1 General System Description

The Apollo Endosurgery OverStitchTM EndoscopicSuturing System (ESS) provides physicians theability to perform tissue apposition within theGastrointestinal (GI) Tract. Additionally, the systemallows the surgeon to ‘reload’ the suture without theneed for removing the endoscope.

The ESS works by delivering a proprietary Anchorand Suture through the channel of the endoscopeand passing both to the Suturing Arm. As necessary,a tissue retractor can be passed down the scope’ssecond channel to pull tissue into the plane of theESS’s Suturing Arm. The ESS has the ability to passthe Anchor through a full thickness bite of tissue.This process can be repeated for placement of acontinuous row of running stitches or terminatedfor an interrupted stitch. To secure each Suture aCinch is passed down the scope’s primary channeland the user deploys the Cinch while applying thedesired amount of suture tension.

The OverStitch product family is comprised of threedevices which include the Endoscopic SuturingSystem (ESS), a choice of Suture, and a SutureCinch. All devices are delivered sterile and sealedin protective packaging.

The Endoscopic Suturing System is comprised of aSystem Handle, an End Cap, and an Anchor Exchange.The End Cap contains a Suturing Arm which tradesan Anchor with the Anchor Exchange and performsthe stitching operations. The opening and closingof the Suturing Arm is controlled by the Handle Grip.The system contains a Retention Wire that ensuresthe End Cap does not inadvertently disengage fromthe tip of the endoscope. The Anchor Exchangeallows for the endoscopic loading and recapture ofan Anchor and Suture.

The OverStitch Sutures consist of an Anchor andSuture combination that was designed to specificallywork with the Endoscopic Suturing System. TheSuture system was also designed to allow theAnchor to serve as a t-tag, securing the Sutureafter placement. Each Suture is delivered in aSuture Cassette for ease of handling. The Sutureis offered in a combination of a 2-0 or 3-0 sizes inbraided absorbable suture (PGA) or monofilamentnonabsorbable (Polypropylene). The Sutures meetabsorbable and nonabsorbable surgical suturerequirements established by the United StatesPharmacopeia (U.S.P.).

Polyglycolic Acid (PGA) Suture is a coated, braidedsynthetic absorbable surgical suture. It is violetin color and is coated for lubricity. The in-vitroretention strength is 73.0% ± 6.0% at 14 days andis 45.0% ± 6.5% at 21 days. The material absorbsby hydrolysis in 60 to 90 days with virtually notissue reaction. The material is supplied sterile.

Polypropylene Suture is a nonabsorbable surgicalsuture that is blue in color. The polypropylene sutureelicits a minimal acute inflammatory reaction intissues, which is followed by gradual encapsulationof the suture of fibrous connective tissue. Thesesutures are nonabsorbable and no significantchange in strength retention is known to occur in vivo.

The Suture Cinch consists of an instrument todeliver an implantable suture cinch that maintainsthe desired suture tension.

2 Intended Use

The Apollo Endosurgery Endoscopic Suture Systemis intended for endoscopic placement of suture(s)and approximation of soft tissue.

3 Contraindications

Contraindications include those specific to use of anendoscopic suturing system, and any endoscopicprocedure, which may include, but not limited to,the following:

• This system is not for use when endoscopictechniques generally are contraindicated.

• This system is not for use with malignanttissue.

• Absorbable sutures, should not be usedwhere extended approximation of tissueis required.

4 Warnings

• Do not use a device where the integrity ofthe sterile packaging has been compro-mised or if the device appears damaged.

• Only physicians possessing sufficient skilland experience in similar or the sametechniques should perform endoscopicprocedures.

• Do not attempt to open the Suturing Armin a confined space. Ensure adequateclearance for the fully opened SuturingArm prior to use

• When intubating or extubating with theEndoscopic Suturing System, ensure thatthe endoscope body and the ActuationCatheter are retracted together.

• Ensure that the Handle Grip of theEndoscopic Suturing System is closed andlocked during intubation and extubation.

• Do not force the Anchor Exchange if resistanceis encountered during introduction throughthe scope. Reduce the endoscope angulationuntil the device passes smoothly.

• Ensure that adequate Suture tension ismaintained during introduction of theSuture Cinch.

• With the device installed on the scope,accessories designed to hold the endoscopealone may no longer securely hold onto theendoscope.

• Discard open, unused Sutures.• Users should be familiar with surgical

procedures and techniques involvingabsorbable sutures before employingSynthetic Absorbable Sutures for woundclosure, as the risk of wound dehiscencemay vary with the site of application andthe suture material used.

• Do not remove the Safety Tab from theSuture Cinch handle until the Suture Cinchis ready for final deployment; early removalof the Safety Tab will result in prematureengagement of the Suture Cinch ontothe Suture

• Do not re-sterilize or reprocess

5 Precautions

• All packaged product should be stored in acool, dark, dry place.

• The System may only be used if purchasedfrom Apollo Endosurgery, Inc. or one of itsauthorized agents.

• With the Endoscopic Suturing Systeminstalled, the endoscope’s primary channeleffectively becomes a 3.4-mm channel, andthe secondary channel effectively becomesa 2.3-mm channel.

• Use in the Lower Gastrointestinal tract isonly recommended when accompanied byan access port.

• Use of the Endoscopic Suturing System andthe system components has not been studiedin the esophagus. There is no data on file toshow safety or efficacy of the product in thisanatomy.

• Use caution when maneuvering the systemwhen loaded with an Anchor to avoidunintended contact with delicate tissue.

• The contents of the system and the systemas a whole are not intended for reprocessingor re-sterilization.

Steps to Resolve Condition

First line of defense:1. Ensure the System Handle is shuttled all of the way out2. Open the System Handle by squeezing the Handle Grip – ensure

the Handle Grip Lock is disengaged3. Gently steer the endoscope tip to allow the End Cap to open naturally

Severe Entrapment:Eject the End Cap and remove by the following means:

1. Follow the instructions on the prior section to insert an overtubeand advance it to the End Cap.

2. Once the End Cap is visible through the endoscope, separate theEnd Cap assembly from the tissue using standard endoscopictechniques.

3. Pull the End Cap into the overtube and remove using standardendoscopic techniques.

Steps to Resolve Condition

1. Pass a compatible grasper down the secondary channel andgrasp the Suture. While holding the graspers on the Suture, pullthe Cinch out of the endoscope and the System Handle. If theCinch cannot be removed from the system, continue to step 2.

2. Regardless of the location of the Cinch, ensure that Cinch hasbeen fully deployed. If not, deploy the Cinch per the “Cinching”section of the IFU. If the Cinch cannot be removed from the systemafter deployment, continue to step 3.

3. Remove any accessory from the endoscope’s secondary channeland pass the compatible loop cutter down the secondary channel.Use the loop cutter to cut the Suture between the surgical site andthe Cinch. This will free the system for removal.
