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.
Claims21
An expandable device for delivery to a target location in a body vessel, comprising:
- a first elongate member having (i) a first portion extending along an arcuate path in a clockwise circumferential direction, (ii) a second portion extending along an arcuate path in a counterclockwise circumferential direction, and (iii) a third portion interconnecting the first and second portions;
- and
- a second elongate member coupled to the first elongate member, the second member having (i) a first portion extending along an arcuate path in a counterclockwise circumferential direction, (ii) a second portion extending along an arcuate path in a clockwise circumferential direction, and (iii) a third portion interconnecting the first and second portions,
- wherein the first member third portion is coupled to the second 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.
An expandable device for delivery to a target location in a body vessel, comprising:
- first, second, and third support elements, each comprising at least one wire extending in a circumferential direction to form a loop, each of the support elements extending generally orthogonally relative to a longitudinal axis of the device when the device is in a relaxed state;
- a first axial element interconnecting the first and second support elements at a first circumferential position;
- and
- a second axial element interconnecting the second and third support elements at a second circumferential position, offset from the first circumferential position by about 180′;
- wherein the first, second, and third support elements are resiliently biased to the relaxed state from a collapsed state in which the device extends in a substantially linear configuration.
An expandable device for delivery to a target location in a body vessel, comprising an elongate helical member extending in a helical path and having a cross-sectional shape in which an axial width is less than a radial thickness.
