Claim:
A medical device for treating a vessel of a patient comprising: an embolization element comprising a collapsible framework supporting a mesh or membrane which, when expanded, forms a generally cup-shape; said embolization element being adapted to be positioned within a first vessel to reduce or block the blood flow through the first vessel; a helical member having a proximal end and a distal end, said distal end being connected to a proximal end of said generally cup-shaped emoblization element and said proximal end being constructed and arranged to be detachable from a deployment device when the medical device has been deployed at the desired location in the patient; and said helical member being adapted for positioning within a catheter in a nonexpanded configuration and, when released from said catheter, being adapted to expand radially against the inner wall of a second vessel for anchoring the embolization element in said first vessel and is detached from the deployment device.
