Abstract: Artificial muscle device and method of manufacturing the same for the treatment or control of an organ such as the heart. The artificial muscle device comprises artificial polymer actuators or fibers that can work together to form the artificial muscle structure. The artificial fibers are electrothermally active contractile polymers capable of various characteristics, including increased contractile forces. The artificial actuators are knittable or weavable into patterns and shapes to create unique artificial muscles that can be shaped into implantable devices.

Abstract: An implantable device and methods for preparing and implanting said device into a subject for use in treating a medical condition when implanted therein is disclosed. The device comprises at least one coaxial fibre of a hydrophilic polymer and a hydrophobic polymer, wherein at least one of said polymers is loaded with an agent that is active towards treating the medical condition.
