摘要：
A detachable treatment device delivery system includes a delivery sheath defining a lumen, a treatment device having a proximal attachment segment, which includes an enlarged outer diameter region, configured for receipt within the delivery sheath, and a deployment wire configured for receipt within the delivery sheath. A delivery configuration is defined by an overlap of a distal segment of the deployment wire and the enlarged outer diameter region within an attachment zone of the delivery sheath. The deployment wire and the treatment device have a combined outer diameter at the overlap, and, in the delivery configuration, the overlap is proximally spaced from a narrowed diameter region of the attachment zone, which has a smaller diameter than the combined outer diameter. In a deployed configuration, the deployment wire is proximally spaced from the attachment zone, and the proximal attachment segment is permitted to advance through the distal opening.
