AI Technical Summary
Technical Problem
Existing implantable devices for embolization procedures face challenges in maintaining operability due to drug distribution, which causes coils to harden, reducing flexibility and effectiveness.
Method used
A retention system comprising a first coil with a higher hardness and a second coil with lower hardness, where the drug is applied only to the first coil, ensuring the second coil remains flexible and maintains operability during insertion.
Benefits of technology
The system allows for effective drug delivery to the target site while preserving the flexibility and operability of the coils, ensuring successful embolization procedures.
