A power source of an implantable medical device (IMD) is connected to one or more components that perform various functions of the IMD via an acoustic switching circuit. The acoustic switching circuit may include one or more switches that when open disconnect the one or more components from the power source and when closed connect the one or more components to the power source to activate the one or more components. Various techniques for connecting the components to the power source are described. These techniques aim to reduce the likelihood of inadvertently connecting the power source to the one or more components in response to acoustical signals from a source of interference.

Acoustic activation of components of an implantable medical device

An volume of a patient can be mapped with a system operable to identify a plurality of locations and save a plurality of locations of a mapping instrument. The mapping instrument can include one or more electrodes that can sense a voltage that can be correlated to a three dimensional location of the electrode at the time of the sensing or measurement. Therefore, a map of a volume can be determined based upon the sensing of the plurality of points without the use of other imaging devices. An implantable medical device can then be navigated relative to the mapping data.

Multiple sensor input for structure identification

Disclosed herein are various embodiments of methods, systems and devices for detecting atrial fibrillation (AF) in a patient. According to one embodiment, a hand-held atrial fibrillation detection device acquires an electrocardiogram (ECG) from the patient over a predetermined period of time. After acquiring the ECG from the patient, the device processes and analyzes the ECG and makes a determination of whether or not the patient has AF.

Disclosed herein are various embodiments of methods, systems and devices for detecting atrial fibrillation (AF) in a patient. According to one embodiment, a patient places his or her left and right hands around left and right electrodes and a hand-held atrial fibrillation detection device acquires an electrocardiogram (ECG) from the patient over a predetermined period of time such as, by way of example, one minute. After acquiring the ECG from the patient, the device processes and analyzes the ECG and makes a determination of whether the patient has AF. The device may further be configured to provide a visual or audio indication of whether the patient has AF, or does not have AF. The device may be employed in a health care provider's office without the need for complicated or expensive diagnostic equipment, and is capable of providing an on-the-spot and low-cost diagnosis of AF. The device may further be connected to a physician's computer in the office, which may be configured to store the results of the analysis and the patient's ECG, and which may further be configured to carry out additional processing and analyses of the acquired and processed data. Moreover, the physician's computer may be operably connected to a remote server configured to store, process and analyze the ECG and the results provided by the hand-held device.

An integrated activation system for an implantable medical device (IMD) sharing a power source, the activation system comprising a switching circuit having first and second inputs and having an output coupled to the acute use device, a gating element coupled to the first input and configured to gate power from the power source to the switching circuit, and a sensing element coupled to the second input of the switching circuit. The sensing element is configured to sense an activation condition, enable an operation interval of the switching circuit, and transmit a signal to the switching circuit during the activation condition. The switching circuit is configured to transmit power to the acute use device upon receipt of a pre-determined number of signals from the sensing element.

A sensor is disposed within a pin portion of a feedthrough assembly. The feedthrough assembly provides a hermetically sealed enclosure that protects the sensor. In one embodiment, the sensor is a temperature sensor and the feedthrough assembly thermally isolates the sensor from the surrounding housing or enclosure.
