摘要:
Apparatus for endovascularly replacing a patient's heart valve, including: a custom-designed anchor; and a replacement valve, wherein the custom-designed anchor is adapted to engage native leaflets of the heart valve, and wherein the anchor and the valve are adapted for in vivo expansion and coupling to one another to form composite apparatus that endovascularly replaces the heart valve. The invention also includes a method for endovascularly replacing a patient's heart valve. In some embodiments the method includes the steps of: providing apparatus comprising an anchor piece and a replacement valve piece; endovascularly delivering the anchor piece to a vicinity of the heart valve in a collapsed delivery configuration; expanding the anchor piece to a deployed configuration; engaging at least one valve leaflet of the heart valve with the anchor piece; endovascularly delivering the replacement valve piece to the vicinity of the heart valve in a collapsed delivery configuration; expanding the replacement valve piece to a deployed configuration; and coupling the valve piece to the anchor piece in vivo to form composite two-piece apparatus that endovascularly replaces the patient's heart valve.

The present invention provides methods and apparatus for endovascularly replacing a patient's heart valve. The apparatus includes a replacement valve and an anchor having an expandable braid. In some embodiments, the expandable braid is fabricated from a single strand of wire. In some embodiments, the expandable braid comprises at least one turn feature. The anchor and the valve preferably are configured for endovascular delivery and deployment.

The invention provides a two-part package and method of use for a pre-attached medical implant and delivery tool system. The package includes a wet compartment and a dry compartment and allows a pre-attached implant and delivery tool system to be at least partially stored immersed in a fluid in the wet compartment and at least partially stored in the dry compartment. In one embodiment the implant comprises a replacement heart valve, and the heart valve is stored inside the wet compartment while the heart valve delivery tool remains dry in the dry compartment.
