The invention relates to a device for applying a filamentous implant by means of a pressure-generating unit which is connected to a housing containing the thread to be implanted. The housing opens out into a channel used for delivering the thread externally. The pressure generation unit generates a static pressure on a fluid contained inside the device, said fluid pushing the thread to be implanted through the distal narrowed tip of the channel, towards the exterior or into a tissue or a body cavity. The fluid remains inside the device in the course of this process. The distal end of the device can be plugged in order to prevent the fluid from exiting after application of the implant. The application can be stopped once an adequate quantity of the implant material has been implanted by severing the thread in the vicinity of the distal end of the channel or at the proximal end.

L'invention concerne un dispositif pour appliquer un implant filiforme à l'aide d'un moyen produisant une pression, qui est relié à un boîtier contenant le fil à implanter. Ce boîtier débouche dans un canal permettant de distribuer le fil à l'extérieur. Le moyen produisant une pression établit une pression statique sur un fluide contenu à l'intérieur du dispositif, lequel fluide pousse le fil à implanter, à travers la pointe rétrécie au niveau distal du canal, vers l'extérieur ou bien dans un tissu ou une cavité corporelle. Lors de cette opération, le fluide demeure dans le dispositif. Afin d'empêcher une sortie du fluide après l'application de l 'implant, l'extrémité distale du dispositif peut être obturée. Pour interrompre l'application après l'implantation d'une quantité suffisante de l'implant, le fil est sectionné au voisinage de l'extrémité distale du canal ou bien au niveau proximal.
