The UroLift System is indicated for the treatment of symptoms due to urinary outflow obstruction secondary to benign prostatic hyperplasia (BPH), including lateral and median lobe hyperplasia, in men 45 years of age or older.
The UroLift 2 ATC Advanced Tissue Control System is a modification of the UroLift 2 System (last cleared in K201837). The primary difference is the addition of a wing component on the distal tip of the UroLift 2 ATC Advanced Tissue Control System which provides a larger footprint. This design feature is intended to provide better mobilization of tissue when performing the UroLift System procedure.
The UroLift System (both the UroLift 2 and UroLift 2 ATC) is designed to access the prostatic urethra and deliver one UroLift Implant through a lobe of the prostate. The UroLift 2 System is inserted into the urethra through the penile orifice and used to displace the urethra toward the prostatic capsule. The UroLift Implant is then deployed transversely through the prostatic tissue. Multiple implants are deployed in the UroLift 2 System procedure. The implants secure the retracted position of the urethra, thereby maintaining an expanded urethral lumen, reducing fluid obstruction and improving lower urinary tract symptoms (LUTS). This is accomplished by holding the approximated position of the inner (urethral) tissue and the outer (capsular) tissue of the prostate with the UroLift Implant. The procedure typically requires 2-6 implants to retract the obstruction. The UroLift 2 ATC Advanced Tissue Control System consists of two main components, the UL2 Delivery Handle and the UroLift 2 ATC Implant Cartridge (single use). Each UroLift 2 ATC Implant Cartridge comes pre-loaded with one UroLift Implant. The Delivery Handle with the Implant Cartridge installed is known as the Delivery Device.
This document is a 510(k) summary for a medical device called the UroLift 2 ATC Advanced Tissue Control System. It describes the device's design, intended use, and how it compares to a predicate device and a reference device. It also outlines the performance and biocompatibility testing conducted to demonstrate substantial equivalence.
However, the provided text does not contain information about acceptance criteria and the study that proves the device meets those criteria in the context of an AI/ML medical device submission. This document is for a mechanical medical device, specifically an "Implantable Transprostatic Tissue Retractor System," which treats benign prostatic hyperplasia (BPH). The information requested in your prompt (acceptance criteria, sample sizes for test/training sets, expert ground truth, MRMC studies, standalone performance, etc.) are all highly relevant to the evaluation of AI/ML-driven medical devices.
Since the provided text does not describe an AI/ML device or its performance study, I cannot extract the requested information. The document focuses on demonstrating substantial equivalence to a predicate mechanical device through mechanical performance testing, biocompatibility testing, sterilization, and shelf-life testing, not on AI/ML model performance.
Therefore, I cannot populate the table or answer the specific questions about AI/ML device approval from this document.
§ 876.5530 Implantable transprostatic tissue retractor system.
(a)
Identification. An implantable transprostatic tissue retractor system is a prescription use device that consists of a delivery device and implant. The delivery device is inserted transurethrally and deploys the implant through the prostate. It is designed to increase prostatic urethral patency by providing prostate lobe tissue retraction while preserving the potential for future prostate procedures and is intended for the treatment of symptoms due to urinary outflow obstruction secondary to benign prostatic hyperplasia in men.(b)
Classification. Class II (special controls). The special controls for this device are:(1) The elements of the device that may contact the patient must be demonstrated to be biocompatible.
(2) Performance data must demonstrate the sterility of the patient-contacting components of the device.
(3) Performance data must support shelf life by demonstrating continued sterility of the device (of the patient-contacting components), package integrity, and device functionality over the requested shelf life.
(4) Non-clinical testing data must demonstrate that the device performs as intended under anticipated conditions of use. The following performance characteristics must be tested:
(i) Deployment testing must be conducted.
(ii) Mechanical strength must be conducted.
(iii) Resistance-to-degradation testing must be conducted.
(5) Non-clinical testing must evaluate the compatibility of the device in a magnetic resonance environment.
(6) In vivo testing must demonstrate safe and effective use, assess the impact of the implants on the ability to perform subsequent treatments, document the adverse event profile associated with clinical use, and demonstrate that the device performs as intended under anticipated conditions of use. The following performance characteristics must be tested:
(i) Deployment testing must be conducted.
(ii) Implant migration must be conducted.
(7) Labeling must bear all information required for safe and effective use of the device, and must include:
(i) Specific instructions, warnings, cautions, limitations, and the clinical training needed for the safe use of the device.
(ii) Information on the patient population for which the device has been demonstrated to be effective.
(iii) A detailed summary of the device technical parameters.
(iv) Information on how the device operates and the typical course of treatment.
(v) An expiration date/shelf life.
(vi) A detailed summary of the device- and procedure-related complications or adverse events pertinent to use of the device.
