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: Devices and methods for removing a foreign object from a body lumen are disclosed. An embolectomy device can include a filter basket having a plurality of filter struts forming a cage-like structure that can be expanded to circumferentially surround the incoming foreign object. A support frame including a proximal hoop and one or more rail members may be employed to support the filter basket. The support frame and filter basket can be coupled to a pusher wire that can be used to manipulate the device within the body. In certain embodiments, the filter struts may vary in thickness to impart a desired flexibility characteristic to the device. Methods of manufacturing such devices are also disclosed.

摘要: Disclosed are methods and devices for navigating a subarachnoid space in a vertebrate organism including percutaneously introducing a device into the spinal subarachnoid space at an entry location. Navigation of the spinal subarachnoid space is disclosed for the purpose of reaching a desired location in the subarachnoid space or the intracranial space, including areas in and around the spinal cord and brain. Once a desired location is reached, methods and devices for cooling or heating the desired location to cause physiologic changes are suggested.

摘要: A variety of devices for use in accessing the subarachnoid space are described. In several embodiments an introducer sheath is disclosed having three main sections, a distal portion, an intermediate portion, and a proximal portion. The distal portion and intermediate portion form a first bend, and the intermediate portion and the proximal portion form a second bend, giving the overall device a general L-shape, S-shape, C-shape, or a three dimensional Z-shape. Apparatuses for attaching an introducer sheath to the skin of a patient are also discussed, as are methods for using, shaping and sizing an introducer sheath.
