System Description
The AtriClip Flex-V LAA Exclusion System contains a V Clip for exclusion of the heart’s left atrial appendage (LAA). Preclinical animal studies (Kamohara 2005, 2006) demonstrate that complete exclusion with the Clip also results in acute and chronic electrical isolation of the LAA. A human clinical study (Starck 2012) has demonstrated acute electrical isolation. Chronic electrical isolation has not been evaluated in human clinical studies. The AtriClip Flex-V LAA Exclusion System is a delivery and deployment device preloaded with a V Clip. The V Clip is preloaded on a disposable Clip applier. The V Clip is a permanent implant; device lifetime is equal to patient lifetime. The Clip was determined to be MR Conditional per the requirements of standard ASTM F2503-20. The AtriClip Flex-V LAA Exclusion System is used to deliver a preloaded Clip to the target LAA site. The Clip is a sterile, permanent implant composed of Grade 5 Titanium and covered in a knit-braided Polyethylene Terephthalate fabric that contains a small fraction of titanium dioxide. The Flex-V LAA Exclusion System with preloaded V Clip is not made with natural rubber latex and does not contain phthalates. Detailed materials information for implanted V Clip sizes 35mm to 50mm are below:

INSTRUCTIONS FOR USE

Surgeon judgment, with the assistance of the Guide, should determine what size Clip to apply. This IFU is designed to assist in using this product. It is not a reference to surgical techniques.

CLIP SELECTION

WARNING!
Carefully consider any presurgical treatment the patient may have undergone when selecting Clip size. Preoperative radiotherapy may result in tissue changes. These changes may, for example, cause the tissue thickness to exceed the indicated range for the selected Clip size. Failure to correctly size the Clip may result in: tissue trauma, dehiscence, tissue tearing, displacement, lack of desired hemostasis, and/or incomplete exclusion of the structure.

1. Using the Guide, determine the correct selection of the V Clip (See Figure 2). Clip sizes are located on the device package.
   Labeled Clip Size| LAA Size Range
   ---|---
   35 mm| 29 – 35 mm (1.14 – 1.38 in)
   40 mm| 34 – 40 mm (1.34 – 1.57 in)
   45 mm| 39 – 45 mm (1.54 – 1.77 in)
   50 mm| 44 – 50 mm (1.73 – 1.97 in)

WARNINGS! Do not use on an LAA less than 29 mm (1.14 in) in width and 1 mm (0.04 in) wall thickness. Doing so may result in: tissue trauma, dehiscence, tissue tearing, displacement, and/or lack of desired hemostasis. Do not use on a LAA greater than 50 mm (1.97 in) when tissue is uncompressed. Doing so may result in incomplete exclusion of the structure.

2. Using a sterile technique, remove the AtriClip Flex-V LAA Exclusion System from its packaging.
   WARNING! If the sterile package is damaged and/or the sterile barrier is breached, discard the device and DO NOT USE to avoid the risk of patient infection.
   CAUTION: Do not drop the device as this may induce damage to the device. If the device is dropped, do not use. Replace with a new device.

3. Using the Activation Lever on the Handle, gently open and close the Clip to ensure proper function.
   SHAFT BENDING
   CAUTION: Do not grasp End Effector to apply bend to Shaft, as this may result in damage to the device. Apply bend by gently concentrating force under both thumbs. The entire length of Shaft is malleable and intended for adjustments up to 45 degrees in any direction. Excessive bending or kinking of the Shaft may affect device performance. Do not attempt to twist the device End Effector, as this may cause damage to the device.

4. The AtriClip Flex-V contains a malleable Shaft that may be reshaped to aid in accessing the LAA. Apply gentle pressure to shape the device Shaft as required for anatomical variations (See Figure 3).
   CAUTION: Do not attempt to rotate the device End Effector without pulling it out of the locked position. Force applied while in the locked position may cause damage to the device.

5. By pulling the Shaft Rotation Knob forward (distal) and twisting it to the left or right, the End Effector of the Flex-V LAA Exclusion System may be manually rotated side-to-side. The Clip and End Effector can rotate 90° left or right in 45° increments to account for user preference or variations in the patient’s anatomy (See Figure 4).

6. To lock the End Effector in position, release forward pressure on the Shaft Rotation Knob and ensure that it is seated into position.
   CLIP POSITIONING
   WARNING! Position and deploy Clip in a manner that provides direct visualization of all tissues being accessed. Direct visualization, in this context, requires that the surgeon can see heart directly, with or without assistance from a camera, endoscope, etc., or other appropriate viewing technologies. Poor visualization may result in suboptimal placement and damage or obstruction of surrounding structures.

7. With the Clip in the closed position, maneuver the AtriClip Flex-V LAA Exclusion System into the targeted dissection plane.

8. Gently open the Clip by squeezing the Activation Lever (See Figure 5).
   NOTE: Maintain pressure on the Activation Lever to hold the Clip open. This device does not contain an automatic locking function.

9. Gently position the Clip at the base of the LAA (See Figure 6).

10. Position the Clip in a manner that provides clear visualization of all tissues being accessed.

11. While the Clip is still affixed to the Deployment Device, ensure that no surrounding structures interfere with or are damaged by the Clip, and that the Clip is placed correctly.

12. After the Clip is positioned correctly, slowly release the Activation Lever to allow the Clip to close.

13. If the Clip is not placed correctly, gently open the Clip and reposition as needed.
    DEPLOYMENT
    WARNING! Carefully evaluate Clip position, tissue thickness, and tissue width before Clip deployment. To determine the appropriate Clip size, refer to the Guide Instructions for Use. Failure to correctly size or deploy the Clip may result in: tissue trauma, dehiscence, tissue tearing, displacement, and/or lack of desired hemostasis. Unless medically necessary, do not attempt to reposition or remove the Clip after deployment. This may result in tissue damage or tearing.

14. Deploy the Clip by pulling the Deployment Trigger at the nose of the Handle (See Figure 7).
    NOTE: Only pull the Deployment Trigger when the Clip is properly positioned over the LAA. Pulling the Deployment Trigger permanently releases the Clip from the applier.
    NOTE: An audible “click” will be heard when the Deployment Trigger has been activated.
    CAUTION : Take care to minimize manipulation of the LAA and Clip after Clip deployment.

15. Carefully remove the End Effector from the LAA leaving the Clip and attachment suture behind (See Figure 8).
    NOTE : After pulling the Deployment Trigger, the AtriClip LAA Exclusion System cannot be used to reposition or remove the Clip.
