Title:
ELECTROMAGETIC SYSTEM FOR RAPID CANNULATION OF FENESTRATED ENDOVASCULAR GRAFTS
Document Type and Number:
WIPO Patent Application WO/2019/139898
Kind Code:
A1
Abstract:
Disclosed are implantable tubular devices having a fenestration in a wall of the tubular device and a conductive coil positioned around the fenestration, such that the coil is operable to generate a magnetic field when electrical current flows through the coil. The magnetic field can be used to draw a ferrous or magnetically tipped guidewire or other device to and through the fenestration. In the example of a fenestrated endovascular graft, the coil can be used to draw a guidewire out through a fenestration into a branch blood vessel, such that the guidewire can be used to deliver a branch of the graft through the fenestration into the branch vessel. A power source can be contained in a nosecone.
