Noninvasive, intrauterine fetal ECG strip electrode
First Claim
1. An intrauterine fetal monitoring electrode assembly comprising:
- a ribbon-like insulating strip having a first and a second side on which to mount electrodes, and having an insertion end and a connector end;
a first electrode disposed on the first side of the insulating strip proximate the connector end;
a second electrode disposed on the second side of the insulating strip proximate the connector end; and
an electrical connector cable being an insulating sheath containing electrical leads, the electrical connector cable having a distal end attached to the connector end of the insulating strip and adapted to provide electrical connectivity between each electrode and a separate electrical lead disposed within the insulating sheath, and a proximal end adapted to be attachable to an input of a fetal monitor.

Abstract
A disposable and noninvasive intrauterine fetal monitoring electrode assembly for monitoring fetal heart rate comprises an electrode strip for insertion into the uterus of a woman in active labor, between and in contact with the tissue of the uterine wall and the baby, and an interconnect cable for connecting the assembly to fetal monitoring equipment. The electrode strip comprises a flexible two-sided insulating strip having one or more electrodes disposed on each side of the strip. An electrical connector cable containing electrical leads provides electrical connectivity between each electrode and a separate electrical lead disposed within the connector cable to the fetal monitoring equipment. The electrode strip of the assembly includes a grip feature by which the electrode strip may be engaged to facilitate its positioning in the uterus.
