A method for placing a device into a target vasculature. The method comprises accessing the target vasculature with an access guide catheter to sub-select a proximal portion of the target vasculature. A rail catheter is tracked into the access guide catheter to place the rail catheter more distally and into a distal portion of the target vasculature. The access guide catheter is removed. A delivery catheter is tracked over the rail catheter. The rail catheter is then removed. A device catheter having the device is placed into the delivery catheter and positioned at a desired location within the distal portion of the target vasculature.

An apparatus including a tether, and an aptation device coupled to the tether at a position corresponding to a location to contact cusps of an atrioventricular valve during systole, wherein the tether and aptation device are suitable for percutaneous delivery to a patient. An apparatus including a support annulus comprising a length corresponding to a circumference of one of an interior portion of an atrium and an atrioventricular valve annulus; and an aptation device coupled to the support annulus corresponding to a location to contact cusps of an atrioventricular valve during at least one of systole when the support annulus is seated in one of an atrium and an atrioventricular valve annulus, wherein the support annulus and aptation device are suitable for percutaneous delivery to a patient. Also, a method of introducing an aptation device to contact cusps or leaflets of an atrioventricular valve.

Systems and methods are adapted for treating the carotid artery. The systems include interventional catheters and blood vessel access devices that are adapted for transcervical insertion into the carotid artery. Embodiments of the systems and methods can be used in combination with embolic protection systems including blood flow reversal mechanisms, arterial filters, and arterial occlusion devices.
摘要:
Interventional procedures on the carotid arteries are performed through a transcervical access while retrograde blood flow is established from the internal carotid artery to a venous or external location. A system for use in accessing and treating a carotid artery includes an arterial access device, a shunt fluidly connected to the arterial access device, and a flow control assembly coupled to the shunt and adapted to regulate blood flow through the shunt between at least a first blood flow state and at least a second blood flow state. The flow control assembly includes one or more components that interact with the blood flow through the shunt.
