Cerebral aneurysms, also known as intracranial or brain aneurysms, occur most commonly in the anterior cerebral artery, which is part of the circle of Willis. This can cause severe strokes leading to death. The next most common sites of cerebral aneurysm occurrence are in the internal carotid artery.
Endovascular aneurysm devices, systems, and methods
Devices, systems, and methods for implanting prostheses in the body lumens rely on tacking or anchoring the prostheses with separately introduced fasteners. After initial placement, a fastener applier system is introduced within the expanded prostheses to deploy a plurality of fasteners to at least one prosthesis end. The fasteners are usually helical fasteners which are releasably restrained on the fastener driver, and are delivered by rotation of the fastener driver. The fasteners may be applied singly, typically in circumferentially spaced-apart patterns about the interior of at least one end of the prosthesis. A lumen extension or lumens may be coupled to the prosthesis to extend the reach of the prosthesis within the implantation site. Fasteners may also be applied to the lumen extensions.

A bag for use in the intravascular treatment of saccular aneurysms and a method of forming the bag are disclosed. The bag is formed from a plurality of flexible, resilient filamentary members braided into a tubular sleeve and biased into a first shape having an expanded first diameter sized to substantially fill the aneurysm. The bag is resiliently deformable into a second shape having a diameter smaller than the first and sized to slidingly interfit within the lumen of a catheter. An opening is provided in the bag to receive a clotting medium, such as a platinum wire, on which blood clots can be induced to form by mechanical or electrolytic means. A closure is provided by biasing the filamentary members to form a constriction around the opening. In use the, bag is inserted into a saccular aneurysm via the catheter and expands to its first diameter upon release therefrom. Interstices between the interbraided filamentary members provide pores allowing blood from the aneurysm to enter the bag when the bag is positioned within the aneurysm. The clotting medium wire is packed into the bag, blood clots on the wire and occludes the aneurysm, sealing it off from the blood stream and preventing rupture. The wire is released from the catheter and is contained within the bag in the aneurysm.

Embolic balloon
An embolic balloon assembly is disclosed herein. The assembly includes a detachable balloon system which expands while aspirating a quantity of surrounding blood to occlude a vessel or aneurysm. The balloon has a distensible membrane having a plurality of orifices throughout its surface. Within the distensible membrane is a plurality of expandable members made from a shape memory alloy, e.g., Ni—Ti alloy, which expand upon application of a stimulus. Alternatively, the expandable members or a single expandable wire may be inserted separately into the distensible membrane. Once the balloon begins to expand, internal pressure within a volume defined by the distensible membrane begins to drop, forcing the device to aspirate a quantity of surrounding blood inside the volume which then begins to coagulate by stasis or some stimulus. The balloon may be configured to automatically release into the aneurysm or vessel or it may be released by a detachable joint.

Stitched stent grafts and methods for their fabrication
InactiveUS6123722AUnnecessary expansive forcePrevent radial movementStentsBlood vesselsExtensibilityStent grafting
The present invention provides modular intraluminal tubular prostheses, particularly stents and stent-grafts, for the treatment of disease conditions, particularly aneurysms. Modular sections of the prostheses, or "prosthetic modules," may be selectively combined to form a composite prosthesis having characteristics which are tailored to the specific requirements of the patient. Each prosthetic module preferably includes one or more standard interface ends for engaging another module, the module / module interface typically comprising ends which overlap and / or lock within a predetermined axial range. Advantageously, the axial length, cross-section, perimeter, resilient expansive force, axial flexibility, liner permeability, liner extensibility, radial conformability, liner / tubal wall sealing and anchoring, and other prosthetic characteristics may be varied along the axis of the composite prosthesis, and also along the axis of each prosthetic module. The modules are preferably individually introduced into a lumen system of a patient body so that the composite prosthesis is assembled in situ. Ideally, selection of appropriate prosthetic modules and the flexibility of the interface overlap range provides a custom fit intraluminal prosthesis which provides a therapy tailored to the individual patient's needs.

Intravascular deliverable stent for reinforcement of vascular abnormalities
InactiveUS20070168019A1Avoid interactionReduce overall outer diameterStentsCatheterVascular Skin TumorSaphenous veins
A catheter deliverable stent / graft especially designed to be used in a minimally invasive surgical procedure for treating a variety of vascular conditions such as aneurysms, stenotic lesions and saphenous vein grafts, comprises an innermost tubular structure and at least one further tubular member in coaxial arrangement. In one embodiment, the innermost tubular structure is of a length (L1) and is formed by braiding a relatively few strands of highly elastic metallic alloy. The pick and pitch of the braid are such as to provide relative large fenestrations in the tubular wall that permit blood flow through the wall and provide the primary radial support structure. A portion of the innermost tubular structure of a length L1 is surrounded by a further braided tubular structure having relatively many strands that substantially inhibit blood flow through the fenestrations of the innermost tubular structure. The composite structure can be stretched to reduce the outer diameter of the stent / graft, allowing it to be drawn into a lumen of a delivery catheter. The catheter can then be advanced through the vascular system to the site of treatment and then released, allowing it to self-expand against the vessel wall. Various optional embodiments are disclosed that allow one skilled in the art to tailor the design to the specific application.

Means and method for the treatment of cerebral aneurysms
Disclosed is a system for the treatment of cerebral aneurysms using a stent and a aneurysm pocket fill structure delivery system. One embodiment of the present invention uses a highly radiopaque, drug eluting stent that is deployed with its sidewall over the ostium of the aneurysm pocket. A fill structure delivery catheter is then advanced through the patient's vascular system until the catheter's distal end is situated within the aneurysm pocket. Compressed aneurysm pocket filling structures are then pushed through the fill structure delivery catheter. As the aneurysm pocket filling structures emerge from an opening in the catheter's distal end, they promptly expand so that their minimum dimension is sufficiently large so that they cannot pass through the spaces between the struts of the stent that cover the ostium of the aneurysm pocket.
