Concepts disclosed relate to multi-frame prosthetic valves including leaflet and anchor frame subcomponents, where the leaflet frame subcomponent does not directly couple with patient anatomy and is separated from the anchor frame subcomponent by a gap/space. An optional connecting sheath may be provided to interconnect the subcomponents and assist with prosthetic valve delivery and deployment. One or more bridging members, or annular groove covers, are provided to bridge and cover gap or space between the anchor frame subcomponent and leaflet frame subcomponent, such as at the inflow and/or outflow ends of the subcomponents. Such bridging/cover features may provide smoother flow profiles, reduce incidence of complications, facilitate perfusion during delivery, assist with device nesting during delivery, assist with relative subcomponent positioning following delivery, or provide any of a variety of additional or alternative functions and advantages.

Valve with multi-part frame and associated resilient bridging features

A stent incorporating flexible, preferably polymeric, connecting elements into the stent wherein these elements connect adjacent, spaced-apart stent elements. Preferably the spaced-apart adjacent stent elements are the result of forming the stent from a helically wound serpentine wire having space provided between adjacent windings. Other stent forms such as multiple, individual spaced-apart ring-shaped or interconnected stent elements may also be used. The connecting elements are typically web-shaped and result from creating slits or apertures in a covering of graft material applied to the stent and then, for example, applying heat to cause the slits or apertures to enlarge. The remaining graft material forms the interconnecting webs between the adjacent stent elements.

The present disclosure describes treatment of the vasculature of a patient with an expandable implant. The implant is constrained to a reduced delivery diameter for delivery within the vasculature by at least one sleeve. The implant can be constrained to other diameters, such as an intermediate diameter. The sleeves can be expanded, allowing for expansion of the diameter of the expandable implant, by disengaging a coupling member from the sleeve or sleeves from outside of the body of the patient. The expandable implant can comprise a steering line or lines which facilitate bending and steering of the expandable implant through the vasculature of a patient.

External steerable fiber for use in endoluminal deployment of expandable devices

An implantable device is disclosed. The device includes a leaflet frame subcomponent and an anchor frame subcomponent that are configured to be delivered in a series configuration and subsequently nested or telescoped in-situ.

Telescoping prosthetic valve with retention element

Various aspects of the present disclosure are directed toward implantable medical devices, systems, and methods for cardiac assistance.

Implantable ventricular assist devices and methods

A catheter assembly for delivery of an expandable implant having at least one branch portal, which utilizes a secondary sleeve for releasably constraining a middle portion of the expandable implant after releasing a primary constraining sleeve used for constraining the expandable implant toward a delivery configuration for endoluminal delivery; and methods of using the same.
