摘要：
The present disclosure relates to the field of delivery systems for precise navigation within and through body passages. Specifically, the present disclosure relates to delivery systems for accurate positioning and release of elements within tortuous, narrow and/or fragile passages. In particular, the present disclosure relates to a delivery system that includes a distal coil with sufficient flexibility to navigate through tortuous body passages, and which allows for controlled stretch when bent.
