1. A method comprising:
moving a housing of a delivery capsule carrying a prosthetic heart valve from a containment configuration to a deployed configuration while the delivery capsule is positioned at a native heart valve, wherein the movement of the housing is such that the prosthetic heart valve self-expands and releases from the delivery capsule, wherein the delivery capsule is carried by a distal portion of an elongated body;
expanding an expandable atraumatic member from a compacted configuration in which the atraumatic member has a first diameter to an expanded configuration in which the expandable atraumatic member has a second diameter greater than the first diameter such that a peripheral portion of the atraumatic member extends laterally outward relative to a proximal rim of the housing, wherein with the expandable atraumatic member in the expanded configuration and the housing in the deployed configuration, the expandable atraumatic member is disposed adjacent the proximal rim of the housing; and
withdrawing the delivery capsule and the expandable atraumatic member in a proximal direction relative to the prosthetic heart valve with the expandable atraumatic member in the expanded configuration,
wherein the expandable atraumatic member includes an atraumatic surface disposed opposite the proximal rim of the housing with the housing in the deployed configuration and the expandable atraumatic member in the expanded configuration,
wherein the atraumatic surface is an inclined surface that flares outwardly in a distal direction.
