Abstract: In one example aspect, a system is disclosed that includes an image capture device; a capillaroscope attachable to the image capture device, the capillaroscope including: a light source configured to provide offset light at an angle and location offset from a center horizontal axis and produce oblique remitted light off a patient site; a reverse lens through which the oblique remitted light passes therethrough; and one or more telescopic lenses through which the remitted light passes therethrough to a lens of the image capture device after passing through the reverse lens.

Abstract: A cartilage dicing device according to an embodiment of the present invention includes blades disposed in a housing configured to mitigate entry of the cartilage into the housing of the device. The device includes a number of circular blades used to dice the cartilage in a uniform fashion. The blades are disposed in a housing with a base that prevents the tissue from entering the body of the housing, which ensures that more of the tissue is available to be diced and used in a medical procedure. The blades are spaced at uniform distance.

Abstract: Techniques for label-free determination of a value of at least one blood property are presented. The techniques may utilize a device that includes an optical objective including at least one lens, at least a first light source situated so as to provide light to a body part at a location that is off-center from a central axis of the objective, at least a first electronic detector situated to receive light gathered by the optical objective and generate image data, at least one electronic processor communicatively coupled to the first electronic detector, the at least one electronic processor configured to determine the value of the at least one blood property based at least in part on the image data, and an output interface communicatively coupled to the at least one electronic processor and configured to provide the value of the at least one blood property.

Abstract: An apparatus, and corresponding method, for determining a property of an eye includes a housing with a proximal port that receives an eye and also light from the eye. The housing further includes a distal port, and the two ports together form a visual channel providing an open view to enable the eye to see target indicia external to and spaced away from the housing. A wavefront sensor within the housing is configured to receive the light from the eye via the optical path and to measure a wavefront of the light. A determination module determines an objective refractive correction based on the wavefront and predicts a subjective refractive preference of a person having the eye based on the objective refractive correction. Embodiments can be handheld, and binocular, and predict subjective refraction based on demographic and other information.

Abstract: An apparatus, and corresponding method, for determining a refractive property of an eye includes a housing with a port configured to receive an eye and also light from the eye. A tunable lens can be mounted to the housing to apply a variable focal power to the light from the eye and to pass the light along an optical path toward a wavefront sensor within the housing. The wavefront sensor can receive the light via the optical path and measure a wavefront thereof. A determination module can be configured to determine a property of the eye based on the wavefront. Embodiments can be handheld, portable, and open view, while providing objective wavefront aberrometry, subjective phoroptry, and accommodation and presbyoptic evaluation, as well as lensometry functions.

Abstract: An embodiment in accordance with the present invention provides a handheld cryoprobe for use in percutaneous cryotherapy of tumorous masses. It includes a probe attached to a CO2 gas dispensing backend. The probe has specifically optimized parameters designed for use with CO2 gas and is made out of a partially hollowed and threaded aluminum rod providing maximum heat exchange. The system backend regulates flow of compressed CO2 gas while throttling and cooling the gas coolant to the cytotoxically low temperatures necessary for targeted tumor cell death. Additionally, the incoming initial stream of CO2 gas is throttled by the Joule-Thomson nozzle on the backend. The low temperature exhaust gas is then used to pre-cool all subsequent incoming gas, resulting in an even lower temperature at the probe tip, which provides a positive feedback loop, continually decreasing the gas's temperature. The temperature drop is caused by the Joule-Thomson effect.

Abstract: Eye prescriptions may be determined by providing a simple, easy to use, portable device with a specially configured targeting light source that aligns the eye, mitigates accommodation, and provides accurate results. Unlike stationary, closed view autorefractors, this device typically is portable, self-usable, relatively inexpensive, enabling more widespread use across the world.
