Intravascular implants and methods of using the same

摘要

An intravascular implant and methods of using the implant within the vasculature of the body, for example near a vascular aneurysm, are disclosed. The method of attaching a second implant, such as a vascular graft, to the intravascular implant is also disclosed. The implant can be made from an anchor, a connector and a seal.

主权项

1. An intravascular implant system comprising:
an anchor configured to affix the intravascular implant system to a vascular site, wherein the anchor comprises a helical anchor coil; a seal comprising a seal ring and a graft having a cylindrical length coupled to the seal ring; and four crossing pairs of connector wires connecting the seal with the helical anchor coil comprising a connector first end and a connector second end of cacti of the four crossing pairs of connector wires, wherein the connector second end of each of the four crossing pairs of connector wires is attached to two connection endpoints on a circumferential length of the seal and the connector first end of each of the four crossing pairs of connector wires is attached to two connection endpoints on a circumferential length of the helical anchor coil, wherein adjacent connector first ends are separated by a circumferential length of the helical anchor coil, and wherein the four crossing pairs of connector wires define four hexagonal transverse flow ports of the intravascular implant system including a first hexagonal transverse flow port and a second hexagonal transverse flow port and the circumferential length of the seal ring defines a side of one of the four hexagonal transverse flow ports, and wherein the first hexagonal transverse flow port is diametrically opposite the second hexagonal transverse flow port.
