Intended Use
The Origin Cardiac Stabilizer Occluder is indicated for use in cardiac surgery performed on the beating heart where local stabilization is required and a vessel may be temporarily occluded.
Device Story
Single-use sterile device consisting of stabilizer foot and occluders; used in cardiac surgery on beating heart. Stabilizer foot attaches to Origin Cardiac Stabilizer Clamp, which mounts to self-retaining rib/sternal retractor or stationary platform; alternatively, foot can be sutured directly to heart epicardium. Forceps position occluder over target vessel; occluder advanced and locked to provide temporary vessel occlusion. Device removed upon procedure completion. Used by surgeons in clinical setting to facilitate surgical access and vessel management.
Clinical Evidence
No clinical data provided; device relies on mechanical design and substantial equivalence to existing predicate devices.
Technological Characteristics
Mechanical vascular clamp; single-use; sterile. Comprises stabilizer foot and occluder mechanism. Attaches to surgical retractors or sutured to epicardium. No electronic, software, or energy-based components.
Indications for Use
Indicated for patients undergoing cardiac surgery on a beating heart requiring local stabilization and temporary vessel occlusion.
Regulatory Classification
Identification
A vascular clamp is a surgical instrument used to occlude a blood vessel temporarily.

## 21 CFR §807.92 a(2)
**Trade name:** To Be Determined
**Common name:** Clamp
**Classification name:** Vascular Clamp §870.4450
## 21 CFR §807.92 a(3)
**Identification of predicate(s):** Substantial equivalence for the Origin Cardiac Stabilizer Occluder is based on its similarities to the predicate device: the CardioThoracic System’s (CTS) Stabilizer and Pilling’s Micro Anastomosis Clamp. It shares the technological characteristics as the predicate devices. The Origin Cardiac Stabilizer Occluder is also similar in intended use.
## 21 CFR §807.92 a(4)
**Device Description-parts and function/concept:** This Origin Cardiac Stabilizer Occluder is a single use sterile device. It consists of a stabilizer foot, and occluders. The Origin Cardiac Stabilizer Occluder may be used by attaching the stabilizer foot to the Origin Cardiac Stabilizer Clamp; then this assembly is attached to a self retaining rib retractor or sternal retractor or other stationary platform. The Origin Cardiac Stabilizer Occluder may also be used by suturing the stabilizer foot to the desired area of the heart. The stabilizer foot rests against the epicardium. Forceps may be used to position

Dear Ms. Royster:
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 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 Good Manufacturing Practice for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic GMP 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.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for *in vitro* diagnostic devices), please contact the Office of Compliance at (301) 594-4648. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). Other general information on your responsibilities under the Act may be obtained from the Division of Small Manufacturers Assistance at its toll-free number (800) 638-2041 or at (301) 443-6597.
