REMOTELY ADJUSTABLE PROSTHETIC RING FOR MITRAL AND TRICUSPID VALVE REPAIR

摘要

Remotely adjustable prosthetic ring for mitral and tricuspid valve repair, which consists of a ring of biocompatible material composed of three elements: a tubular element of rigid material (1), a further element of semi-rigid material (2) that slides via either of its ends or via both simultaneously inside the first element, and a further element consisting of a device provided with an energy source (4), capable of receiving and translating orders from an external unit with a view to sliding the semi-rigid element of the ring in a controlled manner inside the rigid tubular element, by means of an opening, closure and fastening system, it being possible, once surgery has been completed, to reduce or to increase its perimeter length and therefore its cross-section area.
