The pNOVUS 21 Microcatheter is intended for delivering diagnostic agents (such as contrast media), therapeutic agents (such as antiplatelet or vasodilating drugs) and non-liquid interventional devices (such as thrombectomy devices) to intra- and extracranial brain-supplying arteries and intra- and extracranial brain-draining veins.pNOVUS 21 is generally inserted either through a sheath or guide-catheter. Arterial access is typically gained in the femoral, brachial, or radial artery but other access sites (e.g. carotid artery) may be used in rare occasions. Most common sites for venous access are the femoral, brachial, basilic or cephalic vein, but other accessible veins may be used depending on the condition to be treated.
A sterile, small-diameter, single-lumen, flexible tube designed for the controlled infusion of fluids (e.g., thrombolytics, diagnostic contrast media) into superselective small vessels (including intracranial, peripheral, or occluded coronary vasculature) for angiography/treatment, and typically also for the delivery of devices (e.g., embolization implants, guidewires) into tortuous vessels or across tight lesions. It may include an ultrasound transducer, a thermal sensor, and a hole for guidewire placement located at the distal tip. It is not a guide-catheter (i.e., is not intended to deliver other catheters or therapeutic leads directly through its lumen). This is a single-use device.
