1. A device, comprising:
a catheter configured to support a self-expanding drainage device;
a retractable sheath slidably disposed over the catheter, the retractable sheath configured to deploy the self-expanding drainage device from the catheter;
a first lock having an engaged position, the first lock when in the engaged position configured to prevent movement of the retractable sheath proximally with respect to the catheter, wherein the first lock is configured to be released from the engaged position a first time to allow movement of the retractable sheath proximally with respect to the catheter; and
a lock stop configured to engage the first lock in the engaged position at a first position to prevent movement of the retractable sheath proximally, past the first position, with respect to the catheter upon initial release of the first lock,
wherein the first lock is configured to be released from the engaged position a second time to allow movement of the retractable sheath proximally past the first position,
wherein the first position corresponds to a position of the retractable sheath with respect to the catheter in which the self-expanding drainage device is partially deployed.
