Abstract

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.

Claims

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.

2. The system of claim 1, wherein the seal has an expanded configuration, and wherein the anchor has an expanded configuration, and wherein the outer diameter of the seal in the expanded configuration is approximately equal to the outer diameter of the anchor in the expanded configuration.

3. The system of claim 1, Wherein the seal has a first conduit and a second conduit, and wherein a portion of the first conduit and of portion of the second conduit is located in between the seal ring and another seal ring.

4. The system of claim 1, wherein the seal is configured to be deployed adjacent to a vascular aneurysm.

5. The system of claim 1, wherein the seal has an inflatable volume.

6. The system of claim 1, wherein the seal is located inferior relative to the anchor.

7. The system of claim 1, wherein the seal comprises a solid seal volume.

8. The system of claim 1, wherein the seal comprises a biodegradable polymer.
