Abstract
A medical implant device can comprise a light source and a light sensor, and a housing configured to receive the light source and the light sensor. The housing can comprise a first wall portion configured to be positioned over an extraluminal surface of a coronary sinus, the first wall portion comprising a first surface oriented toward the extraluminal surface. A first light-transparent region of the first wall portion can be configured to allow passage therethrough of an emitted light signal from the light source into the coronary sinus, and a second light-transparent region of the first wall portion can be configured to allow passage therethrough of a reflected light signal from within the coronary sinus for detection by the light sensor.

A medical implant device, comprising:
- a light source and a light sensor;
- and
- a housing configured to receive the light source and the light sensor, the housing comprising:
- a first wall portion configured to be positioned over an extraluminal surface of a coronary sinus, the first wall portion comprising a first surface oriented toward the extraluminal surface,
- a first light-transparent region of the first wall portion configured to allow passage therethrough of an emitted light signal from the light source into the coronary sinus, and
- a second light-transparent region of the first wall portion configured to allow passage therethrough of a reflected light signal from within the coronary sinus for detection by the light sensor.
A medical implant device, comprising:
- a light source and a light sensor;
- and
- a housing configured to receive the light source and the light sensor, the housing comprising:
- a first wall portion configured to be positioned over a surface of a first atrial wall portion adjacent to a coronary sinus wall portion, the surface of the atrial wall portion being oriented toward a left atrium, and the first wall portion comprising a first surface oriented toward the surface of the atrial wall portion,
- a first light-transparent region on the first wall portion to allow passage therethrough of an emitted light signal from the light source, and
- a second light-transparent region on the first wall portion to allow passage therethrough of a reflected light signal from the coronary sinus for detection by the light sensor.
A medical implant device, comprising:
- a light source and a light sensor;
- a first magnetic component;
- a housing coupled to the first magnetic component, and configured to receive the light source and the light sensor, the housing comprising:
- a first wall portion configured to be positioned over an extraluminal surface of a coronary sinus, the first wall portion comprising a first surface oriented toward the extraluminal surface,
- a first light-transparent region on the first wall portion to allow passage therethrough of an emitted light signal from the light source, and
- a second light-transparent region on the first wall portion to allow passage therethrough of a reflected light signal from the coronary sinus for detection by the light sensor;
- and
- a second magnetic component configured to be positioned within the coronary sinus to be aligned with and magnetically couple to the first magnetic component through a coronary sinus wall portion to position the first light-transparent region and the second light-transparent region over the extraluminal surface of the coronary sinus
