Vascular Occlusion device of Double Cone of nitinol (DCN) for closure of patent ductus arteriosus Persistence

摘要

The vascular Occlusion of Double Cone device of the present Invention is a Double Spiral coils in a Double Cone shape and the other preferably with Polyester Fibre along its length.Where the minor diameter of the spiral Double Cone is in the center of the device (Figure 1) to enable the formation of a thrombus and prevent blood flow through the DAP once implanted the device. The device is preferably made with nitinol, Alea Of nickel and Titanium for wide use in the Medical Industry.Nitinol is commonly known as the engineering material in the Medical Industry thanks to its Elastic Properties and shape memory that allows the Devices made from this material can be remote Anatomical sites through catheters or other systems Introduction.The main differences with previous devices are, firstly, that the present Invention is a single piece of Double Cone made of nitinol; secondly, PSF can be added between the Rings of a Spiral.Polyester fibres with the same function of Latex Balloon of the CCD to generate the thrombus and prevent blood flow through the PDA. The device of Double Cone (DCN) of the present Invention completely occludes The Dap without leaving residual Short Circuit and helps the epite Since the end of the ductus.So far No data reported hemolysis produced with devices manufactured with nitinol.
