Problems solved by technology

These prior devices, however, have proven to be difficult to employ, oftentimes do not lend themselves to deployment in all sizes of aneurysms, can be imprecise in their deployment, their installation can be very time consuming, risk rupture of the aneurysm because they increase its size, can risk recanalization and / or migration of the device in the patient's vasculature, and may not treat the mass effect that the aneurysm may have caused.
Furthermore, the present of adhesions in the aneurysm makes it difficult to collapse the aneurysm.

Embodiment Construction

[0027] Apparatus and methods in accordance with the present invention have numerous advantages over prior aneurysm clips and methods. Among these advantages, immediate closure of an aneurysm can be achieved with a relatively easy-to-use method. The apparatus and methods can be used to treat all aneurysms regardless of the size or the neck width, and can achieve precise locational deployment and decreased procedure time. The risk of rupture can be decreased, since the aneurysm volume is never increased. Additionally, occlusion of the aneurysm neck can be achieved by a balloon in case rupture does occur. Decreased risk of distal embolization, little or no risk of recanalization or migration, strengthening of the arterial wall at the site of the aneurysm, good visualization of the device during and after deployment, and immediate elimination of any mass effect the aneurysm may have caused can also be achieved.

Abstract

An self-expanding frame is mounted on the distal end of a shaft. The frame is sized and configured so that it can be inserted into the cavity of an aneurysm. Suction is applied to the interior of the aneurysm through the shaft or through another catheter, and the wall of the aneurysm is collapsed onto the exterior surface of the frame. The frame is then collapsed upon further suction being applied to the interior of the aneurysm, which collapses the aneurysm wall with it. The frame folds down on itself, carrying with it the aneurysm wall. The frame is detachable from the shaft and can be left in the collapsed aneurysm.

Description

[0001] This application is related to and claims priority under 35 U.S.C. §119 to U.S. provisional patent application Ser. No. 60 / 224,361, filed Aug. 11, 2000, the entire contents of which are incorporated by reference herein.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to systems and processes for treating an aneurysm, and more particular to an endovascular system and process for collapsing an aneurysm. [0004] 2. Discussion of Related Art [0005] Aneurysm treatments have been proposed using a wide variety of processes and devices, which have enjoyed various levels of success and acceptance. Such systems and processes include aneurysm clips, intravascular coils, intravascular injections, detachable intravascular balloons, and the like. [0006] These prior devices, however, have proven to be difficult to employ, oftentimes do not lend themselves to deployment in all sizes of aneurysms, can be imprecise in their deployment, their inst...
