Abstract: The endovenous treatment device has a delivery system (1; 2) for delivering of at least one treatment dose, which delivery system (1; 2) includes a wire element (1) for delivery of a treatment dose, which has a distal end part (10) able to be inserted, over at least part of its length, longitudinally into a vein, and which allows at least one treatment dose to be delivered into a vein in the region of the end of said distal end part (10). It additionally includes a drive system (4) by which the wire element (1) for dose delivery can be driven in at least a first given drive direction (R), and a guide (3) which is flexible along all or part of its length. The device includes a holding system (5) by which the distal end part (30) of the guide (3) can be temporarily held with respect to the body of a patient, near the insertion zone (7) of the wire element (1).

Abstract: An endovenous treatment assembly includes a wire element for delivering treatment doses, which is flexible and capable of being inserted, over a portion of its length, longitudinally into a vein, and a positioning and guiding part that manipulates the wire element. The positioning and guiding part includes at least a first means for guiding in translation a first portion of the wire element, the wire element being able to slide in the direction of its length relative to the first guiding means. The positioning and guiding part further includes a first mechanical assembly for removable mounting relative to a drive system, so that the first portion of the wire element can be positioned and guided by the positioning and guiding part so as to be able to be engaged with of the drive system for driving the wire element in the direction of its length at least in a first direction.

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: The invention relates to a method of mapping the intraretinal pH of a retina which is marked by a pH-dependent fluorescent marker, in which the retina is illuminated with a first excitation radiation. According to the invention, a first image of the fluorescence emitted by the retina is formed as a bi-directional matrix of pixels at the wavelength of the peak of the fluorescence emission spectrum. Subsequently, the retina is illuminated with a second excitation radiation and a second image is formed of the fluorescence emitted thereby. Finally, the ratio at each pixel between the levels of fluorescence emitted in response to the two respective wavelengths is calculated, said ratio being representative of the pH of the retina, and a pH map of the retina is deduced.
