Embodiment Construction

[0059] Discussed herein are devices and methods for treating vascular defects adapted for minimally invasive deployment within a patient's vasculature, particularly within the patient's cerebral vasculature. For such embodiments that can be safely and effectively delivered to a desired treatment site and effectively deployed, some device embodiments may be configured to collapse into a low-profile constrained state having a transverse dimension suitable for use via The lumen of the microcatheter is delivered and deployed from its distal end. Embodiments of these devices may also maintain a clinically effective configuration with sufficient mechanical integrity immediately after deployment to withstand forces within the patient's vasculature for extended periods of time that would otherwise cause the deployed device to compress. There is also a need for device embodiments that can acutely occlude a patient's vascular defect during a procedure to provide more rapid feedback to t...
