Delivery devices for delivering a self-expanding prosthetic heart valve are disclosed. The delivery device includes at least one cord is configured to selectively cinch the self-expanding prosthetic heart valve. The delivery device further includes at least one self-expanding release pin comprising a proximal segment, a distal segment, and an intermediate segment positioned between the proximal segment and the distal segment. The at least one self-expanding release pin includes a normal, expanded condition wherein the intermediate segment extends radially outward relative to a central axis of the spindle from the proximal segment to the distal segment. The delivery device further includes a capsule configured to be distally extended relative to the spindle to collapse the at least one self-expanding release pin from the normal, expanded condition of the at least one self-expanding release pin to a collapsed condition of the at least one self-expanding release pin.

Delivery devices for delivering a self-expanding prosthetic heart valve

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

A system for replacing a heart valve of a patient. The system includes a delivery device and a prosthetic heart valve. The system is configured to be transitionable between a loaded state, a partially deployed state and a deployed state. In the loaded state, the prosthetic heart valve engages a coupling structure and is compressively retained within a primary capsule, which constrains the prosthetic heart valve in a compressed arrangement. In the partially deployed state, the prosthetic heart valve engages the coupling structure and is compressively retained within a secondary capsule, which constrains the prosthetic heart valve to a partially deployed arrangement. The partially deployed arrangement is less compressed than the compressed arrangement and less expanded than a deployed arrangement. In the deployed state, the primary and secondary capsules are retracted from over the prosthetic heart valve, which expands to the deployed arrangement and is released from the coupling structure.

System and method of stepped deployment of prosthetic heart valve

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.

Anti-paravalvular leakage component for a transcatheter valve prosthesis

Stented prosthetic heart valves comprising a stent frame having a compressed arrangement for delivery within a patient's vasculature and an expanded arrangement for deployment within a native heart valve. The stented prosthetic heart valves including a paravalvular leakage prevention or mitigation wrap that encircles a stent frame and is formed of a flexible material having a variable diameter defined by a greatest distance between the wrap and the stent frame. The wrap further includes a first end coupled to the stent frame and an opposing second end that is not coupled to the stent frame, wherein the wrap can selectively enlarge its diameter in situ via movement of the second end. Devices for and methods of selectively deploying the wrap are also disclosed.

Stented prosthetic heart valve having a wrap and delivery devices

Stented prosthetic heart valves including a stent frame having a plurality of stent frame support structures collectively defining an interior surface, an exterior surface and a plurality of cells. The stented prosthetic heart valve further including a valve structure including valve leaflets disposed within and secured to the stent frame and defining a margin of attachment. The stented prosthetic heart valve including one or both of an outer paravalvular leakage prevention wrap and an inner skirt for supporting the valve leaflets. In various embodiments, the outer wrap is positioned entirely on one side of the margin of attachment. In embodiments including an inner skirt, the outer wrap and the inner skirt are on opposite sides of the margin of attachment such that the inner skirt and the outer wrap do not overlap. In other embodiments, the outer wrap includes a plurality of zones having varying thickness.

Stented prosthetic heart valve having a paravalvular sealing wrap

Aspects of the disclosure relate to devices and methods for preparing an existing, implanted prosthetic aortic valve for subsequent prosthetic aortic valve implantation. To prepare the existing valve, a valve preparation device is delivered to the valve and valve leaflets are severed either via mechanical cutting or electrodes so that the leaflets cannot obstruct a blood flow path once a prosthetic valve is subsequently implanted within the valve. Similarly, in alternate embodiments, devices and methods of the disclosure can be used for preparing a native aortic valve for delivery and implantation of a prosthetic valve.

Devices and methods for aortic valve preparation prior to transcatheter prosthetic valve procedures

Delivery devices for a stented prosthetic heart valve. The delivery device includes a spindle, at least one cord, and a lateral control feature. The cord is tensioned to crimp the prosthesis to a compressed condition for delivery to a target site. Tension is lessened to allow the prosthesis to self-expand. In a tethered and expanded state in which the prosthesis has self-expanded and is connected to the spindle by the cord, the lateral control feature directs the spindle to a prescribed location relative to the prosthesis appropriate for a functional evaluation of the prosthesis. In some embodiments, the spindle is directed to a center of the prosthesis; in other embodiments, the spindle is held at a commissure of the prosthesis. The lateral control features of the present disclosure assume numerous forms.

Transcatheter prosthetic heart valve delivery system with lateral offset control

A system for percutaneous delivery of a stented prosthetic heart valve. The system includes a delivery device with a self-expanding prosthetic heart valve attached thereto and a delivery sheath with an opening on a distal end thereof. The delivery sheath includes a funnel on a proximal end thereof. The delivery device is inserted into the funnel of the delivery sheath. As the delivery device is advanced into the funnel, the expanded heart valve is compressed by the shape of the funnel into a crimped arrangement. The delivery device further advances the heart valve distally within the delivery sheath past the delivery sheath opening. The delivery device is advanced relative to the delivery sheath in transitioning the heart valve from a crimped arrangement to the expanded and deployed arrangement.

Transcatheter prosthetic heart valve delivery system and method

The disclosure includes methods, systems and devices for severing and optionally removing at least a portion of heart valve leaflets. Leaflets can be partially removed or entirely removed or otherwise, the leaflets can be severed or splayed in such a way as to avoid coronary blockage, LVOT obstruction, or access challenges in procedures where a prosthetic valve is to be implanted within a previously implanted prosthetic valve. The disclosure also relates to numerous devices for and methods of disabling one or more valve ligating devices to provide an unobstructed valve opening so that a prosthetic heart valve can be implanted within the opening. The ligation device(s) is disabled either by removing the ligation device(s) or severing one leaflet so that ligated leaflets can be separated. In some embodiments, the ligation device(s) are severed to disable the ligation device(s).
