摘要：
A catheter assembly (20) incorporating a pre-biased indicator (22), the assembly includes a catheter (26) having a proximal end (28), a distal end (30), and catheter walls (32) defining a catheter lumen (34). The assembly further includes a base (36) located at the proximal end (28) of the catheter, the base defining an opening to the catheter lumen, the base having a first end (42) and a second end (44). An inflatable balloon (24) having a predetermined fill volume is located at a distal end (30) of the catheter. An inflation valve (46) is located on the base (36)； the inflation valve is in fluid communication with the balloon through an inflation lumen (48) defined by the catheter walls (32). The pre-biased indicator located on the base in fluid communication with the balloon is configured to provide a discrete visual signal that the pressure of a fluid in the balloon is different from a predetermined level of pressure or the volume of the balloon is different from the predetermined fill volume.
