“…Giant aneurysms present unique challenges for achieving and maintaining access, including unfavorable angles between the inflow and outflow tracts, flow characteristics, and wide or complex necks. 2,6,7 Previously proposed techniques to maintain access while intra-aneurysmal looping are reduced or while the necessary larger catheters are advanced include balloons, 1,7,9,10 detachable coils, 2 stents, 6,11–16 microwires, 17 stent retrievers, 18,19 and the rapid pull-back technique. 20 In this study, the results suggested that the Stabilizer could be used for multiple techniques while treating a giant aneurysm, including straightening of intra-aneurysmal looping, exchange for a stent delivery catheter, and advancement of an intermediate catheter.…”

Objective Neuroendovascular procedures rely on successful navigation and stable access to the target vessel. The Stabilizer is a 300 cm long exchange wire with a 0.014 diameter and a soft, flexible stent at the distal end designed to assist with navigation and device delivery. This study aims to assess the efficacy of the Stabilizer for navigation in a variety of challenging environments. Methods The efficacy of the Stabilizer was evaluated using three challenging vascular models: a giant aneurysm model, a severe tortuosity model, and an M1 stenosis model. The Stabilizer was compared with a conventional wire during navigation in each model. Results In the giant aneurysm model, there was no significant difference of success during straightening of a looped wire and significantly higher success rates when advancing an intermediate catheter with the Stabilizer beyond the aneurysm neck compared to a conventional guidewire. The Stabilizer also significantly increased success rates when advancing an intermediate catheter through a model with severe tortuosity compared to a conventional guidewire, as well as exchange maneuver for intracranial stenting in a stenosis model compared to an exchange wire. Conclusions In our experimental model, the Stabilizer significantly improved navigation and device delivery in a variety of challenging settings compared to conventional wires.

BackgroundEndovascular treatment of wide-necked aneurysms remains challenging without the use of adjunctive devices to preserve the parent artery.ObjectiveTo present our initial experience with a temporary bridging device, the Comaneci (Rapid Medical, Israel). The compliant remodeling mesh protects the parent artery during coil occlusion without flow arrest in the distal vasculature. Permanent dual antiplatelet therapy is not required since the device is fully removed at the end of the procedure.MethodsAll intracranial aneurysms treated by coil occlusion with the Comaneci device between December 2014 and November 2015 were included. Angiographic and clinical results were retrospectively analysed, including follow-up examinations. All aneurysms were unruptured.Results18 aneurysms of the internal carotid artery were included. Successful coil occlusion assisted by the Comaneci device as intended was possible in 14 cases (77.8%). Insufficient coverage of the aneurysmal neck was observed in four cases (22.2%), with modification of the treatment to stent-assisted coiling or remodeling. One clinically relevant complication occurred (5.6%).ConclusionsOur initial experience shows that use of the Comaneci device is straightforward for the treatment of selected wide-necked aneurysms. Further studies with long-term follow-up data are needed to identify the significance of the presented technique in the neurointerventional armamentarium.

Preliminary Experience with the TransForm Occlusion Balloon Catheter: Safety and Potential Advantages

Abstract: The TOBC was shown to be safe and effective for the treatment of intracranial aneurysms with BAC. In addition, it was successfully employed to perform angioplasty for vasospasm and BTO. Finally, it was used in the balloon anchor technique for the first time.
