The Hybrid Heart consortium envisions to develop and bring to the clinic soft biocompatible artificial organs. These will consist of a soft robotics shell with actuators (‘artificial muscles’) and sensors, enabling completely natural motion. The inner lining and structures will be made by in situ tissue engineering (TE), ensuring biocompatibility of blood-contacting surfaces.
As the first step, the consortium will develop the Hybrid Heart, which can completely replace a patient’s heart in a procedure similar to a heart transplant, to provide a cure for heart failure, which affects ~23 million people worldwide. Currently, patients with end-stage heart failure either receive a heart transplant, if available, or long-term mechanical circulatory support, which causes severe complications.
To achieve the ambitious goal of providing a permanent cure for these patients, the participants will, in parallel, develop the components of the Hybrid Heart: 1) a soft elastomeric robotics shell containing actuators and sensors, 2) scaffolds for in situ TE of inner lining, valves and vessels and 3) a wireless energy transfer system. These components together will form the full Hybrid Heart, which will be soft, adaptable, wireless and fully bio- and emo-compatible. Both functionality as well as biocompatibility of the HybridHeart will be shown in a Proof-of-Principle study in the chronic sheep model at the end of the project.
The Hybrid Heart project will be carried out by an interdisciplinary group of (academic) researchers and high-tech SMEs, with experience in cardiac surgery, TE, soft robotics and engineering. The technology underlying the Hybrid Heart is applicable to a range of soft robotics-based artificial organs, including the bowel, lung, or muscle structures (limbs). Replacing an entire organ with bioinspired robotic elements, TE biocompatible surfaces, artificial sensors, and an external power source allows for an off-the-shelf therapy for patients with organ failure.
