An electronic catheter stethoscope measures and analyzes acoustic fields and dynamic pressure variations in the gaseous or liquid fluid inside a conventional medical catheter that is positioned in a patient's urologic, digestive, reproductive, cardiovascular, neurological or pulmonary system. Measurement transducers are installed in a housing connectable to multiple preselected medical catheters. The transducers detect bodily functions that are transmitted to the preselected catheter from within the body. The transducers, housing, electrical interface and signal processing electronics are positioned outside the body.

In certain embodiments, a method for communicating with a fetal environment, including providing, on an electronic device, a user interface configured to facilitate communication of signals between the electronic device and at least one implanted device located in proximity to a fetus, and responsive to a user selecting a communication selection element, causing the communication of signals inclusive of content data to be performed between the electronic device and implanted device.

A monitoring system comprising: a uterine insert comprising an insert extension, wherein the insert extension comprises at least one sensor; a deployment module engageable with the insert, and configured to allow the insert extension to bend when the module is engaged with the insert; a system control device operationally coupled to continuously receive signals from the at least one sensor and to convert the signals into data representing the signals, and a display operationally coupled to display the data from the system control device.

A non-invasive and accurate vagina evaluation device and uterine evaluation devices are provided that measure the receptivity (uterine implantation capacity) of the mother's body to a fertilized egg implanting itself into the uterus. A first vagina evaluation device includes: a main body stretchable and expandable after insertion into a vagina, followed by air injection thereinto; four electrodes brought into contact with the vagina wall as the main body expands and stretches; and fixation means configured to fix the interval of arrangement of the electrodes. Second and third uterine evaluation device include: a flexible and rod-shaped main body for insertion into a uterine cavity; and four or two impedance electrodes arranged with a predetermined interval therebetween in an insertion direction of the main body and brought into contact with an endometrium of the uterine cavity to measure a uterine endometrial impedance generated between the endometrium and each of the electrodes.

A system obtains a maternal electrocardiogram (ECG) signal that represents an ECG of a pregnant mother during a first time interval. The system further obtains a mixed maternal-fetal ECG signal that represents a combined ECG of the mother and her fetus during the first time interval; processes the maternal ECG signal and the mixed maternal-fetal ECG signal to generate a fetal ECG signal that represents the ECG of the fetus during the time interval, the fetal ECG signal substantially excluding the maternal ECG signal; and provides an output based on the fetal ECG signal.

The present invention relates to a method for long term, continuous, monitoring of pregnant mammals particularly to detect the onset of labor. For The example, the method enables communication of data representing impedance through tissue of a cervix of a pregnant mammal an external module for display and monitoring of the collected data by a clinician.

A first aspect of the invention provides a monitoring system, comprising: an implantable sensor device, shaped and dimensioned for implantation in a human body for measuring conditions within the human body to generate sensor data, the sensor device having a single axis antenna; and a wearable receiver device, for wirelessly receiving the sensor data generated by the implantable sensor device, wherein the receiver device comprises Helmholtz coils, wherein the Helmholtz coils are arranged to communicate with the single axis antenna so as to wirelessly charge the sensor device and receive the sensor data.

The invention is generally a system, apparatus, and method for monitoring and measuring a change in intrauterine pressure without rupturing the amniotic sac. A catheter is coupled to a pressure sensing module. The pressure sensing module is configured with a chamber that is in fluid communication with a balloon of the catheter. The chamber includes a pressure-sensing membrane coupled to sensing circuitry. The sensing circuitry is configured to detect a pressure applied to the pressure-sensing membrane and communicate the condition to a monitor of the system. Methods include inserting the catheter through the cervix so that the balloon may be inflated and situated in the lower segment of the uterus, resting against the amniotic sac. Because the balloon of the catheter is in fluid communication with the pressure-sensing membrane, pulsations of the amniotic sac will be sensed by the sensing circuitry of the pressure sensing module.

A system for detecting the onset of labor in a pregnant woman. The system includes a disposable cervical device configured to be self-inserted by the pregnant woman, the cervical device measures attributes of a cervix of the pregnant woman, and a smartphone application configured to receive data from the cervical device and to provide an indication of immediate onset of labor or risk of onset of labor within a predetermined time frame.
