摘要： A medical device delivery system includes a steering catheter including a first steering ring having a plurality of apertures positioned in the wall of the first steering ring. The plurality of apertures are positioned at spaced distances around a circumference of the first steering ring. A first steering cable passes through a first one of the apertures, and a first return cable passes through a second one of the apertures. A second steering cable passes through a third one of the apertures, and a second return cable passes through a fourth one of the apertures. The first steering cable is positioned about 180 degrees from the second steering cable. A handle is operably coupled to a proximal end of the steering catheter. A first control member controls the first steering and first return cable, and a second control member controls the second steering and second return cable.

摘要： A tubular instrument includes a tubular assembly having first and second handling tubes extending from a proximal operating area to a distal functional area, a radially self-expanding wire structure, and a holding device. The first and second handling tubes are rotatable relative to each other. A control interface is provided at the proximal operating area for the relative rotational motion actuation of the first and second handling tubes. The holding device includes a first connecting unit and a second connecting unit. The first connecting unit includes a first filament connecting unit having a first connecting filament fixed to a first structural connection interface of the wire structure and to a tube connection interface of the first handling tube and extends therebetween with a radial directional component, and which winds onto or unwinds from the first handling tube upon rotation of the first and second handling tubes.

摘要： A system for heart valve repair includes a packaging assembly for storing the replacement heart valve. The packaging assembly includes a valve support having a base for holding the replacement heart valve, a ring positioned within the valve support and configured to fit around a circumference of the replacement heart valve, and a retention mechanism. The retention mechanism includes a cap and plurality of sutures configured to be attached to the cap and to the replacement heart. The packaging assembly having a locked configuration in which the ring and the valve support are locked together and the sutures tension the replacement heart valve. The packaging assembly is designed to hold and transport a replacement heart valve and fits within a shipment jar.

摘要： A method of delivering a prosthetic mitral valve includes delivering a distal anchor from a delivery sheath such that the distal anchor self-expands inside a first heart chamber on a first side of the mitral valve annulus, pulling proximally on the distal anchor such that the distal anchor self-aligns within the mitral valve annulus and the distal anchor rests against tissue of the ventricular heart chamber, and delivering a proximal anchor from the delivery sheath to a second heart chamber on a second side of the mitral valve annulus such that the proximal anchor self-expands and moves towards the distal anchor to rest against tissue of the second heart chamber. The self-expansion of the proximal anchor captures tissue of the mitral valve annulus therebetween.

摘要： A loading device for crimping a prosthetic heart valve without an internal support member includes a cone having a cone body with a tapering diameter and defining a lumen therethrough and a cone base extending radially from the cone body. The cone base may couple to a funnel also having a tapering diameter and defining a lumen therethrough. The cone may be coupled to the funnel such that the lumen of the cone is aligned with the lumen of the funnel along a longitudinal axis of the loading device. The cone body may define a plurality of slots configured to receive the tines extending from the prosthetic heart valve as the valve is pulled through the loading device and compressed from an expanded state to a collapsed state by the tapering diameter of the cone and the funnel to be disposed inside a delivery device.

摘要： A prosthetic heart valve system includes a collapsible and expandable outer frame extending from an atrial end to a ventricular end, the atrial and ventricular ends coupled by a central portion, the outer frame including a plurality of suture receiving rings formed around a circumference of the ventricular end. The system further includes a collapsible and expandable inner frame positioned radially inward of and coupled to the outer frame. The system further includes a prosthetic valve assembly coupled to, and positioned radially inward of, the inner frame, and a strand extending from a first free end to a second free end. A middle portion of the strand passes through each of the suture receiving rings in a delivery configuration of the prosthetic heart valve system. The first and second free ends are configured to be pulled simultaneously by a user to radially collapse the ventricular end of the outer frame.

摘要： An intravascular delivery system includes a delivery sheath capable of transmitting a predetermined tension or compression force in a longitudinal direction while maintaining flexibility to navigate tortuous anatomy. A method of delivering a medical device includes inserting an intravascular device delivery system including a delivery sheath having a continuous spine into a bodily lumen. A distal longitudinal force is applied to the delivery sheath. The distal force is transmitted through the continuous spine and across one or more slit cuts of the delivery sheath. A proximal longitudinal force is applied to the delivery sheath. The proximal longitudinal force is transmitted through the continuous spine of the delivery sheath.

摘要： A delivery device includes a central elongate structure, a sheath, a plurality of tethers extending through the central elongate structure configured to hold a cardiac valve, a cutting mechanism, a handle, and a control. The sheath is configured to slide over the central elongate structure. The cutting mechanism is configured to cut the tethers upon activation to release the cardiac valve. The handle is connected to the central elongate structure. The control on the handle is configured to activate the cutting mechanism.

摘要： A prosthetic mitral valve includes an anchor assembly, a strut frame, and a plurality of replacement leaflets secured to the annular strut frame. The anchor assembly includes a ventricular anchor, an atrial anchor, and a central portion therebetween. The ventricular anchor and the atrial anchor are configured to flare radially outwards relative to the central portion. The annular strut frame is disposed radially within the anchor assembly and is attached to the anchor assembly. The central portion is configured to align with a native valve orifice and the ventricular anchor and the atrial anchor are configured to compress native cardiac tissue therebetween.
