Definitions
- the present invention relates to devices for aiding in the treatment of living cells in a given medium by application of electrical pulses in combination with the action of medicinal substances, a technique known as electrochemotherapy, which find particularly advantageous applications. in the treatment of cancerous tumors or the like, but also in the laboratory in the treatment of cell cultures, liposomes, etc.
- This applicator includes electrodes and a pulse generator. It comprises at least three needles intended to be introduced into the tissues to be treated and to define a treatment volume, arranged at the vertices of an equilateral triangle and forming pairs of needles, and a switch of needles addressing the pulses produced by the pulse generator successively on the different pairs of needles.
- This device according to the prior art is shown diagrammatically in FIG. 1 of the drawings appended to the following description, in which the references 1 to 3 represent the three needles of a unitary module 4 forming the base of the device. It is understood that the device actually comprises a plurality of these unit modules which combine with each other to form a treatment volume 5 which, due to the shape of the unit modules 4, affects the general shape of a cylindrical volume with substantially cross section -. hexagonal.
- FIG. 1 represents two successive positions 5 and 10 of the applicator and illustrates the fact that, in order to be able to treat certain parts of the tumor, for example the small volume with triangular section 13, it is necessary to reprocess parts that have already been, in this case volume 12. It is therefore apparent that the total duration of treatment is very long and that the treatment is more painful and traumatic for the patient, than it should be ,
- the needles of the applicator 50 are predisposed in a matrix on an auxiliary support, in. relative locations identical to those of the recessed housings 31 on the support 52 and covered by a protective envelope.
- the tips 32 are then plugged into the bases 30, then the envelope protecting the needles is removed.
- the device according to the invention undoubtedly has advantages compared to the devices of the prior art, more particularly compared to that described in the document cited in the preamble.
