Abstract: Implantable medical devices including a housing that contains operational circuitry for the implantable medical device and a dispensed hydrogen getter. The hydrogen getter may include a getter carrier material and one or more getter materials carried as suspensions in the getter carrier material, with the getter materials taking the form of organic compounds, such as fatty acids, or powdered metal oxides, or combinations thereof. The hydrogen getter may instead be comprised of two fatty acids having different melt temperatures. The hydrogen getter may be dispensed onto an encapsulant layer or other component of the implantable medical device, or may be blended into an encapsulant layer.

Abstract: Implantable medical devices are constructed with a dampening layer to limit motion of components inside a housing of the implantable medical devices. The dampening layer may have features to provide thermal isolation for certain components. The dampening layer may have features to allow mechanical vibration of selected components. The dampening layer may have features to ensure an air space exists to enable a residual gas analysis test.

Abstract: The present disclosure provides to encapsulate the distal components of a scope to form a distal cap assembly, which removes the need for adhesives and potting often used in conventional distal cap assemblies. In particular, the present disclosure provides a spline structure configured to hold the distal end components in a predefined arrangement. The spline structure, along with the distal end components, is inserted into a mold and the spline structure along with the distal end components is encapsulated (e.g., in a polymer using hot melt, or the like) to form a distal cap. The distal cap locks the distal end components into the spline structure and protects the distal end components from moisture and relative movement. As a benefit, the present encapsulation techniques and distal cap assembly is faster to manufacture and provides less room for error than conventional methods.
