US Patent:

54316928, Jul 11, 1995

Filed:

Aug 2, 1993

Appl. No.:

8/101508

Inventors:

Daniel L. Hansen - Aurora CO
Anthony J. Ujhazy - Denver CO

Assignee:

Telectronics Pacing Systems, Inc. - Englewood CO

International Classification:

A61N 1362

US Classification:

607 28

Abstract:

A cardiac stimulation device includes a system for testing lead polarity and determining whether the programmed polarity configuration is compatible with an attached pacing and sensing lead. The lead polarity test is based on a measurement of lead impedance performed during the delivery of a pacing pulse. Since the polarity test consists of lead impedance measurements for all polarity configurations, including incompatible configurations, the system provides for backup pacing pulses in a safe configuration to assure pacing support of a patient during all cardiac cycles.

Assignee:

Telectronics Pacing Systems, Inc. - Englewood CO

International Classification:

A61N 1362

US Classification:

607 16

Abstract:

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.

International Classification:

A61B 5/00
A61N 1/37

Abstract:

In situations in which an implantable medical device (e.g., a subcutaneous ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the subcutaneous ICD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the ICD and based on the sensed electrical signal, pacing pulses and adjusting operation to account for the detected pulses, e.g., blanking the sensed electrical signal or modifying a tachyarrhythmia detection algorithm. In one example, the ICD includes a first pace pulse detector configured to obtain a sensed electrical signal and analyze the sensed electrical signal to detect a first type of pulses having a first set of characteristics and a second pace pulse detector configured to obtain the sensed electrical signal and analyze the sensed electrical signal to detect a second type of pulses having a second set of characteristics.

Abstract:

In situations in which an implantable medical device (IMD) (e.g., an extravascular ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the IMD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the IMD and based on the sensed electrical signal, pacing pulses and adjusting operation to account for the detected pulses, e.g., blanking the sensed electrical signal or modifying a tachyarrhythmia detection algorithm. In one example, the IMD includes a pace pulse detector that detects, based on the processing of sensed electrical signals, delivery of a pacing pulse from a second implantable medical device and blank, based on the detection of the pacing pulse, the sensed electrical signal to remove the pacing pulse from the sensed electrical signal.
