Filter by:This is a prospective single center trial investigating the effects of prospectively measuring packing density prior to choosing Target Coils for the treatment of intracranial saccular aneurysms. Up to 25 eligible subjects with ruptured or unruptured intracranial saccular aneurysms between 4-20mm (maximum dimension), who consent to study participation, will be treated with Stryker Target Detachable Coils. Historical data from patients enrolled in the MAPS trial at the single center will be the control arm of the trial and reviewed for comparison to the prospective arm. In the control arm, the subjects received Stryker Matrix2 Detachable Coils and Guglielmi Detachable Coils and packing density was not measured prior to these procedures. The Pro-Pack Trial will evaluate the outcomes of the subjects treated with Target Coils, in whom the packing density will be actively calculated prior to coil selection. This will serve to establish that a higher packing density can be obtained by the change in methodology of coil selection and a higher packing density with lower recurrence rates.
The purpose of this observational post-marketing registry will be to collect and analyze safety, effectiveness, and quality of life outcomes, during and after treatment with the Surpass Flow Diverter. Health Economics assessments (cost data) will also be collected and analyzed.
To investigate whether stellate ganglion block is helpful to brain protection during cranial aneurysm surgery
This is a prospective, single-arm, multi-center post-marketing Study. The Study will commence as a single phase, with an optional second phase to follow at the discretion of the sponsor. Up to 300 eligible Subjects with small (< 4.9 mm) intracranial aneurysms, who consent to Study participation, will be treated in Phase 1 with MicroVention HyperSoft® 3D and HyperSoft® Helical coils with or without balloon remodeling or stent assistance at the discretion of the treating physician. The operator, at his/her discretion, may choose to frame the aneurysm with HyperSoft® 3D or any other bare metal coil but must finish the remainder of the aneurysm with HyperSoft® 3D and/or HyperSoft® Helical coils. At the discretion of the sponsor, additional patients, up to 300 patients total for the overall Study, with eligible aneurysms will be enrolled into Phase 2. In Phase 2, the aneurysm must be framed with a HydroFrame® or HydroSoft® 3D coil and filled/finished primarily with hydrogel coils. The intent to treat is to frame, fill and finish with all hydrogel coils. However, at the discretion of the treating physician, a bare platinum coil may be used to fill or finish, as long as a minimum of 50% (in total coil length) of hydrogel coils are used. Data will be collected on immediate and post-treatment angiographic occlusion rates (RRGS), new peri-procedural imaging-confirmed hemorrhage or ischemic stroke, neurological morbidity and mortality rates, recurrence rates, bleeding rates, retreatment rates, serious adverse events, >150 day angiographic occlusion rates (RRGS) and occlusion status. This will serve to establish the acute and sustained efficacy of EVT of small intracranial aneurysms with the specified microcoils, aided by balloon and/or stent remodeling where appropriate.
Patients' responses to oral antiplatelet therapy are subject to variation. Bedside monitoring offers the opportunity to improve outcomes of intracranial aneurysm patients undergoing stent deployment by individualizing therapy.This trial is designed to demonstrate the superiority of a strategy of platelet function monitoring with dose adjustment in suboptimal responders as compared to a more conventional strategy without monitoring and without dose adjustment to reduce the primary end point evaluated 6 months after stent deployment in patients with intracranial aneurysms.
The study is a prospective, multicenter single-arm cohort. Patients with wide neck bifurcation aneurysms (WNBAs) have few choices for safe and effective endovascular treatment. In this study, all patients with qualifying WNBAs will be treated with the WEB. The primary effectiveness outcome of the study is the likelihood of complete intracranial aneurysm occlusion on the 1 year angiogram as adjudicated by a core laboratory.
The purpose of this study is to assess the safety and effectiveness of the Pipeline™ device in the treatment of unruptured, wide-neck intracranial aneurysms.
The RIPAT study is a prospective, randomized, double-blind study organized by the neurovascular group of the Clinical Department of Neurosurgery of Innsbruck Medical University, Innsbruck, Austria. Patients aged 18+ in whom the treatment of an un-ruptured intracranial aneurysm is indicated are eligible for study participation. Prior to aneurysm treatment, with the patient already under general anesthesia, the blood supply to an arm will be restricted for 3x 5minutes by inflating a standard blood pressure cuff. The study hypothesis is that this "remote ischemic preconditioning" maneuver is able to prevent a stroke during the following treatment of the aneurysm.
The purpose of this clinical investigation is to evaluate the safety and effectiveness of the Barrel™ VRD when used to facilitate endovascular coiling of wide-neck bifurcating or branch intracranial aneurysms with any approved embolic coils.
The primary objective of this study is to gather data on the radiation exposure in patients treated with the Penumbra Coil 400™ System (PC 400) or conventional coils per their respective indications for use.This is a multicenter case review study of patients presenting with intracranial aneurysms who are treated with coil embolization therapy using the PC 400 or conventional coils. Data for each patient are collected acutely.Up to 90 patients treated with the PC 400 or conventional coils (2:1) at up to 15 centers in the USA will be enrolled.
