Abstract
Devices, systems and methods are described herein to provide improved steerability for delivering a prosthesis to a body location, for example, for delivering a replacement valve to a native valve location in a heart. Disclosed are a number of features that can improve steerability or release of the prosthesis into the body location. In one preferred delivery system, a proximal handle can be manipulated to apply tension to a pair of diametrically opposed axial runner wires extending through lumens in a wall of a flexible tubular shaft. By applying tension to a pair of axial runner wires, the tubular shaft can be stiffened along a plane extending substantially through the pair of axial runner wires, while the shaft is permitted to freely bend in a perpendicular plane. This feature advantageously provides the ability to adjust the steerability and flexibility of a tubular shaft to meet the requirements of a particular procedure.
