The device description details a set of physical tools (wire guides, catheters, needles) used for a manual procedure. There is no mention of software, algorithms, image processing, or any terms related to AI or ML. The performance studies focus on material properties and physical integrity.
No.
This device is designed to create percutaneous access to the kidney. It is an access tool rather than a device intended to treat a condition or disease.
No
This device is used for gaining percutaneous access to the kidney through controlled fine wire puncture for therapeutic or interventional purposes, not for diagnosing a condition.
No
The device description explicitly lists multiple physical components made of materials like stainless steel, nylon, and TFE tubing, and describes their physical dimensions and functions. This is a hardware device, not software only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to gain percutaneous access to the kidney for a medical procedure. This involves physically interacting with the patient's body.
- Device Description: The device is a set of instruments (wire guides, catheter, needles) used for a surgical/interventional procedure. It is designed to be inserted into the body.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
IVD devices are used in vitro (outside the body) to analyze samples. This device is used in vivo (inside the body) for a procedural purpose.

Device Description
The Lawson Retrograde Nephrostomy Wire Puncture Set is used to gain percutaneous access to the kidney by means of a controlled fine wire puncture from within the collecting system.
The Lawson Retrograde Nephrostomy Wire Puncture Set is composed of the tipdeflecting wire guide, catheter, sheathed puncture wire, coaxial needle assembly (inner and outer needle cannulae) and working wire guide. The tip-deflecting wire guide is used to direct the catheter into the desired calyx in a retrograde manner using standard access techniques, followed by exchange of the deflecting wire with the sheathed puncture wire. To initiate percutaneous nephrostomy access, the puncture wire is unsheathed and advanced from the catheter through the kidney towards the patient's flank and through the skin. The coaxial needle assembly is then advanced over the puncture wire and into the renal collecting system, and then the puncture wire and inner needle cannula are removed to allow a working wire guide to be placed through the outer needle cannula.
- . The tip-deflecting wire guide has a three-ring handle which twist-locks with the catheter. The tip-deflecting wire guide is made from stainless steel and is available in an outer diameter of 0.045 in.
- . The catheter is available in an outer diameter of 7 Fr with a length of 82.5 cm and made of braided nylon tubing. The sheathed puncture wire can interlock with the proximal portion of the catheter.
- The sheath is made of radiopaque TFE tubing which extends 1 cm from the . catheter when locked together. The sheath is available in an outer diameter of 3 Fr with a length of 85 cm.
- . The puncture wire is made of stainless steel with a plastic pin vise handle. The puncture wire has an outer diameter of 0.43 mm with a length of 145 cm.
- . The needle set has a 22 gage inner needle that is 22.5 cm in length with the outer needle being 18 gage and 14 cm in length.
- . The working wire guide is made of stainless steel and is 0.97 mm in diameter and 145 cm in length.
The set will be supplied sterile and is intended for one-time use. The set is packaged in a peel-open pouch with a three-year shelf life.

Dear Minjin Choi:
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/cfpmp/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.
