    摘要: A prosthetic heart valve includes an annular frame that is adapted for (1) delivery into a patient's native heart valve annulus in a circumferentially collapsed condition, and (2) circumferential re-expansion when in the annulus, the frame, in an expanded condition. The frame having a longitudinal axis, an inflow end and an outflow end, a first portion of the frame adjacent the inflow end inclining radially outwardly in a direction toward the inflow end, and a second portion of the frame between the first portion and the outflow end bulging radially outwardly, the second portion of the frame being positioned between a first axial distance from the inflow end and a second axial distance from the inflow end. The frame also includes a plurality of commissure members. The heart valve further includes a flexible leaflet structure disposed in the frame.

    摘要: An embolic filter balloon is disclosed. The embolic filter balloon may comprise an inflatable balloon portion. Further, the inflatable balloon portion may be coupled to a filter member. The embolic filter balloon may be disposed in a body lumen. In some embodiments, the embolic filter balloon may be configured such that when the inflatable balloon portion is at least partially inflated the filter member extends at least partially across the body lumen. Such a configuration may allow the embolic filter balloon, when deployed, to filter particles greater than a predetermined size from a fluid in the body lumen.

    摘要: In some embodiments, a medical device for recanalizing a vessel having a blockage and restoring blood flow through an obstructed blood vessel includes an expandable member coupled to a core wire and a hypotube that are movable relative to each other to manipulate the expandable member between various configurations. The expandable member having a capture structure in an expanded configuration. The expandable member can include multiple interstices formed by woven mesh filaments or braided strands through which the material blocking the vessel can pass. The capture structure can include a shape on its external surface that facilitates dislodgement and capture of the material within capture spaces created by the expandable member. Some embodiments include a capture sack or cap for capturing material and preventing material from migrating down stream of the blockage. Superoxygenated blood can be infused distal to the blockage to minimize loss of function during an ischemic event.

    摘要: Devices for restoring blood flow to facilitate lysis of clots and/or enable capture of clots are disclosed. The devices can be configured to be disposed within a lumen of a microcatheter that is inserted within neurovasculature above a carotid siphon to a location of a clot. The devices can include an elongate pusher member and a self-expandable capturing member coupled to a distal end of the elongate pusher member. The capturing member can comprise a generally cylindrical body having an cell structure that is configured to compress the clot against an inner wall of the neurovasculature and capture the clot at least partially on a surface of the generally cylindrical body upon deployment of the capturing member from the microcatheter, thereby restoring blood flow to the neurovasculature downstream of the clot.

    摘要: An embolic protection device and medical procedure for positioning the device in the aortic arch is disclosed. The device and method effectively prevent material from entering with blood flow into side branch vessels of the aortic arch. The device is a collapsible embolic protection device devised for temporary transvascular delivery to an aortic arch of a patient, wherein the device has a protection unit that comprises a selectively permeable unit adapted to prevent embolic material from passage with a blood flow into a plurality of aortic side branch vessels at the aortic arch. The protection unit is permanently attached to a transvascular delivery unit at a connection point provided at the selectively permeable unit, and a first support member for the protection unit that is at least partly arranged at a periphery of the selectively permeable unit. In an expanded state of the device, the connection point is enclosed by the first support member or arranged at said support member.

    摘要: Prosthetic heart valve apparatus is adapted for delivery into a patient in a circumferentially collapsed condition, followed by circumferential re-expansion at the implant site in the patient. The apparatus includes an annular anchoring structure that can be implanted in the patient first. The apparatus further includes an annular valve support structure, which supports a flexible leaflet structure of the valve. The support and leaflet structures are initially separate from the anchoring structure, but they can be implanted in the patient by interengagement of the support structure with the already-implanted anchoring structure.
