    摘要: A stent assembly comprises an expandable stent having a first stent backbone which extends from the proximal end of the stent to the distal end of the stent. The stent comprises a first stent back bone oriented in a direction which is substantially parallel to a longitudinal axis of the stent, and a plurality of interconnected first stent members and second stent members. Each of the first stent members is oriented in a substantially longitudinal direction in the unexpanded state and the expanded state. Each of the second stent members is oriented in a substantially longitudinal direction in the unexpanded state and oriented in a substantially circumferential direction in the expanded state. The first stent backbone has a greater column strength than that of the plurality of interconnected stent members.

    摘要: An embolus extractor including elongate shaft having a proximal end and a distal end. The embolus extractor may include primary struts coupled to the distal end of the shaft. The struts may define a proximally disposed mouth. Additional secondary struts may be coupled along the elongate shaft to enhance the thrombus containing ability of the embolus extractor.

    摘要: A braided stent comprises a filament having at least one circular zone and at least two non-circular zones. Embodiments of the braided stent have a proximal segment, a middle segment, and a distal segment, wherein a porosity of the middle segment is lower than, a respective porosity of the proximal and distal segments. In one embodiment, a radial pressure of the middle segment is separately controlled to be different from, e.g., less than, a radial pressure of the distal segment. In another embodiment, a stiffness of the middle segment is separately controlled to be different from, e.g., less than, a stiffness of the distal segment.

    摘要: A medical system comprises an implant assembly including an elongated pusher member, an implantable device (e.g., a vaso-occlusive device) mounted to the distal end of the pusher member, and an electrolytically severable joint disposed on the pusher member, wherein the implantable device detaches from the pusher member when the severable joint is severed, the medical system comprising an electrical power supply coupled to the implant assembly, and configured for conveying a time varying signal having net positive electrical energy to the severable joint to detach the implantable device from the pusher member.
