| 摘要 |
The invention relates to a device for regulating the flow of blood in blood vessels, comprising one or more flow stoppage elements, each comprising: a flareable proximal end, flareable between a flared, flow stoppage configuration and a substantially flattened, flow permitting configuration, and a middle section extending from the proximal end to terminate in a distal end, forming flexible, hollow cones. Blood flowing back down the blood vessel between heartbeats is caught in the three temporary blood storage areas so formed, and is forced back out as blood is pumped through the system by the heart. |
