Intended Use

The biopsy-needle is intended for soft-tissue biopsy (such as breast, kidney, liver, prostate).

Device Story

Semi-automatic biopsy needle; sterile, single-use, spring-loaded system. Components include handle, stylet, trigger, and coring guide. Used by clinicians for percutaneous soft-tissue biopsy (breast, kidney, liver, prostate). Device operates by manual insertion followed by a spring-loaded trigger mechanism that advances the cannula over the stylet notch to excise tissue. Output is a cylindrical tissue sample for histological analysis. MR-compatible design allows for use under MRI guidance. Benefits include improved sample quality and integrity compared to predicate, with clear visibility under MRI without significant artifacts or heating.

Clinical Evidence

Bench testing only. Evaluated penetration capacity, spring-loaded shot mechanism, and sample quality/integrity in animal tissue and apples. Sample sizes were measured and compared against acceptance criteria (5mm and 10mm). MR-compatibility assessed at 1.5T and 3T, confirming visibility without artifacts or heating. Biocompatibility testing included cytotoxicity, sensitization, acute systemic toxicity, and pyrogenicity. Results showed the device met all acceptance criteria and performed effectively.

Technological Characteristics

Sterile, single-use, spring-loaded biopsy needle. Materials differ from predicate to enable MR-compatibility. Dimensions include 14G, 16G, and 18G gauges with 10mm and 20mm notch sizes. Operates via mechanical spring-loaded trigger. Sterilized using validated ethylene oxide (EO) process.

Indications for Use

Indicated for soft-tissue biopsy (e.g., breast, kidney, liver, prostate) to obtain diagnostic tissue samples for histological examination during percutaneous procedures.

The semiautomatic Biopsy needle– BM is a sterile, spring loaded, disule biopsy system. It consists of the
following maior components: handle stylet. tincer and coring nuide.

{4}------------------------------------------------

# Intended Use/Indications for Use

The biopsy-needle is intended for soft-tis sue biopsy (such as breast, kidney, liver, prostate).

# Indications for Use Comparison

The proposed devices are working equivalently to the predicate device. They are all intended to obtain diagnostic samples of tissue for histological examination during a percutaneaous biopsy procedure. They differ only in optical design aspects. In addition the proposed device is MR-compatible.

## Technological Comparison

The BM is identical or similar in technology, design and material to the predicate devices are sterile and for single-use. The only difference between the two devicesare the materials of the needles as well as optical design aspects. Based on the same intended use and the similarities in technology, design and materials the proposed devices are substantially equivale/ reference devices. Biocompatibility, MR-testing, sterility and packaging demonstrate the safety and effectiveness of the proposed device

# Non-Clinical and/or Clinical Tests Summary & Conclusions

The purpose of the tests is to evaluate:

1) the penetration of the needle

2) The shot of the needle

3) The quantity of the sample taken

4) The quality/integrity of the sample taken

5) MR tests for artificat

6) Heating and induction test

7) Biocompatibility

For the present report different Semiautomatic Biopsy Need. The 5 samples have been manufactured in 5 different lots. 14G, 16G and 18G biopsy needles were used. The lengths ranged from 100 mm. The testing was conducted after the validated EO sterilization of all devices. Therefore the tests were conducted on final devices

Description of the tests

1) For the stylet perforation capacity, a biopsy needle in three different tissues (animal tissue and apples) according to the IFU. It isthen visually tested to ensure that the style tip could easily and effortlessly penetrate the tissue without causing tears or lacerations to create a good enty path for the cannula. The need in different tissues to assess the penetration capacity of the stylet tip. 2) To test the shot of the needle the release mechanism of the biopsy device were triggered in the air as well as in the animal tissue. If the device works well, the cannula would cover the tip of the stylet that contains then otch completely. With this you can test if the spinq has enough power to push the cannula over the notch to cuttissue. This was conducted for the 10 mm and 20 mm notch.

3) Different tissue samples were taken with biopsy devices for the 10mm and 20 mm notch. After that the collected samples was measured with aruler. The length was written down and the results were analyzed.

4) The taken tissue samples in test 3 are observed under video microscope.

The samples were carefully observed to seeif they are cylindrical, intact and abundant. This was also done for 10 mm and 20 mm notch samples.

5&6) Furthermore MR-compatibility tests were conducted.

For the tests we used similar needles that use the biopsy devices and tested them under a 37 and 1.5T MRI-System. The needle is clearly visible under MR-quidance without any major attifacts. Furthermore no heating occured in any unit 7) Biocompatibility tests for Cytotoxicity, Sensitization, Acute Systemice Toxicity and Pyrogenicy were conducted.

1.Needle penetration capacity

For all tested biopsy devices the insertion was optimal and conducted effortles sty with no difficulties at all. The acceptance criteria were met. This demonstrates that the devices works for penetration and is safe.

2.Shot of the needle.

For all tested hions v device the not the not the case for hotch notch sizes (10 mm and 20 mm ) From this

#### 21 CFR 807.92(a)(6)

{5}------------------------------------------------

============================================================================================================================================================================= it can be concluded that the spring is strong enough. The acceptance criteria were met and the device works and is safe.

#### 3.Quantity of the collected samples

Each sample for the liver and apple equals the notch size. For muscle tissue taken with the 10 mm notch the average length is 6.72 mm and for 20 mm notch 11.77 mm. Every sample was larger than the acceptance criteria of 5 mm and 10 mm. Therefore the criteria is met. The average sample size over all tissues is 8.82mm for the 10 mm notch. The device is therefore is therefore effective to take proper samples.

4.Quality/integrity of the collected samples

All samples are cylindrical, intact and abundant. The acceptance criteria were met. Because of this the device is effective and safe.

Based on the performed tests the proposed device is as safe and as effective as the predicate device. Furthe more the average sample size of the collected tissue is larger for the proposed device. Proposed device: 10 mm notch: 8.82 mm samples, 20 mm notch: 17.22 mm samples

Predicate device: 10 mm notch 7 cm samples, 20 mm notch: 13 mm samples

5&6.

Based on the MR-tests the device is MR-compatible. The new any major artificats and is cleary visible especially compared to the needle with stainless steel. In addition no heating or cured during these tests.

7. Biocompatibility were proofen with the conducted tests.

Conclusion:

The Semi-automatic Biopsy-Needle functions as intended. The results drawn from the non-dinical tests as well as the literature presented in this 510(k) submission demonstrate the proposed device is as safe, effectiveand performs as well as the legally marketed predicate device. The proposed device has a similiar intended use and design characteristics. The M-compatbility were proven with MR tests and the different needlemateliality. Therefore the proposed device is substantially equivalent to the predicate device.
