Intended Use

Sterilization Wraps is intended to be used to enclose another medical device that is to be sterilized by a health care provider using: • Pre-vacuum steam at 270°F/132°C for 4 minutes Types of medical devices to be sterilized in the pre-vacuum cycle: General purpose reusable metal and nonmetal devices(No lumen) including devices with stainless steel diffusion-restricted spaces such as forceps and scissors, as well as other general medical instruments having mated surfaces, knurled areas etc. The size of the Devices to be sterilized shall allow Sterilization Wraps pack and form a closed space. Validated for dry time is 30 minutes for Sterilization Wraps. Color of wrap: Blue Size of wrap: 48 in x 48 in The maximum validated weight of load for Sterilization Wraps is 12kg. The wrap is intended to allow sterilization of the enclosed medical device(s) and also to maintain sterility of the enclosed device(s) until used.

Device Story

Sterilization Wraps are 63gsm, 3-layer (SMS) non-woven polypropylene sheets used by healthcare providers to wrap medical instruments for steam sterilization. The wrap acts as a microbial barrier, allowing sterilant penetration while maintaining sterility of the enclosed devices for up to 90 days post-sterilization. Used in clinical settings, the wrap is applied via sequential wrapping technique to form a closed space around instruments. It protects against tears and cuts during handling. The device is disposable and single-use. Benefits include maintaining instrument sterility until point-of-use, ensuring patient safety during subsequent medical procedures.

Clinical Evidence

No clinical data. Bench testing only. Performance verified via ISO 10993 (cytotoxicity, irritation, sensitization), ANSI AAMI ISO 17665-1 (steam sterilization validation, sterilant penetration, dry time), and ASTM standards for physical properties (tearing strength, breaking strength, air permeability, bursting strength, bacterial filtration efficiency). Testing confirmed 90-day sterility maintenance and effective barrier performance.

Technological Characteristics

3-layer (SMS: spunbond-meltblown-spunbond) non-woven polypropylene fabric; 63gsm; blue pigment. Dimensions: 48 in x 48 in. Sterilization method: Pre-vacuum steam (132°C). Standards: ISO 11607, ISO 10993-5/10, ASTM D5587, D5034, D737, D3776, D3786, F2101. Single-use, disposable.

Indications for Use

Indicated for healthcare providers to enclose general-purpose reusable metal and non-metal medical devices (no lumen) for sterilization via pre-vacuum steam (270°F/132°C for 4 minutes). Includes devices with stainless steel diffusion-restricted spaces (e.g., forceps, scissors, mated surfaces, knurled areas). Maximum load weight 12kg.

Regulatory Classification

Identification

Dear Ray Wang:

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. The 510(k) Premarket Notification Database located 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.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal

{1}------------------------------------------------

statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
