1. A manometric catheter probe, comprising:
a flexible printed circuit;
at least one pressure sensor assembly disposed along the flexible printed circuit and coupled therewith, the at least one pressure sensor assembly including:
a body including a central cavity receiving at least a portion of the flexible printed circuit;
an annular recess around the body;
a microelectromechanical systems (MEMS) sensor disposed in the annular recess;
an electrical connector configured to electrically couple the MEMS sensor and the flexible printed circuit; and
a first flexible sleeve disposed over the body in a manner forming a cavity between the first flexible sleeve and the annular recess for containing a fluid, the fluid configured to communicate pressure to the MEMS sensor; and
a second sleeve disposed over the at least one pressure sensor assembly.
