    摘要： A catheter introducer sheath assembly, for introduction into a body passage of a catheter containing a filter comprises a flexible introducer sheath joined to the distal end of a closure device forming a through-passage with a diameter sufficient to pass the catheter therethrough. The closure device has a resilient member in the through-passage and two rotatable body portions, one stationary with respect to the resilient member, and the other rotatable about the axis of the resilient member with an internal cam circumferentially spaced around the axis. A compression member positioned radially in an extending aperture makes contact with both the resilient member and the cam surface to vary the through-passage allowing the operator to manually control the passage of the device. The sheath assembly receives a cathetory guidewire that slides through and extends beyond the closure device and the sheath. In another aspect, the combination sheath assembly and closure device forms a catheter introducer kit constructed to receive a stabilizer and a catheter of sufficiently large diameter to house a vena cava filter, and to pass the filter through the closure device and sheath for placement in the body by means of a dilator attached to the end of the sheath to facilitate guiding the filter to the desired position for its release from the sheath. The closure device is adjustable to prevent any backflow of fluid such as blood from the assembly during the filter placement procedure.

    摘要： A dynamic training system provides elevated load and energy demand on a rider of a moving bicycle out on the road or track. Resistance to movement of the bicycle is provided by a resistance unit which may include an eddy current brake. A processor may generate a control signal that adjusts the resistance to replicate the effort of riding a predetermined course or training protocol. Multiple riders at different times or locations can compete on a common virtual course. A stronger rider can be restrained by a heavier imposed load to keep pace together with a weaker rider, without compromising total power expenditure to keep the riders together.

    摘要： Modular endograft devices and associated systems and methods are disclosed herein. In several embodiments, an endograft system can include a first endograft device and a second endograft device that each include an integrated frame, a cover and a lumen within the cover. Each endograft device further includes a superior portion and an inferior portion. The superior portion can have a convexly curved outer wall and a septal wall. The first and second endograft devices can be configured to extend into a low-profile configuration with a first cross-sectional dimension and a first length and self-expand into an expanded configuration with a second cross-sectional dimension greater than the first cross-sectional dimension and a second length less than the first length. In the expanded configuration, the septal walls can press against each other and form a septum between the lumens of the first and second endograft devices.

    摘要： Disclosed are methods and apparatus for the provision of spinal therapy to two or more adjacent motion segments accessed through a trans-sacral approach. The spinal therapies include fusion and dynamic stabilization with and without a distraction of the most cephalad motion segment of the two or more adjacent motion segments provided therapy. The disclosure includes methods and apparatus to impart a push distraction to increase the distance between two adjacent vertebrae. Related concepts for the extraction of previously inserted devices and the delivery and removal of plugs for plugging the interior cavities of implantable devices are disclosed.

    摘要： Systems, methods, and devices for the treatment of acute ischemic stroke that provide immediate blood flow restoration to a vessel occluded by a clot and, after reestablishing blood flow, address the clot itself. Immediate blood flow restoration advantageously can facilitate natural lysis of the clot and also can reduce or obviate the concern for distal embolization due to fragmentation of the clot. Several embodiments of the invention provide for progressive, or modular, treatment based upon the nature of the clot. For example, the progressive treatment can include immediate restoration of blood flow, in-situ clot management, and/or clot removal depending on the particular circumstances of the treatment. The in-situ clot management can include, for example, lysis, maceration, and/or removal.
