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.

Medical device delivery devices, systems, and methods

Vascular expandable devices and associated methods are disclosed herein. An expandable vascular device can include a generally tubular sidewall formed of a plurality of braided strands. The device can have a compressed state for delivery in which the device has a compressed state diameter of 0.027 inches or less. The device can have an expanded state in which the device has an expanded state diameter. A full expansion distance of the device corresponds to a longitudinal unconstrained distance at which the distal end of the expandable device attains the expanded state diameter. The full expansion distance can be 20 mm or less.

Vascular expandable devices

Vascular expandable devices and associated methods are disclosed herein. An expandable vascular device can be implantable across an aneurysm in a blood vessel of a patient. The device can include a generally tubular structure formed of a plurality of braided metallic elements. The device can have a compressed state with a compressed state diameter of 0.027 inches or less and an expanded state with an expanded state diameter of 1.75 mm or more. Each of the plurality of metallic strands can have an oxide layer having a thickness of about 400 angstroms or less. The tubular structure can be configured to self-expand from the compressed state to the expanded state.

A stent delivery system can include a core assembly sized for insertion into a corporeal lumen and configured for advancing a stent toward a treatment location in the corporeal lumen. The core assembly can include a proximal restraint having a bumper section, a distal section distal to the bumper section, a lumen extending through the bumper and distal sections, and an undercut section including a recess at least partially surrounding the lumen. The recess can abut and/or be formed in the bumper and/or distal sections.
