Publication number: 20140172071Abstract: Described herein are flexible implantable occluding devices that can, for example, navigate the tortuous vessels of the neurovasculature. The occluding devices can also conform to the shape of the tortuous vessels of the vasculature. In some embodiments, the occluding devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. Some embodiments describe methods and apparatus for adjusting, along a length of the device, the porosity of the occluding device. In some embodiments, the occluding devices allows adequate blood flow to be provided to adjacent structures such that those structures, whether they are branch vessels or oxygen-demanding tissues, are not deprived of the necessary blood flow.Type: ApplicationFiled: September 13, 2013Publication date: June 19, 2014Applicant: COVIDIEN LPInventors: Aaron Lee Berez, Quang Quoc Tran

Publication number: 20130282096Abstract: A method of reducing blood flow within an aneurysm includes: injecting a contrast agent into a blood vessel including an aneurysm; deploying an occlusion device across the aneurysm; producing an image of the aneurysm including the contrast agent; and withdrawing the delivery device from the vessel after observing that the aneurysm has been obstructed by a desired amount. The image may be two-dimensional or three-dimensional. Observing that the aneurysm has been obstructed may include determining a degree of obstruction, for example by comparing an area or volume of the contrast agent in a first image and a second image. The desired amount may be a certain degree of obstruction, identification of a shape indicative of stasis such as a flat surface, an approximate hemisphere, a mushroom, or a crescent. If the occlusion device does not achieve the desired amount, a second occluding device may be deployed.Type: ApplicationFiled: October 16, 2012Publication date: October 24, 2013Inventors: Aaron Lee Berez, Quang Quoc Tran

Patent number: 8398701Abstract: A vascular occluding device for modifying blood flow in a vessel, while maintaining blood flow to the surrounding tissue. The occluding device includes a flexible, easily compressible and bendable occluding device that is particularly suited for treating aneurysms in the brain. The neurovascular occluding device can be deployed using a micro-catheter. The occluding device can be formed by braiding wires in a helical fashion and can have varying lattice densities along the length of the occluding device. The occluding device could also have different lattice densities for surfaces on the same radial plane.Type: GrantFiled: May 25, 2005Date of Patent: March 19, 2013Assignee: Covidien LPInventors: Aaron Lee Berez, Quang Quoc Tran
