Indications for Use
The VersaD Delivery Catheter is intended for use with compatible guide catheters in facilitating the insertion and guidance of catheters into selected blood vessels in the neuro and peripheral vascular systems.
Device Story
VersaD Delivery Catheter is a single-lumen, variable stiffness catheter; features long, tapered tip with radiopaque markers; proximal luer hub; distal hydrophilic coating. Used in neuro and peripheral vascular systems to facilitate insertion/guidance of other catheters. Operated by clinicians in clinical settings. Device tracks through vasculature; hydrophilic coating reduces friction; radiopaque markers allow visualization under fluoroscopy. Benefits include improved access to target vessels during vascular procedures. Device is single-use, sterile, and EO-sterilized.
Clinical Evidence
Bench testing only. No clinical data. Performance evaluated via design verification (surface integrity, coating uniformity, device compatibility, push/track, torque response, particulate, kink resistance, burst strength, tensile strength, radiopacity, delivery/retrieval force) and biocompatibility (ISO 10993-1, cytotoxicity, irritation, sensitization, systemic toxicity, pyrogenicity, complement activation, thrombogenicity, hemolysis).
Technological Characteristics
Single-lumen catheter; shaft: stainless steel and Pebax; luer: Pebax; markers: Pebax/20% BaSO4. Hydrophilic coating. EO sterilization. Dimensions: 0.019" ID; 0.062" proximal OD; 0.082" distal OD; 140cm length. No software or electronic components.
Indications for Use
Indicated for use with compatible guide catheters to facilitate insertion and guidance of catheters into selected blood vessels in the neuro and peripheral vascular systems.
Regulatory Classification

Dear Prithul Bom:
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 (the 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" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).
Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30. Design controls; 21 CFR 820.90. Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).
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 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 Part 803) for devices or postmarketing safety reporting (21 CFR Part 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 Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-device-advicecomprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

#### Sterilization and Shelf Life
The VersaD™ Delivery Catheter is labeled as a single-use sterile device with a shelf life of 12 months. The sterilization process has been validated, and process monitoring controls are in place to ensure the device is EO sterilized to achieve a minimum sterility assurance level (SAL) of 10 °. Shelf-life studies have demonstrated that the product and packaging remain functional and sterile for 12 months.
#### Conclusions
The VersaD™ Delivery Catheter has the same intended use and similar technological characteristics and principles of operation as the currently marketed predicate Delivery Catheter from the Route 92 Medical 088 Access System. Any differences between the subject and predicate devices do not raise new questions of safety and effectiveness. The subject device was evaluated through design verification, biocompatibility, and sterility testing. Based on the information submitted in this 510(k) submission, the VersaD™ Delivery Catheter is substantially equivalent to the currently marketed Delivery Catheter from the Route 92 Medical 088 Access System.
