Intended Use
The Kalera Vacuum Aspiration Catheter (K-VAC™) is used to establish a conduit during endoscopic urological procedures for the treatment of urinary stones.
Device Description
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.
More Information

Not Found

No
The device description explicitly states that the catheter is mechanical and contains no electrical components. There is no mention of AI or ML in the intended use, device description, or performance studies.

Yes
The device is used for the treatment of urinary stones by assisting in the removal of stone fragments, which constitutes a therapeutic purpose.

No

The device is described as an aspiration-irrigation catheter used for the removal of stone fragments during urological procedures. Its function is to facilitate the physical removal of stones, not to diagnose a condition.

No

The device description clearly outlines a physical catheter with lumens, a steering mechanism, embedded wires, and an introducer. It also mentions being mechanical and containing no electrical components, further indicating it is a hardware device.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to "establish a conduit during endoscopic urological procedures for the treatment of urinary stones." This describes a surgical/interventional device used in vivo (within the body) to facilitate a procedure.
  • Device Description: The description details a physical catheter used for irrigation and aspiration of stone fragments from the urinary tract. It's a mechanical device used to manipulate and remove material from the body.
  • Lack of Diagnostic Function: There is no mention of the device being used to analyze samples (blood, urine, tissue, etc.) in vitro (outside the body) to provide diagnostic information about a patient's condition. IVDs are specifically designed for this purpose.
  • Performance Studies: The performance studies focus on the mechanical and functional aspects of the catheter (flow, cycling, tortuosity, actuation, etc.) and its performance during a procedure (fluoroscopy time, procedure time, usability). These are typical performance metrics for surgical/interventional devices, not IVDs.
  • Anatomical Site: The device is used within the urinary tract, which is an in vivo application.

In summary, the Kalera Vacuum Aspiration Catheter is a surgical/interventional device used to assist in the removal of urinary stones during a procedure. It does not perform any diagnostic testing on samples outside the body, which is the defining characteristic of an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

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.

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.
