Abstract:
To provide a guiding catheter.
A noncircular inner lumen guiding catheter with an assisted variable support has an inner wall defining a noncircular cross-sectional shaped lumen for use in delivery of multiple microcatheters or other devices for treatment of neurovascular defects, such as for treatment of aneurysms.
