Abstract
The invention concerns a device for directly delivering an active substance within all or part of a human or animal tissue cell, characterised in that it is in the form of a hollow tube (1), whereof the walls in contact with said tissue are provided with perforations (5) and whereof the distal end (2) is sealed, while the proximal end (3) is shaped so as to receive removable closing means, said tube being capable of bearing a pressure of at least 50 bars.
Claims22
A device for delivering an active substance directly within all or some of a human or animal cell tissue, characterized in that it is in the form of a hollow tube (1), equipped with perforations (5) formed over the entire length of the walls intended to be in contact with the tissue, and of which the distal end (2) is plugged, while the proximal end (3) is shaped in such a way as to accommodate removable closure means, said tube being capable of withstanding a pressure of at least 50 bar.
The device as claimed in one of the preceding claims, characterized in that the outside diameter of the tube is equal to 200 micrometers while the inside diameter of the tube is equal to 100 micrometers.
The device as claimed in one of the preceding claims, characterized in that the perforations (5) are formed in a spiral around the part of the tube that is intended to be in contact with the organ (7) that is to be treated, with a pitch of between 0.5 and 2 centimeters.
The device as claimed in one of the preceding claims, characterized in that the removable closure means are in the form of a plug intended to be screwed onto the proximal end of the tube.
