Summary:
We present our initial clinical experience of Dendron Variable Detachable System (VDS) coils, now Sapphire VDS from MTI, in the endovascular treatment of cerebral aneurysms. VDS coils, uniquely, can be detached at variable points along their length, allowing placement of as much or as little as desired of the coil within the aneurysm. Our ten patients formed part of a multicentre feasibility study. VDS coils were successfully deployed in all but one aneurysm. The electrolytic detachment mechanism with practice is both simple to use and reliable. The coils are however slightly stiffer than standard coils limiting their use in small aneurysms. This remains a technology in evolution.
