Abstract
Embodiments hereof relate to a delivery system for a transcatheter valve prosthesis, the delivery system having an integral centering mechanism to circumferentially center both the delivery system and the valve prosthesis within a vessel at the target implantation site. The centering mechanism may include expandable wings that may be selectively aligned with openings formed through a sidewall of an outer shaft of the delivery system, a coiled wing that may be selectively exposed through an opening formed through a sidewall of an outer shaft of the delivery system, a plurality of elongated filaments extending through a plurality of lumens of an outermost shaft of the delivery system that may be selectively deployed or expanded, an outer shaft that includes at least one pre-formed deflection segment formed thereon, a tool having a deployable lever arm, and/or a plurality of loops deployable via simultaneous longitudinal and rotational movement.
