Inventors turn to mechanical means for heart innovation; new coatings prolong implant life
This article was originally published in Clinica
Novel biomaterials were evident amongst December’s list of patent applications, with examples of new composites for orthopaedic use. These include silica zeolite/hydroxyapatite combinations and materials that can promote growth of multiple tissue types. In addition, material science was the key element of a patent application covering a potentially new method for growing cells that could have a major impact on many areas of tissue engineering. In cardiovascular medicine, there were some interesting inventions based on more traditional mechanical methods, as opposed to biological/material methods that seem to have dominated this area of medicine over the past few years. These cardiovascular patent applications include an atherectomy device that takes advantage of centripetal forces to provide a larger cutting diameter in the vessel.

UK engineering firm Dyson, best known for its vacuum cleaners, fans and hand driers, plans to make 10,000 specially designed ventilators under a UK government contract.
Production of ventilators is up by tens of thousands of units across Europe, but the supply chain is likely to come under strain with further expansion.
The proceeds from the investment will enable Nyxoah to prepare for the IDE pivotal trial of the Genio system in the US, and accelerate market access and commercialization activities in Europe, Australia and New Zealand.
