IMPLANTABLE OPTICAL HEMODYNAMIC SENSOR INCLUDING LIGHT TRANSMISSION MEMBER
First Claim
1. An implantable medical system comprising:
- an implantable housing;
a light transmission member extending from the housing;
an optical emitter coupled to the housing; and
a detector coupled to the housing, wherein the detector is configured to generate a signal indicative of an intensity of light emitted by the optical emitter and transmitted to the detector,wherein at least one of the optical emitter or the detector are optically coupled to the light transmission member.

Abstract
An implantable medical device (IMD) includes an optical hemodynamic sensor comprising at least one optical emitter and at least one detector. In some examples, the at least one optical emitter may be optically coupled to at least one light transmission member that extends from a housing of the IMD. In addition, in some examples, the at least one detector may be optically coupled to at least one light transmission member that extends from the housing of the IMD. In other examples, an optical emitter and/or detector of a hemodynamic sensor may be carried by an extension member that extends from a housing of the IMD. The elongated member may electrically couple the optical emitter and/or detector to a controller or other components within the IMD housing.
