A device for measuring a force exerted on a body comprises a flexible rod having a proximal end and a distal end intended to come into contact with the body and to apply a force tending to deform the body near a point of contact. The measuring device also comprises an image capturing device, which is rigidly attached to the proximal end and oriented toward the distal end of the flexible rod, for providing at least one depth map of the body near the distal end of the flexible rod. The device may be used to perform a method of measuring the force exerted on the body and a method of characterizing the rigidity of a body

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.

A system for measuring capillary refill time includes a wearable device and a control unit. The wearable device includes a force sensor to obtain a force signal and an optical sensor to obtain an optical signal. The system ensures that an applied force is acceptable in both magnitude and duration, and that a duration over which the applied force is released or removed is acceptable. These factors can establish that a capillary refill time determined or calculated therein is accurate. The system can also determine the capillary refill time based on the force and optical signals obtained by the force and optical sensors, respectively.

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.

An example device for measuring a digital capillary refill time (CRT) can include a wearable component, a processor, and an output. The wearable component includes a touch pressure element and an optical sensor capable of transmitting and detecting optical energy. The detector converts the received optical energy into an electrical signal that represents the optical energy incident on the optical detector. The processor is programmed to receive the electrical signal from the detector, determine the CRT based on the optical sensor data, and output the electrical signal or the determined CRT.
