The PulseRider device is intended for use with embolic coils for the treatment of unruptured wide-neck intracranial aneurysms originating on or near a vessel bifurcation. The PulseRider has a unique arch design with concentrated coverage at the neck allowing attenuated coil packing, and open architecture in the branch vessels eliminates struts crossing through the lumen of the branch vessels.

Incidental large basilar artery aneurysm in a 60-year-old woman (case 1). A, The angiogram shows a 17-mm aneurysm with an 8-mm neck. B, 3D reconstruction after rotational angiography shows the PulseRider device placement before coiling. C and D, An angiogram at the end of the procedure shows final complete aneurysm occlusion. E, Angiographic follow-up at 6 months reveals complete aneurysm occlusion with an occlusion of the P1 segment of the posterior cerebral artery, which was supplied by the internal carotid artery via the posterior communicating artery (F). The patient was asymptomatic.

A wide-neck anterior communicating artery aneurysm in a 50-year-old woman (case 2). A, 3D reconstruction after rotational angiography shows a large anterior communicating artery with a 4.2-mm neck. B, Subtracted angiography shows a large anterior communicating artery. C and D, PulseRider stent-assisted coiling was performed. E and F, Subtracted angiographies at the end of the procedure show a neck remnant. The PulseRider device retained coils within the aneurysm sac.

An unruptured basilar tip aneurysm in a 60-year-old man (case 3). A, Subtracted angiography shows a large basilar tip aneurysm with a 4-mm-wide neck. B–D, Endovascular treatment was performed by using a PulseRider device. E, Subtracted angiography at the end of the procedure shows complete aneurysm occlusion. F, MRA at 1 day shows complete occlusion.
