Abstract: A system records use of a structure deployed in operative association with heart tissue in a patient. An image controller generates an image of the structure while in use in the patient. An input receives data including information identifying the patient. An output processes the image in association with the data as a patient-specific, data base record for storage, retrieval, or manipulation.

Abstract: A medical system for limiting usage of a medical probe, such as, e.g., a catheter or surgical probe, is provided. The medical system includes a medical probe that includes electronic storage componentry for storage of data. The medical system further includes a control unit to which the medical probe is connected. The control unit is configured for writing and reading data to and from the electronic storage componentry of the medical probe when the medical probe is connected to the control unit. The control unit includes a clock that generates a time signal, which is used to determine an initial probe usage time and a reference time. The control unit further includes a control circuit that writes the initial probe usage time to the electronic storage componentry of the medical probe when the medical probe is initially operated. During a subsequent procedure, the control circuit reads the initial probe usage time from the electronic storage componentry.

Abstract: An interface is associated with a structure which, in use, is deployed in an interior body region of a patient. The structure includes an operative element coupled to a controller, which establishes an operating condition for the operative element to perform a diagnostic or therapeutic procedure in the interior body region. The interface generates a first display comprising an image of the structure at least partially while the operative element performs the procedure. The interface also generates a second display comprising one or more data fields reflecting the operating condition of the controller. The interface enables selection of the first display or the second display for viewing on a display screen.

Abstract: A medical system for limiting the re-use of a medical probe, such as, e.g., a catheter or a surgical probe, is provided. The medical system includes a medical probe that includes an electronic storage component for storing a probe identification code. The medical probe further includes a disabling circuit, the activation of which disables the electronic storage component. The medical system further includes a control unit, such as, e.g., an RF generator, for connection to the medical probe. The control unit includes control circuit that is configured for automatically reading the probe identification code from the electronic storage component and preventing the medical probe from being operated if the probe identification code is not approved. The control circuit is also configured for determining if the medical probe has been previously used.

Abstract: A system is used in association with a structure which, in use, is deployed in an interior body region. The structure includes an operative element. A switch matrix is coupled to the operative element. The switch matrix includes a plurality of inputs and a plurality of outputs. A controller is coupled to the switch matrix to control the switch matrix to couple the operative element to selected ones of the inputs and selected ones of the outputs in accordance with applied commands. An interface is coupled to the controller. The interface includes an input element to receive operator input and a processor to generate applied commands to the controller in response to operator input. The interface also includes an image controller to generate an image of the structure while coupled to the switch matrix. The image controller generates markers on the image in response to signals transmitted from the operative element through the switch matrix.

Abstract: A graphical user interface (GUI) is provided for assisting medical personnel in interpreting data collected by a multiple electrode catheter deployed within the body. The GUI generates and displays an image of the multiple electrode catheter. By manipulating appropriate controls, the medical personnel are able to change the orientation of the displayed image until it matches the orientation of the actual multiple electrode catheter as seen on a fluoroscope. Afterwards, the medical personnel can determine the relative position and orientation of the catheter by reference to the GUI generated image. To aid in interpreting data recovered by the catheter, the individual electrodes and splines are highlighted and labeled. Electrodes recovering particular types of physiological waveforms can be automatically identified and highlighted. Comments and anatomic landmarks can be inserted where desired to further assist in interpreting data.

Abstract: The present invention relates to a control system for use with an automated intravenous drug and fluid infusion system having plural pumping channels that operate independently for intravenously infusing drugs and fluid. The pumping channels are controlled by a microprocessor-based host controller that monitors each of the channels concurrently. In an exemplary embodiment, the system functions include identifying the particular drug that is to be pumped through a channel, preventing priming of a channel unless verification is provided that the channel is not connected to a patient and initiating the priming of each of the pumping channels independently.

Abstract: A drug identification and security apparatus usable in conjunction with an electronic drug delivery system having at least one drug channel therein, the apparatus providing a first interlock mechanism between a locking member of the apparatus and the drug delivery system to lock the upper and lower doors of the drug channel and to disengage the drug delivery system and prevent removal of a drug container/cassette assembly when the locking member is in a locked position.

Abstract: An assembly is described for accurately and precisely controlling the position of a plunger in a syringe to deliver precise fluid volumes. The assembly includes a motor coupled to a lead screw that drives a bearing block along a linear guide rod to move the plunger of the syringe in a linear fashion. The position of the plunger is accurately controlled by attaching a digital encoder to the rotating motor shaft. The encoder and associated electronics output to a controlling processor that generates a series of regular pulses, typically 300 to 500 responsive to each motor revolution. Utilizing appropriate gear ratios of the motor and the lead screw, the number of pulses per full syringe stroke in typical applications can be on the order of one hundred thousand. The final position and the motion of the plunger (velocity and acceleration) can be controlled to within a few encoder pulses, thus precisely controlling the rate of delivery of the fluid and the volume of the fluid actually delivered by the syringe.
