International Classification:

A61F 2/06

US Classification:

623 124

Abstract:

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.

International Classification:

A61F 2/06

US Classification:

623 124, 623 238

Abstract:

Described are vascular valve devices for implantation in a patient. The vascular valve devices are designed to compensate for the retraction characteristics of a remodelable material used to form one or more leaflets. Alternatively, or in addition, the devices are designed to reduce retraction of the remodelable leaflet-forming material. Further described are methods for preparing and using these vascular valve devices.

US Classification:

623 124, 623 214, 623 217

Abstract:

An valve prosthesis, such as an artificial venous valve, having a support frame and leaf structure comprising one or more leaflets in which the outer edge of each leaflet engages the inner circumference of the bodily passageway along a serpentine path urged against the passageway by an expandable frame, while the inner edges move in response to fluid to restrict retrograde flow. Optionally, one or more elements can extend from the support frame/leaf structure to provide centering support and/or protection from the leaflet adhering to the vessel wall. In one embodiment, the centering support structure comprises a second or third expandable frames attached to and extending from the proximal and/or distal ends of main valve structure and support frame. In another embodiment, one or more support elements extend outward from the valve support frame to engage the vessel wall to provide greater longitudinal stability.

US Classification:

623 126, 623 124, 623 214, 623 218

Abstract:

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.

US Classification:

623 115, 623 117, 623 122

Abstract:

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.

International Classification:

A61F 2/06

US Classification:

623 115

Abstract:

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.
