An aneurysm treatment system (100) that includes an embolic implant (140), a delivery system, and an introducer sheath (180) that are collectively designed so that the combination of the introducer sheath (180) and the delivery system can be used as a deployment apparatus for the embolic implant (140). The delivery system can have a pull wire (130), a delivery tube (110), and an interference feature (120) attached to the pull wire (130) and positioned near a proximal end of the delivery tube (110). Rather than being discarded, the introducer sheath (180) can be moved proximally over the delivery tube (110) until it engages the interference feature (120). To deploy the implant (140), the introducer sheath (180) can be pressed against the interference feature (120), causing the interference feature (120) to move proximally in relation to the delivery tube (110), thereby proximally pulling the pull wire (130) to which the interference feature (120) is attached and deploying the implant (140).
