    摘要： A closure device includes a delivery member, a sealing material applicator, and an expandable member. The delivery member is insertable through a tissue tract to a vessel puncture. The sealing material applicator is configured to supply a volume of sealing material to the delivery member and includes first and second multi-chamber devices and a valve assembly. Each chamber of the first and second multi-chamber devices holds a component of the sealing material, and operating the valve assembly permits mixing of at least some of the components prior to connecting the sealing material applicator to the delivery member. The expandable member is positionable within the vessel to temporarily seal closed the vessel puncture from within the vessel. The closure device is operable to deliver the sealing material from the sealing material applicator, through the delivery member, and to the tissue tract to seal closed the vessel puncture from outside the vessel.

    摘要： Devices and methods for improving the function of a valve (e.g., mitral valve) by positioning a spacing filling device outside and adjacent the heart wall such that the device applies an inward force against the heart wall acting on the valve. A substantially equal and opposite force may be provided by securing the device to the heart wall, and/or a substantially equal and opposite outward force may be applied against anatomical structure outside the heart wall. The inward force is sufficient to change the function of the valve, and may increase coaptation of the leaflets, for example. The space filling device may be implanted by a surgical approach, a transthoracic approach, or a transluminal approach, for example. The space filling portion may be delivered utilizing a delivery catheter navigated via the selected approach, and the space filling portion may be expandable between a smaller delivery configuration and a larger deployed configuration.

    摘要： Devices and related methods for treating heart conditions, including, for example, dilatation, valve incompetencies, including mitral valve leakage, and other heart failure conditions, may operate to assist in the apposition of heart valve leaflets to improve valve function. A method for improving the function of a valve of a heart includes placing an elongate member transverse a heart chamber so that each end of the elongate member extends through a wall of the heart, and placing first and second anchoring members external the chamber. The first and second anchoring members are attached to first and second ends of the elongate member to fix the elongate member in a position across the chamber so as to reposition papillary muscles within the chamber. A method of treating the valve may include real-time monitoring the valve function and adjusting the device based on data obtained during the real-time monitoring.
