A prosthetic implant delivery assembly includes a prosthetic implant and a catheter. The prosthetic implant includes a plurality of apices with apertures. Each apex of the plurality of apices is circumferentially-spaced apart relative to an adjacent apex. The catheter includes a plurality of arms and a plurality of locking elements. Each of the arms includes an opening configured to receive a respective apex of the prosthetic implant. Each of the locking elements is configured to extend through the aperture of a respective apex of the prosthetic implant. A length of at least one of the locking elements is different than a length of another locking element such that when the prosthetic implant is coupled to the catheter by the locking elements, a longitudinal axis of the prosthetic implant can be held at a tilted position relative to a longitudinal axis of the catheter.

Methods for controlled heart valve delivery

Certain embodiments of the present disclosure provide a prosthetic valve (e.g., prosthetic heart valve) and a valve delivery apparatus for delivery of the prosthetic valve to a native valve site via the human vasculature. The delivery apparatus is particularly suited for advancing a prosthetic heart valve through the aorta (i.e., in a retrograde approach) for replacing a diseased native aortic valve. The delivery apparatus in particular embodiments is configured to deploy a prosthetic valve from a delivery sheath in a precise and controlled manner at the target location within the body.

Prosthetic heart valve delivery apparatus

In a particular embodiment, the present disclosure provides a prosthetic valve delivery assembly that includes a storage tube and a nose cone cap. A prosthetic valve having a frame is at least partially disposed within the storage tube. A nose cone is disposed about an elongated shaft. The nose cone cap and the storage tube have mating first and second locking member that can be coupled to selectively secure the nose cone cap to the storage tube.

Storage assembly for prosthetic valve

Valve repair devices and systems configured to detect proper valve leaflet insertion. The device/system can have a pair of paddles and a clasp attached to each of the paddles. The clasps may have a fixed arm attached to the paddle, a movable arm connected to the fixed arm that is movable between an open position and a closed position, and an indicator arm connected to at least one of the fixed arm and the movable arm. The indicator arm can move between a first position when not engaged with a leaflet and a second, engaged position when engaged with the leaflet. Movement of the indicator arm from the first position to the second, engaged position indicates capture of a leaflet of the native valve by the pair of paddles.

Heart valve sealing devices and delivery devices therefor

An implantable prosthetic device has a coaption element and at least one anchor. The coaption element is configured to be positioned within the native heart valve orifice to help fill a space where the native valve is regurgitant and form a more effective seal. The coaption element can have a structure that is impervious to blood. The coaption element can be connected to leaflets of the native valve by the anchor.

Valve repair devices for repairing a native valve of a patient

A handle for a prosthetic heart valve delivery apparatus includes a housing, a motorized mechanism, and a holding mechanism. The housing is configured to be hand-held by a user and includes a distal opening. The motorized mechanism is disposed within the housing and is configured to be releasably coupled to a proximal end portion of a first shaft of the prosthetic heart valve delivery apparatus. When actuated, the motorized mechanism is configured to rotate the first shaft relative to the housing. The holding mechanism is disposed inside the housing and is configured to engage a proximal end portion of a second shaft of the prosthetic heart valve delivery apparatus such that the second shaft is axially and rotationally fixed relative to the housing, and the first shaft extends through the second shaft.

In a particular embodiment, the present disclosure provides a prosthetic valve delivery assembly that includes a storage tube. A prosthetic valve having a frame is at least partially disposed within the storage tube. A nose cone is disposed about an elongated shaft. A stylet having at least a first bent portion extends through a lumen of the nose cone. The at least a first bent portion is disposed within the lumen of the nose cone and restricts axial movement of the elongated shaft relative to the prosthetic valve.

A prosthetic heart valve delivery system can include a catheter portion having a sheath that can cover and uncover the prosthetic heart valve mounted on an inner shaft, a handle having a sheath actuator operatively coupled to a proximal portion of the sheath, the inner shaft extending through the handle, and a shaft retractor releasably coupled to a proximal portion of the handle and fixedly coupled to a proximal portion of the inner shaft. A sheath actuator can move the sheath axially relative to the inner shaft when the shaft retractor is coupled to the handle, and a proximal movement of the sheath relative to the inner shaft can cause the sheath to uncover the prosthetic heart valve. The shaft retractor can be operable to retract the inner shaft and the nosecone proximally relative to the sheath when the shaft retractor is released from the handle.

One method of implanting a prosthetic valve includes advancing the valve into a patient with a delivery apparatus. The valve includes apices circumferentially-spaced apart relative to each other. At least some of the apices include first apertures. The delivery apparatus includes release arms and a sheath. The release arms include second apertures for receiving the apices. At least one of the second apertures of the release arms has a different length than another one of the second apertures. The method also includes positioning the valve at a location, retracting a sheath of the delivery apparatus relative to the valve, allowing the valve to self-expand from a radially compressed state to a radially expanded state, and while the valve is coupled to the delivery apparatus, pivoting the valve relative about the release arms such that an axis of the valve is tilted relative to an axis of the delivery apparatus.

In a particular embodiment, the present disclosure provides a prosthetic valve delivery assembly that includes a storage tube. A prosthetic valve having a frame is at least partially disposed within the storage tube. A nose cone is located distally to the valve. A removable tab is disposed between the distal end of the frame and the nose cone. The tab assists in maintaining the position of the nose cone relative to the distal end of the frame.

A prosthetic implant delivery assembly can include a prosthetic implant and an elongate catheter. The prosthetic implant can include an expandable stent portion having a longitudinal axis extending from a first end portion of the stent to a second end portion of the stent. The catheter can include a longitudinal axis extending from a proximal end portion of the catheter to a distal end portion of the catheter and a plurality of arms extending axially from the distal end of the catheter. The first end portion of the stent can be releasably and pivotably coupled to at least one the arms of the catheter such that the stent can pivot about the at least one of the arms so that the longitudinal axis of the stent is tilted relative to the longitudinal axis of the catheter.

Apparatus for controlled heart valve delivery

A method of implanting a prosthetic mitral valve assembly is disclosed. The prosthetic mitral valve assembly includes a stent and valve combination. The prosthetic mitral valve assembly is provided with an anchoring portion adapted to be positioned in the left atrium. In one embodiment, the anchoring portion includes at least one anchoring arm sized for placement in a pulmonary vein. The stent is radially expandable so that it can expand into position against the walls of the left atrium and accommodate a wide range of anatomies. Contact between the stent and the native tissue in the left atrium reduces paravalvular leakage and prevents migration of the stent once in place.

Method of implanting a prosthetic valve in a mitral valve with pulmonary vein anchoring

An apparatus for treating a mitral valve, comprising an elongate member having a spiral shape, the elongate member having a proximal end portion and a distal end portion, an expandable proximal anchor joined to the proximal end portion of the elongate body, and an expandable distal anchor joined to the distal end portion of the elongate body. The elongate member is configured to adjust from an elongated state to a shortened state after delivery at least partially into a coronary sinus for reshaping a mitral annulus.
