Abstract
Abstract An intra-luminal device comprises a flow retainer and/or modulator for maintaining an embolic mass within an aneurysm and, optionally, for diverting or modulating fluid flow, and an anchoring element for fixating the retainer within a lumen in a patient's body. The retainer is introduced into the body lumen and positioned with the retainer across the entrance to a body cavity or a body lumen with an embolic mass disposed within to prevent the embolic mass from migrating into the patient's vasculature. The retainer may also be a diverter or modulator used to divert or modulate the luminal fluid flow to the entrance to the body cavity or lumen. The anchoring element, which may be attached to the retainer, is deployed to permanently secure the retainer within the body lumen in the desired position.
