Ophthalmologic Drug Delivery Platform

High precision in the treatment of age-related macular degeneration. For a research project of the TU Munich (Augenklinik und Poliklinik, Klinikum Rechts der Isar, Dr.-Ing. M. Ali Nasseri) we provide a set of piezo driven  SLC-1750 stages with integrated position encoders. With a travel range of 31 mm and an outer dimension of only 17 x 50 mm2 the stages are a perfect compromise between travel range and compactness. These piezo driven linear stages are the main part of a hybrid parallel-serial kinematic used as a pre-generation medical device that enables ophthalmologists to improve administration of substances such as drugs and stem-cells to desired targets located below the retina.
The design of the kinematic system allows an end-effector precision of 14 μm (x), 10 μm (y) and 4 μm (z). A detailed explanation about the applications of such a drug delivery platform can be found in recent publications of the group [1].
