BEFORE USING PRODUCT READ THE FOLLOWING INFORMATION THOROUGHLY

IMPORTANT!
This booklet is designed to assist in using this product. It is not a reference to surgical techniques.
INDICATION FOR USE
The AtriClip LAA Exclusion System is indicated for the occlusion of the heart’s left atrial appendage.

CONTRAINDICATIONS

Do not use this device as a contraceptive tubal occlusion device.
Do not use this device if the patient has a known allergy to Nitinol (nickel titanium alloy).

WARNINGS ****

Do not attempt to reposition or remove the Clip after deployment. This may result in tissue damage or tearing.
Use this device only as intended.
Do not use on tissue which, in the opinion of the surgeon, would not be able to tolerate conventional suture materials or
conventional closure techniques (such as surgical stapling).
Carefully evaluate Clip position, tissue thickness, and tissue width prior to Clip deployment.
To determine appropriate Clip size, refer to the Cosgrove-Gillinov Selection 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 homeostasis.
Do not use on a LAA less than 29mm in width and 1.0mm wall thickness.
Do not use on a LAA greater than 50mm when tissue is uncompressed.
Do not use this device if the patient has sensitivity to Nickel (nickel titanium alloy).

**** PRECAUTIONS

Read all instructions carefully for the AtriClip LAA Exclusion System. Failure to properly follow instructions may result in improper functioning of the device.
Use of the device should be limited to properly trained and qualified medical personnel.
Note that variations in specific procedures may occur due to individual physician techniques and patient anatomy.
Do not drop or toss the device as this may induce damage to the device. If the device is dropped, do not use. Replace with a new device.
DO NOT RESTERILIZE. The AtriClip LAA Exclusion System is provided STERILE and is intended for SINGLE use only.
Re-sterilization may cause loss of function or injury to patient.
Carefully consider any pre-surgical treatment the patient may have undergone and in corresponding selection of Clip size.
Preoperative radiotherapy may result in changes to tissue. These changes may, for example, cause the tissue thickness to exceed the indicated range for the selected Clip size.
Do not modify this instrument. Use of a modified device may result in improper instrument function. AtriCure, Inc. makes no claim or representation as to the performance characteristics of this product if any modifications have been made to the AtriClip LAA Exclusion System.
Do not kink or excessively bend the shaft as this may affect device performance.
Evacuate thrombus from the LAA prior to Clip application as with other conventional LAA occlusion surgical techniques. Evaluating for the presence of thrombus should be done per the surgeon’s discretion and standard of care.
Position and deploy Clip under direct visualization. Poor visualization may result in suboptimal placement.
Take care to minimize manipulation of the LAA and Clip after Clip deployment.
It is recommended that the Clip be deployed in a dry field.
Do not use the Clip in temperatures below 20 °C. Application of the Clip in temperatures below 20 °C may affect device performance.
Do not attempt to articulate the End Effector while in the locked position. Force applied while in the locked position may cause damage to the device.

INSTRUCTIONS FOR USE

Surgeon judgment, with the assistance of the Gillinov-Cosgrove Selection Guide, should determine what size Clip to apply.

CLIP SELECTION

Using the Gillinov-Cosgrove Selection Guide, determine correct selection of the Gillinov-Cosgrove LAA Clip (See Figure 2).

Clip sizes are located on the device package. Clip Size| LAA Size Range
---|---
35 mm| 29 – 35 mm
40 mm| 34 – 40 mm
45 mm| 39 – 45 mm
50 mm| 44 – 50 mm
Using sterile technique, remove the AtriClip LAA Exclusion System from its packaging.
Using the Activation Lever on the handle, gently open and close the Clip to assure proper function.
Caution : Do not open and close the Clip more than 3 times with the activation lever prior to deployment.

ARTICULATION OF END EFFECTOR

By pushing down and pulling the Articulation Lock (10) backwards (proximal), the End Effector (4) of the AtriClip LAA Exclusion System may be manually articulated up and down and side-to-side by either the articulation levers or pressing on the end effector. The Clip (5) and End Effector (4) can articulate 30° left or right and 30° up or down to take into account anatomical variations in the patient’s anatomy (See Figure 3).
To lock the End-Effector (4) in position, press the Articulation Lock (10) forward.

CLIP POSITIONING

Maneuver the AtriClip LAA Exclusion System into the targeted dissection plane (See Figure 4).
Gently open the Clip by squeezing the Activation Lever (2).
NOTE : The Clip automatically locks in the fully open position by means of a Locking Trigger on the handle of the device. The lock can be disengaged by pressing the Lever Release Trigger (3).
Orient the Clip applier with pre-loaded Clip at the tip of LAA with the loops at the ends of the Clip pointed away from the LAA.
Gently position the Clip at the base of the LAA (See Figure 5).
Position the Clip in a manner that provides clear visualization of all tissues being accessed.
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.
If the Clip is not placed correctly, gently open the Clip and reposition as needed.
After the Clip is positioned correctly, grasp the Activation Lever (2) and depress the Lever Release Trigger (3) and slowly release the Activation Lever allowing the Clip to close.

DEPLOYMENT

Deploy the Clip by slowly pulling the Deployment Tab (11) at the proximal end of the handle. NOTE: The Deployment Tab (11) with steel cables may be completely removed from the end of the Handle (See Figure 6).
Unlock the end effector articulation (10) and carefully remove it from the LAA leaving the Clip and attachment suture behind (See Figure 7).

Caution : After pulling the Deployment Tab, the AtriClip LAA Exclusion System cannot be used to reposition the Clip.
Discard the deployment device after use. Follow local governing ordinances and recycling plans regarding disposal or recycling of device components.

HANDLING INFORMATION: GILLINOV- COSGROVE LAA CLIP

MRI SAFETY INFORMATION

MR Conditional

Non-clinical testing demonstrated that the AOD1 (Annular Occlusion Device) clip is MR Conditional. A patient with this device can be scanned safely in an MR system immediately after placement under the following conditions:

Static magnetic field of 1.5Tesla and 3 Tesla, only
Maximum spatial gradient magnetic field of 4,000 gauss/cm (40 T/m)(extrapolated) or less
Maximum MR system reported, whole body averaged specific absorption rate (SAR) of 4 W/kg for 15 minutes of scanning (i.e., per pulse sequence) in the First Level Controlled Operating Mode of operation for the MR system
Under the scan conditions defined for the AOD1 Clip is expected to produce a maximum temperature rise of 2.9 °C after 15 minutes of continuous scanning (i.e., per pulse sequence).

ARTIFACT INFORMATION

In non-clinical testing, the image artifact caused by the AOD1 Clip extends approximately 10 mm from the AOD1 Clip when imaged using a gradient echo pulse sequence and a 3 Tesla MR system.
