Abstract

A delivery device is configured for aligning and stabilizing a prosthetic heart valve for deployment in a native heart valve annulus. The device includes a catheter assembly having an inner shaft around which a valve compartment is defined, an outer shaft assembled over the inner shaft and adapted to slide relative to the inner shaft, a distal sheath connected to a distal end of the outer shaft and slidable therewith, an outer tube assembled over the outer shaft, and an alignment and stabilization device having a collapsed condition and an expanded condition. The outer tube is adapted to slide relative to the outer shaft to selectively cover and uncover the alignment and stabilization device.
