Abstract

Background Aneurysm coil technology has evolved to require near instant detachment times and near perfect detachment performance. We evaluated the new Target coil to determine device safety and acute performance.

Materials and Methods At two large high volume international centers, between November 2010 and February 2012, 211 aneurysms were coiled with Target coils; 127 elective and 84 ruptured. Average aneurysm dimensions were 5.51 mm × 4.01 mm × 3.89 mm with 17% PCOM, 21% ICA, 31% ACOM and the remaining Basilar, MCA and Vertebral. 62% of the cases were treated with balloon assisted coiling, 5% were stent assisted coiling, and 7% utilized both balloons and stents. 77% of the cases achieved a Raymond Scale of 1, 21% achieved a Raymond scale of 2, and 1.5% were Raymond Scale of 3. We experienced a 5% procedural complication rate, of which 4% were thromboembolic. There was one vessel injury related to balloon remodeling, one vessel perforation retrieving an errant coil and one perforation during coiling. Detachment times were evaluated in the first 26 cases utilizing 11 coils and showed all coils detached, with 90% in the first cycle. The original detachment time was 7.1 s. The detachment handle was altered to shorten the detachment cycle after the first 44 coils. The detachment time was then found to be 5.7 seconds for the last 67 coils. We continue to use the coils and will update results at time of the meeting.

Discussion The new Target coil combines the device performance of the GDC coil with an advanced pusher wire and detachment mechanism that allowed rapid and reliable coil performance. This can translate into faster operating times with improved device performance resulting in safer operations and better clinical outcomes.
