An example stent delivery system may include an inner member. A deployment sheath may be disposed about the inner member. A stent may be disposed between the inner member and the deployment sheath. A handle may be coupled to the inner member and to the deployment sheath. The handle may include an actuation member. The actuation member may be configured to shift the longitudinal position of the deployment sheath relative to the inner member. A locking member may be disposed on the actuation member. The locking member may be configured to prevent unwanted actuation of the actuation member. ## Claims ### Claim 1 A stent delivery system, comprising: an inner member; a deployment sheath disposed about the inner member; a stent disposed between the inner member and the deployment sheath; a handle coupled to the inner member and to the deployment sheath, the handle comprising a rotatable actuation member having an outer rim and an inner portion inset relative to the outer rim, the actuation member being configured to shift the longitudinal position of the deployment sheath relative to the inner member; and a locking member comprising first and second inward-extending tabs, the locking member disposed over the outer rim of the rotatable actuation member such that the first and second inward-extending tabs each contact and apply an opposing inward force to the inner portion of the rotatable actuation member when the locking member is engaged with the actuation member to prevent unwanted actuation of the actuation member. ### Claim 2 (depends on 1) The stent delivery system of claim 1, wherein the stent includes a self-expanding stent. ### Claim 3 (depends on 1) The stent delivery system of claim 1, wherein the actuation member includes a thumbwheel. ### Claim 4 (depends on 1) The stent delivery system of claim 1, wherein the locking member is releasably attached to the actuation member. ### Claim 5 (depends on 1) The stent delivery system of claim 1, wherein the locking member includes a grip portion for attaching to the actuation member and a handle portion, and wherein the grip portion is configured to shift between an attached configuration where the locking member is attached to the actuation member and a released configuration where the locking member can be removed from the actuation member. ### Claim 6 (depends on 5) The stent delivery system of claim 5, wherein the handle portion includes one or more depressible tabs. ### Claim 7 (depends on 6) The stent delivery system of claim 6, wherein applying a radially inward force to the depressible tabs shifts the locking member from the attached configuration to the released configuration. ### Claim 8 (depends on 7) The stent delivery system of claim 7, wherein removing the radially inward force from the one or more depressible tabs shifts the locking member from the released configuration to the attached configuration. ### Claim 9 (depends on 1) The stent delivery system of claim 1, wherein the locking member includes a distal edge and a proximal edge, and wherein at least one of the distal edge and the proximal edge is configured to engage the handle. ### Claim 10 (depends on 1) The stent delivery system of claim 1, wherein the handle includes a handle body comprising at least one channel disposed adjacent to the actuation member and wherein the locking member includes at least one projection that is configured to extend downward into the channel of the handle body.
