Abstract

The disclosure of the present application provides devices, systems, and methods for the prevention of stroke. In at least one embodiment of a device of the present application, the device comprises an extension portion sized and shaped to fit within an artery extending from an aortic arch, and a flange portion sized and shaped to prevent the device from advancing into the artery extending from the aortic arch in which the device may be positioned. In at least one embodiment of a system for preventing stroke of the present application, the system comprises a hypotube, a folder coupled to a distal end of the hypotube, a sleeve positioned circumferentially around the hypotube proximal to the folder, and a stent, wherein a first part of the stent may be positioned within the folder, and wherein a second part of the stent may be positioned within the sleeve.

Claims26

Dependent claims

A device for the prevention of stroke, the device comprising:

an extension portion sized and shaped to fit within an artery extending from an aortic arch and comprising a proximal end and a distal end;
and
an expandable, non-bulbous, annular flange portion coupled with the proximal end of the extension portion, the flange portion comprising an inner diameter and sized and shaped to prevent the device from advancing into an artery extending from the aortic arch in which the device may be positioned, the flange portion consisting essentially of a perimeter, an opening, and two or more parallel convex struts and no other struts, the two or more parallel convex struts each comprising an exterior surface and extending from the flange portion across the opening, and wherein the two or more parallel convex struts are spaced apart from each other to define unbroken parallel apertures that span the opening, configured to protrude into a path of blood flow within a vasculature adjacent to the artery, and capable of diverting an embolus within the path of blood flow within the vasculature from entering the artery when the device is positioned within the artery;
wherein the flange portion does not define any apertures within the opening other than the parallel apertures, and the perimeter surrounds the two or more convex struts and, when expanded, further comprises an outer diameter that is larger than the inner diameter;
and
wherein no part of the exterior surfaces of the two or more parallel convex struts comprises a concave shape.

A device for the prevention of stroke, the device comprising:

an extension portion comprising a substantially cylindrical shape, the extension portion sized and shaped to fit within an artery extending from an aortic arch and comprising a proximal end and a distal end;
an expandable, non-bulbous, annular flange portion coupled with the proximal end of the extension portion, the annular flange portion comprising an inner diameter and sized and shaped to prevent the device from advancing into an artery extending from the aortic arch in which the device may be positioned, the flange portion consisting essentially of a continuous perimeter, an opening, and two or more parallel convex struts each comprising an exterior surface and extending from the annular flange portion across the opening, and wherein the two or more parallel convex struts are spaced apart from each other to define unbroken parallel apertures that span the opening, configured to protrude into a path of blood flow within a vasculature adjacent to the artery, and capable of diverting an embolus within the path of blood flow within the vasculature from entering the artery when the device is positioned within the artery;
and
one or more radiopaque markers positioned upon the flange portion, wherein when the device is positioned within the artery extending from an aortic arch, the one or more radiopaque markers facilitate alignment of the device, the alignment selected from the group consisting of an alignment so that the two or more parallel convex struts are positioned approximately perpendicular to a direction of blood flow within the aortic arch and an alignment so that the two or more parallel convex struts are positioned in a direction of blood flow within the aortic arch;
wherein the flange portion does not define any apertures within the opening other than the parallel apertures, and the perimeter surrounds the two or more parallel convex struts and, when expanded, further comprises an outer diameter that is larger than the inner diameter;
and
wherein no part of the exterior surfaces of the two or more parallel convex struts comprises a concave shape.

and
a non-bulbous flange portion coupled with the proximal end of the extension portion, the flange portion comprising an expandable, annular positioning portion sized and shaped to prevent the device from advancing into an artery extending from the aortic arch in which the device may be positioned, the annular positioning portion comprising an inner diameter and a convex diverting portion consisting essentially of an opening and two or more parallel convex struts and no other struts, the two or more parallel convex struts each comprising an exterior surface and extending from the annular positioning portion across the opening, and wherein the two or more parallel convex struts are spaced apart from each other to define unbroken parallel apertures that span the opening, configured to protrude into a path of blood flow within a vasculature adjacent to the artery, and capable of diverting an embolus within the path of blood flow within the vasculature from entering the artery when the device is positioned within the artery;
wherein the diverting portion does not define any apertures within the opening other than the parallel apertures and the perimeter of the positioning portion surrounds the two or more parallel convex struts and, when expanded, further comprises an outer diameter that is larger than the inner diameter;
and
wherein no part of the exterior surfaces of the two or more parallel convex struts comprises a concave shape.
