摘要： 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.

摘要： Disclosed herein are various exemplary systems, devices, and methods for inhibiting premature implant deployment. The delivery member can include a body including a lumen extending therethrough, the body including a compressed distal portion. The delivery member can include a pull wire extending through the lumen. The pull wire can include a pull wire portion that extends radially to abut a sidewall of the body to provide frictional resistance against the body. The pull wire can be positioned to secure the implantable medical device to the delivery member, and the pull wire portion can be effective to inhibit premature detachment of the implant by inhibiting proximal translation of the pull wire due to the frictional resistance provided by the pull wire portion against the body.

摘要： An apparatus for treating an aneurysm in a blood vessel includes an occlusion element including a first tubular mesh having a first end and a second end coupled together at a proximal end of the occlusion element such that an intermediate portion of the first tubular mesh between the first end and the second end includes a substantially 180 degree turn, the intermediate portion of the first tubular mesh extending distally from the proximal end of the occlusion element, wherein the intermediate portion of the first tubular mesh has a collapsed configuration and is configured to expand to an expanded. In some embodiments, the apparatus further includes a second tubular mesh having a first end and a second end coupled to the proximal end of the occlusion element such that an intermediate portion of the second tubular mesh between the first end and the second end includes a substantially 180 degree turn. In some embodiments, the apparatus further comprises a cover coupled to the proximal end of the occlusion element.
