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 virtual sphere (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, and being mobile on the support between
• first and second extracted positions, in which the first and second needles are outside said virtual sphere, respectively, and
• first and second inserted positions, in which the first and second needles are maximally inserted in the virtual sphere, respectively,
• via first and second intermediate piercing positions in which, respectively, the first and second needles extend along first and second insertion axis and the first and second tips are located on first and second insertion points belonging respectively to first and second hemispheres of the virtual sphere 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 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 and second needles compress the virtual sphere toward the median radial plane of the rim when they reach the first and second intermediate piercing positions.

• a first inserted position, in which the first needle is maximally inserted in the virtual sphere,
• via a first intermediate piercing position in which the first tip is located on a first insertion point belonging to a first hemisphere of the virtual sphere, the device comprising a counter base defining a counter contact surface extending along a second hemisphere of the virtual sphere, the first and second hemisphere being 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 needle being mobile on the support so that, during an insertion operation starting from the first extracted position and ending at the first inserted position, the first needle and the counter contact surface compress, or pinch, the virtual sphere toward the median radial plane of the rim when the first needle reaches the first intermediate piercing position.
