1. An expandable device for delivery to a target location in a body vessel, comprising:
- a body comprising first and second elongate members coupled together at proximal, medial, and distal locations of the body, the body having a proximal end, freely movable relative to a distal end thereof, wherein;
the first elongate member comprises (i) a first portion extending along an arcuate path from the proximal location in a clockwise circumferential direction until arriving at the medial location, (ii) a second portion extending along an arcuate path from the medial location in a counterclockwise circumferential direction until arriving at the distal location, and (iii) a third portion, disposed at the medial location, interconnecting the first and second portions; and
the second elongate member comprises (i) a first portion extending along an arcuate path from the proximal location in a counterclockwise circumferential direction until arriving at the medial location, (ii) a second portion extending along an arcuate path from the medial location in a clockwise circumferential direction until arriving at the distal location, and (iii) a third portion, disposed at the medial location, interconnecting the first and second portions,wherein the first elongate member third portion is coupled to the second elongate member third portion to interconnect the first and second members, and wherein the first and second portions of the first and second members are spaced apart from each other to collectively define a frame having a central lumen extending therethrough;
wherein the first portions of the first and second elongate members collectively define a first support element having a first maximum expanded diameter, and the second portions of the first and second elongate members collectively define a second support element having a second maximum expanded diameter different from the first maximum expanded diameter.

Abstract
An implant may include a frame and a cover to facilitate endoluminal vessel occlusion, selective release of embolic material toward a target region, and/or endoluminal stenting. The frame of the implant provides radial expansion properties to secure the cover within a body vessel. The cover and/or the frame can occlude flow of a fluid through the body vessel.

22. An expandable device for delivery to a target location in a body vessel, the device comprising:
-
first and second elongate members being coupled together at proximal, medial, and distal locations and forming first and second hoop elements, the first and second hoop elements being longitudinally spaced apart from each other to collectively define a frame having a central lumen extending therethrough, the first and second hoop elements having different maximum expanded diameters; wherein the first elongate member extends arcuately from the proximal location in a clockwise circumferential direction until arriving at the medial location and the second elongate member extends arcuately from the proximal location in a counterclockwise circumferential direction until arriving at the medial location to form the first hoop element; and wherein the first elongate member extends arcuately from the medial location in a counterclockwise circumferential direction until arriving at the distal location and the second elongate member extends arcuately from the medial location in a clockwise circumferential direction until arriving at the distal location to form the first hoop element to form the second hoop element. - View Dependent Claims (23, 24, 25, 26)
