Abstract: A transcatheter valve prosthesis includes an expandable tubular stent, a prosthetic valve within the stent, and an anti-paravalvular leakage component coupled to and encircling the tubular stent. The anti-paravalvular leakage component includes a radially-compressible annular scaffold, which is a sinusoidal patterned ring of self-expanding material, and an impermeable membrane extending over the annular scaffold. The anti-paravalvular leakage component has an expanded configuration in which at least segments of the annular scaffold curve radially away from the tubular stent. Alternatively, the anti-paravalvular leakage component includes a plurality of self-expanding segments and an annular sealing element coupled to inner surfaces of the segments. The anti-paravalvular leakage component has an expanded configuration in which the segments curve radially away from the tubular stent and the annular sealing element is positioned between an outer surface of the tubular stent and inner surfaces of the segments. The segments may be orthogonal or oblique to the outer surface of the tubular stent.

Abstract: This material comprises an annuloplasty member able to be introduced using a catheter through minimally invasive vascular access, then to be delivered by said catheter and fixed to the valve annulus. According to the invention, it includes at least one catheter comprising at least one guide member able to be deployed from said catheter such that it extends along one portion of the valve annulus of the valve, in the immediate proximity of said valve annulus, and an implant having a helical shape engaged on said guide member, connected, with separation possibility, to actuation means making it possible to cause this implant to move forward while driving it in rotation around its axis; the implant can thus be deployed from the catheter while being simultaneously moved forward and driven in rotation along its axis.

Abstract: A catheter that comprises a sheath that is connected at opposing ends to concentric tubes that move relative to each other in a manner that alternatively covers and exposes a medical device loaded onto the catheter. A portion of the sheath is arranged so as to invert upon itself so that axial movement of one tube relative to the other simultaneously moves the inversion point over or away from the device, alternatively covering or exposing the device.

Abstract: A visualization device for use with a loading tray includes a frame comprising a floor, a first side wall extending generally perpendicular from the floor, and a second side wall extending generally perpendicular from the floor and spaced from the first side wall. The visualization device further includes a mirror abutting the floor of the frame. A magnifying glass may also be supported by top edges of the first and second side walls, or by runners coupled to the top edges of the first and second side walls. The visualization device may be slideably disposed in a reservoir of a loading tray.

Abstract: Heart valve prostheses are provided having a self-expanding frame that supports a valve body comprising a skirt and a plurality of coapting leaflets. The leaflets are constructed with four commissure points to reduce the stress and strain applied to the commissure points and to efficiently distribute and transmit forces along the leaflets and to the frame.

Abstract: A medical device delivery system can include a dilator including a tip having a taper in a distal direction, a coupler, and a flap that radially protrudes from the tip. The flap can be configured to bend against a body lumen to cover at least a portion of the delivery system when the dilator is tracked through the body lumen. A medical device delivery system can include a dilator including a tip having a lumen and a coupler having a lumen. The coupler can be configured to securely connect to the tip such that the lumen of the tip is aligned with the lumen of the coupler to allow a guide wire to pass therethrough. Methods for loading a medical device into a delivery catheter are also disclosed.

Abstract: An implantable prosthetic valve assembly includes a radially expandable frame including an inflow portion and a second portion. The inflow portion is configured, in an expanded state, to bear against a native cardiac annulus in a manner so as to resist migration. The second portion extends from the inflow zone in an outflow direction, and is configured, in an expanded state, not to bear against the native cardiac annulus and an ascending aorta. The valve assembly also includes a prosthetic valve coupled to the frame substantially within the second portion.
