Abstract
A pressure catheter for monitoring changes in pressure within the body is comprised of an outer hollow tube containing a fluid channel and a closed air column having a pressure-compliant member which is deformable upon an increase in pressure. A change in pressure deforms the pressure-compliant member, which modifies the pressure in the air column, and is translated to a pressure sensor which converts the pressure change data to an electrical signal recognizable by a fetal monitor. The pressure catheter of the present invention is particularly suitable for intrauterine pressure monitoring during labor.
