The device description focuses on the chemical composition and physical properties of a solution used for flushing and storing vascular grafts. There is no mention of any software, algorithms, or data processing that would indicate the use of AI or ML.
No.
The duraGraft Vascular Conduit Solution is intended for flushing and storage of saphenous vein grafts, not for treating a disease or condition in a patient. It maintains graft viability during transfer.
No
Explanation: The device description states that DuraGraft Vascular Conduit Solution is a flushing and storage solution for saphenous vein grafts during CABG surgeries. Its purpose is to maintain the viability of the grafts and prevent ischemic injury, not to diagnose a medical condition.
No
The device is a solution, which is a physical substance, not software. The description details its chemical composition, packaging, and physical properties.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for flushing and storage of saphenous vein grafts during surgery. This is a direct interaction with a biological sample (the graft) outside of the body, but it's for the purpose of preserving the sample for later implantation, not for diagnostic testing or obtaining information about a patient's health status.
- Device Description: The description focuses on the chemical composition and physical properties of the solution, designed to maintain the viability of the graft. It does not describe any components or functions related to analyzing a biological sample to provide diagnostic information.
- Lack of Diagnostic Function: There is no mention of the device being used to detect, measure, or analyze any substance or characteristic in a biological sample for the purpose of diagnosis, monitoring, or screening.
- No Mention of Diagnostic Metrics: The performance studies focus on stability and integrity of the solution and its container, not on diagnostic performance metrics like sensitivity, specificity, or AUC.
In summary, DuraGraft Vascular Conduit Solution is a solution used to preserve a biological sample (the vein graft) for surgical purposes. It does not perform any diagnostic function on a biological sample.

Device Description
DuraGraft Vascular Conduit Solution is a single-use, clear, colorless to slightly yellow, non-pyrogenic solution used as a flushing and storage solution during the harvesting and grafting interval in Coronary Artery Bypass Grafting (CABG surgeries). All ingredients are Generally Recognized as Safe (GRAS) and comply with United States Pharmacopoeia (USP) or National Formulary (NF) specifications. No components are of animal or blood origin. The product is aseptically processed using aseptic filling procedures. Stability testing at 25°C supports a shelf life of 2 years at a storage temperature of 20-25°C (controlled room temperature).
The salts in DuraGraft are intended for buffering (to maintain both ionic balance and isotonicity with respect to vascular conduits). The organic components are intended to provide a non-oxidizing environment for vascular conduits and to maintain additional buffering capability and osmolality. The organic components are all normal constituents of blood and are included for their roles in maintaining the extracellular environment of vascular conduits to prevent ischemic injury.
DuraGraft Vascular Conduit Solution is provided in two aseptically processed containers; Solution A and Solution B. Solution A is an aqueous based solution provided in sterile PETG bottles with white HDPE closures. Solution B is an aqueous based solution provided in sterile Type I borosilicate glass vials with bromobutyl rubber stoppers with aluminum crimps. Solution B are mixed at the point of use to generate DuraGraft Vascular Conduit Solution which is the graft storage and flushing solution.
The mixed solution is used at room temperature and has an osmolality of about 305 mOsmol/kg, viscosity of 1.06 cST, a sodium concentration of 155-160 mEq/L (sodium concentration is expressed as a range due to the use of Sodium bicarbonate for pH adjustment of Solution A and is based on review of several (10+) manufacturing batch records), and a potassium concentration of 5.8 mEq/L, and a pH of 7.4 at room temperature.
