Abstract: Apparatus for endovascularly replacing a patient's heart valve, including: a replacement valve adapted to be delivered endovascularly to a vicinity of the heart valve; an expandable anchor adapted to be delivered endovascularly to the vicinity of the heart valve; and a lock mechanism configured to maintain a minimum amount of anchor expansion. The invention also includes a method for endovascularly replacing a patient's heart valve. In some embodiments the method includes the steps of: endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve; expanding the anchor to a deployed configuration; and locking the anchor in the deployed configuration.

Abstract: The present invention provides apparatus for endovascularly replacing a patient's heart valve. The apparatus includes a replacement valve and an expandable anchor configured for endovascular delivery to a vicinity of the patient's heart valve. In some embodiments, the replacement valve is adapted to wrap about the anchor, for example, by everting during endovascular deployment. In some embodiments, the replacement valve is not connected to expandable portions of the anchor. In some embodiments, the anchor is configured for active foreshortening during endovascular deployment. In some embodiments, the anchor includes expandable lip and skirt regions for engaging the patient's heart valve during deployment. In some embodiments, the anchor comprises a braid fabricated from a single strand of wire. In some embodiments, the apparatus includes a lock configured to maintain anchor expansion.

Abstract: A replacement heart valve assembly including an expandable anchor having a skirt region, a lip region, and a groove region therebetween and a replacement valve disposed within the expandable anchor and engaged with the groove region of the expandable anchor.

Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to apparatus for methods for endovascularly replacing a patient's heart valve. The apparatus includes an expandable anchor with leaflet engagement elements on the proximal end of the anchor and a replacement valve. The leaflet engagement elements can be used to prevent distal migration and insure proper positioning of the apparatus.
