    Abstract: A guidewire system may include a guidewire having a relatively stiff proximal section and a relatively flexible distal section joined by a transition region, and a TAVI device slidably disposed on the guidewire. The guidewire may include an expandable element disposed about the transition region. The expandable element may be configured to expand from a collapsed configuration to an expanded configuration. The guidewire may include an expandable element disposed at the distal end. The distal section may be pre-configured to form more than one distal loop. A method of protecting an apex of a left ventricle during a TAVI procedure may include inserting a guidewire into the left ventricle, positioning a transition region adjacent the apex, expanding an expandable element such that the expandable element spans the apex, advancing a TAVI device distally over the guidewire to an aortic valve, and performing a TAVI procedure at the aortic valve.

    Abstract translation: 导丝系统可以包括具有相对刚性的近端部分和由过渡区域连接的相对柔性的远侧部分的导丝，以及可滑动地设置在导丝上的TAVI装置。 引导线可以包括围绕过渡区域设置的可扩张元件。 可扩展元件可以被配置为从折叠构型扩展到扩展构型。 引导线可以包括设置在远端处的可扩张元件。 远侧部分可以预先配置成形成多于一个远端环。 在TAVI程序期间保护左心室顶点的方法可包括将导线插入左心室，将过渡区域定位在邻近顶点的位置，使可扩张元件膨胀使得可扩张元件跨越顶点，使TAVI器件向远端延伸 在导丝上穿过主动脉瓣，并在主动脉瓣上执行TAVI程序。

    Abstract: An apparatus for endovascularly replacing a patient's heart valve comprises an anchor having an outer surface and an inner surface. The anchor is expandable from a collapsed delivery configuration to a fully deployed configuration. A first locking element and a second locking element are attached to the inner surface of the anchor. The first locking element is engageable with the second locking element. At least one of the first locking element and the second locking element has a curved outer surface. Methods for attaching the second locking element to the anchor are also provided.
