Benefits of technology

[0010] In any of the devices described herein, the upper member may comprise a plurality of axially moveable wires passing through the lumen of the central member, each wire comprising a distal end and a proximal end. In certain embodiments, the distal end of one or more of the wires is attached to the central member and / or to the lower member. The upper member may be compressible or deformable, for example against the dome of an aneurysm, thereby changing the overall dimensions of the device.

Problems solved by technology

An aneurysm is a dilation of a blood vessel that poses a risk to health from the potential for rupture, clotting, or dissecting.
Rupture of an aneurysm in the brain causes stroke, and rupture of an aneurysm in the abdomen causes shock.
Cerebral aneurysms are usually detected in patients as the result of a seizure or hemorrhage and can result in significant morbidity or mortality.
However, there is a risk that known coil designs will migrate fully or partially out of the aneurysm entrance zone and into the feeding vessel.
This risk is particularly high with wide neck aneurysms.

Embodiment Construction

[0028] Occlusive (e.g., embolic) devices are described. The devices described herein find use in vascular and neurovascular indications and are particularly useful in treating aneurysms, for example wide-neck, small-diameter, curved or otherwise difficult to access vasculature, for example aneurysms, such as cerebral aneurysms. Methods of making and using these vaso-occlusive devices also form aspects of this invention.

[0029] All publications, patents and patent applications cited herein, whether above or below, are hereby incorporated by reference in their entirety.

[0030] It must be noted that, as used in this specification and the appended claims, the singular forms “a”, “an”, and “the” include plural references unless the content clearly dictates otherwise. Thus, for example, reference to a device comprising “an extendable member” includes devices comprising of two or more elements.

[0031] The device is a surgical implement and can be readily deployed, removed and / or reposition...

Abstract

Devices for occluding an aneurysm are provided. In particular, the device include an upper member that sits against the dome of the aneurysm, a lower member that sits in the neck of the aneurysm, and a means of adjusting the overall dimensions of the device. Also provided are methods of making and using these devices.

Description

FIELD OF THE INVENTION [0001] Compositions and methods for repair and treatment of aneurysms are described. In particular, devices and systems for placement in an aneurysm are disclosed, as are methods of making and using these devices. BACKGROUND [0002] An aneurysm is a dilation of a blood vessel that poses a risk to health from the potential for rupture, clotting, or dissecting. Rupture of an aneurysm in the brain causes stroke, and rupture of an aneurysm in the abdomen causes shock. Cerebral aneurysms are usually detected in patients as the result of a seizure or hemorrhage and can result in significant morbidity or mortality. [0003] There are a variety of materials and devices which have been used for treatment of aneurysms, including platinum and stainless steel microcoils, polyvinyl alcohol sponges (Ivalone), and other mechanical devices. For example, vaso-occlusion devices are surgical implements or implants that are placed within the vasculature of the human body, typically ...
