6results about "Venous valves" patented technology

The invention relates to a medical implant (1) such as an implantable valve. The medical implant (1) comprises a main body (2) and a leaflet assembly (5). The leaflet assembly (5) is formed separate from the main body (2) and is attachable or attached thereto.

Apparatus for progressively dilating the lumen of a narrow natural vessel (60) such as an iliac artery and implanting a tubular device (240) enabling access through the dilated lumen to conduct subsequent procedures via the dilated lumen, includes an inflatable integrated balloon (245) locatable at least partially within the tubular device, the tubular device (240) having a length L1 providing a self-expanding tubular body having at least a portion (250) including stents (244), so that when the integrated balloon (245) is removed the dilated lumen of the natural vessel (60) remains dilated and supported by the tubular device (240).

Fixation device for fixation of leaflets of a heart valve includes a central assembly and at least one arm moveably coupled to the central assembly. The at least one arm includes a body portion having a first end and a second end and a longitudinal axis defined therebetween, the second end being moveable between a closed position and an open position, the body portion having opposing body lateral sides, each body lateral side extending between the first end and the second end, the body portion having a body portion width defined between the opposing body lateral sides. The at least one arm further includes first and second nondeformable wing extensions, each wing extension extending laterally from a respective lateral side, each wing extension having a lateral outer edge, wherein a maximum arm width is defined between the outer lateral edge of the first wing extension and the outer lateral edge of the second wing extension. The fixation device further includes at least one gripping element moveable relative to the at least one arm to capture a native leaflet therebetween.

A replacement heart valve device is disclosed. In some embodiments, the device includes a frame coupled to one or more leaflets that are moveable between open and closed configurations. In some embodiments, the frame comprises at least two frame sections that join at a pair of commissural posts. In some embodiments, the device may be geometrically accommodating to adapt to different vasculature shapes and sizes and / or to be able to change size while implanted within a growing patient.
