Embodiments herein relate to body vibration analysis systems and methods. In an embodiment, a body vibration analysis system is included having a first light source configured to illuminate a surface of the body from a first angle with a first set of lighted features and a second light source configured to illuminate a surface of the body from a second angle with a second set of lighted features, wherein the second set of lighted features are optically distinguishable from the first set of lighted features. The system further includes a camera configured to detect light reflected from the surface of the body and a control circuit configured to receive an input from the camera and assess spatial vibration as a function of location on the surface of the body. Other embodiments are also included herein.

Body vibration analysis systems and methods

Embodiments of the invention are related to medical devices filled with a liquid composition, amongst other things. In an embodiment, the invention includes a hermetically sealed housing defining an interior volume, a component module disposed within the interior volume, the component module comprising a circuit board, the component module displacing a portion of the interior volume. A liquid composition can be disposed within the housing, the liquid composition filling at least 80% of the interior volume not displaced by the component module. Other embodiments are also included herein.

Medical device with convertible solid

An implantable pulse generator includes a device housing containing pulse generator circuitry and a header molded to the device housing. The header can be formed of an epoxy header material. A header component can have a first part molded in the header material to fix the header component to the header at a surface of the header and a second part extending out of the header material.

This document describes an apparatus or an implantable medical device including an implantably biocompatible case. The apparatus can include a component that can be sealed within the case. The apparatus can include a vibration isolator and an at least a portion of the vibration isolator can be situated between and compressively preloaded to bias against the case and the component.

Pre-loaded vibration isolator for implantable device

An apparatus comprises an implantable sensor and a signal analyzer circuit communicatively coupled to the implantable sensor. The implantable sensor is configured for coupling to an implantable lead and the implantable sensor provides an electrical vibration sensor signal representative of mechanical vibration of the implantable lead. The signal analyzer circuit is configured to determine a baseline of the vibration sensor signal, detect a change in the vibration sensor signal from the baseline vibration sensor signal, and provide an indication of the change to a user or process.

Method and apparatus for sensing mechanical energy of an implantable lead

An implantable medical device comprising a housing and a limiting structure defining a resonant region in the housing. An acoustic transducer is connected to the limiting structure and extends into the resonant region so that the resonant region mechanically amplifies the deformation of the acoustic transducer at a resonant frequency. An implantable medical device comprising a housing and a limiting structure defining a resonant region in the housing. An acoustic transducer having the shape of a beam is mechanically coupled to the limiting structure and partially extends into the resonant region so that the resonant region mechanically amplifies the deformation of the acoustic transducer at a resonant frequency. An implantable medical device comprising a housing, an acoustic transducer coupled to the housing, and a means for mechanically amplifying the deformation of the acoustic transducer at a resonant frequency. The means defines a resonant region in the housing.
