The Sniper is a dual lumen, 110cm, straight tip catheter comprised of an inner guidewire/infusion lumen and an outer, annular lumen to inflate and deflate the balloon. The guidewire/infusion port may be used to inject contrast media or therapeutic agents following removal of the guidewire. The catheter has two radiopaque markers: one marker at the distal tip and another in the center of the balloon.
A sterile, flexible tube designed primarily to enable the delivery of diagnostic or therapeutic solutions into the peripheral vasculature; some types may in addition be applied to coronary or pulmonary vasculature. It is percutaneously introduced [e.g., through a guide catheter, or over-the-wire (OTW)], 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 microcatheter for access into superselective small vessels. This is a single-use device.
