Title: PRESSURE CATHETER DEVICE
Abstract:
A pressure-sensing catheter (10) comprises an elongate member (15) and a monitor lumen (30). The pressure-sensing catheter may have a hollow pressure-compliant member (40) in fluid communication with the monitor lumen and thereby define a fluid column. A connector apparatus can be in fluid communication with the monitor lumen, and can comprise a first complementary connector (72) and a second complementary connector (98). One of the first complementary connector and the second complementary connector can have a pressurizing device that can displace a volume of fluid located within a bore of the other complementary connector into the fluid column, wherein the ratio of the volume of displaced fluid to the volume of the fluid column ranges from about 1:2 to about 1:4. The pressure catheter can comprise a radio-opaque band circumscribing the exterior of the elongate member.
