Abstract

An endovascular fixation device includes a first portion and a second portion connected to the first portion to define a central lumen extending longitudinally through the portions. The first portion includes a first radially expandable ring and at least one first connector, connected to the first ring, configured to cause at least one first flarable crown of the first ring to flare radially outwardly relative to other portions of the first ring when the first ring is expanded from a retracted position to an expanded position. The second portion includes a second radially expandable ring and at least one second connector, connected to the second ring, configured to cause at least one second flarable crown of the second ring to flare radially outwardly relative to other portions of the second ring when the second ring is expanded from a retracted position to an expanded position.

A medical device, comprising:

a first radially expandable ring including a plurality of first flarable crowns distributed about a circumference of the first ring, each of the first flarable crowns being configured to flare radially outwardly so that a first end of each of the first flarable crowns bends further radially outward than a second end of each of the first flarable crowns when the first ring is expanded from a retracted position to an expanded position;
a second radially expandable ring including plurality of second flarable crowns distributed about a circumference of the second ring, each of the second flarable crowns being configured to flare radially outwardly so that a first end of each of the second flarable crowns bends further radially outward than a second end of each of the second flarable crowns when the second ring is expanded from a retracted position to an expanded position;
and
a plurality of struts connecting the second ends of at least a portion of the first flarable crowns to the second ends of a corresponding portion of the second flarable crowns.
