A magnetic field sensor for a medical device, the magnetic sensor assembly comprising a substrate having a plurality of planar sections, wherein adjacent planar sections are joined by a transition section, and wherein the planar sections are arranged in a substantially C-shaped arrangement such that an inner surface of the magnetic field sensor is concave, and wherein the plurality of planar sections includes a first planar section oriented in a first plane and a second planar section oriented in a second plane orthogonal to the first plane. A first magneto-resistive (MR) sensor is mounted to the first planar section and defining a first axis of sensitivity, and a second MR sensor is mounted to the second planar section and defining a second axis of sensitivity that is orthogonal to the first axis of sensitivity.

Magnetic field sensor for a medical device

A sensor assembly includes a multilayer circuit, a first magnetic field sensor, and a second magnetic field sensor. The multilayer circuit extends between a proximal end and a distal end along a longitudinal axis. The multilayer circuit includes a plurality of electrical pads positioned at the proximal end. The first magnetic field sensor is coupled to the multilayer circuit and has a primary sensing direction aligned with the longitudinal axis. The second magnetic field sensor is coupled to the multilayer circuit and oriented with respect to the first magnetic field sensor such that the second magnetic field sensor has a primary sensing direction aligned with an axis orthogonal to the longitudinal axis.

This document discusses, among other things, systems and methods related to a flexible circuit buzzer apparatus, such as a buzzer apparatus for use in an implantable medical device. In an example, the buzzer apparatus can include a flexible circuit having a first dielectric layer. A conductive layer can be disposed on the first dielectric layer. A hole can be formed in the first dielectric layer, the conductive layer, or both. A buzzer including a first contact can be located proximate to the hole. A conductive via can be plated or deposited in the hole. At least the first contact can be electrically coupled to the conductive layer by the conductive via.

A sensor assembly includes a substrate including a first portion, a second portion, and a rolled section positioned between the first portion and the second portion. The sensor assembly further includes a first magnetic field sensor coupled to the first portion. The first magnetic field sensor has a primary sensing direction aligned with a longitudinal axis of the sensor assembly. The sensor assembly further includes a second magnetic field sensor coupled to the second portion. The rolled section is shaped such that the second magnetic field sensor is oriented with respect to the first magnetic field sensor so that the second magnetic field sensor has a primary sensing direction aligned with an axis orthogonal to the longitudinal axis.
