A transcatheter valve prosthesis including a tubular stent, a prosthetic valve component disposed within and secured to the stent, and a centering mechanism coupled to and encircling an outer surface of the tubular stent. The centering mechanism includes a self-expanding centering ring having an expanded diameter in the expanded configuration that is greater than an expanded diameter of the tubular stent in the expanded configuration and a plurality of self-expanding spokes radially extending between the tubular stent and the centering ring. The centering mechanism may include a base ring and/or a skirt. Alternatively, the centering mechanism includes a plurality of self-expanding loops. When each loop is in a delivery configuration the loop has a straightened profile that proximally extends from a proximal end of the tubular stent. When each loop is in an expanded configuration the loop has a U-shaped profile radially spaced apart from the tubular stent.

Valve prostheses having an integral centering mechanism and methods of use thereof

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.

Delivery system having an integral centering mechanism for positioning a valve prosthesis in situ

An elastic percutaneous elastic introducer sheath is disclosed which can locally expand and reduce to accommodate a transcatheter medical device. The elastic introducer sheath includes a non-circumferentially continuous elastic frame, a liner, and a jacket.
