Patent

CA 2431688

Implantable, refillable, rate controlled drug delivery is disclosed that includes a base structure (120) having at least a first opening and a second opening, the base structure defining a chamber (160), a septum (110) covering the first opening and configured to substantially prevent leakage from the first opening to an exterior of the device, a drug delivery tube (130) comprising a first and second distal end, wherein the first distal end of the tube communicates with the chamber through the second opening, and at least one rate-limiting permeable membrane (150) disposed across a passage between the base structure and the second distal end of delivery tube, which membrane passively regulates drug delivery. The drug delivery device is used to provide controlled drug delivery to an internal portion of the body and is advantageously leak-proof and does not rely on a pressure differential to drive the drug from the device.

L'invention concerne un dispositif de distribution de médicament à vitesse contrôlée, implantable, et pouvant être rechargé comprenant une structure de base dotée d'au moins une première et d'une seconde ouvertures, ladite structure de base définissant une chambre; un septum recouvrant la première ouverture et configuré de façon à empêcher sensiblement une fuite de ladite première ouverture vers l'extérieur du dispositif; un tube de distribution de médicament comprenant une première et une seconde extrémités distales, la première extrémité distale communiquant avec la chambre par l'intermédiaire de la seconde ouverture; et au moins une membrane perméable limitant le débit disposée sur un passage situé entre la structure de base et la seconde extrémité distale du tube de distribution, ladite membrane régulant passivement la distribution de médicament. On utilise ce dispositif pour distribuer un médicament de manière contrôlée à une partie interne du corps, ledit dispositif étant avantageusement étanche et ne dépendant pas d'un différentiel de pression pour entraîner le médicament hors de celui-ci.
