Needle insertion device for the electroporation of a product into an eye

A device comprising:

• a support comprising a support base defining
• a spherical base contact surface extending along a spherical surface(S) having a radius (R) between 10 and 15 mm to match an outside surface of an eye, and
• a circular rim extending in a rim plane, having an axis X and a radius of greater than 5 mm and of less than 8 mm, so as to match the limbus of the eye;
• a first needle and a second needle having a first tip and a second tip, respectively, the first tip and the second tip being oriented in opposing directions, and being mobile on the support between
• first and second extracted positions, in which the first and second needles are outside said spherical surface, respectively, and
• first and second inserted positions, in which the first and second needles are
• maximally inserted in the spherical surface, respectively,
• via first and second intermediate piercing positions in which, respectively, the first and second needles extend along first and second insertion axes and the first and second tips are located on first and second insertion points belonging respectively to first and second hemispheres of the spherical surface which are separated by a plane including the axis X and including a central point at mid-length of the rim, or median radial plane of the rim,
• the first and second needles being mobile on the support in opposing directions so that, during an insertion operation starting from the first and second extracted positions and ending at the first and second inserted positions, the first needle applies a first compression force and the second needle applies a second compression force which is a counter action to the first compression force, such that the first and second needles compress the spherical surface toward the median radial plane of the rim when they reach the first and second intermediate piercing positions,
• further comprising a synchronisation mechanism to synchronize the movements of the first and second needles during said insertion operation.
