A mere $40K gets you Syndaver's full-body practice cadaver, a beautifully detailed surgical simulator, with "skin with fat and fascia planes, every bone, muscle, tendon, and ligament in the body, fully articulating joints, a functioning respiratory system including trachea, lungs, and diaphragm, a complete digestive tract from the esophagus to rectum, the urinary tract (kidneys, bladder, and urethra), visceral organs (liver, gall bladder, pancreas, spleen), reproductive organs, a circulatory system with heart and coronary arteries, aorta, vena cava, and the primary arterial and venous trunks leading to the extremities."
They call it "pinnacle of hands-on surgical simulation" and "a 3D jigsaw puzzle" -- and who am I to argue. If $40K is too rich for your synthetic blood, they also do organs, wearable simulators for training roleplay, synthetic tissues, and a whole range of delightful wobbly bits.
The model pumps heated synthetic blood (pulsed flow away from the heart and drainage toward the heart), is capable of insufflation, and can be intubated and ventilated. Individual tissues of construction have been validated by SynDaver™ Labs over the last decade to mimic the mechanical and physico-chemical properties of the relevant living tissue.
Additional soft tissues included but not shown include full-body fascia, subcutaneous fat, and skin. ALL muscles, bones, organs, and vascular components are separately removable and replaceable to allow onsite servicing and upgrades.
The model may be covered with either the standard SynDaver™ synthetic human (pure wet chemistry) skin or our new organosilicate-synthetic human hybrid (polymer outer - wet inner) skin.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
