The Mercator MedSystems® Bullfrog® Micro-Infusion Device is a wire-guided, endovascular catheter that consists of a perpendicular microneedle, which is sheathed by and contained within a semi-rigid polymer actuator. The device is designed to be advanced to target vasculature and hydraulically actuated to move the microneedle tip through the external elastic lamina to deliver substances to adventitial and perivascular tissues. A compliant stabilizing balloon inflates with the actuator to provide a force opposite the needle tip for proper seating of the needle. The needle is retracted within the sheathing structure by vacuuming the hydraulic actuator.
A flexible tube designed primarily to enable the delivery of diagnostic or therapeutic solutions into the peripheral vasculature during a cardiovascular procedure (e.g., delivery of an antithrombotic agent); some types may in addition be applied to coronary or pulmonary vasculature. It is percutaneously introduced and may include features such as side holes for infusion across a specific region, an expanding frame to disrupt clotted blood to improve diffusion, or a balloon to support infusion at a specific region. It is neither a peripherally-inserted central venous catheter, dedicated occluding catheter, nor superselective small vessel microcatheter. This is a single-use device.
