    Abstract: An intravascular medical device is prepared for shipping by being sealed within a sterile volume of a package. Prior to closing the package, an intravenous liquid solution is pumped into and through the medical device to displace all air bubbles. The liquid is pumped at sterilization temperatures corresponding to when the liquid has a low viscosity, but the liquid is chosen to have a relatively high viscosity at room temperatures corresponding to when the package is opened for use. The liquid solution remains adsorbed to the interior surfaces of the medical device at room temperature against a force of gravity. The strategy reduces the risk of air embolism when a medical device is put into use.

    Abstract: 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.

    Abstract translation: 用于通过降低喷射给定体积的血液所需的血压来改善血管依从性的血管内装置。 该组件包括位于血管系统中的第一可膨胀容器，例如球囊。 第一容器响应于容器中的血流而具有可变体积，并且固定到至少一个可扩张的附接构件。 当附着构件在脉管系统的内部扩张时，优选地，固定构件固定在容器的内部。 组件还包括第二容器，优选地具有固定容积，当流体连接到第一容器时形成封闭的流体系统。 第一和第二容器之间的连接允许在第一容器中的体积变化以将流体流入第二容器。 第二容器可以放置在患者体内的不同位置，优选地位于血管外。
