摘要： A medical appliance or prosthesis may comprise one or more layers of rotational spun nanofibers, including rotational spun polymers. The rotational spun material may comprise layers including layers of polytetrafluoroethylene (PTFE). Rotational spun nanofiber mats of certain porosities may permit tissue ingrowth into or attachment to the prosthesis. Additionally, one or more cuffs may be configured to allow tissue ingrowth to anchor the prosthesis.

摘要： Stent embodiments formed of a scaffolding structure are disclosed. Some embodiments may include a valve. A portion of the scaffolding structure may include a lattice structure formed by a plurality of interconnected arms arranged to form quadrilateral-shaped cells, such as diamond-shaped cells. The scaffolding structure may be formed by rows of strut arms arranged as annular segments and adjacent annular segments interconnected by connectors that extend in the longitudinal direction. The scaffolding structure may also be formed by rows of strut arms arranged in a helical pattern. The scaffolding structure has components configured to allow at least a portion of the stent to decrease in diameter in response to an axial force applied to the stent. Further, the components and elements of the stent may be configured to balance transverse forces applied to the stent, thus reducing the incidence of infolding.

摘要： Delivery systems and methods for deploying an implantable device are disclosed, which can include a delivery device having an outer tubular member and an inner assembly. The inner assembly is disposed within and is slidably movable relative to the outer tubular member. The inner assembly can include a pusher at a distal portion. The pusher abuts and restricts proximal movement, relative to the inner assembly, of a crimped implantable device within the outer tubular member. The pusher can include a slot to accommodate a suture binding mechanism of the implantable device. The delivery device can include a tip disposed at a distal end. The tip includes a tip transition zone. The inner sheath and outer tubular member can each have sections of distinct rigidity along their lengths with transition zones between the sections. A transition zone of the outer tubular member and a transition zone of the inner sheath can be longitudinally offset.
