摘要： The present invention provides a canopy operator for a supported canopy structure of the type having a support structure and an openable canopy attached to the support structure. The canopy operator comprises a conduit and a plurality of support ribs extending from the conduit to support the canopy. The support ribs comprise stiffenable tubes in communication with the conduit, the conduit and stiffenable tubes comprising a conduit system. A supply of non-gaseous material is in the conduit system, and the canopy operator also includes a pump for changing the pressure in the conduit system. The pump may be used to open the canopy by creating a vacuum in one embodiment or by pumping hydraulic fluid into the system in another embodiment. Support rods may extend alongside the stiffenable tubes. The support structure may be a central pole, as in a typical umbrella, or may be a structure such as a solid wall, edge or frame.

摘要： An implanted cardiovascular assist pump is connected with the proximal descending thoracic aorta. The pump inlet is connected with the aorta at substantially the site of the first pressure/flow node from the heart. The pump outlet is connected at substantially the site of the last pressure/flow antinode before the heart. Control of pump speed varies blood flow through the pump. As a fail-safe mechanism, a pump shunt flow path is provided, through one of a variety of disclosed structures.
