A powered surgical stapling assembly comprising a motor, an end effector, a sensor, a display, and a control circuit is disclosed. The end effector comprises a first jaw and a second jaw movable relative to the first jaw. The end effector is configured to clamp tissue between the first jaw and the second jaw. The sensor is configured to measure a parameter of the tissue clamped within the end effector. The control circuit is configured to monitor the parameter sensed by the sensor and identify when the monitored parameter stabilizes within a stabilization range. The monitored parameter is considered stable when a rate at which the monitored parameter changes falls below a predetermine threshold rate of change. The control circuit is further configured to display to a user when the parameter stabilizes.

A surgical system for use with a surgical instrument in a surgical procedure performed on an anatomical organ is disclosed. The surgical system comprises at least one imaging device and a control circuit configured to identify anatomical structures relevant to the surgical procedure from visualization data from the at least one imaging device, propose a surgical resection path for removing a portion of the anatomical organ by the surgical instrument, and present parameters of the surgical instrument in accordance with the surgical resection path. The surgical resection path is determined based on the anatomical structures.

The guiding and assessment system for cervical examination of gravid patients relates to devices, systems, and methods for use as educational and non-medical intervention facilitation tools for both medical professionals and gravid patients/persons having a baby to achieve a vaginal delivery through non-medical interventions such as position change, gravity positions, massage, pelvic mobility, etc. by assessing the presentation of the fetal head to the maternal pelvis, dilation, and effacement. To accomplish this, the system includes a portable device for measurement of cervical dilation, presentation of fetal position relative to the maternal pelvis, and/or measurement of effacement of the cervix in a gravid patient. The device includes semicircular open rings made of pliable material, as well as a plurality of dilation markings, a plurality of effacement markings, and a plurality of presentation markings, that represent measurements of cervical dilation, effacement and fetal head presentation.

A diagnostic tool and methods of using the tool are provided to quantify an amount of nasal collapse in a patient. The diagnostic tool includes a mask with an endoscope port and an opening to allow air flow, an endoscope with a camera adapted to take an image of the nasal valve, and an air flow sensor adapted to measure an inhalation rate of the patient. The diagnostic tool can quantify a size difference between the nasal valve during inhalation and zero flow by calculating a percentage difference in an area or one or more dimensions of the nasal valve during inhalation and zero flow.

Systems and methods are provided herein that generally involve measuring a prostate or other object. In some embodiments, a finger clip having a roller ring or wheel rotatably mounted thereto is disposed within an inflatable membrane. The roller ring can include a measurement pattern positioned opposite to optical fibers configured to receive light reflected from the measurement pattern. A user can put on the finger clip, position the membrane in proximity to a rectal wall overlying a prostate, and inflate the membrane. As the user slides their finger across the inside of the membrane, which is pressed against the rectal wall, the roller ring can rotate with respect to the fibers such that the fibers move relative to the measurement pattern. A controller can sense light reflected through the fibers from the reference pattern and calculate or estimate various attributes of the prostate based on the reflected light.

The disclosure herein relates to systems, methods, and devices for medical image analysis, diagnosis, risk stratification, decision making and/or disease tracking. In some embodiments, the systems, devices, and methods described herein are configured to analyze non-invasive medical images of a subject to automatically and/or dynamically identify one or more features, such as plaque and vessels, and/or derive one or more quantified plaque parameters, such as radiodensity, radiodensity composition, volume, radiodensity heterogeneity, geometry, location, and/or the like. In some embodiments, the systems, devices, and methods described herein are further configured to generate one or more assessments of plaque-based diseases from raw medical images using one or more of the identified features and/or quantified parameters.

A method for determining blood vessel parameters is provided. The method may include obtaining a blood vessel image of a target blood vessel. The method may also include generating a blood vessel model of the target blood vessel based on the blood vessel image. The blood vessel model is a grid model. The method may further include determining at least one blood vessel parameter of the target blood vessel based at least on the blood vessel model.

A system and method for compensation of angular distortions in a system utilizing light emitters and light sensors disposed on non-parallel jaws may include determining a first point at a first side of a region of interest and a second point at a second side of the region of interest, determining a linear curve including the first and second points, and utilizing the linear curve to remove the angular distortion from the region of interest between the first and second points. A system and method for compensation of angular distortions may alternatively include modeling a non-pulsatile illumination pattern according to the intensities of individual emitters, comparing the pattern according to the model against a non-pulsatile illumination pattern detected using the light sensors, and varying the intensities of the individual emitters based on the comparison until angular distortion has been removed.

A method of performing a cardiac electrophysiology procedure includes using a magnetically-localizable catheter to generate a cardiac model and then removing the catheter from the patient's heart. An electrophysiology catheter, such as a multi-electrode, non-contact mapping catheter, is then inserted into the heart. The electrophysiology catheter is also magnetically-localizable, and therefore can be localized within the model. The electrophysiology catheter is used to perform the electrophysiology procedure, such as electrophysiological mapping or ablation. Advantageously, because the electrophysiology catheter is magnetically-localizable, it can move during the electrophysiology procedure, either deliberately or inadvertently, without invalidating any previously-collected data or requiring recreation of the cardiac model.
