AI Technical Summary

Problems solved by technology

The many implant sites compatible with ICMs and leadless pacemaker systems mean that determining which axis of the multi-axis accelerometer within the device is optimally aligned with an overall physiological reference (e.g. head-to-toe vector) is critical for accessory feature support Alignment is more challenging

Embodiment Construction

[0076] figure 1 A schematic illustration of a medical system 1 is shown comprising at least an implantable medical device (also referred to as an implant) in the form of an intracardiac rhythm system 5 (also referred to herein as an intracardiac pacemaker). In particular, the intracardiac pacemaker 5 comprises a housing 100 surrounding an energy storage body 102 (eg a battery), an electronic module 103 and a communication unit 104 . Housing 100 may include titanium or may be made of titanium.

[0077] At the distal end of the housing 100, a first electrode 106 (also referred to as a pacing electrode) is provided. In the proximal region of the housing 100, a second electrode 101 (also referred to as a sensing electrode) is arranged. The second electrode 101 may be formed as a ring electrode.

[0078] The pacemaker system 5 may be secured to cardiac tissue by a fixation element 105 . The fixing elements may be formed as tines. It may comprise or be made of Nitinol. In one ...

Abstract

The present disclosure relates to a medical system (1), comprising at least an implantable medical device (5), and a multi-axis accelerometer (6) comprised by the implantable medical device (5) for measuring an acceleration of the implantable medical device (5) along a plurality of vectors (V1, V2, V3), wherein the multi-axis accelerometer (6) is configured to provide for each vector (V1, V2, V3) a signal indicative of the acceleration of the implantable medical device (5) in the direction of the respective vector (V1, V2, V3).The medical system (1) is configured to assess said signals to automatically select or propose a vector of said plurality of vectors (V1, V2, V3) that comprises the best alignment with a pre-defined vector (g).

Description

technical field [0001] The present disclosure relates to a medical system and corresponding method. Background technique [0002] Some implantable medical devices (IMDs) include accelerometers to detect motion / activity of the patient, for example to adapt the pacing rate of the pacemaker when increased activity of the patient is detected. [0003] Multi-axis accelerometers allow detection of motion with the ability to best measure such motion by collecting data acquired by an on-chip axis (or axes) that is optimally aligned with the motion vector of interest. In its simplest form, data collected from a single axis requires the least amount of system overhead (eg, current budget, calculations, etc.) to report motion in a specified direction (or inverse, since the polarity of motion along the axis is not important). Alternatively, in the absence of a single on-chip axis that is well aligned with the direction of motion of interest, data collected from many axes can be combine...
