Abstract:
A vascular occlusion device includes a braided filament mesh structure defining a longitudinal axis. The mesh structure has a relaxed configuration in which it has an axial array of radially-extending occlusion regions, each of which has a proximal side and a distal side meeting at a peripheral edge, the sides of each occlusion region forming a first angle relative to the longitudinal axis. Each occlusion region is axially separated from the adjacent occlusion region by a reduced-diameter connecting region. The mesh structure is radially compressible to a compressed state in which it is deployed intravascularly to a target site through a catheter. Upon deployment, the device radially expands to a constrained configuration in which the peripheral edges of the occlusion regions engage the vascular wall, and the sides of the occlusion regions form a second angle relative to the longitudinal axis that is smaller than the first angle.

Claim (Index 25):
A method for occluding a blood vessel, comprising the steps of:\n (a) providing a catheter dimensioned to be introduced intravascularly to a target vascular site; the catheter having a lumen between a distal open end and a proximal open end; (b) providing an occlusion device having a longitudinal axis between a proximal device end and a distal device end, the occlusion device comprising a braided filament mesh extending between the proximal device end and the distal device end, the filaments terminating at the proximal device end in a proximal hub and at the distal device end in a distal hub, wherein the occlusion device has a relaxed configuration in which the occlusion device has a plurality of radially-extending occlusion regions, wherein each radially-extending occlusion region has a proximal side and a distal side that meet at a peripheral edge; (c) advancing the catheter intravascularly to position its distal open end in or near the target vascular site; (d) advancing the occlusion device, in a radially-compressed configuration, distally through the lumen of the catheter until the occlusion device emerges from the open distal end of the catheter for deployment in the target vascular site; (e) allowing the occlusion device to expand radially at the target vascular site until the peripheral edge of each radially-extending occlusion region engages an endoluminal surface of the target vascular site, wherein when the occlusion device is deployed, each radially extending occlusion region defines two radial traverses of the lumen for each filament, wherein the total number of radial filament traverses is between 720 and 2000; and (f) maintaining the occlusion device in the target vascular site at least until the target vascular site is embolized to occlude blood flow through the target vascular site.
