MEDICAL DEVICE WITH FLUID ACIVATED ACTUATION MECHANISM

A self-righting ingestible capsule comprising: a) a capsule housing (110, 120) defining a central axis and having proximal and distal ends, b) a sealing compartment (A) within the capsule housing (110, 120) accommodating a solid dose member (130), and comprising a distal exit port (124), c) an actuation compartment (B) fluidically isolated from the scaling compartment (A), d) an actuation member (150) at least partially accommodated in the actuation compartment (B) and arranged for axial displacement thereby moving the dose member (130) distally through the distal exit port (124), e) a helical spring (140) for powering the actuation member (150) in a distal direction, f) a latch component (152) coupled to the actuation member (150) for releasably maintaining the actuation member latched in a proximal position, and g) a dissolvable latch support (160) disposed in the actuation compartment (B), wherein the dissolvable latch support maintains latching of the actuation member (150) in the proximal position by supporting the latch component
