Stent aneurysm embolization method and device
First Claim
1. A method for treating an aneurysm of a patient comprising the steps of:
- providing an embolization element that is adapted 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;
directing the embolization element into the aneurysm with the stent being located in the vessel communicating with the aneurysm whereby the stent becomes compressed against the inner wall of the vessel for anchoring the embolization element.

Abstract
A method and device used for treating an aneurysm of a patient. An embolization element that is adapted to reduce or block the blood flow into the aneurysm, together with a stent connected to the embolization element, is provided. The embolization element includes an expandible member. The embolization element and the stent are introduced into the vessel leading to and communicating with the aneurysm. The embolization element is directed into the aneurysm, with the stent being located in the vessel communicating with the aneurysm. In this manner, the stent becomes compressed against the inner wall of the vessel for anchoring the embolization element. In one form of the invention, the stent comprises a helical coil and the embolization element comprises a collapsible framework.

14. A method for treating an aneurysm of a patient comprising the steps of:
-
providing an embolization element that is adapted 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 into the aneurysm with a 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 compressed against the inner wall of the vessel. - View Dependent Claims (15, 16, 17, 18, 19)

20. A medical device for treating an aneurysm of a patient, which comprises:
-
an embolization element comprising a collapsible framework supporting a mesh or membrane which, when expanded, forms a generally cup-shape;
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 compress against the inner wall of a vessel leading to the patient'"'"'s aneurysm for anchoring the embolization element when the embolization element is positioned within the aneurysm. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
