A stent assembly system and a stent assembly method are provided. The stent assembly system includes a stent and an assembly instrument; the assembly instrument is configured to assemble and deliver the stent, and includes a sheath core tube, an outer sheath tube, and an assembly part; the outer sheath tube slidably surrounds the sheath core tube in an axial direction; an accommodating cavity for accommodating the stent is formed between the inner wall of the outer sheath tube and the outer wall of the sheath core tube; the assembly part has a fixed end and a free end opposite to the fixed end, and the fixed end is connected to the sheath core tube; and when the stent is crimped radially on the sheath core tube, the free end is hooked to the stent to limit the stent.

An aortic graft assembly includes a tubular component that defines a wall aperture having a proximal end that extends perpendicular to a major longitudinal axis of the tubular aortic component, and a tunnel graft connected to the wall of the tubular aortic component and extending from the wall aperture toward a proximal end of the tubular aortic component. The aortic graft assembly is delivered to a patient through the wall aperture and into interfering relation with the tunnel graft to treat aortic aneurysms.

A system including a self-expanding prosthesis configured to foreshorten during deployment thereof and a delivery device configured to percutaneously deliver the self-expanding prosthesis. The delivery device includes a handle having an actuator thereon, an outer sheath including a proximal end coupled to the handle and a pusher shaft slidingly disposed within the outer sheath. The pusher shaft has a proximal end coupled to the handle and a distal end configured to releasably couple to the self-expanding prosthesis such that the self-expanding prosthesis axially moves therewith. The inner shaft has a distal portion of the inner shaft that is configured to receive a self-expanding prosthesis thereon. The outer sheath and the pusher shaft are configured to simultaneously move in opposing axial directions via actuation of the actuator on the handle to compensate for the foreshortening of the self-expanding prosthesis during deployment.

A catheter device for transporting an implant to a target location in a body lumen and also for releasing the implant at the target location. The device includes an outer shaft configured to transport the implant to the target location, and an implant capsule configured to receive the implant. The implant capsule has a tubular capsule core, which surrounds the implant prior to the release. The capsule core, at a proximal end of the capsule core, has a plurality of tabs for fixing the capsule core to the outer shaft, which tabs protrude from a tubular portion of the capsule core along an axial direction of the capsule core.

Method of endovascular intervention in neurovascular anatomy of a patient including deploying an anchor of a tethering device in an anchoring vessel of a neurovascular anatomy, the anchor coupled to a tether extending proximally from the anchor. Method includes advancing a guide-sheath over the tether of the tethering device anchored in the anchoring vessel and attached to the tether, the guide-sheath includes at least one lumen and a distal opening from the lumen. Method includes advancing a treatment device through the lumen of the guide-sheath and out the distal opening from the at least one lumen and through an entrance of a target intracranial vessel, and deploying the treatment device at a treatment site within the target intracranial vessel without a combined therapy of two or more anti-platelet therapeutic agents during a peri-procedural period. Related systems, devices, and methods are disclosed.

A system for implantation of a stent in a body lumen may include an elongate tubular member having a lumen extending therein, a stent configured to shift from a delivery configuration to a deployed configuration, and an adhesive structure configured to secure the stent to the body lumen in the deployed configuration. The stent may be disposed within the lumen of the elongate tubular member in the delivery configuration. The adhesive structure may be disposed within the lumen of the elongate tubular member adjacent the stent in a substantially inert state. The adhesive structure may be configured to adhere to the stent and the body lumen after the stent and the adhesive structure are deployed into the body lumen from the lumen of the elongate tubular member.
