摘要： Prosthetic heart valve devices with tethered anchors and associated systems and methods are disclosed herein. A heart valve device configured in accordance with embodiments of the present technology can include, for example, a valve support for carrying a prosthetic valve. The valve support can be configured to be implanted at an annulus of a native mitral valve. The device can further include at least one elongated flexible member extending from the valve support in a ventricular direction, and an anchor coupled to the valve support via the elongated flexible member. The anchor can be shaped to wrap around an exterior area of an apical portion of the heart. In addition, the anchor can inhibit retrograde migration of the valve support.

摘要： Methods, systems, devices and apparatuses to support the walls of one or more blood vessels and perfuse blood through the one or more blood vessels. The stent device allows perfusion through one or more vessels. The stent device includes a tubular member. The tubular member has a single body that includes a main body lumen, a bypass lumen and one or more branch lumens. The tubular member is configured to be inserted into the aorta. The main body lumen is configured to expand and support a vessel wall of the aorta and the one or more branch lumens are configured to connect to one or more extension grafts that extend within one or more branch vessels. The stent device includes multiple rings of stents. The multiple rings of stents are positioned within the tubular member and are configured to be expandable to expand the tubular member to support the tubular member against the vessel walls.

摘要： A prosthetic valve including an inner frame, an outer frame, and a connection assembly interconnecting the frames. The inner frame defines an interior volume for receiving a valve structure within the interior volume. The outer frame surrounds the inner frame. The inner and outer frames are each configured to be transitionable between compressed and expanded conditions. The prosthetic heart valve provides a initial deployed state in which the inner and outer frames are in the expanded condition, and a radial shape of the outer frame is adjustable via the connection assembly to a final deployed state. A shape of the outer frame can be adjusted upon implant to enable radial anchoring at the native annulus, while addressing possible non-uniformities of the native annulus and possible anatomical concerns such as LVOT obstruction.

摘要： In some examples, a tissue compression device includes a base including a major surface configured to engage a dorsal surface of a hand of a patient, a flexible backing adjustably mechanically connected to the base and configured to engage a palmar surface of the hand when the dorsal surface of the hand is engaged with the base, and an expandable member mechanically connected to the flexible backing. The expandable member is configured to be positioned over an ulnar region of the patient when the palmar surface of the hand is engaged with the flexible backing and the dorsal surface of the hand is engaged with the base, such that inflation of the expandable member may apply pressure to tissue near the ulnar artery of the patient.

摘要： An introducer sheath system including an outer layer, an inner layer, and a dilator is disclosed. The outer layer is circumferentially extending between a first longitudinal edge and a second longitudinal edge. An expandable gap is defined between the first and second longitudinal edges. The inner layer is disposed within the outer layer. The inner layer is configured to be continuously circumferentially expandable. The inner layer includes a non-extended state having a circumferential portion extending circumferentially inside the outer layer and a fold portion extending into an interior cavity of the inner layer. The inner layer includes an extended state wherein the fold portion extends at least partially circumferentially between the first and second longitudinal edges. The dilator is extendable longitudinally within the inner layer. The dilator includes a recess configured to accommodate the fold portion of the inner layer.

摘要： A delivery device for percutaneously delivering a stented prosthetic heart includes a sheath, a handle, and adjustment device including a fine adjustment mechanism, and an outer stability shaft. The sheath defines a lumen and is configured to compressively constrain the stented prosthetic heart valve. The handle is coupled to the proximal portion of the sheath and includes an actuator mechanism coupled to a proximal portion of the sheath that is configured to selectively move the sheath relative to the housing to release the stented prosthetic heat valve. The adjustment device is coupled to the handle and includes an adjustment lumen through which the sheath and the handle slidably extend. The outer stability shaft is coupled to the adjustment device. The fine adjustment mechanism is configured to selectively move the handle and the sheath relative to the adjustment device and the outer stability shaft.

摘要： The techniques of this disclosure generally relate to a valve prosthesis including a one-piece molded valve comprising commissures and reinforcement members applied to the commissures. The reinforcement members provide reinforcement and strength to the commissures, e.g., from the stress applied by commissure stitching on the commissures.

摘要： A tissue-removing catheter for removing tissue in a body lumen includes an elongate body having an axis and proximal and distal end portions spaced apart from one another along the axis. A tissue-removing element is mounted on the distal end portion of the elongate body. The tissue-removing element is configured to remove the tissue as the tissue-removing element is rotated by the elongate body within the body lumen. A motor operatively engages the elongate body for driving rotation of the elongate body and tissue-removing element mounted on the elongate body. A controller is operatively connected to the motor and configured to perform a torque response routine to control a speed of the motor based on a set PWM value of the motor and a detected current applied to the motor during rotation of the elongate body and tissue-removing element.
