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： A catheter may include an elongate body extending from a proximal end to a distal end and defining a lumen; a push member mechanically coupled to the proximal end of the elongate body; and a slidable push grip disposed about an outer perimeter of the push member. The slidable push grip is controllably engageable with the push member. When the slidable push grip is in an engaged state with the push member, the slidable push grip transmits an axial force to the push member to enable the push member to transmit the axial force to the elongate body. When the slidable push grip is in a disengaged state with the push member, the slidable push grip is movable axially in at least one direction along a length of the push member while transmitting substantially no axial force to the push member.

摘要： A balloon catheter includes a balloon coupled to a shaft. The shaft includes a proximal perfusion portion disposed proximal of the balloon and a distal perfusion portion disposed distal of the balloon. The proximal and distal perfusion portions each are formed by a respective plurality of wire members woven together to form a respective proximal and distal braided shafts. The plurality of wire members are woven together such that a plurality of perfusion openings are formed between the wire members. The plurality of perfusion openings extend from an outer surface of the respective proximal or distal braided shaft to a lumen of the respective proximal or distal braided shaft. A perfusion lumen extends between the proximal perfusion portion and the distal perfusion portion.

摘要： Biodegradable magnesium alloy implantable medical devices are protected to delay onset of corrosion, and thus biodegradability, or to corrode more uniformly. The protection allows for extended effective use of the devices while maintaining biodegradability. Examples of protective coatings include conversion coatings that at least partially remove exposed second phases from a surface of the magnesium alloy and coatings that provide a barrier between water and the surface of the magnesium alloy.

摘要： The techniques of this disclosure generally relate to an assembly including a trifurcated modular stent device. The trifurcated modular stent device includes a main body, a bypass gate extending distally from a distal end of the main body, a primary artery leg extending distally from the distal end of the main body, and a distal artery leg extending distally from the distal end of the main body. The trifurcated modular stent device is delivered via supra aortic access such that the primary artery leg is deployed within the brachiocephalic artery providing immediate perfusion thereof.

摘要： The present disclosure provides a tissue-removing catheter that includes an elongate body, a tissue-removing element, and an inner liner. The elongate body has proximal and distal end portions spaced apart from one another along an axis and is sized and shaped to be received in a body lumen. The tissue-removing element rotates by the elongate body to remove tissue. The inner liner is received within the elongate body, defines a guidewire lumen, and isolates an interior of the guidewire lumen from the elongate body and tissue-removing element, preventing torsional force from transferring from the elongate body and tissue-removing element to the interior of the guidewire lumen. The inner liner includes a distal end margin that may have a construction different from a construction of a second portion of the inner liner proximal of the distal end margin. The distal end margin may be more flexible than the second portion.

摘要： Embodiments hereof relate to methods of delivering a valve prosthesis to an annulus of a native valve of a heart, the native valve having chordae tendineae. A chordae management catheter is positioned within a ventricle of the heart, the chordae management catheter having a displacement component at a distal end thereof. The displacement component has an annular shape and defines a central lumen therethrough. The displacement component is radially expanded to push chordae tendineae within the ventricle radially outward. A valve delivery system is introduced into the ventricle of the heart via a ventricular wall of the heart. The valve delivery system has the valve prosthesis at a distal portion thereof. The valve delivery system is advanced through the central lumen of the radially expanded displacement component towards the annulus of the native valve of the heart. The valve prosthesis is deployed into apposition with the annulus of the native valve.

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： Devices, assemblies, systems, and techniques described herein may deliver a pressure wave to structures of a heart, such an aortic valve. For example, a medical assembly may include an expandable member configured to expand from a collapsed configuration to an expanded configuration, the expandable member configured to at least partially define a channel through the expandable member in the expanded configuration and one or more electrodes carried by the expandable member. The one or more electrodes may be configured to transmit an electrical signal through a fluid to cause the fluid to undergo cavitation that generates a pressure wave within the fluid.
