Title: RE-GENERABLE WEARABLE FILTER FOR LONG-TERM USE
Abstract:
Wearable or insertable device (100, 300) and methods of monitoring a physiological condition of a patient (200) are described herein. Wearable or insertable devices (100, 300) may include a substrate (102, 302) affixable to a patient. The device may also have a re-generable filter with a sampling unit (103) that obtains one or more fluid samples from the patient and a re-generation unit (130) that applies fluid back- flow to the sampling unit (103). In some embodiments, the sampling unit (103) may include a plurality of microneedles (106). The device may also have a detection module (170) and/or an assay module (180) fluidly coupled with the sampling unit (103). The detection module (170) may determine the presence of at least one biomarker (122) contained in the fluid sample(s), and the assay module (180) may determine a measurement of at least one biomarker (122) contained in the fluid sample(s).
