摘要： Systems and methods for delivery a medical device to a heart valve annulus are disclosed. A method of delivering a medical device to a heart valve annulus includes: (1) aligning a first imaging sensor such that a view of the first imaging sensor is along a primary plane of the heart valve annulus; (2) aligning a second imaging sensor such that a view of the second imaging sensor is along a longitudinal axis of the heart valve annulus; (3) attaching a delivery system holding the medical device to a delivery arm; (4) adjusting the delivery arm to set an angle of the delivery system perpendicular to the primary plane using images from the first imaging sensor; (5) adjusting the delivery arm to center the delivery device in the heart valve annulus using images from the second imaging sensor; and (6) deploying the medical device into the heart valve annulus.

摘要： Apparatus and methods are described herein for use in the transfemoral delivery and deployment of a prosthetic mitral valve. In some embodiments, a method includes inverting an outer frame of a prosthetic mitral valve when in a biased expanded configuration. After inverting the outer frame, the prosthetic mitral valve is inserted into a lumen of a delivery sheath such that the mitral valve is moved to a collapsed configuration. The delivery sheath is inserted into a femoral vein and moved through the femoral vein and a septum of a heart until a distal end of the delivery sheath is disposed in the left atrium of the heart. The prosthetic mitral valve is moved distally out of the delivery sheath such that the inverted outer frame reverts and the prosthetic mitral valve assumes its biased expanded configuration. The prosthetic mitral valve is then positioned within a mitral annulus of the heart.

摘要： A loading assembly for crimping and loading a prosthetic heart valve into a delivery device includes a loading base, a base funnel, and a compression member. The loading base has a support and a body extending from the support with a recess defined within the body. The recess is configured to receive a substantial portion of the annulus section of the heart valve in an at least partially collapsed condition. The base funnel is configured to be coupled to the loading base and to at least partially collapse the annulus section of the heart valve as it is inserted into the recess in the loading base. The compression member is configured to be coupled to the loading base with the heart valve inserted in the recess for further collapsing the heart valve and loading it into the delivery device.

摘要： A support structure for a formwork panel having a support structure and a formwork skin positioned on the front of the support structure and attached to the support structure, wherein the support structure has at least one edge girder on a pair of opposite edges and a plurality of transverse girders between these two edge girders which run transversely to these two edge girders, characterized in that at least some of the transverse girders are designed as a profile girder, comprising a flange at its first end arranged at the front of the support structure, a tubular hollow section at its second end away from the front of the support structure, and between them a preferably wall-like member connecting the first end and the second end.

摘要： A prosthetic heart valve is provided with a cuff having features which promote sealing with the native tissues even where the native tissues are irregular. The cuff may include a portion adapted to bear on the LVOT when the valve is implanted in a native aortic valve. The valve may include elements for biasing the cuff outwardly with respect to the stent body when the stent body is in an expanded condition. The cuff may have portions of different thickness distributed around the circumference of the valve in a pattern matching the shape of the opening defined by the native tissue. All or part of the cuff may be movable relative to the stent during implantation.

摘要： An adjustable length strut includes two joints, a threaded rod extending between the joints, and a tube adapted to receive the threaded rod. An actuation mechanism with gear teeth extending radially outward of the strut axis is rotatably fixed to the threaded rod. A protrusion may be coupled to an end of the threaded rod by a rotatable collar, with the protrusion extending through a slot in the tube to mark the length of the strut. A modular attachment member may be adapted to be couple to the first joint and include a worm gear adapted to engage gear teeth of the actuation mechanism. The modular attachment member may include a radiofrequency identity tag mechanism adapted to be read by a tag reader of a tool, the tool adapted to couple to the attachment member to rotate the worm gear to increase or decrease the effective length of the strut.

摘要： A prosthetic heart valve can include an outer support assembly, an inner valve assembly, which define between them an annular space, and a pocket closure that bounds the annular space to form a pocket in which thrombus can be formed and retained. Alternatively, or additionally, the outer support assembly and the inner valve assembly can be coupled at the ventricle ends of the outer support assembly and the inner valve assembly, with the outer support assembly being relatively more compliant in hoop compression in a central, annulus portion than at the ventricle end, so that the prosthetic valve can seat securely in the annulus while imposing minimal loads on the inner valve assembly that could degrade the performance of the valve leaflets.

摘要： A prosthetic heart valve may include a stent, a valve assembly disposed within the stent, a flange, and a plurality of anchor arms coupled to the stent. The stent may have collapsed and expanded conditions and inflow and outflow ends. The flange may include a plurality of braided wires and may be coupled to the stent and may be positioned adjacent the inflow end of the stent in the expanded condition of the stent. Each anchor arm may have a first end coupled to the stent adjacent the outflow end of the stent, a second end coupled to the stent adjacent the outflow end of the stent, and center portions extending from the first and second ends toward the inflow end of the stent. The center portions may be joined together to form a tip pointing toward the inflow end of the stent in the expanded condition of the stent.

摘要： A delivery device 100 includes a catheter assembly 120 and an operating handle 130. The operating handle 130 may include a nose 131 affixed to the catheter assembly 120, an axial shaft 180, a base 132 translationally fixed to a proximal end of the axial shaft, a screw 160 having external threads and a non-circular lumen 161, the axial shaft extending through the non-circular lumen, a proximal end 171 of a pull wire 170 being affixed to the screw, a knob 150 having internal threads engaged with the external threads of the screw, and a collar 140 extending at least partially around the axial shaft. When the collar 140 is in a proximal position, rotation of the knob 150 may deflect the distal end 121 of the catheter assembly 120. When the collar is in a distal position, rotation of the knob 150 may rotate the catheter assembly 120.
