization chamber defined by a compliant member which provides a visual indication that a needle connected to the device has accessed a selected blood vessel. The blood visualization chamber is vented to allow air to escape therefrom as it is displaced by blood entering the visualization chamber, while a gas permeable membrane in communication with the vent to prevent significant blood from escaping from the blood containment device. A sealing member formed on an outer surface at one end of the compliant member works in conjunction with the gas permeable membrane to prevent significant leakage of blood from the device. The compliant member pulsates with changes in blood pressure, thereby providing continuous tactile confirmation that the needle tip is properly positioned within the selected blood vessel. The device allows passage therethrough of an elongated medical instrument such as catheterization apparatus while preventing significant blood leakage from the device.

摘要： A hemostasis valve which includes a tubular body having a lumen therethrough and an elongated housing attached to the tubular body. The body has a recess formed in one end. The housing has a longitudinal bore at one end and a compression chamber formed at another end which communicates with the bore. A resilient seal which comprises a cone-shaped membrane portion disposed in the recess for substantially blocking and controlling the loss of body fluids from the lumen. A compressible second seal for selectively opening and closing the bore in response to a compressive force is disposed in the compression chamber. The compressible seal has a longitudinal first passageway that communicates with the bore and a raised annular portion which serves as a selective opening to the bore. The compressible seal responds to compressive forces so as to reduce or increase the size of the opening provided by the raised annular portion to selectively seal or unseal the bore. The hemostasis valve includes a rotatable end cap configured to exert a compressive force on the compressible seal when rotated in one direction relative to the housing, and releases the compressive force when rotated in an opposite direction. The compressible seal is configured to allow an instrument accessing the lumen to be repositioned or removed while maintaining an adequate seal capable of preventing substantially all loss of the body fluids beyond the compressible seal without the user having to rotate the end cap to release the compressive force acting on the compressible seal.

摘要： An oximeter apparatus especially adapted to reflectance oximetry includes a sensor having a red LED, an infrared LED and a photosensor resiliently mounted in a carrier to provide constant linear pressure characteristics. The LED's and photodetector are fixed to a flexible circuit board. The d.c. components of the reflectance signals are fed back to control the brightness of the LED's A.c. component signals from the photodetector are rejected in the determination of oxygen saturation when the red and infrared a.c. components differ by more than a determined amount. The difference between the maximum and minimum values of each pulse is employed in the determination of oxygen saturation, with two measurements being taken for each pulse.
