Artificial heart ready for human trials.
French company CARMAT have announced that their artificial heart is scheduled to be implanted into patients in four medical centers around the world. The device completely replaces the patient’s original heart.
The artificial heart consists of two cavities, mimicking the organ’s ventricles, which are separated by a moving membrane that’s hydraulically powered via a special actioning fluid. This membrane reproduces the action of the ventricular wall during contractions, creating blood flow in and out of the device. The system is works in conjunctions with sensors and a microcontroller that continuously adjust the activity of the prosthesis to match the needs of the patient.

Trilobite Phacops rana
by *NocturnalSeaThe “classic trilobite” Phacops rana — the state fossil of Pennsylvania.
Surrounding this swarm are other common fossils of Pennsylvania:
- the gastropods Worthenia and Strobeus,
- the brachiopod Acrospirifer
- the bivalve Leiopteria.
- and a couple of speculative sea slugs.
Many of the colors and designs of this piece were based on New England tide pools.
- The Leiopteria, for example, are colored and clumped like Mytilis edulis, the common blue mussel of the Northern Atlantic.
- Additionally, the pink-gray background is a crustose coralline algae similar to the “bubble gum crust” Phymatolithon lenormandii which is common on intertidal rocks in New England. (Coralline algae possess a “skeleton” of calcium carbonate.)
- The dark purple seaweed along the edge is meant to resemble Chondrus crispus, a red algae that possess a blue iridescence when underwater.
- The small yellow creatures in the bottom left are trilobite larvae called protaspids. Little more than head-shields at this point, the protaspids will grow new body segments with each molt.
