Stent aneurysm embolization method and device

A method for treating an aneurysm of a patient, the aneurysm being separated from a vessel of the patient by a mouth that is contiguous with and communicates with the vessel and the aneurysm, comprising the steps of:

• providing an embolization element that is adapted to be positioned within the aneurysm to reduce or block the blood flow into the aneurysm, with a stent connected to the embolization element, the embolization element including an expandable member;
• introducing the embolization element and the stent into the vessel leading to and communicating with the aneurysm;
• providing a deployment device for carrying and delivering the embolization element and the stent simultaneously;
• introducing the deployment device with the embolization element and stent into the vessel of the patient via a catheter;
• directing the embolization element through said mouth into the aneurysm with the stent being located in the vessel communicating with the aneurysm;
• releasing the embolization element and the helical member from the deployment device;
• and
• withdrawing the catheter from the patient's vessel whereby the stent becomes expanded against the inner wall of the vessel.

A medical device for treating an aneurysm of a patient, the aneurysm being separated from a vessel of the patient by a mouth that is contiguous with and communicates with the vessel and the aneurysm, which comprises:

• 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 the aneurysm to reduce or block the blood flow into the aneurysm;
• 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 embolization element;
• 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 to expand against the inner wall of a vessel leading to the patient's aneurysm for anchoring the embolization element when the embolization element is directed through said mouth and positioned within the aneurysm.

• directing the embolization element through said mouth into the aneurysm with the stent being located in the vessel communicating with the aneurysm whereby the stent becomes expanded against the inner wall of the vessel for anchoring the embolization element to a degree sufficient to prevent movement and migration of the aneurysm embolization element, to avoid any excessive pressure on the aneurysm wall by the embolization element.
