Device Facts

• Record ID: K003446
• Device Name: SYMMETRY AORTIC CLIP SYSTEM
• Applicant: St. Jude Medical Cardiovascular Group, Inc.
• Product Code: NCA · General, Plastic Surgery
• Decision Date: May 21, 2001
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 878.4300
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The Aortic Connector System is intended to create the aortic anastomosis of aortic autologous vein grafts.

Device Story

Mechanical device facilitating aortic vein graft anastomosis; replaces sutures to create secure, patent, reproducible connections. Consists of self-expanding Nitinol implantable connector and delivery system. Used in surgical settings by clinicians. Unlike predicate devices requiring manual circumferential clip application, this system is a unitary device deploying all clipping elements simultaneously around the anastomosis circumference. Clips pinch vessel edges without penetrating vessel wall. Benefits include reduced procedural complexity and improved anastomosis consistency compared to traditional suturing.

Clinical Evidence

Mechanical, in vitro, and animal testing conducted. Results demonstrate performance equivalent to standard suture anastomoses.

Technological Characteristics

Nickel Titanium alloy (Nitinol) implantable connector; U-shaped with rounded ends. Unitary delivery system for simultaneous clip deployment. Mechanical, non-powered device.

Indications for Use

Indicated for patients undergoing aortic autologous vein graft procedures requiring aortic anastomosis.

Regulatory Classification

Identification

An implantable clip is a clip-like device intended to connect internal tissues to aid healing. It is not absorbable.

Predicate Devices

• U.S. Surgical AutoSuture Vascular Anastomosis Clip Cartridge and Applier (K970793)

# Aortic Connector System

Common/Classification Name: Implantable Clip and delivery system as classified under 21 CFR 878.4300 and 4800

#### A. Legally Marketed Predicate Devices

The Aortic Connector System is substantially equivalent to the U.S. Surgical AutoSuture Vascular Anastomosis Clip Cartridge and Applier (K970793).

#### B. Device Description

The Aortic Connector System is a mechanical device used to facilitate an aortic vein graft anastomosis. The connector replaces sutures to create a secure, patent, and reproducible anastomosis. The Symmetry Aortic Connector System consists of a self expanding implantable connector and delivery system.

#### C. Indications for Use

The Aortic Connector System is intended to create the aortic anastomosis of aortic autologous vein grafts.

#### D. Substantial Equivalence Summary

Both devices are intended to be used in creating vascular anastomoses. The St. Jude Medical Anastomotic Technology Group Mechanical Anastomosis Connector is made of a Nickel Titanium alloy (Nitinol) in a "U" shape with rounded ends. The U.S. Surgical clip is made of Titanium in a "C" shape with blunted ends. The ends of both clips pinch the edges of the vessels together without penetrating the vessel wall.

The primary difference between the devices is the delivery method. The U.S. Surgical applier fires the clips one at a time, and the applier must be manually moved circumferentially around the anastomosis site. The St. Jude Medical Anastomotic

K003446S1

Technology Group Mechanical Anastomosis Connector is a unitary device with all clipping elements being deployed simultaneously around the circumference.

## E. Technological Characteristics

See Device Description above.

### F. Testing

Mechanical, In Vitro, and animal, testing has been conducted which demonstrates that the performance of the Aortic Connector System is equivalent to standard suture anastomoses.

## G. Conclusion

St. Jude Medical has demonstrated through its comparison of performance with standard suture anastomoses that the Aortic Connector System is equivalent to the predicate device.

Dear Mr. Sheridan:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic OS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
