Abstract
The invention relates to a drug delivery device (1, 100), in particular for the delivery of drugs comprising molecules tending to spontaneously form nucleation seeds leading to fibrils, comprising a drug reservoir (2, 102) having a reservoir outlet (107) connected to a device outlet, adapted to deliver a drug fluid to a patient's body, through a pathway (5) including a fluid flow controlling system (4, 104). The pathway further includes a filtration module (6, 106) adapted to retain the nucleation seeds, preferably by forcing them through a filtering membrane pores and on the basis of hydrophobic interaction with the membrane.
