Delivery system for a self-expanding implant

摘要

The present disclosure provides a delivery system for a self-expanding implant (31) which includes a sheath (41, 42) which surrounds and constrains the implant prior to delivery and a confining element (80) which surrounds the sheath during storage. The confining element preferably includes elongate members (81) running axially along the sheath, which compress the sheath and the stent to reduce hoop stress in the system without promoting undesired adhesion between layers of the sheath.
