A method for a minimally invasive surgical system is disclosed including capturing camera images of a surgical site; generating a graphical user interface (GUI) including a first colored border portion in a first side and a second colored border in a second side opposite the first side; and overlaying the GUI onto the captured camera images of the surgical site for display on a display device of a surgeon console. The GUI provides information to a user regarding the first electrosurgical tool and the second tool in the surgical site that is concurrently displayed by the captured camera images. The first colored border portion in the GUI indicates that the first electrosurgical tool is controlled by a first master grip of the surgeon console and the second colored border portion indicates the tool type of the second tool controlled by a second master grip of the surgeon console.

A balloon catheter (2) of apparatus (1) for monitoring ripening of a cervix (3) in a female subject prior to the onset of labour in a pregnancy comprises a cervix engaging balloon 10 located distally on a catheter (7). The balloon (10) is located in the cervix (3) and inflated with air by a syringe (85) to a pressure of approximately 80 mmHg. As the cervix (3) commences to ripen an opening (11) extending through the cervix (3) increases in volume thus resulting in a fall in pressure in the cervix engaging balloon (10). A microprocessor (86) in a housing 82 on the catheter (7) monitors the pressure in the balloon at predetermined time intervals and determines the volume of the opening (11) extending through the cervix (3) from a look-up table. A communications module (87) in the housing 24 transmits a signal at the end of each predefined time period indicative of the state of the cervix (3) for reception by a smart mobile phone which is configured by an app to display a representation of the current state of the cervix (3).

An apparatus capable of determining the force applied to the tip of an electrical impedance spectroscopy probe comprises: an elongate probe comprising a probe tip attached to a handle, the probe tip having a substantially planar distal end for contacting human or animal tissue; a load cell located in said handle and capable of measuring a force F.sub.loadcell applied axially along a longitudinal axis when said probe tip is in contact with said human or animal tissue; an accelerometer located in the handle for measuring a gravity vector A.sub.axial; processing means for compensating for the mass of the probe tip using said measured force and gravity vector to produce a calibrated measurement of force F applied to said probe tip.

The disclosure provides apparatus and methods of promoting and assessing cervical dilation during induction of labor including apparatus that utilizes impedance planimetry for assessment of cervical dilation during cervical ripening with balloon, prior to induction of labor.

Methods, apparatuses, and systems for measuring collagen organization in the cervix, assessing the health of a woman's cervix (including a pregnant woman's cervix), characterizing the composition and structure of cervical tissue, and measuring preterm labor risk are provided. Polarization sensitive techniques and properties of cervical tissue, including birefringence, can be used. A method can include acquiring in vivo images of cervical tissue, applying Mueller matrix (MM) polarimetry (including 44 Mueller matrix polarimetry), and determining one or more parameters of the cervical tissue using the Mueller matrix (MM) polarimetry. The in vivo images can be analyzed and various parameters that characterize the cervical tissue can be determined. Graphs and maps of the cervical tissue can be generated for use as care provider tools.

A system, method and apparatus for monitoring uterine and/or cervical activity indicative of labor in a patient. The system includes a medical device and a data processor in communication with the medical device. The medical device includes a structural component, a first electrode attached to the structural component, and a second electrode attached to the structural component. The structural component is structured to be in contact with a cervical surface and a vaginal surface of the patient, such that said first electrode is in electrical contact with said cervical surface and said second electrode is in electrical contact with said vaginal surface. The first electrode is adapted to receive an electrical activity of the cervical surface and the second electrode is adapted to receive an electrical activity of the uterus through the vaginal surface. The data processor is adapted to process the electrical activity of the electrodes to detect contractions on a surface of the patient indicative of labor.

The present disclosure provides methods for decreasing the duration of second stage labor by managing the labor process. In one aspect, a tactile feedback device is positioned adjacent the perianal tissues. A mother's labor is monitored for the progression of the baby along the birth canal and adjustments are performed in response to the progression of labor to promote a vaginal childbirth. A perianal support device includes a perianal support member having a pressure surface configured for engagement with tissue adjacent an anal orifice and a pressure detecting system associated with the perianal support member to detect pressure indicative of pressure on the perianal tissue of a patient.

A cervical dilation reading apparatus and method of use to accurately and precisely determine cervical dilation measurements during labor and delivery. The apparatus includes a measuring device having a length with a first portion, a second portion, and a third portion, a first attachment band configured to couple with a first finger, the first attachment band having a fixed attachment fixedly engaged with the first portion of the measuring device, and a second attachment band configured to couple with a second finger, the second attachment band having a slidable attachment slidably engaged with the second portion of the measuring device. The method includes providing a cervical dilation reading apparatus, coupling the first attachment band to a first finger and the second attachment band to a second finger, inserting the first and second fingers into the vaginal introitus and locating the cervix and cervical os, placing the first finger on a first side of the cervical os and extending the second finger away from the first finger to a second side, opposite the first side, of the cervical os, thereby extending the length of the measuring device between the first and second fingers to an extended state, ensuring that the measuring device length is equivalent to the distance between the first and second fingers by pulling on the third portion of the measuring device if neccesary, removing the first and second fingers, and determining a diameter of the cervical os by the length of the measuring device in the extended state between the fixed attachment and slidable attachment.

A vaginal dilation device is provided that may include any of a number of features. One feature of the vaginal dilation device is that it is configured to dilate vaginal tissue during labor to prevent tissue damage. Another feature of the vaginal dilation device is that it can be manually controlled to dilate vaginal tissue, or can be automatically controlled to dilate vaginal tissue. In some embodiments, the vaginal dilation device is configured to measure a force applied by the device to tissue. In other embodiments, the vaginal dilation device is configured to apply a constant force to tissue. In other embodiments, the vaginal dilation device is configured to expand at a constant rate. Methods associated with use of the vaginal dilation device are also provided.
