In the present invention, a catheter identification system for providing information about one or more attributes of a catheter connectable to an electrophysiology (EP) recording or mapping system includes a catheter, a resistor network operably connected to the catheter, the resistor network including at least one identification resistor and an identification resistor measurement circuit operably connected to the catheter and configured to send an identification signal through the at least one resistor in the resistor network to retrieve an altered identification signal from the identification resistor, where the altered identification signal provides information on an attribute of the catheter.

A rack for holding at least one medical device, the rack comprises a multiplicity of interfaces for connecting at least one medical device to the rack. Herein, a channel identification device is provided which is constituted to assign an identification code to each of the multiplicity of interfaces and is operable to provide, for a medical device connected with one of the multiplicity of interfaces, the identification code associated with the interface to the medical device or a control device connected to the medical device. In this way, a rack for holding at least one medical device is provided which in an easy manner allows for the identification of the topological position of a medical device on a rack or a system of racks.

A physiological signal monitoring device includes a biosensor, and a transmitter including a bottom casing, a processing unit and a battery. The bottom casing has a first stepped section, a second stepped section, and a riser section interconnecting the first stepped section and the second stepped section. The processing unit corresponds in position to the first stepped section. The battery corresponds in position to the first stepped section, and is configured not to overlap the processing unit in a direction of a first axis so as to reduce a thickness of the transmitter.

A pocket-sized apparatus for carrying out bioimpedance measurements at home includes: a closed box-like casing (1), which contains a printed circuit board (2), an microprocessor integrated control unit (3), and an integrated circuit bioimpedance meter device (4), interfaced to the integrated control unit (3).

A plurality of electrodes (11), arranged outside said casing (1) carry electrical signals to/from the bioimpedance meter device (4); a multi-pin connector (7), secured to the printed circuit board (2) and electrically connected to the control unit (3) and the bioimpedance meter device (4), can also be connected to a dedicated charging cable.

Status indicator means (8) are also provided, which are driven by the control unit (3) and visible from outside the casing (1).

An application for a portable personal terminal (20) connects (10) with the control unit (3) and acquires data produced by the bioimpedance meter device (4) for display.

A catheter is disclosed comprising: a connector including a plurality of first contacts and one or more second contacts; a shaft including a plurality of electrodes, each electrode being coupled to a different one of the plurality of first contacts; a memory coupled to at least one of the second contacts, wherein the memory is configured to: store a pinout map identifying an order in which the plurality of electrodes is coupled to the plurality of first contacts; and provide the pinout map to an external device via one or more of the second contacts after the connector is coupled to the external device.

Systems, devices and methods for advanced electrode management in neurological monitoring applications include receiving sockets configured to receive connectors having groups of electrodes. The physician is not required to manually map each electrode with its corresponding input channel. Electrodes are coupled to the corresponding input channels in groups through connectors having a unique identification (ID). The system is configured to read the unique ID of each connector and establish its identity. Based on the ID, the system configures itself to automatically correlate or associate each electrode with its corresponding input channel when the connectors are first inserted into the receiving sockets, and again if the connectors are removed and re-inserted into different positions in the receiving sockets, to insure the electrodes are always mapped to the same input channels.

A insertion module includes a main body, an auxiliary insertion seat, an insertion needle assembly and a sensor assembly. The main body has a plurality of slide grooves. The auxiliary insertion seat has a base portion, and a plurality of wing portions. The insertion needle assembly is fixed through the interference between the wing portions and wall surfaces of the slide grooves, such that the insertion needle is prevented from being oblique to an insertion direction before the insertion needle is inserted into a host.

In the present invention, a medical device authorization system is employed to associate software contained on a medical computing system/computer, such as an EP mapping and recording system, that pertains to a specific medical device, e.g., a catheter, connected to the computer such that the software is only utilized by the computer in conjunction with a catheter that is authorized for use with the computer. The authorization system utilizes an analog authorization waveform/signal that is mixed with the analog device/catheter measured signals transmitted to the computer. The authorization waveform distorts the measured signals in a manner that renders the signals able to be displayed by the system but unusable, unless the computer includes a signal filter operably connected to the device/catheter interface that is configured to remove the interfering authorization waveform from the measured signal.

In the present invention, a configuration system for an electrophysiology (EP) study system provides the physician with the ability to input or select the particular procedure to be performed utilizing the EP system, such as performing an ablation procedure, a pacing procedure, or a diagnostic procedure, among others based on the clinical objective of the procedure. Based on the selection of the procedure to be performed, the EP system can handle the selection and switching of different filter selections for a physiological signal to achieve an optimal signal profile having a clinically acceptable display regardless of acquisition conditions with the minimum of user intervention, or knowledge. These selections may be automatically derived, or manually selected, or over-ridden by the user as needed within any typically, or atypical procedural workflow.

In electrocardiography (ECG) system, a patient cable connecting one or more electrodes to a processing device for processing ECG signals may include one or more electrode connectors mechanically keyed to respective electrodes and/or a device connector mechanically and/or electronically keyed to a cable connector of the processing device. In some embodiments, keying between the cable and electrode is achieved, for example, with an electrode including a hollow-post portion that defines a bore in conjunction with a post protruding from an arm of the electrode connector that is sized to fit within the bore.
