Abstract

An occlusive device for occluding a target area can include an elongate member having opposing first and second side edges extending longitudinally along the member and a member width. The member can have a collapsed configuration in which the first and second side edges are curled toward each other about a longitudinal axis of the member. Further the member can have an expanded configuration in which the member form a series of loops and the first and second side edges uncurl to be spaced apart from each other.

Claims18

Dependent claims

An occlusive device for occluding an aneurysm, comprising:

an elongate member formed of a single layer sheet of mesh material having a longitudinal axis, opposing first and second side edges extending longitudinally along the member, and a body extending laterally between the first and second side edges, wherein the member has:
(a) a collapsed configuration for delivery through a catheter to the aneurysm, wherein, in the collapsed configuration, the member is rolled about a line parallel to the longitudinal axis of the member such that the first side edge is positioned within an inner portion of the member, the second side edge is positioned at an outer portion of the member that radially overlaps the inner portion, and the body is radially between the first side edge and the second side edge such that the second side edge is between the body and an interior surface of the catheter;
and (b) an expanded configuration for positioning within an aneurysm and in which the member forms a predetermined three-dimensional shape.

Dependencies are inferred from the claim text.
