No.
The document describes an electrosurgical system for tissue resection and coagulation, and does not mention any AI, DNN, or ML components or functions. The software testing mentioned is for general device software functions (IEC 62304) and not specifically for AI.
Yes
The device is intended for tissue resection, coagulation, and removal of bladder tumors, as well as delivering injectable materials into the urinary bladder wall, all of which are direct medical interventions aimed at treating a condition.
No
The device is described as an electrosurgical system for tissue resection, coagulation, and delivery of injectable materials. Its purpose is therapeutic (removing tissue, coagulating, injecting materials), not to diagnose a condition or disease.
No
The device description clearly outlines hardware components like the "Multi4 Pump," "Multi4 B instrument," "Footswitch," and "Simple4tainer." It details their physical functions such as administering energy,
fluid transport, tissue collection, and accessing the bladder through a cystoscope. Furthermore, the performance studies include extensive electrical safety,
integrity, and functional testing typical for electrosurgical hardware, not solely software. While software verification and validation are mentioned, they are part of a broader system that includes significant physical components.
No. The device is used for surgical procedures (tissue resection, coagulation, and delivery of injectable materials) and tissue collection for pathology, not for in vitro examination of specimens derived from the human body for diagnostic purposes.
N/A
Intended Use / Indications for Use
The Multi4 System is intended for use by trained urologists for endoscopically controlled tissue resection and coagulation, and removal of bladder tumors (TURBT) via suction channel under controlled flow conditions following resection using a monopolar resectoscope. The Multi4 System is also intended to deliver injectable materials into the urinary bladder wall during transurethral endoscopic procedures.

Device Description
The Multi4 System is an electrosurgical system used during urethral resection procedures of adult patients. The system, intended to remove and collect tissue from the bladder, includes a single-use electrosurgical instrument, known as the Multi4 B, as well as the reuseable Multi4 Pump. The Multi4 Pump administers energy from an external electrosurgical unit to the handheld Multi4 B instrument, which has electrosurgical functions and allows for fluid transport and tissue sample collection. The Multi4 B instrument accesses the bladder through the working channel of a commercially available cystoscope. The Multi4 System is a prescription device intended for use in professional healthcare facilities by healthcare professionals (HCPs).
The Multi4 System consists of the following components:
• Multi4 Pump (with Integrated Fluid Control)
o Footswitch
• Multi4 B
o Resectoscope & Needle
o Simple4tainer (For collection of gross resected tissue pieces for pathology)

Dear Erin Gontang:
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"
Page 2
(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 (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-reporting-combination-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-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-devices/medical-device-safety/medical-device-reporting-mdr-how-report-medical-device-problems.
