Abstract: Expandable prosthetic valve devices for repair or replacement of a native valve in a heart of a patient and associated, systems and methods are disclosed herein. An expandable prosthetic valve device configured in accordance with a particular embodiment of the present technology can include a radially-expandable support having an expandable outer wall and a lumen defined by the outer wall. The device can also include a valve in the lumen and coupled to the support and a self-expanding retainer coupled to the outer wall. The retainer can have a structural braid configured to form a first annular flange on the outer wall of the support, and an occlusive braid configured to reduce blood flow through the retainer.

Abstract: Embolic protection devices for placement in an arterial system of a human and methods of using such devices. In one embodiment, the device includes a filter having a first filter section configured to be deployed along the ascending aorta and aortic arch, a tapered second filter section extending proximally from the first filter section, and a proximal portion extending proximally from the second filter section. The second filter section is configured to be deployed along the descending aorta, and the proximal portion extends to a position below a renal artery. The embolic protection device can be configured to continuously filter the arterial system blood between a distal end of the first filter section to a position within the arterial system downstream of the renal artery.

Abstract: The present invention provides methods and apparatus for the endoluminal positioning of an intraluminal prosthesis at a target location within a body lumen. The device may comprise a porous, multi-layer prosthesis that can include several different tubular mesh components such as an everted tubular component, an tubular component that expands to various different sizes, a bifurcated tubular component, and a tubular component with an undulating expanded shape, among others. Various components can have different densities or pore sizes and can be overlaid on each other to selectively block different regions of a vessel.
