A member of a rigid flexible elastic material, the member including a body portion and an aperture portion with the member adapted for delivery through an axial longitudinal channel of a percutaneous delivery subsystem, the aperture portion including an expanded mode having a lateral dimension greater than an inner diameter of the channel when the aperture portion extends outside the channel and a collapsed mode wherein the lateral dimension is not greater than the inner diameter of the channel when the aperture portion is within the channel, the channel including a first axial opening and a second axial opening with the aperture portion transitioning from the expanded mode to the collapsed mode when inserted into the openings and the aperture transitioning from the collapsed mode to the expanded mode when exiting from the openings.

L'invention concerne un élément constitué d'un matériau élastique, flexible, rigide comprenant un corps et une partie à orifices, cet élément étant adpaté pour faire passer par un canal longitudinal axial un sous-système d'administration percutanée, la partie à orifices possédant un mode étendu dans lequel une dimension latérale est supérieure à un diamètre interne du canal lorsque cette partie à orifices s'étend à l'extérieur du canal et un mode replié dans lequel la dimension latérale n'est pas supérieure au diamètre interne du canal lorsque cette partie à orifices se trouve à l'intérieur du canal. Le canal comprend un premier orifice axial et un second orifice axial, la partie à orifices passant du mode étendu au mode replié lorsqu'elle est insérée dans les ouvertures et du mode replié au mode étendu lorsqu'elle sort des ouvertures.
