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.

Abstract: An indicator system includes a human perceptible indicator, a motion-activated switch, and a controller in electrical communication with the indicator and the motion activated switch. The controller includes a non-transitory memory storing first and second indicator sequences, and a counter counting a number of activations of the motion-activated switch. The controller causes activation of the indicator according to the first indicator sequence when the number of switch activations is less than a first threshold count, and according to the second indicator sequence when the number of switch activations is greater than or equal to the first threshold count, and less than a second threshold count.
