The Pantheris System is intended to remove plaque (atherectomy) from partially occluded vessels in the peripheral vasculature with a reference diameter of 3.0 mm to 7.0 mm, using OCT-assisted orientation as an adjunct to fluoroscopy. The Pantheris System is NOT intended for use in the iliac, coronary, cerebral, renal or carotid vasculature.
The Pantheris System consists of the Pantheris Catheter (packaged with the Flush Fixture), Lightbox Sled (referred to as Sled), the Lightbox HS Imaging Console, the Lightbox Umbilical (referred to as Umbilical), Sterile Drape (accessory) and the Occlusion Sheath (optional accessory). The Pantheris System combines the use of Avinger's Optical Coherence Tomography (OCT) technology with peripheral vascular atherectomy capabilities.
The Pantheris Catheter has a working length of 130 cm and is a sterile, singleuse device that is compatible with 8F sheaths and 0.014" guidewires. The Pantheris Catheter consists of an imaging assembly, a rotating cutter, an apposition mechanism (balloon) and a flexible, tiltable nosecone. It also incorporates an Optical Fiber that allows for real-time OCT guided directional atherectomy during the procedure. The Pantheris Catheter and optional Occlusion Sheath accessory are provided sterile and are intended for single-use only.
The Pantheris Catheter is connected to the Lightbox HS Imaging Console via the Sled and the Umbilical. The Sled provides optical and rotational power to the Pantheris Catheter. The Umbilical is a 3-meter long optical and electrical extension cable that connects the Sled to the Lightbox HS Imaging Console.
The Lightbox HS Imaging Console is an optical transceiver, transmitting light to the intraluminal environment through the optical fiber on the Pantheris Catheter and receiving and interpreting the signal from the tissue using a PC-based processing system. The Lightbox provides a visualization platform that allows for real-time OCT-assisted directional atherectomy. The Lightbox HS Imaging Console consists of a cart with two monitors; a PC based processing system, an isolation transformer and an OCT system.
