Abstract: A medical device for the delivery of a therapeutic agent by bioprinting including a rod body including a bioprinting cartridge arranged near the distal end of the rod body including a top layer including a solution containing a therapeutic agent; and an absorbent compound capable of converting light energy from laser radiation into thermal energy and arranged to cause heating of the solution including a therapeutic agent to cause a jet of the solution; an optical fiber extending longitudinally within a lumen of the rod body to deliver laser flow onto the absorbing compound.

Abstract: The present disclosure concerns a device for examining a capillary area of the skin of a finger, said device comprising: an optical microscope); —a light source for illuminating the capillary area; —a support comprising a recess for receiving the finger, said recess comprising an opening positioned opposite the microscope; —the microscope being mounted to rotate on the support about a main axis of the finger so as to scan the capillary area from one edge of the finger to the other; —immobilisation means being configured to adjust the dimension of the recess relative to the shape of the finger in order to immobilise the finger in the recess without exerting pressure on the finger. The examination device of the present disclosure is particularly suitable for examining a capillary area of the skin of a finger in order to detect vascular anomalies.
