ENDOVASCULAR COMPLIANCE ASSEMBLY

摘要

An endovascular assembly (10) for improving vessel compliance by reducing the blood pressure needed to eject a given volume of blood. The assembly comprises a first expandable container (12), a balloon (32) for example, positioned in the vascular system. The first container (12) has a variable volume in response to blood flow in the vessel, and is fixed to at least one expandable attachment member (16). When the attachment member (16) is expanded inside of the vasculature, the attachment member (16) is preferably fixed inside the vessel. The assembly further comprises a second container (20), preferably having a fixed volume that forms a closed fluid system when fluidly connected to the first container (12). The connection between the first container (12) and the second container (20) permits a change in volume in the first container (12) to flow fluid into the second container (20). The second container (20) can be placed in a different location inside of the patient (13), preferably outside of the vessel.
