Benefits of technology

[0044]A system for treatment of an aneurysm, comprising a plurality of foam components being expandable from a compressed configuration to an expanded configuration when released into an aneurysm from a catheter, each of the plurality of components having an average porosity that is different from an average porosity of another of the plurality of components, the plurality of components being positionable within the aneurysm to form a composite foam component having a composite porosity configured to provide a therapeutic effect.

Problems solved by technology

As is well known, aneurysms have thin, weak walls that are prone to rupturing.
When the weakened wall of an aneurysm ruptures, it can result in death, especially if it is a cerebral aneurysm that ruptures.

Embodiment Construction

[0242]In the following detailed description, numerous specific details are set forth to provide a full understanding of the subject technology. It should be understood that the subject technology may be practiced without some of these specific details. In other instances, well-structures and techniques have not been shown in detail so as not to obscure the subject technology.

[0243]Intrasaccular implant devices and procedures for treating aneurysms can be improved by manipulating one or more physical characteristics of the implant material. Such characteristics can include the porosity, composition, material, shape, size, interconnectedness, inter-engagement, coating, etc. By modifying one or more such characteristics, the morphology or attributes of a target aneurysm and orientation of any connecting arteries can be specifically considered and addressed to achieve superior treatment.

[0244]According to some embodiments, the porosity, composition, or material of the intrasaccular devi...

Abstract

A system for treatment of an aneurysm includes an intrasaccular device that can be delivered using a catheter. The device can include at least one expandable structure adapted to transition from a compressed configuration to an expanded configuration when released into the aneurysm. The expandable structure can have a specific shape or porosity. Multiple expandable structures can also be used, in which case each of the expandable structures can have a unique shape or porosity profile. The morphology of the aneurysm and orientation of any connecting arteries can determine the type, size, shape, number, and porosity profile of the expandable structure used in treating the aneurysm.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 725,768, filed Nov. 13, 2012, the entirety of which is incorporated herein by reference.BACKGROUND[0002]1. Field of the Inventions[0003]The present disclosure generally relates to a system and method for delivering and deploying a medical device within a vessel, more particularly, it relates to a system and method for delivering and deploying an endoluminal therapeutic device within the vasculature of a patient to embolize and occlude aneurysms, particularly, cerebral aneurysms.[0004]2. Description of the Related Art[0005]Walls of the vasculature, particularly arterial walls, may develop areas of pathological dilatation called aneurysms. As is well known, aneurysms have thin, weak walls that are prone to rupturing. Aneurysms can be the result of the vessel wall being weakened by disease, injury or a congenital abnormality. Aneurysms could be found in different part...
