  • Publication number: 20210038361
    Abstract: An embolic coil with a secondary, delivered shape utilizing regions of varying stiffness is described. In some embodiments, these regions of varying stiffness are created by utilizing a larger primary wind loop diameter to create selective regions with lower stiffness and higher flexibility. In some embodiments, these regions of higher flexibility correspond to inflection regions on a complex coil shape to ease deliverability of the coil during therapeutic procedures.
