摘要:
A system and method for determining patient-specific implantable medical device programming parameters are presented. A set of physiological measures collected through a plurality of sensors monitoring physiological functions in a patient are assimilated. The physiological measures set are analyzed to identify physiological idiosyncrasies specific to the patient and to optimize the therapy to be delivered through an implantable medical device. A patient profile is formed including a plurality of programming parameters and the patient profile is preprogrammed into the implantable medical device prior to implantation in the patient.
摘要:
An apparatus and method for adjusting the performance of an implanted device based on data including contextual information. Contextual information, including operational and performance data concerning the implanted device as well as the patient with the implanted device, is stored by a portable electronic device. In one embodiment, the portable electronic device is adapted for battery operation and includes a personal digital assistant (PDA). The portable electronic device is adapted for use as an interface to conduct wireless communications with the implanted device. In one embodiment, the portable electronic device interfaces with a clinical programmer for use by a physician.
摘要:
A method for monitoring a biological cardiac pacemaker is provided. The method may include stimulating a heart at a region selected for implantation of a biological pacemaker and sensing at least one electrical signal indicative of a cardiac depolarization originating in the region selected for implantation of the biological pacemaker. The method may further include sensing at least one subsequent electrical signal produced by the heart and determining if the subsequent electrical signal originated in the region selected for the biological pacemaker or another region of the heart. In an alternative embodiment, the method may include determining a template time difference between two points on cardiac complexes sensed in two or more different cardiac locations during normal sinus rhythm. The method may further include determining a time difference between two points on a subsequent cardiac complex sensed in two or more different cardiac locations. The time differences may be compared to determine if the subsequently-sensed cardiac complex originates in a left ventricular biological pacemaker site or in another cardiac site.
摘要:
A system is provided for stimulating one or more cells, wherein the stimulation is sub-threshold and may alter a transmembrane potential of the one or more cells. For some populations of cells it may be possible to affect the transmembrane potential to gain a therapeutic benefit. Cells of the sino-atrial node spontaneously depolarize predominantly due to the slow depolarization of transmembrane potential. The present system may provide sino-atrial cells with a local field stimulation that while not eliciting an action potential may nonetheless alter local transmembrane potential. Such alteration of transmembrane potential may permit an increase or decrease in a rate of depolarization, and hence modify heart rate.
摘要:
A system and method for transacting an automated patient communications session is described. A patent health condition is monitored by regularly collecting physiological measures through an implantable medical device. A patient communications session is activated through a patient communications interface including, an implantable microphone and an implantable speaker in response to a patient-provided activation code. An identification of the patient is authenticated based on pre-defined uniquely identifying patient characteristics. Spoken patient information is received through the implantable microphone and verbal system information is played through the implantable speaker. The patient communications session is terminated by closing the patient communications interface. The physiological measures and the spoken patient information are sent.
摘要:
A cardiac electro-stimulatory device and method for operating same in which stimulation pulses are distributed among a plurality of electrodes fixed at different sites of the myocardium in order to reduce myocardial hypertrophy brought about by repeated pacing at a single site and/or increase myocardial contractility. In order to spatially and temporally distribute the stimulation, the pulses are delivered through a switchable pulse output configuration during a single cardiac cycle, with each configuration comprising one or more electrodes fixed to different sites in the myocardium.
摘要:
A method and apparatus for delivering anti-tachycardia pacing in an adaptive manner is disclosed. A cardiac rhythm management device, such as an implantable pacemaker, having anti-tachycardia pacing capability delivers anti-tachycardia pacing therapy in accordance with a selected pacing protocol upon detection of a terminable arrhythmia. The protocol is selected from a library of available protocols. A record of the successes and failures of each available protocol in converting tachyarrhythmias is maintained in a result table for use in selecting the protocol.
摘要:
An implantable medical device such as a cardiac pacemaker or implantable cardioverter/defibrillator with the capability of receiving communications in the form of speech spoken by the patient. An acoustic transducer is incorporated within the device which along with associated filtering circuitry enables the voice communication to be used to affect the operation of the device or recorded for later playback.

An apparatus for providing on-patient communication is described. An implantable medical device including a sensor of physiometry is implanted in a patient. A communication module is remotely interconnected to an interrogation device external to the patient's body and the physiometry is exchanged with the interrogation device. Spoken communication from the patient is received by an implantable microphone including a communication module and is relayed to the interrogation device. voice prompts received from the interrogation device are played by An implantable speaker including a communication module. Pre-defined uniquely identifying patient characteristics are further included with at least one of the implantable medical device, implantable microphone, and implantable speaker and the characteristics are presented on demand by the communication module of the implantable medical device, implantable microphone, and implantable speaker.
