Intended Use

The Reprocessed LF1212A LigaSure Sealer/Divider is a bipolar electrosurgical instrument intended for use in open surgical procedures where ligation 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 (thyroidectorny, radical neck dissection, parotidectorny, 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 sterilization or tubal coagulation for sterilization procedures. Do not use the LigaSure system for these procedures.

Device Story

Bipolar electrosurgical instrument for open surgery; used with compatible electrosurgical generators (ForceTriad, Valleylab FT10). Device inputs: RF energy from generator; manual user force. Mechanism: RF energy applied to vessels/tissue bundles between jaws to create seal; surgeon-actuated blade divides tissue. Operated by surgeon in OR. Output: Sealed and divided vessels/tissue. Benefits: Hemostasis and tissue division in various surgical specialties. Reprocessed device maintains original mechanical design, materials, and size. Device features scissor-like handle, activation button with two-stage tactile feedback, and blade trigger. Compatible with right or left-hand use.

Clinical Evidence

Bench testing and preclinical animal studies performed. Bench testing included biocompatibility, sterilization validation, electrical safety (IEC 60601-1, IEC 60601-1-2, IEC 60601-2-2), and functional performance (burst pressure, jaw temperature, seal/divide capability on 1-7mm vessels). Preclinical animal studies (acute and chronic survival) evaluated thermal spread and hemostasis efficacy.

Technological Characteristics

Bipolar electrosurgical instrument; 19cm length; 16.5mm curved jaw. Energy source: external electrosurgical generator (RF). Mechanical actuation for jaw closure and blade deployment. Reprocessed device; sterilization method not specified. Complies with IEC 60601-1, IEC 60601-1-2, and IEC 60601-2-2 standards.

Indications for Use

Indicated for open surgical procedures in adults requiring ligation and division of vessels (up to 7mm), tissue bundles, and lymphatics. Specialties include general, urologic, thoracic, plastic, and reconstructive surgery. ENT indications include thyroidectomy, radical neck dissection, parotidectomy, and tonsillectomy. Contraindicated for tubal coagulation/sterilization.

### 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

{5}------------------------------------------------

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 Enerqy Platform and Valleylab FT10 Energy Platform.

The scope of the submission only includes the Reprocessed LigaSure Curved, Small Jaw, Open Sealer/Divider 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.

## Intended Use:

The Reprocessed LF1212A LigaSure Sealer/Divider is a bipolar electrosurgical instrument intended for use in open surgical procedures where ligation of vessels, tissue bundles, and lymphatics is desired.

- Biocompatibility ●
- Validation of Reprocessing
- Sterilization
- Electrical Safety and Electromagnetic Compatibility
- Functional Performance Tests
- Blade Trigger Actuation Force O
- O Clamp Arm Closing and Seal Button Force
- Clamp Arm Opening Force o
- Clamp Arm Deflection O
- O Jaw Clamp Force
- Blade Excursion O
- Jaw Opening Angle O
- Burst Pressure O
- Maximum Jaw Temperature O
- Device Reliability O
- Functional Attribute Testing O

The functional performance testing involved electrical safety and electromagnetic compatibility testing in accordance with IEC 60601-1, IEC 60601-1-2, and IEC 60601-2-2, and verification/comparative testing (to the predicate device). The bench testing involved evaluation of the device's performance and ability to seal and divide vessels from 1mm to 7mm, including burst pressure, maximum jaw temperature, device functionality, device reliability, and functional attribute tests.

Additionally, preclinical laboratory evaluations in an animal model were performed, which included acute and chronic survival studies were done to evaluate thermal spread and the ability to achieve hemostasis of vessels of the reprocessed device.

# Conclusion:

The results of bench testing and preclinical laboratory evaluations demonstrate that the Reprocessed LigaSure Curved, Small Jaw, Open Sealer/Divider is at least as safe and effective as the predicate and perform as well as the identified legally marketed predicate device as described herein.
