Benefits of technology

[0015]There is provided in accordance with the present invention methods and devices for treating cerebrospinal venous insufficiency, which treatment may reduce or eliminate certain symptoms of multiple sclerosis or other neurological conditions. In accordance with the methods of the present invention, a patient is identified having at least a partial o

Problems solved by technology

There also appears to be widespread axonal damage.
And yet, despite all this extensive attention and study, a cure or even an effective treatment for MS remains out of reach.
And eventually even these patients will only have their symptoms managed to maximize their quality of life as the disease inevitably progresses.
Immunosuppressive therapies have been attempted but have provided little benefit and led to substantial side effects.
However, there remains no long-term data that convincingly demonstrates a reduction

Embodiment Construction

[0068]Referring to FIG. 1, there is illustrated a simplified schematic of the venous outflow vasculature leading from the brain. As illustrated therein, venous flow from the vein is conducted via the right internal jugular vein 10 which merges with the subclavian vein 12 to form the right innominate 14, leading to the superior vena cava 16. The azygos vein 18 also leads to the superior vena cava 16.

[0069]Venous flow through the left internal jugular 20 and external jugular 22 merge with the subclavian vein 24, and lead via the left innominate 26 to the superior vena cava 16.

[0070]The extracranial venous vasculature described above is typically also characterized by the presence of a number of valves. Although patient-to-patient variation is observed, a typical patient may have a first valve 28 and a second valve 30 within the right internal jugular 10. The left internal jugular 20 may also be provided with a first valve 32 and a second valve 34. In addition, the azygos vein 18 is of...

Abstract

Methods and devices are disclosed for treating neurovascular venous outflow obstructions, with or without implantation of a prosthetic valve. The valve may be carried by a support, such as a stent, which may be self-expandable or balloon expandable. Both transvascular and direct surgical access is contemplated.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 400,383, filed Jul. 27, 2010, the entirety of this application is hereby incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]The present invention relates to methods and devices for treating neurovascular venous outflow obstructions, such as to relieve the symptoms of multiple sclerosis or other neurological conditions.[0003]Multiple Sclerosis (MS) is a debilitating disease for which modern medicine has few answers. Questions remain regarding the etiology, the disease process, and possible treatments. Since Jean Martin Charcot first described the clinical and pathological features of MS in 1868 it has perplexed physicians and scientists alike. For years the disease was described clinically, but with the advent of more sophisticated tools such as magnetic resonance imaging (MRI), the disease process was linked to plaques—or inflammatory lesions—in the ...
