Embodiment Construction

[0085] The device according to the invention is particularly suitable for electroporation. In this application, it preferably comprises a generator 2 configured for electroporation of a pharmaceutical composition, a support 4 and along the sliding direction Δ 6 Movable first comb 6a and second comb 6b.

[0086] The first comb member 6a and the second comb member respectively comprise first electrode needles 8a and second electrode needles 8b. All electrode needles are electrically connected to the first terminal 9a of the generator 2 . Together they define an intrusion electrode.

[0087] The support 4 comprises a support base 10 and a plate electrode 12 fixed on the support base and electrically connected to a second terminal 9b of the generator, the polarity of which is opposite to that of the first terminal.

[0088] Thus, the generator is adapted to polarize the plate electrode and the invasion electrode differently in order to generate an electric field enabling electr...

Abstract

The present invention relates to a device comprising: a support (4) comprising a support base (10) defining a spherical base contact surface (18), extending along a virtual sphere (S) and a circular rim (20) extending in a rim plane (P20); and a first and a second needle (8a; 8b) mobile on the support between extracted and inserted positions in which the first and second needles are outside and maximally inserted in said 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 ([delta]8a; [delta]8b) and their tips are located on first and second insertion points (M8a; M8b) belonging respectively to first and second hemispheres of the virtual sphere separated by a 'median radial plane of the rim', an angle (theta) between the median radial plane and any insertion axis being between 70 degrees and 110 degrees.

Description

technical field [0001] The present invention relates to an insertion device for inserting a needle into the eye, and more particularly to an insertion electrode needle of an electroporation device for injecting a product into the ciliary muscle of the eye. Background technique [0002] WO 2016 / 166172 discloses an electroporation device for injecting a product into the ciliary muscle of the eye. The device enables precise and stable positioning of electrode needles into the eye. [0003] However, each needle is inserted approximately tangential to the surface of the eye. Therefore, when the needle hits this surface, the impact of the needle may cause the eye to rotate, thereby hindering the insertion of the needle. [0004] Jigs are known to keep an eye out. However, they are bulky and require additional operators. [0005] There is a need for a solution that facilitates the insertion of needles without the above-mentioned disadvantages. [0006] It is an object of the p...
