A system including a self-expanding prosthesis configured to foreshorten during deployment thereof and a delivery device configured to percutaneously deliver the self-expanding prosthesis. The delivery device includes a handle having an actuator thereon, an outer sheath including a proximal end coupled to the handle and a pusher shaft slidingly disposed within the outer sheath. The pusher shaft has a proximal end coupled to the handle and a distal end configured to releasably couple to the self-expanding prosthesis such that the self-expanding prosthesis axially moves therewith. The inner shaft has a distal portion of the inner shaft that is configured to receive a self-expanding prosthesis thereon. The outer sheath and the pusher shaft are configured to simultaneously move in opposing axial directions via actuation of the actuator on the handle to compensate for the foreshortening of the self-expanding prosthesis during deployment.

A delivery system includes a handle, an inner shaft having a distal portion configured to receive the heart valve prosthesis thereon, a push wire slidingly disposed through a lumen of the inner shaft, and an outer sheath configured to cover the heart valve prosthesis during delivery. A split distal tip or nosecone is attached to a distal end of the inner shaft and includes at least one cutout portion formed through a sidewall thereof. A proximal end of the push wire is operatively coupled to an actuator of the handle and a distal end of the push wire is attached to the cutout portion of the nosecone. When the nosecone is in a delivery configuration the cutout portion is substantially flush with the sidewall of the nosecone. When the nosecone is in a deployed configuration the cutout portion is spaced apart from the sidewall of the nosecone.

Methods and systems for rotationally aligning a commissure of a prosthetic heart valve with a commissure of a native valve are disclosed. In some examples, a delivery apparatus can include a first shaft configured to rotate around a central longitudinal axis of the delivery apparatus, a second shaft extending through the first shaft and having a distal end portion extending distally beyond a distal end portion of the first shaft, an inflatable balloon coupled to the distal end portion of the first shaft, and a third shaft surrounding the first shaft. The first shaft is configured to rotate within the third shaft and translate axially relative to the third shaft, and the third shaft includes a distal tip portion including a plurality of internal helical expansion grooves and a plurality of external helical expansion grooves that are configured to allow the distal tip portion to flex radially outward.

Embodiments of a delivery apparatus for implanting a prosthetic valve are disclosed. The delivery apparatus can include a handle, a first shaft extending from a distal end of the handle, a second shaft extending through a lumen of the first shaft and the handle, and a gripper located proximal to a proximal end of the handle. A proximal end of the second shaft can be connected to the gripper, and the gripper can be axially moveable relative to the handle such that axial movement of the gripper causes corresponding axial movement of the second shaft relative to the first shaft. The gripper can have a bottom surface that is substantially coplanar with a bottom surface of the handle.

A delivery system includes a handle, a guidewire catheter, a nose cone at the distal end of the guidewire catheter that with the guidewire catheter defines an opening concentric with the guidewire catheter, a plurality of wires that extend distally from the handle and essentially parallel with and distributed radially about the guidewire catheter and a stent graft. The wires each extend between a portion of the stents and wall of the stent graft, whereby the stent graft is radially constrained until the wires are retracted. The delivery system can be employed in methods of treating arterial disease, such as aortic aneurysms.

A delivery assembly includes a prosthetic device, a catheter shaft, a release wire, a first line, and a second line. The prosthetic device has a first arm and a second arm. The release wire extends through the catheter shaft. The first line includes a first loop. The first line extends from the catheter shaft, through the first arm of the prosthetic device, and to the release wire, where the release wire extends through the first loop. The second line includes a second loop. The second line extends from the catheter shaft, through the second arm of the prosthetic device, and to the release wire, where the release wire extends through the second loop.

A delivery device includes a control release shaft and a pusher shaft disposed within the control release shaft. A distal end of the control release shaft includes a collar having a sloped distal edge. The control release shaft is rotatable in order to rotate the collar. The pusher shaft has a distal end having a spindle coupled thereto. The spindle is configured to receive at least one connector extending from at least one endmost crown of the self-expanding prosthesis in order to releasably attach the self-expanding prosthesis to the pusher shaft. When disposed over an end of the self-expanding prosthesis, the collar is configured to radially restrain the endmost crowns and the connector of the self-expanding prosthesis. Actuation of an actuator of the delivery device rotates and proximally retracts the collar relative to the spindle to achieve incremental release of the endmost crowns and the connector of the self-expanding prosthesis.

A method of implanting a device in a heart includes inserting an implant into a blood vessel with a delivery apparatus. The implant includes a stent member and an adjustment member. The stent member is circumferentially expandable and contractible. The adjustment member is coupled to the stent member. The delivery apparatus includes a rotatable shaft and a locking mechanism coupled to an end portion of the shaft. The shaft of the delivery apparatus is releasably coupled to the adjustment member of the implant by the locking mechanism of the delivery apparatus. The method further includes positioning the implant at an implantation location within a heart by manipulating the delivery apparatus, and rotating the shaft of the delivery apparatus relative to the stent member of the implant to actuate the adjustment member of the implant. Actuating the adjustment member results in circumferential expansion or contraction of the stent member.

A conveyor and a lumen apparatus delivery system. The conveyor includes a sheath core tube, a delivery sheath and an operating handle. The proximal end of the sheath core tube and the proximal end of the delivery sheath are both connected to the operating handle. The delivery sheath and the sheath core tube are both a hollow tube. The delivery sheath is sleeved on the sheath core tube in an axially slidable manner, and the delivery sheath and the sheath core tube cooperatively define a storable cavity. The delivery sheath includes a loading portion, a pushing portion and a connecting portion. The proximal end of the loading portion is connected to the distal end of the pushing portion; the proximal end of the pushing portion is connected to the distal end of the connecting portion, and the proximal end of the connecting portion is connected to the operating handle.

A delivery apparatus for an implantable medical device includes a handle, a shaft having a proximal end portion and a distal end portion, the proximal end portion being coupled to the handle, and a nosecone coupled to the distal end portion of the shaft. The nosecone includes a proximal end portion and a distal end portion pivotably coupled to the proximal end portion.
