Abstract: An optical sensor for a medical device includes a fixed lens spacing between emit and receive modules to achieve target sensor sensitivity, while varying other sensor parameters in order to increase signal amplitude without increasing power demand. An optical sensor connected to a housing of a medical device includes a circuit board, an opto-electronic component, a wall, a lens, and a ferrule. The circuit board is arranged within the housing. The opto-electronic component is mounted on a surface of the circuit board. The wall protrudes from the surface of the circuit board and surrounds the opto-electronic component. The lens is offset from the surface of the circuit board. The ferrule is connected to the housing, the lens and the wall. An inner surface of the wall mates with an outer surface of the ferrule.

Abstract: An optical sensor for a medical device includes a fixed lens spacing between emit and receive modules to achieve target sensor sensitivity, while varying other sensor parameters in order to increase signal amplitude without increasing power demand. The arrangement of an opto-electronic component within an optical sensor receive module is improved by masking the receive module lens with an opaque member to create a masked lens leading edge that is aligned with a leading edge of the opto-electronic component.

Abstract: An optical sensor for a medical device includes a fixed lens spacing between emit and receive modules to achieve target sensor sensitivity, while varying other sensor parameters in order to increase signal amplitude without increasing power demand. The size of at least one of emit and receive module lenses of an optical sensor, and the offset between the opto-electronic component and the respective lens of at least one of emit and receive modules is decreased to increase amplitude of the signal received by the receive module from the emit module.

Abstract: An implantable optical sensor and associated manufacturing method include a sensor housing having an inner surface and an outer surface and a window formed in the housing extending between the housing inner surface and the housing outer surface. An opto-electronic device enclosed within the housing and having a photonic surface is operatively positioned proximate the window for emitting light through the window or detecting light through the window. An optical coupling member is positioned between the opto-electronic device and the window for reducing light reflection at a surface within the implantable optical sensor.

Abstract: An implantable medical device having an optical sensor selects the function of modular opto-electronic assemblies included in the optical sensor. Each assembly is provided with at least one light emitting device and at least one light detecting device. A device controller coupled to the optical sensor controls the function of each the assemblies. The controller executes a sensor performance test and selects at least one of the plurality of assemblies to operate as a light emitting assembly in response to a result of the performance test. The controller selects at least one other of the plurality of optical sensor assemblies to operate as a light detecting assembly in response to a result of the performance test.

Abstract: An implantable medical device is manufactured with a hermetically sealed housing and a modular assembly enclosed within the housing. The modular assembly includes a circuit board, an electronic component mounted on a top surface of the circuit board, and a wall formed having an outer surface and an inner surface separated by a top edge and a bottom edge, the wall bottom edge positioned against the circuit board such that the wall encircles the electronic component coupled to the circuit board. The wall top edge is coupled to the housing a ferrule in one embodiment.
