IMPLANTABLE OPTICAL HEMODYNAMIC SENSOR INCLUDING AN EXTENSION MEMBER
First Claim
1. An implantable medical system comprising:
- an implantable housing;
an extension member extending from the housing;
an optical emitter that emits light; and
a detector that generates a signal indicative of an intensity of light emitted by the optical emitter and transmitted to the detector, the signal indicating a hemodynamic characteristic of a patient,wherein at least one of the optical emitter or the detector are carried by the extension member.

Abstract
An implantable medical device 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 medical device. 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 medical device. In other examples, an optical emitter and/or detector of a hemodynamic sensor may be carried by an elongated 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.
