Patent Images
1. An aneurysm treatment system comprising:
- a catheter with a distal marker and a proximal reference marker;
an implant pusher; and
an implant connected to a distal end of the implant pusher and comprising a bulbous portion and a tail portion, the tail portion adapted to be received in a linear configuration within the catheter with a distal end of the tail portion being proximal to the bulbous portion when the implant is in an intermediate stage, the tail portion defining an inset within the bulbous portion when the implant is in a final stage,wherein at least one of the pusher and the implant comprises an implant marker, wherein when the implant marker is aligned with the proximal reference marker, the implant is in the intermediate stage with the bulbous portion of the implant deployed from the catheter, wherein, when the implant marker is aligned with the distal marker, the implant is in the final stage with the implant deployed from the catheter and the tail portion defining the inset within the bulbous portion, wherein the implant has a height that is approximately the same in the intermediate stage and in the final stage.

Abstract
Embolic implants, delivery systems and methods of manufacture and delivery are disclosed. The subject implants are deployed in two stages. If sized properly as observed in the first stage, they are deployed to the second stage and detached. If not sized properly in/at the first stage, the implants are designed to be withdrawn and replaced with a more appropriately sized implant or another treatment option selected. Some of the implant configurations may be withdrawn even after the second stage deployment as well.
