摘要： System and method for contactless vascular flow measurement are provided. Herein, a measurement circuit emits a radio frequency (RF) waveform toward a human peripheral body part and measures micro-vessel motion in an area of interest of the human peripheral body part based on reflections of the RF waveform. Accordingly, the measurement circuit can extrapolate vascular flow information in the human peripheral body part based on the measured micro-vessel motion. In a non-limiting example, the measurement circuit can detect inner organ vibrations to measure pulse rate, strength, and/or pressure caused by radial arterial blood flow changes at the human peripheral body part. By detecting and measuring the vascular flow via the RF waveform, the vascular flow measurement system provides a non-invasive approach to detect and/or prevent peripheral artery diseases. Further, the measurement circuit emits a very low power, non-ionizing RF waveform to help minimize potential health risks to a human body.

摘要： Various cartridge assemblies for surgical instruments are provided. Cartridge assemblies can include active sensors for applying stimuli to a tissue clamped by an end effector of the surgical instrument and a circuit configured to determine a tissue type of the tissue according to a change in the tissue parameter detected by the sensor resulting from a stimulus from the active element. Cartridge assemblies can also include physical features and/or stored data that identify the cartridge. Surgical instruments further can be configured to resolve conflicts when the physical features and/or stored data are not consistent with each other in their identification of the cartridge type.

摘要： Generally, abnormal pressures in the sinus cavity can have physiological effects due to stimulation or injury of various nerves that are in proximity to the sinus, including increased or decreased pressure on the nerves as well as extrusion of the nerves into the sinus cavities due to bony dehiscence. Methods and devices for alleviating disorders associated with the sinus cavities are described. Embodiments herein include diagnosing these disorders by occluding or restricting the sinus ostium and assessing the physiological effects caused by the occlusion/restriction and treating these disorders by navigating/directing a dilating device to the sinus ostium and dilating the sinus ostium. Other embodiments are directed to devices for maintaining the ostial opening.

摘要： A handheld palpation device for remote medical examination comprises a handle to apply pressure to a patient's body using a palpation head. The handle includes an interior space and an opening to the interior space. The palpation head fits inside the opening on one end, and the other end comprises a round pliable head configured to contact the body of the patient when pressure is applied. A pressure pad positioned in the interior space derives electrical pressure data when pressure is applied. A sensor chip in the interior space receives the electrical pressure data from the pressure pad, calculates one or more quantitative pressure measurements, and transmits the quantitative measurements to a communications chip connected to the sensor chip which communicates the quantitative pressure measurements to an external device for analysis using machine learning to provide a clinical assessment using the pressure measurements.

摘要： Methods and devices are described, such as for chest compression depth measurement for CPR performed on infants and for allowing active decompression of a patient's chest during a release phase of a chest compression cycle. An anterior segment of a resilient wrap-around structure may be positioned on the patient's sternum, including a first motion sensor. A posterior segment of the resilient wrap-around structure may be positioned on the patient's back, including a second motion sensor. Chest compressions may be provided such that the first motion sensor moves in fixed relation with the patient's sternum and the second sensor moves in fixed relation with the patient's back. Active decompression may be allowed for, including the resilient wrap-around structure exerting an expansive force on the patient's chest wall during a release phase of a chest compression cycle and hastening expansion of the patient's chest during the release phase.

摘要： It consists of a system for palpation of the rectal face of the prostate that transforms the information collected into objective, reproducible and useful information. The system makes it possible to identify areas of high rigidity reaching the entire peripheral area, transforming a diagnostic maneuver for prostate cancer into an objective one, which until now has been subjective and unreliable. All this in a short space of time, carried out in a less aggressive and more objective way than rectal examination. The device consists of a manual electronic instrument with a handle (1) and a scanning rod (3), which includes at least two concentric force/pressure sensors of different heights, as well as an ultrasonic imaging system which, through means of connection to external devices for analysis/control, allows the data obtained to be analyzed and the anatomy of the prostate being analyzed to be visualized in real time.

摘要： The invention provides a fetal position monitoring system, comprising an abdominal belt or a glove comprising a force and/or deformation sensor arrangement for obtaining resistance information of a plurality of local areas of the abdomen in response to an applied pressure. A data analysis processor interprets the resistance information to derive a fetal position and/or fetal size and optionally also fetal movement and an output is provided giving a representation of the fetal position and/or fetal size and optionally also fetal movement.
This system provides a way of generating an output of the fetal position or size which requires minimum medical knowledge of the user, and it may be used at home.-

摘要： A system and method for measuring biomechanical properties of tissues without external excitation are capable of measuring and quantifying these parameters of tissues in situ and in vivo. The system and method preferably utilize a phase-sensitive optical coherence tomography (OCT) system for measuring the displacement caused by the intrinsic heartbeat. The method allows noninvasive and nondestructive quantification of tissue mechanical properties. Preferably, the method is used to detect tissue stiffness and to evaluate its stiffness due to intrinsic pulsatile motion from the heartbeat. This noninvasive method can evaluate the biomechanical properties of the tissues in vivo for detecting the onset and progression of degenerative or other diseases and evaluating the efficacy of therapies.
