The device consists of a dilator tube with a central lumen for a 0.038-inch guidewire and a proximal handle. The tube surface features a friction-reducing coating; the device is radiopaque for fluoroscopic monitoring. A built-in hemostasis valve prevents blood leakage during operation. Used in clinical settings by physicians during percutaneous catheterization procedures, the device facilitates the insertion of intravascular instruments. By expanding the access site, it enables safer and easier delivery of therapeutic or diagnostic catheters, potentially reducing trauma to the vessel wall. ## Clinical Evidence Bench testing only. Performance validation included primary dimension, exterior surface condition, liquid leakage, bending, solvent resistance, coating thickness, simulation, connection strength, X-ray visibility, and conical fitting tests. Biocompatibility testing included cytotoxicity, sensitization, intracutaneous reactivity, acute systemic toxicity, hemolysis, thrombosis, coagulation, and pyrogen tests. Sterilization validation and package integrity were also verified. ## Technological Characteristics Device consists of a dilator tube and proximal handle. Features a central lumen for 0.038-inch guidewire and a hemostasis valve. Surface includes a friction-reducing coating. Radiopaque for fluoroscopic visualization. Sterilization method not specified. No software or electronic components. ## Regulatory Identification A vessel dilator for percutaneous catheterization is a device which is placed over the guide wire to enlarge the opening in the vessel, and which is then removed before sliding the catheter over the guide wire. ## Predicate Devices - RetroFlex™ Dilator Kit ([K093554](/device/K093554.md)) - Estech Percutaneous Dilator Insertion Kit ([K070749](/device/K070749.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

R. China Tel: 86-755-86026416 Fax: 86-755-86026251 Email address: shixiaoli@lifetechmed.com Date of Submission: 5 Dec 2012 Proposed Device: LawMax™ Dilator Classification: Class II, DRE, 21 CFR 870.1310 Dilator, Vessel, For Percutaneous Catheterization Predicate Device: Edwards Lifesciences, LLC - RetroFlex™ Dilator Kit cleared under K093554 a) - Estech Estech Percutaneous Dilator Insertion Kit cleared under K070749 b) Intended Use: LawMax™ Dilator is is intended for use in the dilation of the peripheral vasculature. Device Description: LawMax™ dilator is intended to dilate the puncture tunnel of the skin, subcutaneous tissue and vascular wall. The device is compised of a dilator tube and a handle connected to its proximal end. There is a lumen in the tube center from distal end to proximal end which can accept a 0.038 inch guide wire. The tube surface is coatings which can reduce the friction during the insertion manipulation. Operator can monitor the tube using fluoroscope guidance. A handle groximal end of the tube is available to facilitate operation. There is a hemostasis valve which can be adjusted to prevent blood leaking. The specification of LawMax™ dilator is definite by the outer diameter of the cylindrical part of the tube. Comparison with Predicate device: The LawMax™ Dilator is substantially equivalent to the predicate devices in intended use, design, specifications, packaging, and sterlization. For each predicate device there are slight variations, yet do not fundamentally change the scientific technology of the devices, which is to dilate vessels for intravascular devices. A summary of equivalency is in Section 6. {1}------------------------------------------------ Premarket Notification Section 510(k) Submission LawMax™ Dilator Section III 510(K) Summary Ref No.: LT/TS/18FDA-01 Testing Conclusion: Performance testing was conducted to validate and verify that the proposed device met all design specifications and was substantially equivalent to the predicate device, including: - .
