The summary describes a reprocessed electrosurgical instrument that uses RF energy for sealing and a mechanical blade for cutting. There is no mention of AI or ML in the device description, intended use, or performance studies. The focus is on the physical mechanism and energy delivery, not intelligent processing of data.
Yes
This device is clearly described as a bipolar electrosurgical instrument used in surgical procedures for ligation and division of vessels and tissues, which are therapeutic actions.
No
The device is described as a surgical instrument for ligation and division of vessels and tissue, which is a therapeutic function, not a diagnostic one.
No
The device is a physical electrosurgical instrument with mechanical components (jaws, blade, trigger, activation button) and connects to a generator via a cable. It is not solely software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for use in open surgical procedures for the ligation and division of vessels, tissue bundles, and lymphatics. This is a surgical intervention performed directly on the patient's body.
- Device Description: The description details a bipolar electrosurgical instrument with jaws and a blade used to apply energy and cut tissue during surgery.
- Lack of In Vitro Activity: There is no mention of the device being used to examine specimens (like blood, urine, or tissue) outside of the body to provide information about a patient's health. IVDs are designed for testing samples in a laboratory or similar setting.
The device is a surgical tool used in vivo (within the living body) during a procedure, not a diagnostic tool used in vitro (outside the living body) to analyze samples.

Intended Use / Indications for Use
The Reprocessed LF1212A LigaSure Sealer/Divider is a bipolar electrosurgical instrument intended for use in open surgical procedures where ligation and division of vessels, tissue bundles, and lymphatics is desired. The LigaSure Sealer/ Divider can be used on vessels (arteries and veins) up to and including 7 mm. It is indicated for use in general surgery and in such surgical specialties as urologic, thoracic, plastic, and reconstructive. Procedure may include, but are not limited to, bowel resections, gall bladder procedures, Nissen fundoplication, and adhesiolysis.
The instrument is also indicated for open ENT procedures in adults (thyroidectomy, radical neck dissection, parotidectomy, and tonsillectomy) for ligation of vessels, lymphatics and tissue bundles 2-3 mm away from unintended thermally-sensitive structures such as nerves and parathyroid glands.
The LigaSure system has not been shown to be effective for tubal coagulation for sterilization procedures. Do not use the LigaSure system for these procedures.

Device Description
The Reprocessed LigaSure Curved, Small Jaw, Open Sealer/Divider (LF1212A) is a bipolar electrosurgical instrument intended for use in open surgical procedures where ligation and division of vessels, tissue bundles, and lymphatics is desired. 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 following controls are located on the device:
- Scissor like design 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. The button has two stages that provide tactile feedback to the user. The first stage button click does not apply energy, whereas the second stage click begins energy application.
- . A trigger for actuating the blade.
All controls can be operated with either the right or left hand. Vessel sealing can be initiated using the activation button or utilizing a footswitch connected to the generator. The instrument attached to the generator via a cable with a connector that identifies the instrument type to the generator.
The instrument is compatible with the Covidien ForceTriad Energy Platform and Valleylab FT10 Energy Platform.
The scope of the submission only includes the addition of a second reprocessing cycle to the previously cleared Reprocessed LigaSure Curved, Small Jaw, Open Sealer/Divider (K220411) and not the Covidien ForceTriad Energy Platform or Valleylab FT10 Energy Platform that are used to power the device, or the footswitch that connects to the generator. Stryker Sustainability Solutions does not reprocess or market the generators or footswitch.
