An intraocular pressure measurement arrangement is disclosed for measuring pressure of an eye of a patient. The arrangement can include at least one source for producing mechanical waves of several frequencies from a distance to the eye of the patient to generate at least one surface wave to the eye, a detector for detecting at least one surface wave from a distance from the eye to extract surface wave information, and a device for determining pressure information of the eye based on the surface wave information.

Method and arrangement for eye pressure measurements

Various embodiments are described herein for a device for using acoustic or mechanical energy to perform an action at a target site of an object. The device comprises a conduit having an aperture disposed at the target site, a displacement signal source for generating a mechanical displacement signal, a coupling assembly having for coupling the displacement signal source to the conduit, a pressure controller coupled to the proximal end of the conduit to vary an amount of pressure in the conduit when obtaining a first entity from or delivering a second entity to the target site, and a control unit for controlling the displacement signal source to generate the mechanical displacement signal based on a desired acoustic or mechanical wave mode.

Method and apparatus for extracting and delivery of entities

The present invention relates to a device exploiting magneto-hydrodynamics (MHD) for localized delivery of material into a target or extraction of material from a target. The device includes a frame () comprising a space () for conductive fluid and the material, at least one pair of electrodes (A,B) facing each other, a source of electric current (), a magnet (), and an opening (). The electric current and the magnetic field are synchronized so that the material can be moved from the volume between the electrodes through the opening towards the target or from the target through the opening towards the volume. According to the invention the volume is &#x2264;2000 mm, in proviso that mean distance between tips of the electrodes is &#x2264;20 mm.

Device and method for localized delivery and extraction of material

The application relates to a device () for non-invasively sampling interstitial fluid comprising one or more analytes from dermis () to skin surface () by using the magneto-hydrodynamic effect. The device comprises a first electrode () and a second electrode () adapted to be positioned adjacent to the skin surface, the first electrode separated from the second electrode by a distance (), a power source () adapted to induce an electric current through the first electrode, the interstitial fluid and the second electrode, and also a magnet () adapted to produce a magnetic field to the interstitial fluid. Direction of the magnetic field and direction of the electric current produced by the magnet and the power source, respectively, is such that Lorentz force drives the fluid from the dermis towards the skin surface.

Device for sampling one or more analytes

An intraocular pressure measurement arrangement is disclosed for measuring pressure of an eye of a patient. The arrangement can detect at least one of acoustic reflectivity, optical reflectivity, optical path difference, positioning of intraocular pressure measurement arrangement with respect to the eye, orientation of intraocular pressure measurement arrangement with respect to the eye, shape of cornea and corneal thickness. At least one source can produce acoustic, nonlinear acoustic, mechanical or a nonlinear mechanical wave from a distance, coupling to the eye to generate at least one surface wave. Upon triggering data acquisition, at least one surface wave from a distance from the eye can be detected to extract surface wave information with pressure information of the eye being based on the surface wave information.

Method and arrangement for eye measurements

A medical imaging system () for acquiring medical image data (), the medical imaging system comprising: a tissue treating system () for treating a target volume (); a computer system () comprising a processor (), wherein the computer system is adapted for controlling the medical imaging system; and a memory () containing machine readable instructions (). Execution of the instructions cause the processor to: acquire () medical image data; reconstruct () a medical image () using the medical image data; receive () an image segmentation seed () derived from a treatment plan (), and identify () a treated volume () in the medical image by segmenting the medical image in accordance with the image segmentation seed.
