Dilatation catheter and constant pressure syringe. |
摘要 |
In a dilatation catheter (10) and constant pressure syringe (12), a pressurized compressible medium is used to maintain pressure on a non-compressible medium. Pressure is applied to a compressible medium in a first chamber (41), in turn applying pressure to a non-compressible medium in a second chamber (39). The use of appropriate quantities of each medium produces a nearly constant pressure as the incompressible medium is ejected from the syringe. |
