Indications for Use
GEM™ BIOVER disposable microvascular clamps are instruments which are used for all microsurgical procedures. They are used to occlude vessels during anastomosis, which is necessary as a result of vessel damage or thrombosis.
Device Story
GEM™ Biover Microvascular Clamps are sterile, single-use, disposable instruments used in microsurgery, plastic surgery, and hand surgery. Available in single and double configurations, they are color-coded by vessel type: yellow for arteries (higher clamping force) and green for veins. Clamps are applied by surgeons or scrubbed personnel in a hospital setting to temporarily occlude blood vessels during anastomosis. The device functions mechanically to stop blood flow, facilitating vessel repair. No software or electronic components are involved.
Clinical Evidence
No clinical data provided. Substantial equivalence is supported by design identity, non-clinical performance testing, and a packaging summative human factors/usability study.
Technological Characteristics
Mechanical vascular clamps; single and double configurations. Materials: Not specified. Sterilization: Gamma radiation. Packaging: Double Tyvek pouches. No energy source, connectivity, or software.
Indications for Use
Indicated for patients undergoing microsurgical procedures requiring temporary occlusion of blood vessels (arteries or veins) during anastomosis due to vessel damage or thrombosis.
Regulatory Classification
Identification
A vascular clamp is a surgical instrument used to occlude a blood vessel temporarily.

Dear Julie Carlston:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and 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) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.

#### IV. Device Description
The GEM™ Biover Microvascular Clamps (Clamps) are arterial and venous clamps in both single and double clamp configurations, available in varying sizes. The clamps are sterile, disposable clamps for single use. The clamps are used in microsurgery, plastic surgery, and hand surgery for the temporary occlusion of blood vessels during an anastomosis.
The clamps are available for arteries and veins. The clamping force is higher for the arterial clamps than for the veinous clamps. The clamps are identified by a product reference code and by the color of the clamp. The clamps for veins are green, and the clamps for arteries are yellow.
{4}------------------------------------------------
The clamps are packaged individually in two Tyvek pouches (double pouched). The devices in the Tyvek pouches are gamma sterilized and are placed in cartons of 10. The clamps are used once and are disposed of after use.
#### V. Intended Use and Indications for Use
The Intended Use remains the same as the predicate device (K011208).
Indication for Use
GEM BIOVER disposable microvascular clamps are instruments which are used for all microsurgical procedures. They are used to occlude vessels during anastomosis, which is necessary as a result of vessel damage or thrombosis.
The wording of the Indication for Use was modified slightly from the predicate to improve the clarity of the statement while maintaining the same intended use and scope. The indications for use statements are the same in intended clinical use and therefore there is no substantial change to the indication for use of the microvascular clamps. The similarity in the indication for use statements supports substantial equivalence.
## VI. Comparison of Technological Characteristics with the Predicate Device
The device and primary packaging of the double pouch configuration (sterile packaging) remain unchanged and are identical to the predicate device. There are no engineering or performance changes to the device or its packaging. The only technology change is a minor modification to the sales unit carton (box of 10 individual pouches) which was made to ease removal of the packaged (pouched) clamps. There is no change in sterilization.
In addition to the minor change to the carton, updates were made to the Instruction Manual and package labeling to reflect the new tradename of the device.

#### VII. Performance Data
The label design change and the outer carton sales unit design change were assessed and validated in a Packaging Summative Human Factors/Usability Study. Historical complaint data were reviewed and indicate no use-related concerns, thus, there are no use-related risks or complaints that trigger a need for further Human Factors validation.
#### VIII. Conclusions
The GEM Biover microvascular clamps remain unchanged from the predicate device. Performance testing has been completed to evaluate safety and effectiveness of the subject device as it compares to its predicate. The conclusions drawn from the risk-benefit assessment and nonclinical tests demonstrate that the proposed device is as safe, as effective, and performs as well as or better than the legally marketed predicate device. The proposed device is substantially equivalent to the predicate device.
