Abstract
A system and a method for assessing the patency of a vessel or a graft during coronary artery bypass grafting surgery or PTCA, said system comprising a syringe capable of electronically measuring the pressure and flow of a fluid that is injected into the vessel or graft. The system also comprises a reading device connected to said syringe for displaying flow, pressure and flow resistance parameters.
Claims13
A system suitable for assessing vascular patency comprising a syringe with a piston part and a housing, for injecting a fluid into a vessel or a vascular graft, and means for sensing the pressure of the fluid in the syringe and means for determining a flow rate of said fluid, said piston part being arranged to be manually pressable, and said means for determining the flow rate comprising means for electrically or magnetically determining the rate of movement of the piston part of said syringe relative to the housing of said syringe when said piston part is manually pressed.
