Embodiment Construction

[0033] Disclosed herein are IMD systems and associated technologies for sensing physiological signals using a sensing device implanted at one location and triggering a therapy delivery device to deliver automated therapy to targeted patient tissue at a second location. The trigger signal is initiated by the sensing device and detected by a transducer included in the therapy delivery device. Automated therapy delivery is achieved from separate sensing devices and therapy delivery devices without requiring the two devices to be physically connected to each other. Among other things, eliminating the physical connection between the sensing components and therapy delivery components of the IMD system enables the use of minimally invasive implant procedures, miniaturization of the IMD system components and power supplies, and / or the elimination of certain components (such as medical leads, Sensing capabilities of therapy delivery devices and radio frequency (RF) transceivers in ther...

Abstract

A medical device system is configured to sense physiological events by a first device and control a transducer to emit trigger signals in response to the sensed physiological events. A second device detects the trigger signals and delivers therapeutic stimulation pulses in response to the trigger signals. The therapeutic stimulation pulses have a combined total time duration over the sensed physiological events that is greater than the combined total time duration of the trigger signals.

Description

technical field [0001] The present disclosure relates to an implantable medical device system and an associated method for delivering therapeutic stimulation pulses using a triggered therapeutic delivery device. Background technique [0002] Implantable pacemakers and cardioverter defibrillators (ICDs) are used to deliver electrical stimulation therapies to a patient's heart, such as bradycardia pacing, cardiac resynchronization therapy (CRT), antitachycardia pacing, and cardiac Cardioversion / defibrillation shock. Advances in medical device technology have resulted in ever smaller implantable devices. More recently, leadless intracardiac pacemakers have been proposed that can be implanted directly into the chambers of the heart. Elimination of venous leads, intracardiac leads has several advantages. For example, complications caused by interference associated with leads extending intravenously from a subcutaneous pacemaker bag into the heart can be eliminated. Other comp...
