The Twin-Pass catheters are intended to be used in conjunction with steerable guidewires in order to access discrete regions of the coronary and peripheral arterial vasculature, to facilitate placement and exchange of guidewires and other interventional devices, and for use during two guidewire procedures. The Twin-Pass .023” catheters are also used to sub selectively infuse/deliver diagnostic or therapeutic agents and to measure intra-arterial pressure within the peripheral vasculature.
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.
