ENDOVASCULAR COMPLIANCE ASSEMBLY

摘要

An endovascular assembly for improving vessel compliance by reducing the blood pressure needed to eject a given volume of blood. The assembly comprises a first expandable container, a balloon for example, positioned in the vascular system. The first container has a variable volume in response to blood flow in the vessel, and is fixed to at least one expandable attachment member. When the attachment member is expanded inside of the vasculature, the attachment member is preferably fixed inside the vessel. The assembly further comprises a second container, preferably having a fixed volume that forms a closed fluid system when fluidly connected to the first container. The connection between the first and second container permits a change in volume in the first container to flow fluid into the second container. The second container can be placed in a different location inside of the patient, preferably outside of the vessel.

1. An endovascular assembly for improving vascular compliance comprising:
a first container being expandable and endovascular, when expanded in a vessel, the first container has a volume changing in response to blood flowing thereby; a second container being implantable and fluidly connectable to the first container; and wherein when connected, the first container and the second container form a closed fluid system, whereby a change in volume of the first container due to blood flowing thereby is accompanied by a change in pressure of the closed fluid system.
