The device is a bipolar electrosurgical instrument, which is a physical hardware device used in surgery. The description details its physical components and function, not just software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood, tissue, and urine, from the human body to provide information for diagnostic, monitoring, or compatibility purposes.
- Device Function: The Reprocessed LigaSure Sealer/Divider is a surgical instrument used during surgical procedures to seal and divide vessels and tissue using electrosurgical energy. It directly interacts with the patient's body during surgery.
- Intended Use: The intended use clearly states it's for use in "minimally invasive or open surgical procedures where ligation of vessels, tissue bundles, and lymphatics is desired." This is an in vivo (within the living body) application, not in vitro (in a test tube or lab setting).
Therefore, the function and intended use of this device classify it as a surgical instrument, not an In Vitro Diagnostic.

The instrument is intended to be used with Covidien electrosurgical generators that include vessel sealing capability. The instrument can be used on vessels (arteries and veins) up to and including 7 mm. The instrument creates a seal by application of radiofrequency (RF) electrosurgical energy to vascular structures (vessels and lymphatics) or tissue bundles interposed between the jaws of the instrument. A blade within the instrument is surgeon actuated to divide tissue. The outer diameter of the instrument shaft is 5 mm with a working length of 23 cm, 37 cm, or 44 cm. The following controls are located on the instrument handle:
- . A lever for opening and closing the instrument jaws and activating RF energy. The mechanism must be held in the closed position during vessel sealing and cutting.
- . An activation button at the bottom of the handle for generator power to initiate vessel sealing.
- A trigger for actuating the cutter. The cutter can only be actuated when the jaws are closed.
- . A rotation wheel to rotate the instrument jaws.
