A microfluidic pressure sensor may include a bioinert shell having a cavity disposed therein. The cavity may include a reservoir and hydrophobic channel fluidly connected to the reservoir. Changes in pressure outside of the microfluidic pressure sensor may cause at least a portion of the shell to inflect into the reservoir thereby the fluid to move into the channel. The microfluidic pressure sensor may be bodily injected and the fluid level in the cavity may be detected using an ultrasound. The fluid level may be translated into a pressure measurement. The microfluid pressure sensor and uses thereof are suitable for bodily pressure measurements, including intra-abdominal pressure.

A method performed by a computer correlates vesicoelastic pressure data (10, 12, 14) with volume data and calculates vesicoelastic work performed by the bladder (20), wherein the amount of vesicoelastic work performed by the bladder (20) is determined by calculating an area under said vesicoelastic pressure data (10, 12, 14) when said vesicoelastic pressure data (10, 12, 14) is correlated against the volume data.

Methods and systems monitor and assess brain bioimpedance through the use of an ocular window that assesses dynamic changes in cerebral blood volume (CBV). That ocular window is implemented through an ocular bioimpedance device that, in a non-invasive manner, measures numerous different brain health indicators using the bioimpedance measurements collected through the regions around the eyes. The ocular bioimpedance device may be goggles with localized measurement electrodes that include cathodes and anodes.

A device for detecting the characteristics of the prostate includes: an insertion element that is intended to be inserted through the anus into a subject’s rectum, a pressure sensor which is mounted on an expandable element and which is configured to detect the elasticity of the prostate tissues of the subject and/or at least a morphological and/or dimensional characteristic of the prostate of said subject, the expandable element which is configured to assume a first condition, in which it is housed in the insertion element, and a second a condition in which the pressure sensor is brought into contact with the prostate, an extractor, associated with the insertion element, which remains external to the anus of the subject, and an introducer element configured to be inserted inside the anus of the subject for stabilization of the device with respect to the anus of the subject.

An endoscopic system includes a processor. The processor generates from a measured value of pressure in a lumen of a subject a first temporal change image of the pressure in the lumen, generates an observation image for observing an opened/closed state of a valve portion in the lumen of the subject in real time from an image pickup signal obtained by picking up an image of the opened/closed state of the valve portion in the lumen in real time using an endoscope, and generates a superposition image by superposing the first temporal change image and the observation image in a temporally synchronized manner.

A computed tomography (CT) image processing apparatus and a CT image processing method are provided. The CT image processing apparatus may generate a virtual monochromatic image (VMI) by applying a weight to each of first, second, and third images corresponding to three different energy ranges. The CT image processing apparatus may set a region of interest (ROI) on a CT image, determine a VMI at an energy level at which a CNR of the ROI is at a maximum among a plurality of VMIs, and display the determined VMI.

A method includes receiving, from a primary pressure sensor, a pressure measurement indicative of a pressure of a patient cavity and controlling, by an insufflator, a supply of the insufflation fluid to the patient cavity based on the pressure measurement from the primary pressure sensor. The method further includes delivering, by a trocar, the supplied insufflation fluid to the patient cavity via an access port, wherein: the access port comprises a seal and a retractor; and the access port facilitates access therethrough to the patient cavity.

A portable device is configured to connect directly to an intraosseous (IO) catheter and provide a clinician with actionable information to determine whether the catheter is placed correctly, such as whether the catheter is placed in the medullary cavity of bone. The device provides this information leveraging the presence or absence of arterial pressure waveforms. A method for assessing placement of an intraosseous catheter includes coupling a pressure transducer to an IO catheter placed in tissue, obtaining a continuous pressure waveform from a pressure signal provided by the pressure transducer, and assessing placement of the catheter based on the continuous pressure waveform.
