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.

Multi-step deployment to improve TAVR implant stability

A prosthetic heart valve may include a collapsible and expandable stent, a cuff attached to an annulus section of the stent, and a plurality of leaflets attached to at least one of the cuff or the stent within an interior region of the stent. The stent may have a plurality of cells connected to one another in a plurality of annular rows around the stent. The leaflets together may have a coapted position occluding the interior region of the stent and an open position in which the interior region is not occluded. Each leaflet may include a flat mesh of braided wire material having a plurality of pores extending therethrough. The leaflets may be devoid of biological material at a time of implantation.
