    摘要: This disclosure describes techniques for configuring an IMD into the exposure operating mode. Prior to a medical procedure that generates a disruptive energy field, such as an MRI scan, an electronic prescription is configured to indicate that the IMD is authorized for the medical procedure that includes a disruptive energy field. The electronic prescription includes one or more designated bits within a storage element of the IMD. When the patient in which the IMD is implanted arrives for the medical procedure, a user (such as an MRI operator) interacts with a telemetry device to determine whether the electronic prescription is configured. Upon determining that the electronic prescription is configured, the IMD transitions into the exposure operating mode designed for operation in the disruptive energy field. In this manner, the electronic prescription confirms to the user that that the IMD has been checked for suitability for operation during the medical procedure.

    摘要: In a pacemaker, a method and apparatus for providing rate response in proportion to the patient's metabolic demand for cardiac output as determined in response to the patient's breathing rate or respiratory minute ventilation or contraction strength, optionally augmented by the patient's activity level. An implantable pulse generator (IPG) has one or more pacing leads having a proximal end coupled to the IPG and a distal end in contact with a patient's heart. A pressure wave transducer mounted in the IPG in relation to the proximal end of the pacing lead senses pressure waves transmitted from the distal end of the pacing lead to the proximal end thereof. The pressure waves originate from disturbances imparted to the lead by heart contractions and breathing. A further isolated, reference sensor is also incorporated into the IPG in a similar fashion. An activity signal processor is coupled to the pressure wave or reference sensor for providing a patient activity physiologic signal. A respiration signal processor is coupled to said pressure wave and reference transducers for nulling out common mode noise and providing physiologic respiration rate and/or respiratory minute ventilation signals. A contraction strength signal processor is coupled to said pressure wave and reference transducers for nulling out common mode noise and providing physiologic contraction strength signals. Pacing rate control circuitry is responsive to one or more of the physiologic signals for setting the pacing rate to meed the metabolic demand.

    摘要: In an implanted medical device, a method and apparatus for detecting pressure waves caused by movement of a body organ, muscle group, limb or the like and transmitted through a catheter or lead body to the implanted medical device employing a pressure wave transducer mounted in relation to the proximal end of the catheter or lead to detect the transmitted pressure waves. The system may also include a reference transducer having the same pressure wave response characteristics as the pressure wave transducer but isolated from the proximal connector end for providing a reference signal including common mode pressure wave noise that both transducers are simultaneously subjected to. The pressure wave signal and the reference signal are preferably amplified, bandpass filtered to the body pressure wave of interest and stored, telemetered out or used to trigger a device operation. The pressure and reference wave transducers preferably are piezoelectric crystal transducers or accelerometers in direct or indirect mechanical contact with the proximal connector end of the catheter and is encapsulated from the body within a device connector assembly. Preferably, the catheter is a lead extending into direct or indirect contact with the patient's heart. Cardiac pressure waves and respiration pressure waves are both transmitted proximally through the lead body to the pressure wave transducer. Pressure wave signals may be derived in parallel to detect particular characteristics of the cardiac and/or respiratory cycle to provide timing signal(s) for controlling the device operations.

    摘要: A capture verification system for a cardiac pacemaker comprising an implantable pulse generator (IPG) and one or more pacing leads having a proximal end coupled to the IPG and a distal end in contact with a patient's heart. The capture verification system employs a pressure wave sensor mounted in the IPG in relation to the proximal end of the pacing lead for sensing pressure waves transmitted from the distal end of the pacing lead to the proximal end thereof. The pressure waves include characteristic sounds of heart contraction and/or distal end lead motion caused by the contraction motion of the patient's heart that are transmitted along the lead body to the active sensor. A further isolated, reference sensor is also incorporated into the IPG in a similar fashion. Signal processors are coupled to the pressure wave and reference sensors for nulling out common mode noise.

    摘要: A method and apparatus for selectively controlling an oscillator-driven implantable stimulator to operate either in a quiescent state, in response to a command from an external communicating device, or in an active state in response either to removal of an activation pin or to an activating command from an external communicating device. Upon completion of manufacture of the stimulator, and before being placed on a shelf to await implantation in a patient, the activation pin is inserted into the stimulator and the external communicating device is triggered to send a deactivating command to the stimulator. The stimulator responds by generally disabling current sources to stimulator circuits, while maintaining current sources to a wake up circuit of the stimulator that is associated with communication operations. The stimulator is activated by subsequently transmitting an activating command from an external communicating device to the implantable stimulator, or by removing the activation pin.
