Patent ID: 8641777

Claim:
An embolic implant for parent artery occlusion, said embolic implant characterized by a proximal end and a distal end, said embolic implant comprising: a wire frame structure characterized by a proximal end and a distal end, said wire-frame structure comprising: a pair of opposing zigzag segments including a plurality of V-shaped elements defining an open end, the V-shaped elements joined at the open end of the V-shaped elements via short longitudinally aligned struts to form a central portion of the wire-frame structure, said short struts being longitudinally displaced from each other, said V-shaped elements defining proximal or distal vertices pointing proximally or distally away from the center of the wire frame structure; a plurality of serpentine longitudinally oriented struts extending from the proximally pointing vertices of the shaped elements, said serpentine longitudinally oriented struts being joined together near the radial center of the wire-frame structure at the proximal end of the embolic implant; wherein the wireframe structure is formed of a self-expanding material; an detachment joint fixed to the proximal end of the embolic implant; and a membrane disposed over the proximal end of the embolic implant, said membrane having a proximal facing surface, said membrane being impermeable to blood on the proximal facing surface such that blood is substantially prevented from flowing through the implant when deployed in the parent artery.
