    摘要： A retrograde flow system is configured for treating an artery. The system includes an arterial access device adapted to be introduced into an artery and receive blood flow from the artery. A shunt fluidly is connected to the arterial access device, wherein the shunt provides a pathway for blood to flow from the arterial access device to a return site. A flow control assembly is coupled to the shunt and is adapted to regulate blood flow through the shunt between at least a first blood flow state and at least a second blood flow state. A shut-off valve assembly automatically blocks fluid flow through the shunt in response to injection of the fluid into the arterial access device.

    摘要： A system for removing an in-place intravascular device such as a catheter or guidewire from a patient's body lumen such as from a coronary artery and advancing a catheter or other similar device through the vascular system until its distal end is located at a desired location within the vascular system. The system includes an exchange catheter, which may be a dilatation catheter, having a flexible strand forming a loop at the distal end of the catheter which is adapted to be disposed about the guidewire or catheter which is in-place within the patient. The loop is tightened about the elongated intraluminal in-place device to be removed so that the catheter can be advanced over the in-place device until the distal end of the catheter is at a desired location within the patient's vasculature. The catheter may be used to perform a diagnostic or therapeutic procedure such as an angioplasty or a replacement device may be advanced through an inner lumen and out the distal end of the catheter.
