Abstract: Devices, systems, and methods for delivering an expandable member to a treatment site within a blood vessel are disclosed herein. According to some embodiments, a delivery system includes a core member and a coupling assembly carried by the core member. The coupling assembly may include an engagement member configured to engage an inner surface of an expandable member extending over the coupling assembly to facilitate delivery of the expandable member from an elongated shaft and/or resheathing of the expandable member into the elongated shaft. The engagement member can be movable between a radially compressed configuration and a radially expanded configuration.

Abstract: Medical device delivery devices, systems, and methods are disclosed herein. According to some embodiments, a medical device delivery system includes a core member and a coupling assembly positioned about the core member. The coupling assembly may include an engagement member having projections configured to engage a medical device and a release member that is movable between a compressed configuration and an expanded configuration. A medical device can extend along the core member such that, when the release member is in the compressed configuration, the projections of the engagement member engage the medical device and when the release member is in the expanded configuration, the release member prevents the projections from engaging the medical device and/or facilitates expansion of the medical device.
