In an example embodiment, an optical communication system includes an implantable optical transmitter and an external optical receiver. The transmitter includes a housing having one or more drivers, plural light emitting sources, and an optical element arranged therein. Each driver converts a digital data signal into modulation signals to drive the sources. Each source generates a light beam in response to a corresponding modulation signal, each light beam contributing to form a single optical signal. The optical element directs the light beams to exit the housing such that a peak position of light intensity of each light beam is separated from a corresponding peak position of light intensity of an adjacent light beam by at least a first distance and less than a second distance. The optical receiver includes at least one photodiode that detects light generated by the sources and generates a reconstructed data signal.

Optical transmission for an implantable system

A blood filter device having occlusion-resistant characteristics. The occlusion-resistant characteristics decrease the likelihood of the filter being blocked by thrombi. The filter device includes at least one anchor portion for anchoring the filter device within one or more arteries, and a filter portion for filtering thrombi from the blood entering the artery. In some embodiments, an anchor portion is capped with a filter cap. In various embodiments, the filter cap is protrudes into the aorta to promote occlusion resistance. In one embodiment, the device can be modified in situ to re-establish normal blood flow through the artery in the unlikely case of thrombotic or other blockage of the filter. In some embodiments, a bypass opening or open channel defining an access port is provided to accommodate passage of surgical instruments into the artery and to enable blood flow to bypass the filter should the filter become heavily occluded.
