    Abstract: A stent delivery system can include a core member, first and second restraints, and a stent engagement component. The core member can have a distal segment. The first and second restraints can be coupled to the core member distal segment and axially spaced apart from each other to provide an axial gap. The first and second restraints can each have an outer profile that tapers radially inwardly in directions away from the gap. The stent engagement component can be at least partially disposed in the axial gap between the first and second restraints such that the component is slidably and rotatably coupled to the core member distal segment.

    Abstract: A vascular remodeling device has a plurality of sections, sized for deployment in a blood vessel, that is radially expandable from a collapsed state to an expanded state. Each section has a plurality of interconnected struts that define a waist, a proximal face, and a distal face. Each face comprises (i) a plurality of distal strut portions extending proximally from a distal side of the face, (ii) a plurality of proximal strut portions extending distally from a proximal side of the face, and (iii) a plurality of sub-struts, wherein, from each proximal strut portion, two of the sub-struts each extend to a different one of the distal strut portions.

    Abstract: Devices for loading intravascular treatment devices into a sheath and associated systems and methods are disclosed herein. A sheathing tool may include, for example, a first channel extending to a first opening, the first channel configured to receive a treatment device in a constrained state therethrough. The treatment device may include an elongated member and a first element and a second element at a distal region of the elongated member. The second channel may extend to a second opening, the second opening surrounded by a sidewall and configured to receive the treatment device in the constrained state therethrough, wherein the second opening is spaced apart from the first opening by a gap, and wherein a length of the gap is great enough to allow the first element to self-expand over the sidewall while the second element generally maintains its diameter in the constrained state while crossing the gap.

    Abstract: The medical device can comprise a manipulation member, a mechanical thrombectomy apparatus attached to a distal end of the manipulation member, and flow-restricting apparatus attached to the manipulation member to a location proximal to the mechanical thrombectomy apparatus. A method, for retrieving thrombus from a blood vessel, can comprise advancing a single elongate delivery member carrying a mechanical thrombectomy apparatus and a flow-restricting apparatus through a catheter to the blood vessel, expanding the thrombectomy apparatus and capturing the thrombus with the thrombectomy device, expanding the flow-restricting apparatus to at least partially occlude blood flow toward the thrombus, retracting at least a portion of the thrombectomy apparatus into the flow-restricting apparatus, and retracting the flow-restricting apparatus and the thrombectomy apparatus into the retrieval catheter.
