INSTRUCTIONS FOR USE
AtriClip PRO® LAA Exclusion System
INDICATION FOR USE
The AtriClip LAA Exclusion System is indicated for the exclusion of the heart’s left atrial appendage, performed under direct visualization and in conjunction with other cardiac surgical procedures.
Direct visualization, in this context, requires that the surgeon is able to see the heart directly, with or without assistance from a camera, endoscope, etc., or other appropriate viewing technologies.
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).
- Do not use this device if evidence of systemic infection, bacterial endocarditis, or in presence of infected operating field.
SYSTEM DESCRIPTION
The AtriClip LAA Exclusion System contains the AtriClip (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 LAA Exclusion System is a delivery and deployment device preloaded with an AtriClip. The Clip is pre-loaded on a disposable Clip applier. The AtriClip 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 F2503-23e1.
The AtriClip 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 2 Titanium and Polyurethane beams, Nitinol springs, and covered in a knit-braided Polyethylene Terephthalate fabric that contains a small fraction of titanium dioxide. The AtriClip LAA Exclusion System with preloaded AtriClip is not made with natural rubber latex and does not contain phthalates. Detailed materials information for implanted Clip sizes 35 mm to 50 mm are below:
| Material | Mass (g) | CAS # |

WARNINGS
Read all instructions carefully for the AtriClip LAA Exclusion System before use and use the device only as intended. Use of the AtriClip LAA Exclusion System should be limited to properly trained and qualified medical personnel. Improper use of this system may lead to device malfunction, failure to provide intended therapy, and/or serious injury to user or patient.
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). Doing so may result in:
tissue trauma, dehiscence, tissue tearing, displacement and/or lack of desired hemostasis.
AtriClip placement that allows blood flow into the LAA may not result in complete exclusion and/or electrical isolation.
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.
Evaluate if thrombus is present in LAA. Management of thrombus is dependent on surgeon’s standard of care. It is not recommended to place Clip on LAA if there is evidence of thrombus in LAA. Doing so may result in serious patient injury.
Do not use the Clip in temperatures below 20°C (68°F). Application of Clip in temperatures below 20°C (68°F) may affect device performance and result in incomplete exclusion of the structure.
The safety and effectiveness of this device in atrial rhythm control management, either alone or in combination with ablative treatment, has not been established.
| WARNING | |
 | This device contains small amounts of Nickel (CAS# 7440-02-0) and Cobalt (CAS# 7440-484). Do not use this device if the patient has sensitivity to Nickel or Cobalt as this may result in an adverse patient reaction. |

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 changes to tissue. 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.
- Using the Guide, determine correct selection of the LAA 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 a 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. - Using sterile technique, remove the AtriClip LAA Exclusion System from its packaging. WARNING
If the sterile package is damaged and/or the sterile barrier is breached, discard 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. - Using the Activation Lever on the handle, gently open and close the Clip to assure proper function. WARNING
Do not open and close the Clip more than 3 times with the Activation Lever prior to deployment. This may lead to incomplete exclusion of the structure. - By pressing the Articulation Release Button and pulling it backwards (proximal) into the unlocked position, the Deployment Loop of the AtriClip LAA Exclusion System may be manually articulated up and down and side-to-side from 0° (inline – as supplied) to ±30° relative to the shaft to aid in the proper placement of the AtriClip to take into account anatomical variations in the patient’s anatomy (See Figure 3).
- To lock the End Effector in position, disengage the Articulation Release Button by pushing down, forward and then releasing. CAUTION: Do not attempt to articulate the Deployment Loop while in the locked position. Force applied while in the locked position may cause damage to the device.
CLIP POSITIONINGWARNING
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 is able to see the 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. CAUTION: Do not kink or bend the Shaft as this may affect device performance. - Maneuver the AtriClip LAA Exclusion System into the targeted dissection plane.
- Gently open the Clip by squeezing the Activation Lever.
NOTE: The Clip can be locked in the open position by means of a locking feature in the Handle of the device.
The lock will engage when the Activation Lever is activated and can be disengaged by gently pressing the Lever Release Button. - Orient the Clip applier with preloaded Clip at the tip of the LAA. Ensure the loops at the ends of the Clip are pointed away from the LAA (See Figure 4).
- 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.
DEPLOYMENT WARNINGS
Carefully evaluate Clip position, tissue thickness, and tissue width prior to Clip deployment. To determine 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. - After the Clip is positioned correctly, grasp the Activation Lever and depress the Lever Release Button.
Slowly release the Activation Lever, allowing the Clip to close. - Deploy the Clip by slowly pulling the Deployment Tab at the proximal end of the Handle.
NOTE: The Deployment Tab with steel cables may be completely removed from the end of the Handle (See Figure 6). CAUTION: Take care to minimize manipulation of the LAA and Clip after Clip deployment. - Following Clip deployment carefully squeeze the Activation Lever to retract the Clip Pull Bar against the Deployment Loop of the Clip applier to prevent unintentional tissue snags when removing the Deployment Loop.
- Carefully remove the Deployment Loop from the LAA leaving the Clip and attachment suture behind (See Figure 7).
NOTE: After pulling the Deployment Tab, the AtriClip LAA Exclusion System cannot be used to reposition or remove the Clip.
