Delivery device having stability tube with compressible region

A transcatheter prosthetic heart valve delivery device comprising:

• an inner shaft assembly including a coupling structure configured to selectively engage a prosthetic heart valve;
• a delivery sheath assembly slidably disposed over the inner shaft assembly;
• an outer stability tube coaxially received over the delivery sheath assembly and having a first portion and a compressible region;
• wherein the compressible region has an axial compressive strength that is less than an axial compressive strength of the first portion;
• and
• a handle assembly maintaining the inner shaft assembly, the delivery sheath assembly, and the outer stability tube, the handle assembly including:
• a housing secured to the inner shaft assembly, and
• an actuator mechanism maintained by the housing and coupled to the delivery sheath assembly, wherein the actuator mechanism is operable to selectively move the delivery sheath assembly relative to the inner shaft assembly.
