An ultrafast sampler includes a series of Schottky diodes configured with a coplanar waveguide to form a nonlinear transmission line that compresses a local oscillator input to form a series of strobe pulses. The devices can be configured to be disposed within a lumen of a microcatheter that is inserted within neurovasculature above a carotid siphon to a location of a clot. The additional circuit structure is provided in such a way that the minimum structural size, which is determined by a smallest required joint surface of the photoresist on the substrate, is exceeded. A jet drive unit is releasably mounted to a housing extending from the rear of the housing and is operatively coupled to the engine in the housing. The quality of the adhesion is measured by a boiling water peel test.
