Device Facts

• Record ID: K053644
• Device Name: THROMBIGEL THROMBIN/GELATIN FOAM HEMOSTAT
• Applicant: Vascular Solutions, Inc.
• Product Code: QSX · SU
• Decision Date: Feb 9, 2006
• Decision: SESE
• Submission Type: Traditional
• Device Class: Class U
• Attributes: Therapeutic

Intended Use

The ThrombiGel thrombin/gelatin foam hemostat is applied topically and is indicated as a trauma dressing for temporary control of moderate to severely bleeding wounds and for the control of surface bleeding from vascular access sites and percularedus and or tubes.

Device Story

ThrombiGel is a topical hemostatic dressing consisting of a lyophilized gelatin foam pad containing thrombin, sodium carboxymethylcellulose, and calcium chloride. Applied directly to bleeding sites, the device acts as a physical barrier to blood flow when used with manual compression. Thrombin facilitates hemostasis by enzymatically converting fibrinogen to fibrin, accelerating the natural clotting cascade. The device is intended for use in clinical settings for trauma management and vascular access site control. It provides a localized environment that promotes clot formation, assisting healthcare providers in achieving hemostasis and reducing bleeding complications.

Clinical Evidence

Bench testing only. Non-clinical testing assessed the physical properties of the lyophilized pad and its efficacy in achieving hemostasis. Results confirmed the device's suitability for its intended use.

Technological Characteristics

Lyophilized gelatin foam pad containing thrombin, sodium carboxymethylcellulose, and calcium chloride. Functions as a topical physical barrier and enzymatic clotting agent. No performance standards developed under section 514.

Indications for Use

Indicated for patients requiring temporary control of moderate to severe bleeding wounds, or surface bleeding from vascular access sites and percutaneous catheters or tubes.

Regulatory Classification

Identification

To temporarily control bleeding and cover external wounds.

Dear Ms. Busklein:

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. 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 (PMA), 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 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
