Title (EN) IMPLANTABLE INFUSION DEVICE
(FR) DISPOSITIF DE PERFUSION A IMPLANT
Abstract: front page image
(EN)Multiple embodiments of an implantable infusion device for delivering precisely regulated dosages of drugs, each device including reservoir means (16) for containing the drug, catheter means (22) for delivering the drug to the body and an actuating means (44) which is responsive to a signal applied externally of the body for initiating delivery of a precisely regulated dosage. In one embodiment, the device is implanted subcutaneously to permit actuation by a solenoid driven element responsive to coded telemetry signal applied through the skin. In additional embodiments, the reservoir is pressurized for example, by means of vapor pressure or a mechanical spring, the drug under pressure in the reservoir being released in response to an externally applied signal.
(FR)De multiples formes d"execution d"un dispositif de perfusion a implant pour l"injection de doses precisement reglees de medicaments sont decrites, chaque dispositif comprenant un reservoir (16) pour contenir le medicament, un catheter (22) pour l"emission du medicament dans le corps et un moyen d"actionnement (44) qui repond a un signal applique de maniere externe au corps pour engendrer l"emission d"un dosage regle avec precision. Dans une forme d"execution le dispositif est implante de facon sous-cutanee pour permettre l"actionnement au moyen d"un element mis en action par un solenoi, en reponse a un signal telemetrique code applique au travers de la peau. Dans d"autres modes d"execution, le reservoir est pressurise, par exemple, au moyen d"une pression de vapeur ou d"un ressort mecanique, le medicament sous pression dans le reservoir etant relache en reponse a un signal applique de maniere externe.
