METHOD AND DEVICE FOR ANEURYSM REPAIR USING INTRAOPERATIVE ENDOLUMINAL COUPLING TO PRE-IMPLANTED STENT FOR DUAL BARRIER FORMATION

The present invention consists of a flow diverter device deployed in the aneurysm neck to be used during an endovascular intervention. The device consists of a single filament that forms two spirals: the distal spiral (on the aneurysmal side) and the proximal spiral (on the vascular face of the stent). These spirals are continuous with a central spring that connects them. The spring passes through a predefined cell of a previously implanted stent. The distal and proximal barriers act as flow diverters. They cover a specific group of stent cells in front of the aneurysm neck. The intermediate spring traverses a stent cell, preventing movement. The two barriers, along with the connecting spring, play a crucial role in blocking any dislodgment after deployment. This invention combines precise positioning, flow diversion, and stability to address aneurysms effectively, avoiding direct manipulation of the lesion and respecting the parent vessel.
