Fourth Sphere Technology Patent Issued in the United States

We are happy to announce an additional patent for our Spherical Aneurysm Device technology for the treatment of cerebral aneurysms patent has issued in The United States.

Sphere is an implantable spherical device made of memory metal.  It is delivered to a location opposite the neck of a cranial saccular aneurysm located at a bifurcation point in the neurovasculature.  The device will reduce blood flow into the aneurysm, decreasing the likelihood that the aneurysm will rupture, and will facilitate clotting and vessel remodeling.

An aneurysm is a weak, enlarged area in a blood vessel.  Over time, the force of normal blood pressure can cause it to rupture.  This is fatal in 40% of all cases, and of those who survive, about 66% suffer permanent neurological deficit.  The American Association of Neurological Surgeons estimates that every year 30,000 people in the United States experience a ruptured brain aneurysm.  Aneurysms are more prevalent in people ages 50 to 60 and three times more prevalent in women.

The patent, US 8,968,382 B2, titled “Method and apparatus for restricting flow through an opening in the side wall” covers:

A single flexible closed loop stretched on a delivery system, allowing the implant to navigate through a tortuous path. The implant passively recoils when it is deployed at the site of the aneurysm. This patent describes a novel zig zag design which facilitates deployment in vivo.

The MINT Program now has 7 issued patents in the United States, 1 issued patent in Japan, and 21 active patents pending in the US and world-wide.
