Intended Use

The TeesuVac Breast Biopsy Device Mark 1 is indicated to obtain percutaneous core biopsy specimens from soft tissue, and tumors of the breast. This product is intended for diagnostic use only, NOT therapy. The instrument is intended to provide breast tissue for histologic examination with partial or complete removal of the imaged abnormality.

The extent of histologic abnormality cannot be reliably determined from its mammographic appearance. Therefore, the extent of removing the imaged evidence of an abnormality does not predict the extent of removal of a histologic abnormality (e.g., malignancy). When the sampled abnormality is not histologically benign, it is essential that the tissue margins be examined for completeness of removal using standard surgical procedures.

Device Description

TeesuVac Breast Biopsy Device Mark 1 is a sterile, tetherless vacuum-assisted handheld biopsy device intended to obtain percutaneous core biopsy specimens from soft tissue and tumors of the breast with ultrasound guidance. TeesuVac Breast Biopsy Device Mark 1 is intended for biopsy and diagnosis only. The device is battery-driven and for single-patient use. An unsterilized Battery Pack that comes with the biopsy device is applied using the sterile Battery Clip, stored in the tray containing the biopsy device. The device is fitted with a 14G needle set to obtain specimens from soft tissue and tumors. The device is for professional users only. The tissue harvested by TeesuVac Breast Biopsy Device Mark 1 is intended for diagnostic use only.

The cannula needle consists of two hollow cannulas, an inner cannula with a specimen chamber, and a sharp outer cutting cannula that extends at high speeds over the aperture to acquire targeted tissue specimens. During the shot, a vacuum pulls the tissue into the chamber, followed by moving the outer cutting cannula forward over the specimen chamber to cut the tissue and collect the specimen in the specimen chamber. The TeesuVac Breast Biopsy Device Mark 1 has two buttons: the Slider for loading and the Sampling button to perform the biopsy procedure.

AI/ML Overview

The information provided describes a medical device, the TeesuVac Breast Biopsy Device Mark 1, and its substantial equivalence to a predicate device (Bard Max-Core Disposable Core Biopsy Instrument) based on non-clinical testing. It does not contain information about clinical studies with human participants, AI performance, or ground truth established by experts.

Therefore, many of the requested sections about acceptance criteria, efficacy studies, and ground truth cannot be filled from the provided text.

Here's the available information based on the document:

1. A table of acceptance criteria and the reported device performance

The document presents a comparison of attributes between the subject device (TeesuVac Breast Biopsy Device Mark 1) and the predicate device (Bard Max-Core, K133948). The "Evaluation" column in the table suggests that the subject device's performance is considered "Similar" or "Same as" the predicate device for most attributes, indicating that meeting these comparable performance characteristics serves as the de facto acceptance criteria for "substantial equivalence."

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

The document mentions "in-vitro device performance," "electrical & product safety," "sterilization," "biocompatibility," "predicate device comparison," and "simulated use testing." The specific sample sizes for these non-clinical tests are not provided. The data provenance is also not specified (country of origin, retrospective/prospective). The sample weight, length, and number of segments are reported for "Pig breast," indicating animal tissue was used for some performance testing.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

Not applicable. The document discusses device performance and comparison to a predicate, not diagnostic accuracy based on expert interpretation. No ground truth established by experts is mentioned.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. This is not a study involving human interpretation or adjudication.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

Not applicable. This document describes a medical device for obtaining biopsy specimens, not an AI-assisted diagnostic tool.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This is a physical medical device, not a software algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

For the performance metrics like sample weight, length, number of segments, and quality score, the "ground truth" would be the objective measurements obtained from the biopsy samples taken from "Pig breast." This is a form of objective measurement/laboratory data from a biological model, not expert consensus or pathology on human samples in the context of diagnostic accuracy.

8. The sample size for the training set

Not applicable. This is a physical device, and the testing described is non-clinical performance evaluation, not machine learning model training.

9. How the ground truth for the training set was established

Not applicable. (See #8).

Similarities between the TeesuVac Breast Biopsy Device Mark 1 and the predicate device(s):

  • Same Device type, Regulation number, and Product code *

  • Similar Patient population *
  • Similar fundamental scientific technology *
    • Similar operating principle
  • Single-use device *
  • The same number of samples per incision *
  • Similar needle material, design, and gauge *
  • Similar weight mass of the sample size *

The only directly patient contacting material is the needle, and all the needles are made of Stainless steel AISI 304, which is the same material.

Differences between the TeesuVac Breast Biopsy Device Mark 1 and the predicate device:

The mechanical principle of the Bard Max-Core is a self-contained handheld mechanical spring-loaded biopsy device. The TeesuVac Breast Biopsy Device Mark 1 is a self-contained handheld electromechanical spring-loaded vacuum-assisted biopsy device energized by a

{9}------------------------------------------------

motor powered by low voltage batteries (power supply). However, both the TeesuVac Breast Biopsy Device Mark 1 and the Bard Max-Core are essentially performing the sample harvesting utilizing springs that have been compressed. Whether the springs have been compressed by manual force or electromechanically driven force is insignificant. It is still similar regarding the sample, and thus no difference concerning safety and effectiveness.

The mechanism of action and mode of action of the TeesuVac Breast Biopsy Device Mark 1 is that the outer tube retracts to open the tissue chamber and subsequently moves forward to harvest the sample. The Bard Max-Core has a piercing shot where the inner core moves forward to open the tissue chamber, and the outer tube subsequently moves forward to harvest the sample. However, the TeesuVac Breast Biopsy Device Mark 1 is additionally vacuum-assisted. The Bard Max-Core and TeesuVac Breast Biopsy Device Mark 1 have fast-moving outer tubes that harvest the sample. The Bard Max-Core and TeesuVac Breast Biopsy Device Mark 1 are therefore comparable in their cutting method. The tissue samples' weight is comparable to that of the predicate device. There are no differences concerning vacuum-assisted and core needle devices reqarding safety and effectiveness.

Testing Summary:

The TeesuVac Breast Biopsy Device Mark 1 was evaluated in the following non-clinical studies: in-vitro device performance, electrical & product safety (IEC 60601-1, 60601-1-2), sterilization, biocompatibility, predicate device comparison, and simulated use testing.

Conclusion

The proposed TeesuVac Breast Biopsy Device Mark 1 (K212079) is substantially equivalent to the predicate device Bard Max-Core Disposable Core Biopsy Instrument (K133948).

The differences between the proposed and predicate devices do not impact the safety and effectiveness of the proposed device. Performance testing supports that the proposed device is substantially equivalent to the legally marketed predicate device.
