Indications for Use
The PREVENT™ Kit is intended to be used as an alternative to foam and other negative pressure wound therapy dressings when used in conjunction with the CCT1 and CCT Mini Negative Pressure Wound Drainage Pumps (K082311) for the application of negative pressure wound therapy to the wound. When used in conjunction with the CCT1 or CCT Mini Negative Pressure Wound Drainage Pumps, the PREVENT™ Kit is indicated for patients who would benefit from a suction device, particularly as the device may promote wound healing by removal of excess exudate, infectious material and tissue debris. The PREVENT™ Kit is appropriate for use on the following wounds: Pressure Ulcers Diabetic/Neuropathic Ulcers Venous Insufficiency Ulcers Traumatic Wounds Post-Operative and Dehisced Surgical Wounds Skin Flaps and Grafts The system is for prescription use only.
Device Story
PREVENT™ Kit is a sterile, single-use dressing system for negative pressure wound therapy (NPWT). Components include a thermoplastic elastomer (TPE) wound contact barrier, adhesive film drapes, and a dome assembly with drainage tubing. Used with CCT1 or CCT Mini pumps; the pump creates a vacuum to remove exudate, infectious material, and tissue debris from the wound bed into a collection canister. Operated by healthcare professionals in clinical or home settings. The TPE barrier provides flow pathways for exudate removal. The system promotes wound healing by maintaining a closed, negative-pressure environment. Output is the physical removal of wound fluids; clinical decision-making is supported by visual monitoring of the wound bed through the transparent dressing and drape. Benefits include effective exudate management and wound healing support.
Clinical Evidence
No human clinical trials. Evidence includes bench testing (7-day simulated use, tensile strength, seal strength, alarm functionality), shelf-life testing (1-year real-time/accelerated), biocompatibility (ISO 10993-1), and a 35-day GLP animal study in swine comparing wound healing and histological response to a control. Usability testing (ISO 62366-1) with 15 participants showed 249/272 subtasks performed successfully with no serious use errors.
Technological Characteristics
Components: TPE (Medalist MD-10135) wound contact barrier, polyurethane film drape with acrylate adhesive. Principle: NPWT via vacuum pump. Dimensions: 20cm x 25cm barrier. Sterilization: Ethylene oxide (ISO 11135-1). Connectivity: Mechanical connection to external pump via Luer lock. Software: None (mechanical dressing kit).
Indications for Use
Indicated for adult patients requiring negative pressure wound therapy (NPWT) for pressure ulcers, diabetic/neuropathic ulcers, venous insufficiency ulcers, traumatic wounds, post-operative/dehisced surgical wounds, and skin flaps/grafts. Contraindications not specified.
Regulatory Classification
Identification
A powered suction pump is a portable, AC-powered or compressed air-powered device intended to be used to remove infectious materials from wounds or fluids from a patient's airway or respiratory support system. The device may be used during surgery in the operating room or at the patient's bedside. The device may include a microbial filter.

Dear Cynthia Pritchard:
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 (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. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"
