    摘要： Medical devices for implantation in a body vessel are provided. A medical device according to the invention comprises a support structure and one or more graft members comprising a valve portion and a constraining portion. The support structure has a first, unexpanded configuration and a second, expanded configuration. The constraining portion is adapted to substantially prevent the support structure from achieving the second, expanded configuration. The valve portion is adapted to permit fluid flow through a body vessel in a first direction and substantially prevent fluid flow through the vessel in a second, opposite direction.

    摘要： A delivery system (10) for implanting a medical device (30) such as a venous valve into the vasculature of a patient. The delivery system includes a delivery catheter (11) having a device-containing portion (15) adjacent to the distal end (14) thereof, and an inner member (16) extending through the catheter and beyond the distal end thereof, to an atraumatic distal tip portion (17) forward of the catheter distal end. Delivery catheter (11) includes inner tube (122), flat wire coil (123) compression fitted therearound, and outer tube (112) mechanically connected to roughened outer surface (126) of the inner tube through the spacing of the coil. Delivery catheter (11) can be provided with a window (184) to allow fluoroscopic visualization of a stent valve within the delivery system.

    摘要： An expandable venous valve having a support structure that configured to enlarge the area adjacent to the valve structure such that the flow patterns of retrograde flow are modified in a way that facilitates the flushing of the pockets at the base of the valve area to prevent stagnation of bodily fluid, which in the venous system, can lead to thrombus formation. The enlarged pocket areas can be created by forming an artificial sinus adjacent the valve structure in an unsupported section of vessel wall between two support frame section or the support frame can comprise an expanded-diameter intermediate or proximal section that forms an artificial sinus adjacent the valve structure. In another group of embodiments, the attachment pathway between opposing leaflets and the support frame and/or vessel wall comprises a proximal portion that places the leaflets in extended contact with one another and a distal portion forms a large angle with respect to the adjacent walls such that a large pocket is created at the base of the leaflets. In one embodiment, the attachment pathway extends distally along a pair of substantially parallel longitudinal attachment struts to create an extended leaflet contact area, then angles circumferentially and distally from the former along distal attachment struts to define the bottom edge of the leaflets.

    摘要： A venous valve prosthesis having a substantially non-expandable, valve portion comprising a valve-closing mechanism, such as a pair of opposing leaflets; and an anchoring portion, such as one or more self-expanding frames or stents that are expandable to anchor the prosthesis at the implantation site. In one embodiment, the rigid valve portion includes a deposition of material such as pyrolitic carbon to reduce the thrombogenecity of the blood-contacting surfaces. The anchoring portions preferably include a covering, such as a tubular construct of synthetic or collagen-derived material (such as a bioremodelable ECM material), which attaches about the support structure such that blood flow is directed through the valve mechanism as it transitions from the larger diameter anchoring portion to the intermediate, smaller-diameter portion of the prosthesis. In another embodiment, the valve support housing and valve-closing elements are delivered in a collapsed, folded, and/or dissembled state sized for delivery, then manipulated in situ to the second expanded configured following deployment.

    摘要： Implantable frames for use in body passages are provided herein. The implantable frames can include a plurality of hoop members joined by a plurality of longitudinal connecting members to form a tubular frame defining a cylindrical lumen. The plurality of longitudinal connecting members may include one or more pairs of closely-spaced longitudinal connecting members aligned substantially parallel to the longitudinal axis of the implantable frame. The circumferential distance between the closely-spaced longitudinal connecting members preferably subtends an angle less than (2π/n) radians, where (n) is an integer equal to the total number of longitudinal connecting members connecting two longitudinally adjacent hoop members.

    摘要： Implantable frames for use in body passages are provided herein. The implantable frames comprise one or more of certain preferred structural features that are generally applicable to frames comprising a plurality of curved and straight member portions that together define an interior lumen extending along a longitudinal axis between a proximal end and a distal end. The implantable frames have an exterior surface comprising a plurality of openings between the interior lumen and the exterior surface, and preferably include one or more undulating hoop members attached to one or more longitudinal connecting members. The implantable frames can be formed from any suitable material, but preferably comprise material permitting the frame to radially self-expand from a radially compressed configuration to a radially expanded configuration. The implantable frames are useful for endolumenal implantation within a body vessel, for example as a stent or as a support frame of an implantable valve.
