Intraluminal occlusion devices and methods of blocking the entry of fluid into bodily passages

摘要

An intraluminal occlusion device includes a frame and an attached covering. The frame includes longitudinal struts having concave and convex portions. The intraluminal occlusion devices can be implanted at an opening to a body vessel, such as a blind passage, to block the entry of fluid into the vessel. Methods of blocking the entry of fluid into bodily passages are also described.

主权项

1. An intraluminal occlusion device having a longitudinal axis, comprising: a tubular frame having a proximal end defining a proximal opening, a distal end defining a distal opening, and a circumferential surface extending from the proximal end to the distal end, the frame comprising two or more longitudinal struts and a plurality of interconnecting struts extending between adjacent longitudinal struts, each of the longitudinal struts having a proximal concave portion and a distal convex portion disposed within a plane that includes said longitudinal axis; and a covering extending over the proximal opening and attached to the tubular frame; wherein a first longitudinal strut has a first proximal concave portion and a first distal convex portion;
wherein the first proximal concave portion has a first longitudinal midpoint and the first distal convex portion has a second longitudinal midpoint; wherein a first transverse axis orthogonally intersects the first proximal concave portion at the first longitudinal midpoint; wherein a second transverse axis orthogonally intersects the first distal convex portion at the second longitudinal midpoint; wherein the first transverse axis orthogonally intersects said longitudinal axis of said intraluminal occlusion device; and wherein the second transverse axis non-orthogonally intersects said longitudinal axis of said intraluminal occlusion device.
