| 摘要 |
The present invention provides a graft haemodynamic control device suitable for reducing anastomotic intimal hyperplasia, comprising a cylindrical body, optionally with control vanes therein, which connects an artery to a bypass graft and which controls the flow of blood therebetween. The device is made of any compliant material, usually a plastic material such as PTFE, Dacron or Goretex and coated with Teflon. The device is less compliant than the graft. It may be attached to the artery and the graft by recognised techniques. |
