The Kalera Vacuum Aspiration Catheter (K-VAC™) is used to establish a conduit during endoscopic urological procedures for the treatment of urinary stones.
K-VAC is a sterile, single-use aspiration-irrigation catheter that is designed to assist in the removal of stone fragments during standard ureteroscopy. K-VAC is a dual-lumen catheter with two concentric lumens. The outer lumen is the irrigation lumen that accommodates delivery of irrigation/contrast solution. The larger, inner lumen is the aspiration lumen through which the stone fragments are removed. The inner diameter of the aspiration lumen is 2.5 mm. The distal 5 cm of the K-VAC tip is soft with a steering mechanism on the catheter handle and embedded wires to actuate the tip. In this way, stones and debris in the renal calyces can be fluidized with irrigation and aspirated.
An additional component to the device is a radiopaque introducer, which is 0.035" and 0.038" guidewire compatible. The tip of the introducer has a soft tapered tip.
The design of K-VAC allows the trained operator to maneuver and position K-VAC via a standard 12/14F ureteral access sheath under fluoroscopic guidance, followed by controlled irrigation and aspiration of stones and debris from the renal pelvis and calyces.
K-VAC is composed of well-characterized biocompatible materials commonly used in urinary catheters. The catheter is mechanical and contains no electrical components.
The provided text is a 510(k) summary for the Kalera Vacuum Aspiration Catheter (K-VAC), a medical device. It does not describe acceptance criteria or a study that proves the device meets those criteria in the context of an AI/ML medical device. Instead, it details the process for demonstrating substantial equivalence of a mechanical medical device to a predicate device, focusing on performance testing, biocompatibility, sterilization, and packaging/shelf life.
Therefore, I cannot extract the information required by your prompt, such as acceptance criteria for AI performance (like sensitivity, specificity), sample sizes for test sets in an AI context, expert ground truth establishment, MRMC studies, or training set details, because this document pertains to a physical, non-AI medical device.
The study described is a demonstration of equivalence to a predicate device (ClearPetra Suction-Evacuation Sheath, K161110) for a mechanical device, not the performance of an AI/ML algorithm.
Here's a breakdown of why this document doesn't fit your prompt's requirements for an AI/ML device:
- Device Type: The K-VAC is described as a "sterile, single-use aspiration-irrigation catheter" and "mechanical and contains no electrical components." This clearly indicates it's a physical medical device, not an AI/ML system.
- Performance Testing: The "Performance Testing" section outlines bench testing (dimensional conformance, flow, product cycling, tortuous path, actuation, torque, bond), animal studies (fluoroscopy, irrigation, aspiration in a porcine model), usability assessment, biocompatibility, sterilization, and packaging/shelf life. These are typical tests for mechanical medical devices, not AI/ML algorithms.
- "Acceptance Criteria" Context: The document refers to meeting "product specifications" and "design input requirements" related to the mechanical performance of the catheter. It does not mention any statistical thresholds for AI performance metrics (e.g., AUC, sensitivity, specificity).
- No AI/ML Specifics: There is no mention of algorithms, models, training data, test data, ground truth established by expert consensus for image interpretation, or any other elements common in AI/ML device validation.
In summary, the provided text is irrelevant to the prompt, as it concerns a mechanical medical device, not an AI/ML product.

4. DESCRIPTION OF THE DEVICE
K-VAC is a sterile, single-use aspiration-irrigation catheter that is designed to assist in the removal of stone fragments during standard ureteroscopy. K-VAC is a dual-lumen catheter with two concentric lumens. The outer lumen is the irrigation lumen that accommodates delivery of irrigation/contrast solution. The larger, inner lumen is the aspiration lumen through which the stone fragments are removed. The inner diameter of the aspiration lumen is 2.5 mm. The distal 5 cm of the K-VAC tip is soft with a steering mechanism on the catheter handle and embedded wires to actuate the tip. In this way, stones and debris in the renal calyces can be fluidized with irrigation and aspirated.
An additional component to the device is a radiopaque introducer, which is 0.035" and 0.038" guidewire compatible. The tip of the introducer has a soft tapered tip.
The design of K-VAC allows the trained operator to maneuver and position K-VAC via a standard 12/14F ureteral access sheath under fluoroscopic guidance, followed by controlled irrigation and aspiration of stones and debris from the renal pelvis and calyces.
K-VAC is composed of well-characterized biocompatible materials commonly used in urinary catheters. The catheter is mechanical and contains no electrical components.
ട. INTENDED USE
The intended use / indications for use for the Kalera Vacuum Aspiration Catheter (K-VAC) as follows:
The Kalera Vacuum Aspiration Catheter™ (K-VAC™) is used to establish a conduit during endoscopic urological procedures for the treatment of urinary stones.
INTENDED USE COMPARED TO THE PREDICATE 6.
The intended use of the Kalera Vacuum Aspiration Catheter (K-VAC) is the same as the predicate device. Both devices are used to establish a conduit for irrigation and aspiration of kidney stones during standard ureteroscopy, are composed of biocompatible materials, and are sterile single-use devices.
TECHNOLOGY CHARACTERISTICS COMPARED TO THE PREDICATE 7.
There are similarities and differences between the technological characteristics of K-VAC and the predicate device. The devices are similar in their use and purpose, as both devices are used to introduce irrigation to fluidize kidney stones and both devices remove stones using aspiration. A few features of the devices are different. Table 1 on the following page highlights the similarities and differences.

8. PERFORMANCE TESTING
The 510(k) submission provided performance data to establish the substantial equivalence of K-VAC (the subject device) to the predicate device. A summary of these performance tests is provided below.
Performance Test Bench (Laboratory Testing): Bench performance testing was performed to evaluate dimensional conformance, flow, product cycling, tortuous path testing, actuation testing, torque, and bond testing. Results of verification and validation testing confirm that the aspiration and irrigation and other device characteristics meet product specifications and the device meets design input requirements.
Performance Testing Animal: Testing with K-VAC and the predicate device in a GLP Animal Study evaluated device performance under fluoroscopy, irrigation and aspiration using a porcine model. Equivalent pathology and histopathology findings were observed between K-VAC and the predicate device; some observations in both groups were a result of the difficulty in establishing access in a tortuous porcine renal model and were not attributed to either device. Average overall fluoroscopy time and procedure time were substantially equivalent between K-VAC and the predicate device.
Usability Assessment: A usability assessment was conducted as a part of the GLP Animal Study, and confirmed that all participants were successful in all tasks during use of K-VAC.
Biocompatibility Data: Biocompatibility testing was conducted for K-VAC as an external communicating device, tissue/bone/dentin contacting, limited duration exposure. Cytotoxicity (MEM Elution Method), Sensitization (Guinea Pig Maximization Test, Magnusson-Kligman Method), Irritation (Intracutaneous test), Acute Systemic Toxicity, Material Mediated Pyrogen Test (LAL Test) testing all resulted in passing test results. This leads to the conclusion that K-VAC is biocompatible and meets the requirements of ISO 10993-1.
Sterilization: Sterilization validation studies using ethylene oxide (EtO) confirmed sterilization to a sterility assurance level (SAL) of 106. The sterilization process was validated in accordance with ANSI AAMI ISO 11135: 2014, Over-Kill Approach.
Packaging and Shelf Life: Packaging validation testing, including transportation and distribution testing demonstrates the soundness of the product packaging to protect the device and maintain product sterility, integrity and functionality and supports a 12-month shelf life for K-VAC.
9. CONCLUSIONS
This 510(k) submission demonstrates that K-VAC is substantially equivalent to the predicate device.
