Abstract: The invention relates to a system for laser photocoagulation of the retina, comprising: a photocoagulation laser (1); an optical path (5) connecting the upstream photocoagulation laser (1) to a downstream laser outlet opening (6) intended to be positioned in front of the retina; an adaptive optical element (9) positioned in the optical path and configured to modify the wavefront of the laser beam being propagated in the optical path, in order to compensate for aberrations of the eye that occur as far as the retina; a position control loop (10) controlling a first actuator (14) positioned in the optical path downstream of the adaptive optical element in order to control the position of the laser outlet opening relative to the retina to be treated; and at least one imaging device (8) configured to obtain an image of the retina diverted from the optical path.

Abstract: In various embodiments described herein, retinal diagnostic/treatment systems are provided that have the capability to mark-up a mosaic image in order to do a treatment plan; illustrate with an aiming beam the point where the laser will be fired; fire a laser shot on a predefined or premarked point or spot; and able to stop the laser shot/firing if the current aim of the laser or selected treatment target is not on the treatment plan.

Abstract: To automatically control a treatment during which subcutaneous or intracutaneous irradiation by means of electromagnetic treatment radiation and possibly targeted electromagnetic radiation is carried out, the following steps are implemented: acquisition of several successive images l(t) of the treated zone by means of an external sensor (1), which is sensitive to the wavelength or the range of wavelengths of the electromagnetic treatment radiation or of the targeted electromagnetic radiation, the time interval (?) between two successive images [l(t?1); l(t)] being known, detection and localisation in each image l(t) of a light spot p(t) corresponding to the irradiation spot (S) of the electromagnetic treatment radiation or the targeted electromagnetic radiation, calculation for each light spot p(t) of at least one of the following parameters: the energy [eij(t) or Eij(t)] supplied from the power P(t) of the electromagnetic treatment radiation and the time interval (?) between two successive images [l(t?1); l(

Abstract: Device for treatment of a part of a human or animal body, including: treatment dose delivery means enabling treatment doses to be delivered to the human or animal body, mapping means enabling a zone or a volume of the body to be treated to be mapped and spatially defined in a predefined frame of reference and in a form of mapping data, localisation means enabling the instantaneous position of the treatment dose delivery means outlet to be localised in the form of localisation data in the frame of reference, electronic control means, which, are suitable for recording the mapping data of at least one zone or one volume of the body to be treated, acquired with the help of the mapping means, and which, enable a treatment to be controlled by using, during the course of the treatment, at least the mapping data and the localisation data.

Abstract: In order to connect two plastic tubes end to end, the extremities of which are closed by compression and welding or gluing of the tube wall, the two closed extremities of the tubes are axially aligned and placed in abutment, the two closed and abutting extremities of the tubes are heated from a distance and without contact and the two extremities of the tubes are axially brought together, so as to splay and weld together the extremities of the tubes end to end, while constantly maintaining said extremities in abutment.
