IMPROVED ANEURYSM OCCLUSION DEVICE
Document Type and Number:
Japanese Patent JP2020039874
Kind Code:
A
Abstract:
To provide a retrievable and repositionable device that cooperates with one or more embolic coils or other vaso-occlusive structure to effectively occlude a neck of an aneurysm or other arterio-venous malformation in a blood vessel.SOLUTION: An occlusion device 20 suitable for endovasculature treatment of an aneurysm A in a blood vessel BV in a patient includes a substantially tubular structure having a proximal end region and a distal end region 28 and having a first expanded condition and a second collapsed condition. The device 20 has dimensions in the second collapsed condition suitable for insertion through vasculature of the patient and through a neck of the aneurysm. The device further includes a control ring 22 having a substantially annular body disposed on the proximal end region of the structure to prevent radial expansion of the proximal end region and at least substantially circumscribing the proximal end region to provide an engagement feature during manipulation of the occlusion device.SELECTED DRAWING: Figure 3
