Syringe for balloon catheterization |
摘要 |
A unique syringe useful in the inflation and rapid deflation of a balloon used in balloon catheterization (transluminal angioplasty) procedures is disclosed. The syringe has a uniquely actuated thread engaging block which is engaged and disengaged by a rotary cam member interacting with the thread-engaging block. The thread engaging block engages a threaded piston rod which is attached to the piston within the barrel of a balloon catheter syringe. A rotary cam member engages the block so as to exert a positive force on the block, either moving the block into a thread engaging position or moving into a thread disengaging position. The unique syringe may also contain a plunger end face which is structured so that a portion of the piston face is separately actuatable in order to introduce a minor increase or decrease in pressure while the main piston member remains in a stationary position.
