Embodiment Construction

[0062] Briefly, in one aspect and in accordance with at least one embodiment of the present invention, in Figures 1 and 3-6, an aneurysm treatment device 10 is provided. Device 10 , also known as a Selective Occlusion Device (SOD), is primarily designed to treat aneurysms by removing compressive forces that dilate and damage delicate vasculature, allowing the tissue to heal and remodel back to a healthy and normal state. Types of aneurysms treatable by various embodiments of the present invention include bulging aneurysms (also sometimes called true aneurysms), dissecting aneurysms in which the layers of the vessel wall are partially peeled off, and what are known as "false" aneurysms A "false" aneurysm is defined by a relatively small opening in a patient's vessel wall that is fluidly coupled to a stem-shaped sac defined by the vessel wall.

[0063] Device 10 includes a stent 12 , a fluid flow restricting area or patch 14 , and a radiopaque marker 16 . exist Figure 2A and ...

Abstract

An occlusion system, method, and apparatus which treats an aneurysm in a primary vessel such as an intracranial vessel. Aneurysm types treatable by means of this invention include bulge (sometimes referred to as a true aneurysm), dissecting aneurysms in which the layers of vessel wall are partially delaminated, and what are referred to a "false" aneurysm defined by a relatively small opening in the parent vessel wall fluridically coupled to a bulb-shaped sac, also defined by the vessel wall. The system includes an occlusion device configured for deployment in the parent vessel that restricts fluid flow to the aneurysm. A patch on the device covers the neck of the aneurysm. The system includes a marker in a defined relationship with the patch, which allows for axial and rotational positioning of the device.

Description

technical field [0001] The present invention relates to a system, device or apparatus and method for treating aneurysms. In particular, embodiments of the present invention relate to an occlusion system deployable in intracranial vasculature to at least partially contain and treat an aneurysm. Background technique [0002] Several methods of treating aneurysms are used clinically with varying success. For example, craniotomy is a procedure in which aneurysms are located and treated outside the blood vessel. This type of surgery has significant disadvantages. For example, patients undergoing craniotomy must undergo general anesthesia. Also, the patient suffers a great deal of trauma in the area of ​​the aneurysm due to the fact that the surgeon must cut through multiple tissues to reach the aneurysm. For example, when treating brain aneurysms extravascularly, surgeons often must remove part of the patient's skull and must also injure brain tissue to reach the aneurysm. ...
