1. An implant comprising:
- a self-expandable body having proximal and distal ends and expanded and compressed configurations,a radiopaque marker positioned within an interior volume of the body and held adjacent the distal end by at least one filament coupled to the proximal and distal ends,wherein the at least one filament crosses the interior volume of the body extending from the marker and terminating at the proximal end, andwherein the at least one filament has a length about equal to a length of the body in the compressed configuration such that (i) the marker is misaligned with respect to a longitudinal axis of the body when the implant is unconstrained in the expanded configuration and (ii) the marker is aligned with the longitudinal axis of the body when the body is in the compressed configuration.

Abstract
Embolic implants and methods of manufacture are disclosed. The implants may be used for occluding blood flow at endovascular sites. One use is in intracranial aneurysm emolization/occlusion and another in parent vessel occlusion (PVO) or sacrifice. Various features provide for improved use (e.g., regarding delivery, recapture, visualization and/or occlusion) and manufacturability.

8. An implant comprising:
-
a self-expandable body having longitudinal axis, proximal and distal ends, and expanded and compressed configurations; at least one filament, having a length about equal to a length of the body in the compressed configuration, extending within the body and coupled to the proximal and distal ends; and a radiopaque marker attached to the at least one filament such that the marker is (i) misaligned with respect to the longitudinal axis in the expanded configuration and (ii) aligned with the longitudinal axis in the compressed configuration. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

20. An implant comprising:
-
a self-expanding body having a longitudinal axis, proximal and distal ends, and expanded and compressed configurations; and a radiopaque marker component, having a length about equal to a length of the body in the compressed configuration, extending within the body and having first and second ends being coupled to the respective proximal and distal ends, the marker component being (i) misaligned with respect to the longitudinal axis, and slack under the action of gravity, in the expanded configuration and (ii) aligned with the longitudinal axis in the compressed configuration. - View Dependent Claims (21, 22)
