Abstract

A syringe for injecting contrast injection media into a patient. An inlet valve system associated with the syringe, the inlet valve system operable with a contrast injection media having any viscosity within the range of about 1 cP to about 30 cP. An inlet valve system associated with the syringe, the inlet valve system including a valve member having a density of less than or equal to 1 gram per cubic centimeter. A contrast injector system with such a syringe.

Description

[0001] related application [0002] This application claims the benefit of the disclosure of U.S. Provisional Patent Application Serial No. 61 / 416,993, filed November 24, 2010, entitled "Contrast Media Injector Syringe Inlet Valve System," Incorporated herein by reference. technical field [0003] The present application generally relates to an injector system for injecting a medical fluid, such as a contrast medium, into a living organism. Background technique [0004] Many medical procedures, such as angiography, involve injecting a contrast medium directly into the patient. Angiography is a procedure used in the diagnosis and treatment of cardiovascular disease involving abnormal or restricted blood vessels. During angiography, radiographic images of the heart or blood vessel structures are obtained by injecting a contrast agent through a catheter into a patient's veins or arteries. The injected contrast agent can be delivered to a vascular structure in fluid communica...
