Intended Use

The KARL STORZ Cholangiography Set consists of manually operated reusable surgical devices intended for use by qualified surgeons in minimally invasive intraoperative cholangiography in adults and pediatric patients ≥ 13 years of age.

Device Story

The KARL STORZ Cholangiography Set is a collection of manually operated, reusable surgical instruments used during endoscopic surgery to facilitate intraoperative cholangiograms. The set includes a Cholangiography Fixation Clamp, a Guide Tube for Cholangiocatheter, and a BERCI Plastic Stylet. During minimally invasive procedures, the Guide Tube provides a pathway for catheter insertion; the Fixation Clamp secures the catheter to prevent movement; and the BERCI Plastic Stylet, which is radiolucent, replaces the metal trocar sheath to eliminate metal shadows during X-ray imaging of the biliary system. These components work together to ensure precise catheter placement and clear visualization of the bile ducts. The device is used by qualified surgeons in an operating room setting. By maintaining optimal positioning and reducing imaging interference, the device assists the surgeon in obtaining clear diagnostic images of the biliary anatomy, thereby supporting clinical decision-making during surgery.

Clinical Evidence

No new clinical trials were conducted. Safety and effectiveness were supported by published literature regarding the use of the KARL STORZ Cholangiography Set in the specified patient population. Bench testing included functionality (interlocking, load force, grasping), biocompatibility (ISO 10993 series), and reprocessing validation (ISO 11737, ISO 17665, ISO 17664).

Technological Characteristics

Manually operated, reusable surgical instruments. Materials comply with ISO 7153-1 (metallic materials). Components include a BERCI Plastic Stylet (10.5 mm OD), Guide Tube (4.8 mm OD), and Fixation Clamp. Connection techniques utilize welding and thread gluing. Sterilization via steam (pre-vacuum). No software or electronic components.

Indications for Use

Indicated for minimally invasive intraoperative cholangiography in adults and pediatric patients ≥ 13 years of age.

Dear Jordan Verla:

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.
