Abstract
Systems and methods are described that may provide an efficient way to retrieve microneedles from tissue. For example, magnetic material may be incorporated into one or more microneedles. The microneedles may be delivered to a region of tissue via a backing material, such as a transdermal patch. The microneedles may provide therapeutic drug delivery and/or diagnostic information about the tissue or, more generally, the body containing the tissue. To retrieve the microneedles, a retrieval magnet may apply a magnetic field to the region of tissue where the microneedles were delivered. The magnetic field may attract the microneedles to aid in extraction of the microneedles from the tissue. In some embodiments, an excitation light source and light sensor may be included in the system and method to determine whether the microneedles were retrieved from the tissue.
