ETH researchers develop silicone heart that beats almost like a human heart (Video)

silicone heart

ETH researchers from the Functional Materials Laboratory have developed a silicone heart that beats almost like a human heart. In collaboration with colleagues from the Product Development Group Zurich, they have tested how well it works.

It looks like a real heart. And this is the goal of the first entirely soft artificial heart: to mimic its natural model as closely as possible. The silicone heart has been developed by Nicholas Cohrs, a doctoral student in the group led by Wendelin Stark, Professor of Functional Materials Engineering at ETH Zurich. The reasoning why nature should be used as a model is clear. Currently used blood pumps have many disadvantages: their mechanical parts are susceptible to complications while the patient lacks a physiological pulse, which is assumed to have some consequences for the patient.

‘Bio-3D printer’- based system to create vascular prosthetics (Video)

Small caliber vascular prostheses are not clinically available because synthetic vascular prostheses lack endothelial cells which modulate platelet activation, leukocyte adhesion, thrombosis, and the regulation of vasomotor tone by the production of vasoactive substances. We developed a novel method to create scaffold-free tubular tissue from multicellular spheroids (MCS) using a “Bio-3D printer”-based system. This system enables the creation of pre-designed three-dimensional structures using a computer controlled robotics system. With this system, we created a tubular structure and studied its biological features. Continue reading “‘Bio-3D printer’- based system to create vascular prosthetics (Video)”

Flexy-Hand 2 – Filaflex Remix: 3D Printed Prosthetic Hand Looks and Moves Like the Real Thing

Most of the 3D printed prosthetic hands stories have come our way from various e-NABLE members. e-NABLE is a group of over 3,000 volunteers who share ideas and designs on 3D printable prosthetic devices, and then connect with other individuals in need of these devices., in order to 3D print them a new hand, arm, or whatever other extremity they may need.

The promise of medical 3D printing: from 3D printed prosthetics to regenerated human limbs

Considering the high pricing of prosthetics and the difficulty of customizing them, 3D printing provides a much-anticipated solution to the artificial limb market. MIT developed a solution called FitSocket. It uses 3D Scanning and 3D printing to make artificial limbs that are fully customizable, to the finest detail. Continue reading “The promise of medical 3D printing: from 3D printed prosthetics to regenerated human limbs”

YouBionic – The 3D Printed Robotic Controlled Prosthetic Hand is One Step Closer to Reality

Back in July, we covered a company called YouBionic, who was looking to create a 3D printed bionic, Arduino-controlled prosthetic hand. At that time they were still working on the design as well as the mechanism to drive the hand’s movements. Today, however, we get word from the company that they have finished their first prototype of this hand.
