Indications for Use
CONMED CleanSeal Vessel Sealers are intended to be used in open and minimally invasive procedures for the ligation and division of tissue bundles, lymphatics, and vessels up to and including 6 mm vessels (arteries, veins, pulmonary arteries, pulmonary veins). The handpiece is indicated for use in gynecological and general surgical procedures, including urologic, thoracic, and vascular. These procedures include, but are not limited to, hysterectomies, colectomies, Nissen fundoplication, and adhesiolysis. CleanSeal vessel sealer has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures. Do not use CleanSeal vessel sealer for these procedures.
Device Story
CleanSeal Advanced Bipolar Vessel Sealer Maryland is a sterile, single-use bipolar electrosurgical handpiece; used with compatible MEP-1 generator. Device features double-action non-stick coated jaws, three shaft lengths (23cm, 37cm, 44cm), and a one-hand controlled handle with latchable lever. User operates device in open or minimally invasive surgical settings. Mechanism: RF energy applied to tissue/vessels between jaws; integrated stainless-steel knife for transection. Rotator knob allows 360° shaft rotation. Smart chip in ESU plug communicates parameters to generator. Healthcare provider uses device to seal and divide vascular structures; benefits include effective hemostasis and tissue management during procedures like hysterectomies and colectomies.
Clinical Evidence

# E. Device Description
CleanSeal Advanced Bipolar Vessel Sealer Maryland is designed to be used, with a compatible MEP-1 electrosurqical generator, in open and minimally invasive procedures for the ligation and division of tissue bundles, lymphatics, and vessels up to and including 6 mm arteries and veins. They are sterile, single use bipolar vessel sealing hand pieces featuring double action non-stick coated jaws, three shaft length options, a one-hand controlled handle with latchable lever. The instrument creates a seal by application of radio frequency (RF) electrosurgical energy to vascular structures or tissue bundles interposed between the jaws.
## F. Intended Use/ Indications for Use
CONMED CleanSeal Vessel Sealers are intended to be used in open and minimally invasive procedures for the ligation and division of tissue bundles, and vessels up to and including 6 mm vessels (arteries, veins, pulmonary arteries, pulmonary veins). The handpiece is indicated for use in gynecological and general surqical procedures, including urologic, thoracic, and vascular. These procedures include, but are not limited to, hysterectomies, colectomies, Nissen fundoplication, and adhesiolysis. CleanSeal vessel sealer has not been shown to be effective for tubal sterilization or tubal coagulation for sterilization procedures. Do not use CleanSeal vessel sealer for these procedures.
## G. Technological Characteristics
CleanSeal Advanced Bipolar Vessel Sealers Maryland (23cm, 37cm and 44cm) connect to the CleanSeal/Bipolar Resection port on MEP-1 via a three-prong ESU plug with a smart chip containing unique parameters specific to the handpiece model. A hand actuated lever allows the user to open or close the instrument jaws during vessel sealing and cutting. An activation button is incorporated into the body of the handle. When connected to MEP-1 and the jaws are shut, the activation button can be pressed to allow the ESU to deliver energy to the CleanSeal Maryland vessel sealer. The cut trigger allows for the transection of tissue, when the jaws are shut, through the deployment of a stainless-steel knife. A rotator knob on the handle allows for 360° rotation of the shaft to position the jaw accurately on the targeted tissue or vessel. The CleanSeal Maryland comes in three shaft lengths (23 cm, 37 cm, and 44 cm). The device is single use.
## H. Performance Testing
CleanSeal Advanced Bipolar Vessel Sealers Maryland have been tested according to the applicable requirements listed in FDA guidance "Premarket Notification (510(k)) Submissions for Electrosurgical Devices for General Surgery" and "Premarket Notification (510(k)) Submissions for Bipolar Electrosurgical Vessel Sealers for General Surgery". Benchtop and ex-vivo comparison testing, in-vivo simulated use testing, and chronic animal studies support that the CleanSeal Maryland is substantially equivalent to the Ligasure Maryland Jaw nano-coated (primary predicate), Ligasure Maryland Jaw thoracic nano-coated (secondary predicate) and the CleanSeal Vessel Sealer 5mm (reference device) in intended use, technology, and system performance.
Mechanical and electrical verification activities demonstrate the CleanSeal Advanced Bipolar Vessel Sealers Maryland complies with the applicable sections of AAMI/ANSI ES60601-1, IEC 60601-2-2 and 60601-2-18 . Risk management activities in accordance with ISO 14971 demonstrate the risks associated with the use of CleanSeal Maryland is mitigated to an acceptable level. Analyses of these activities conclude the benefits associated with the use of the CleanSeal Maryland outweigh the residual risks.
{6}------------------------------------------------
#### Biocompatibility Test -
The CleanSeal Advanced Bipolar Vessel Sealer Marylance with 2020 FDA Guidance of Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process". The biological test results support that the CleanSeal Maryland met acceptance criteria for all biocompatibility test endpoints.
# J. Chronic Animal Study
A chronic animal study was conducted according to FDA guidance, "Premarket Notification (510(k)) Submissions for Bipolar Electrosurgical Vessel Sealers for General Surgery" Guidance for Industry and Food and Drug Administration Staff, issued on August 15, 2016; and "Premarket Notification (510(k)) Submissions for Electrosurgical Devices for General Surgery" Guidance for Industry and Food and Drug Administration Staff, issued on March 9, 2020. The first test evaluated, in a porcine model, the performance of the CleanSeal Maryland with MEP-1 (Test system) in comparison to the LigaSure Maryland with Nanocoating and Valleylab FT10 ESU. (Primary predicate). After 21 days in the porcine model, the treatment of vascular structures (i.e., arteries, veins, and arterio-venous [AV] bundles) with the test system was determined to result in the effective sealing of treated vessels. The second test evaluated, in a canine model, the performance of the CleanSeal Maryland with MEP-1 (Test system) in comparison to the LigaSure Maryland thoracic with Nanocoating and Valleylab FT10 ESU, (Secondary predicate). After 21 days in the canine model, the treatment of vascular structures in the thoracic cavity (i.e., Pulmonary arteries, veins, and arterio-venous [A/V] bundles) with the test system was determined to result in the effective sealing of treated vessels.
# K. Shelf Life
CleanSeal Advanced Bipolar Vessel Sealer Maryland has a one-year shelf-life based on results of an accelerated aging study. The shelf-life study evaluated the device specifications and package integrity/sterile barrier. The device met all acceptance criteria to support a shelf-life of one year.
## L. Substantial Equivalence
The differences between the predicate devices and the proposed device do not raise any new risks of safety or efficacy. Supporting information per this premarket submission confirms that the CleanSeal Advanced Bipolar Vessel Sealer Maryland is safe and effective for its intended use and is substantially equivalent in design, intended use, principals of operation, and technical characteristics to the LigaSure Maryland Jaw Sealer/Divider One-step Sealing, Nano-coated, LigaSure Maryland Jaw Thoracic Sealer/Divider, One-step sealing Nano-coated and CleanSeal 5mm Vessel Sealer.
