A third embodiment combines a (SOS), an implantable power and communication unit (PCU) electrically coupled to the SOS, and a drug delivery and communications catheter for communicating the SOS with the PCU and for communicating the exterior source of the drug to the SOS. A fourth embodiment combines a ventricular catheter with a CSF accessible chamber and drug delivery port; and an implantable stand-alone skull-mounted drug and pressure sensor (SPS).

Skull-mounted drug and pressure sensor

A system may include a target implantable medical device (IMD) and an external device configured to selectively communicate with the target IMD. The external device may include a communication module configured to communicate with the target IMD, a response analysis module configured to receive and analyze a target response signal from the target IMD and other response signals from other IMDS, and a power adjustment module configured to receive one or more power-adjustment request signals from the response analysis module. The power adjustment module is configured to adaptively adjust a power of a transmission request over a first frequency band based on the one or more power-adjustment request signals until the response analysis module receives only the target response signal from the target IMD.

System and method for selectively communicating with an implantable medical device

Dynamically switching between different external RF transceivers for communication with an implantable medical device maintains high communication quality in the face of interference, fading, detuning, or other adverse wireless communication conditions. Quality information associated with communications between an implantable medical device and different external devices is monitored to select one of these external devices to conduct subsequent communication with the implantable medical device. This monitoring is conducted on a repeated basis such that communication is switched to a different RF transceiver whenever such an RF transceiver is able to achieve a higher quality communication than the currently selected RF transceiver. In some embodiments, RF transceivers are deployed in different devices. For example, one or more RF transceivers may be deployed at a portable programmer (e.g., in the form of a computer tablet) and one or more other RF transceivers may be deployed at an associated base station.

RF transceiver hopping for communication with implantable medical device

Disclosed herein is a shield for shielding a telemetry wand from electromagnetical interference capable of interfering with telemetry communications between the telemetry wand and an AIMD in a patient. The telemetry wand may include a first side that is configured to be placed against a patient, a second side generally opposite the first side, a lateral side between the first and second sides, a hole extending between the first and second sides, and a cable extending from the lateral side. The shield may include a shell including a wall that defines a volume and an opening in the shell. The volume may be configured to receive therein the telemetry wand such that the second and lateral sides of the telemetry wand face respective portions of the wall and the first side faces the opening in the shell.

Exemplary external medical devices are configurable to communicate with an implantable medical device (IMD). One medical device includes multiple IMD telemetry ports operable to connect IMD telemetry mechanisms to the medical device. The medical device also includes a control unit configured to control the IMD telemetry mechanisms.

External medical device configurations for communicating with implantable medical devices

A method for connecting to a remote unit via a communications medium, determining a data transfer rate of the connection, setting a sampling rate between the remote unit and an implantable medical device at least in part as a function of the determined data transfer rate and receiving real time data from the remote unit via said communications medium.

Automatic data transmission rate adjustment

Patients fitted with an implantable medical device (IMD) must typically return to their medical providers for follow-up sessions where the medical provider retrieves data from the patient's IMD for analysis. A remote monitoring device is described to allow patients to complete a follow-up session from the comfort of their own home or from some other remote location. Specifically, a user interface employing various audio signals, light indicators, and tactile features is described to aid patients with hearing and/or visual disabilities during the remote follow-up session. Different light indicator states are used to aid hearing impaired patients. Different audio sound states are used to aid visually impaired patients. Furthermore, tactile features are used to aid hearing and/or visually impaired patients.

Remote transtelephonic monitor user interface

An external programmer is provided with the capability of automatically resetting the programming state of an implantable medical device to a previous programming state. To this end, the pacemaker maintains parameters representative of current and past programming states. In response to a physician-initiated reset function using an external programmer, the pacemaker transfers information pertaining to the programming states to the external programmer along with a pointer identifying the current state. The physician selects one of the previous programming states and the external programmer then updates the pointer to identify the selected state and transmits the pointer back to the pacemaker. The pacemaker accesses the programming parameters stored therein corresponding to the programming state identified by the new pointer and is reprogrammed. Accordingly, the programming state of the pacemaker is reset to the previous programming state without requiring manual reentry of the parameters. The external programmer may also be configured to enable the physician to modify parameters or to display differences between two or more programming states of the medical device. Also, the external programmer may be configured to enable the physician to merge parameters from two or more programming states to create a new programming state.

A system and method for identifying and displaying safety alert advisories. The system of the present invention automatically performs a comparison of identification data with a safety alert advisory. The system stores identification data in a plurality of dedicated fields. Each of the dedicated fields contains information related to the patient. Upon the telemetric retrieval of the data by an external programmer, the external programmer automatically cross-correlates the data in the dedicated fields with the safety alert advisories. Upon identification of a match between the data and one of the safety alert advisories, the identified safety alert advisory is displayed to a medical practitioner. In addition, the system provides a dedicated memory to store an advisory flag. The advisory flag is marked when the programmer identifies a safety alert condition that is relevant to one of the dedicated fields. When a subsequent external programmer retrieves the data from the dedicated fields, the external programmer can notify the medical practitioner that a safety alert advisory exists even though the safety alert advisory was never directly input into the subsequent external programmer.

An implantable stimulation device (ISD) for recording and displaying cardiac episode history for analyzing efficacy of cardiac therapy. The ISD applies anti-bradycardia therapy in patients who suffer from a slow heart rate, and antitachycardia therapy in patients who experience episodes of high heart rate and/or fibrillation. The ISD detects the occurrence of these episodes, applies the necessary therapy, and stores the chronology of these events in a special memory unit. An external device may be employed to telemetrically retrieve the stored data from the ISD memory unit, and display the data in a time-line fashion for analysis by a physician. The recordation of such data provides a valuable tool for the physician to track cardiac episode history and recommend the appropriate therapy for the patient.

An implantable device programmer includes a variety of features for allowing a clinician to perform an automated and customized follow-up examination of a patient having an implanted cardiac implantable device, the implantable device being of the type which captures and stores various types of diagnostic data for subsequent retrieval and evaluation. A custom protocol feature of the programmer allows the clinician pre-specify and then semi-automatically follow an ordered sequence of protocol steps, each protocol step involving the interrogation of the implantable device and the display by the programmer of associated implantable device data (such as a heart rate histogram, or the results of a ventricular capture test). When the clinician initiates a custom protocol, the programmer automatically retrieves all of the diagnostic data records of the protocol in the protocol order. This automatic retrieval is performed in the background, allowing the clinician to begin viewing the initial diagnostic data records of the protocol while the other items are being retrieved. Via a user interface of the programmer, the clinician can rapidly and efficiently sequence through the data display screens associated with the protocol, to thereby view the various diagnostic data records and/or perform the various diagnostic tests of the protocol.
