Disclosed is a respiratory cannula assembly to deliver and receive gases from a patient. The cannula assembly contains two oral prongs for delivering and receiving gases from the patient as well as at least one gas delivery nasal prong and at least one gas receiving nasal prong. The gas receiving nasal prong extends further into the patients nostril than the gas delivery nasal prong. The cannula assembly further contains a connector that aids in coupling to a medical device, the connector including independent oral and nasal moisture traps that remove moisture from exhaled patient gases.

Disclosed is a drug-delivery cassette for use with a drug delivery device. The cassette includes a main board and a luer site base portion connected to the main board for positioning a luer on the main board. A drip chamber is included on the main board to collect any drug that exits the luer when the luer is attached to the luer site portion. A deflectable sensor beam is positioned to detect the presence or absence of a luer in the luer site base portion. The drug-delivery cassette further includes a drug vial spike attachable to and detachable from the cassette main board that is connected to the luer by way of a drug delivery tube.

Disclosed is a device for coupling a respiratory cannula with a medical effector system. The coupling device consists of a plate with several ports for receiving respired gases from the respiratory cannula and for delivering oxygen or air to the respiratory cannula. The coupling device may directly or indirectly deliver the respired gases to a capnometry device located in the medical effector system. Also included is a port for delivering an audio signal from the medical effector system to an audio earpiece disposed proximate the ear of a patient.

Disclosed is an interface between a drug delivery cassette and a medical effector system. The cassette may be mounted to the medical effector system in such a way that a fluid tube located on the cassette is positioned adjacent to a pump located on the medical effector system. The medical effector system may purge the fluid line of air by activating the pump and forcing fluid through the fluid line until a sensor positioned to monitor the fluid line indicates that fluid and not air is present in the tube. To prevent air purging of the fluid tube when connected to the patient, the medical effector system prohibits air purging unless the drug delivery end portion of the fluid tube is in a designated storage site located on the cassette. This is accomplished with a position sensor at the storage site that monitors the position of the fluid tube.

Disclosed is a drug delivery infusion pump assembly containing a drug delivery pump, a drug delivery cassette, a pump door, and a housing adapted to receive a drug vial. A drug vial centering mechanism ensures varieties of drug vial sizes are compatible with this device. The drug delivery cassette is capable of being positioned on the drug delivery infusion pump assembly so the drug delivery pump will interface with a drug delivery tube located on the drug delivery cassette.

A conscious sedation system and a response testing apparatus for a conscious sedation system. A controller generates a request for a predetermined hand motion response from a patient and analyses at least a hand motion response made by the patient to the request to determine a level of sedation of the patient. The response testing apparatus includes a request assembly and a response assembly. The request assembly communicates to the patient the request generated by the controller. The response assembly senses the hand motion response and communicates the hand motion response to the controller.

A surgical stapler having an end effector with a reduced stacking height for its components to decrease the diameter of a trocar cannula or other access device during minimally invasive surgery is disclosed. The end effector includes an elongated channel containing a staple cartridge and an anvil movable toward and away from the channel. The anvil is movable to first, second and third fixed positions relative to the channel. The first fixed position is a closed position which eliminates clearance between the anvil and cartridge. The second fixed position is an open position for inserting tissue between the anvil and cartridge. The third fixed position is a clamped position where a tissue-clamping gap exists between the anvil and cartridge to properly clamp tissue. The elimination of clearance between the anvil and cartridge of the first fixed position of the anvil reduces the stacking height, and therefore enables the user to insert the stapler through a smaller diameter access opening.

A medical effector system comprised of a bedside unit and a procedure unit. The bedside unit contains a series of connection points for receiving inputs from a series of patient monitors. The procedure unit contains a patient monitoring and medical effector program, and a drug delivery pump or magnetic flux generator capable of delivering therapeutic energy to a patient. The medical effector system contains the capability to issue and receive a request from a non-sedated patient, issue and receive a request from a sedated patient and then to calculate a time difference. The medical effector program operates the pump or magnetic flux generator based upon at least some of the patient outputs and program inputs including a calculated time difference. A removable umbilical cable connects the two units and allows the output of the patient monitors as well as other information to travel between the two units.

The present invention is directed to an improved cable driven surgical biopsy device wherein a transmission assembly is disposed at a proximal end of the biopsy device. The transmission assembly being adapted to convert rotational motion of a cable entering the biopsy device of a substantially right angle into rotational energy to drive the axial cutter in the biopsy device.

An electrosurgical instrument is provided for cauterization and/or welding of tissue of varying impedance, thickness and vascularity especially in the performance of endoscopic procedures. The instrument compresses the tissue between one pole of a bipolar energy source located on one interfacing surface, and a second interfacing surface applying pressure in a predetermined range. A second pole is located one of the two interfacing surfaces. In a preferred embodiment, the second pole is located on the same interfacing surface as the first pole and an insulator electrically isolates the two poles. A preferred application of the invention is in a cutting instrument wherein a hemostatic line is formed along a cut line using RF energy.
