A stent delivery system includes a core member and a coupling assembly rotatably coupled to the core member distal segment. The coupling assembly includes first and second plates and first and second spacers. The first plate is rotatably coupled to the core member and includes an outer surface having three or more projections separated by recesses. The first spacer is coupled to the core member and disposed between the first plate and a proximal restraint. The second plate is rotatably coupled to the core member and includes an outer surface having three or more projections separated by recesses. The second spacer is coupled to the core member and disposed between the first plate and the second plate. A stent extends along the core member distal segment such that an inner surface of the stent is engaged by one or more projections of the first plate or the second plate.

Medical device delivery

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.
