Abstract: A percutaneous circulatory support device includes a housing, a cannula coupled to the housing, the cannula having a first portion and a second portion, and wherein the cannula includes at least one slot disposed along at least the first portion of the cannula, the at least one slot configured such that the first portion of the cannula is defined by a first stiffness and a second portion of the cannula is defined by a second stiffness, the first stiffness being different than the second stiffness.

Abstract: The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to medical devices, systems and methods to treat a regurgitating cardiac valve, including, for example a tricuspid or mitral valve.

Abstract: An attachment mechanism for a medical implant system may include a first part fixedly attached to a distal end of an elongate shaft, the first part having a first longitudinal lumen configured to slidably receive a release wire disposed within the elongate shaft, and a second part fixedly attached to a proximal end of a medical implant, the second part having a second longitudinal lumen configured to slidably receive the release wire. A tubular distal portion of the second part may include an engagement feature configured to non-releasably engage the second part with the medical implant.

Abstract: A method of making a vascular occlusion device may include cutting a tubular member to form an expandable frame including a first hub integrally formed with the expandable frame adjacent a first end of the expandable frame, and a plurality of longitudinally-oriented struts extending in a direction opposite the first end; heat-setting the expandable frame to define an expanded configuration of the expandable frame; sliding a constrainment member over the plurality of longitudinally-oriented struts, the constrainment member being formed using additive manufacturing technology; fixedly securing the constrainment member to the plurality of longitudinally-oriented struts to define a second hub of the expandable frame; and cutting the plurality of longitudinally-oriented struts adjacent the constrainment member and opposite the first end relative to the constrainment member.

Abstract: A buoy system for treating cardiac valve regurgitation comprising a movable plug having atrial and ventricular ends, wherein a through-hole passes from the atrial to the ventricular end, wherein during systole, the plug travels toward a cardiac atrium, wherein during diastole, the plug travels into a cardiac ventricle; a tether having atrial and ventricular ends, wherein the tether passes through the through-hole of the moving plug, wherein the atrial end of the tether projects into an atrium, wherein the atrial end of the tether includes a cap to engage a delivery tool; at least one distal anchor located in the ventricle, wherein the distal anchor is coupled to the ventricular end of the tether, and wherein the system is percutaneously delivered and optionally recaptured via catheter and recapture tool at the cap of the tether, respectively.
