Describes a novel engineering concept for a modular TAVI prosthesis designed to reduce the delivery catheter profile and potentially decrease vascular complications.
Transcatheter aortic valve implantation (TAVI) is a relatively new medical intervention. Research on dedicated TAVI devices is an exciting and dynamic field to be explored by professionals involved in technological innovation. The authors describe in this article the first engineering concept and part of the US Patent of a new valve prosthesis. Divided into two pieces to be separately implanted using a single catheter by means of an innovative technique, this device aims at reducing prosthesis and delivery catheter profile. Miniaturization of the valve and delivery system is probably the best solution to reduce the morbidity and mortality that derive from vascular complications associated with TAVI.
