Intended Use
The LigaSure Sealer/Divider is a bipolar electrosurgical instrument intended for use in minimally invasive or 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 gerry and such surgical specialties as urologic, vascular, thoracic, and gynecologic. Procedures may include, but are not limited to, Nissen fundoplication, colectomy, cholecystectomy, adhesiolysis, hysterectomy, oophorectomy, etc. 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 LigaSure™ Maryland Jaw Sealer/Divider One-step Sealing, Nano-coated (LF19XX) devices are sterile, single-use, coated, hand-held bipolar vessel sealing devices designed for use with Covidien electrosurgical generators that include vessel sealing capabilities to ligate (seal) and divide (cut) vessels, tissue bundles, and lymphatics clamped between the jaws, grasp tissue, and perform blunt dissection during general surgical procedures (as indicated) using radio frequency (RF) energy. A hand actuated lever allows the user to open or close the instrument jaws during vessel sealing and cutting, with a single activation button incorporated into the body of the handle. The proposed devices come in three shaft lengths (23, 37, and 44 cm) and do not contain software.
More Information

No
The device description explicitly states that the proposed devices "do not contain software," and there are no mentions of AI, ML, or related concepts in the summary.

Yes
The device is intended for use in surgical procedures to ligate (seal) and divide (cut) vessels, tissue bundles, and lymphatics, which are therapeutic actions.

No

This device is a surgical instrument used to seal and divide vessels and tissues, not to diagnose medical conditions or diseases.

No

The device description explicitly states that the proposed devices "do not contain software." It describes a physical, hand-held bipolar vessel sealing device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
  • Device Function: The 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 a surgical intervention, not a diagnostic test performed on a specimen.
  • Device Description: The description details a hand-held bipolar vessel sealing device with jaws and a cutting mechanism, consistent with a surgical tool.
  • Lack of Diagnostic Elements: There is no mention of analyzing biological samples, generating diagnostic results, or providing information for diagnosis based on in vitro testing.

Therefore, the LigaSure Sealer/Divider is a surgical device, not an In Vitro Diagnostic device.

Device Description

The LigaSure™ Maryland Jaw Sealer/Divider One-step Sealing, Nano-coated (LF19XX) devices are sterile, single-use, coated, hand-held bipolar vessel sealing devices designed for use with Covidien electrosurgical generators that include vessel sealing capabilities to ligate (seal) and divide (cut) vessels, tissue bundles, and lymphatics clamped between the jaws, grasp tissue, and perform blunt dissection during general surgical procedures (as indicated) using radio frequency (RF) energy.

A hand actuated lever allows the user to open or close the instrument jaws during vessel sealing and cutting, with a single activation button incorporated into the body of the handle. The proposed devices come in three shaft lengths (23, 37, and 44 cm) and do not contain software.

Indications for Use

The LigaSure Sealer/Divider is a bipolar electrosurgical instrument intended for use in minimally invasive or 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 such surgical specialties as urologic, vascular, thoracic, and gynecologic. Procedures may include, but are not limited to, Nissen fundoplication, colectomy, cholecystectomy, adhesiolysis, hysterectomy, etc.

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.

Comparison of Technological Characteristics with the Predicate Device

The application of radio frequency (RF) energy to target tissue is the fundamental technology for both the subject and predicate devices. A seal is created by application of RF energy to structures (vasculature, lymphatics, and tissue bundles) interposed between the jaws of the instrument. A blade within the instrument is user actuated to divide tissue after the seal is created. At a high level, the subject and predicate devices are based on the following same technological elements:

  • . Unilateral jaws - used to reach target structures (vasculature, lymphatics, and tissue bundles)
  • Lever -closes the jaws to grasp the tissue
  • Activation button - in-line mechanism allows RF energy to be activated by the user
  • Cutting trigger allows user to divide (cut) sealed structures ●

The only differences between the subject and predicate devices are the addition of a non-stick coating to the jaws of the proposed devices and minor manufacturing changes.

Performance Data

The following performance data were provided in support of the substantial equivalence determination.

Biocompatibility

The biocompatibility evaluation for the LigaSure™ Maryland Jaw Sealer/Divider One-step Sealing, Nano-coated devices was conducted in accordance with International Standard ISO 10993-1 "Biological Evaluation Of Medical Devices - Part 1: Evaluation And Testing Within A Risk Management Process," as recognized by FDA. The battery of testing included the following:

  • Cytotoxicity ●
  • Sensitization
  • Intracutaneous Irritation ●
  • . Acute Systemic Toxicity
  • . Materials Mediated Pyrogenicity

5

  • . Hemolysis

Electrical Safety and Electromagnetic Compatibility (EMC)

The system complies with relevant clauses of the ANSI AAMI ES 60601-1 and IEC 60601-2-2 standards for electrical safety and IEC 60601-1-2 standard for EMC.

Mechanical/Functional Testing

Mechanical, electrical, and functional testing was carried out to verify that the proposed devices performed as expected.

  • Jaw force
  • Jaw gap
  • Device resistance, capacitance, and inductance ●
  • . Jaw Hyper-Extension
  • Reliability Use Case Test .

Ex-vivo Vessel Burst Pressure

Ex-vivo burst pressure testing of excised fresh porcine renal arteries and lymphatics was conducted on both the subject and predicate devices to demonstrate bipolar electrosurgical vessel sealing performance.

Acute Animal Study

In the animal study conducted, porcine underwent various procedures to assess acute sealing performance and lateral thermal damage by the subject and predicate devices. The thermal safety of the new device was evaluated. These studies demonstrated that the subject devices are as safe and effective as the predicate devices.

Chronic Animal Study

A chronic study was conducted to assess seal quality over the course of 21 days. All animals survived 21 days post-op and all seals maintained chronic hemostasis.

Clinical Studies

This premarket submission did not rely on the assessment of clinical performance data to demonstrate substantial equivalence.

Summarv

Based on the preclinical performance as documented in the performance testing, the LigaSure™ Maryland Sealer/Divider One-step Sealing, Nano-coated devices were found to have a safety and effectiveness profile that is similar to the predicate devices.

Conclusions

The subject devices have the same indications for use as the legally marketed predicate devices. Furthermore, design changes made to introduce the subject devices do not raise different kinds of safety and effectiveness questions. Verification and validation data support substantial equivalence of the modified LigaSure™ Maryland Sealer/Divider Once-step Sealing, Nanocoated devices to the legally marketed predicate devices.
