Intended Use

Pajunks soft tissue biopsy, puncture and aspiration cannulas and needles listed above are intended for obtaining biopsies from soft tissues, for use in puncturing and for aspiration. They are not appropriate for bone biopsies. Pajunks soft tissue puncture and aspiration Kit acc. Steinhoff is intended for use in puncturing and aspiring for soft tissue biopsy. Pajunks breast localization cannulas/ needles can be used in Mammographic procedures to obtain breast lesion tissue. Pajunks Breast localization cannulas/ needles are intended for diagnostic sampling of breast tissue during breast biopsy procedures. They are to be used for diagnostic purposes only and are not intended for therapeutic uses. The Breast localization cannulas/ needles are indicated to provide breast tissue samples for diagnostic sampling of breast abnormalities. It is designed 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 removal of 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. This device is not indicated for use under MR based imaging technologies, such as MRI.

#### Special Sprotte tip cannula/ needle for aspiration, puncture and biopsy

Pajunks soft tissue biopsy, puncture and aspiration cannulas and needles listed above are intended for obtaining biopsies from soft tissues, for use in puncturing and for aspiration. They are EO-sterilized, latex-free devices for single use.

It is not appropriate for bone biopsies.

#### Device Description

### Soft Tissue Biopsy, Puncture and Aspiration Cannulas and Needles

The cannulas and needles consist of medical grade steel, plastic luer hub and stylet (stabilizing mandrin inside cannula). For safety reasons, the graduated puncture cannula also has an additional depthstop installed at the shaft of the cannula.

#### Aspiration puncture cannula type Chiba Special

The cannula Type Chiba Special has been developed by PAJUNK® with an approx. 1 cm matted finish of the cannula tip and three additional ring-markings.

#### Aspiration puncture cannula type Chiba with beveled tip

For safety reasons, the graduated puncture cannula/ needle has an additional depth-stop installed at the shaft. As a standard, the cannulas/ needles with beveled tip are normally equipped with a handle plate and a depth stop.

#### Initial puncture cannula

This universally usable puncture cannula/ needle made of high-grade stainless steel is suitable for all percutaneous punctures with guidance wires. It is available in a 2-parted and in a 3-parted version, with and without graduation. The outer cannula has a rounded, blunt tip, and it is designed to match the inside stylet-cannula.

#### Special puncture cannula with atraumatic Sprotte tip

This cannula with a Special Sprotte tip is intended for obtaining biopsies from soft tissues, for use in puncturing and for aspiration. It is an EO-sterilized, latex-free device for single use.

MEDIZINTECHNOLOGIE

#### Aspiration-puncture cannula with injecting tube acc. Steinhoff

The puncture kit according Dr. Steinhoff contains a Chiba-type puncture cannula/ needle with a cannula rider and a flexible tube. The millimeter-precise introduction of the puncture needle by means of the cannula rider is facilitated with the aid of the centimeter-graduation and the corresponding markings at intervals of 5 mm. Thereby, the needle can be quided safely, without lacking the necessary flexibility.

#### Breast Localization cannulas

Pajunks breast localization cannulas can be used in Mammographic procedures to obtain breast lesion tissue.

#### Predicate Devices:

Predicate Device for Pajunks soft tissue biopsy and aspiration cannulas and needles are the cannulas and needles cleared for market by Manan in K980211. These devices have identical indications for use and the same technical specification in materials and grinding as Pajunks cannulas.

Pajunks Chiba cannulas/ needles are already cleared for a different intended use (anesthesia conduction, spinal and epidural) in K040965.

The detailed discussion of substantial eqivalence can be found in Section 12 of this submission.

#### Sterilization

Pajunks soft tissue biopsy and aspiration cannulas and needles are supplied packed in a blister as single-use, sterile, pyrogenfree and latex free disposable cannulas.

The contract sterilizer and the sterilizing process at Sterigenics is the same as that one used for all further Pajunk products already cleared for market in the USA. All cannulas are very similar in dimensions and materials.

Sterilization of Pajunks soft tissue biopsy and aspiration cannulas and needles at Sterigenics is being done according to a documented process. This Ethylene Oxide sterilization process is recurrently evaluated for suitability and effectiveness and the results are acceptable.

Sterilization of the Pajunks soft tissue biopsy and aspiration cannulas and needles is accomplished using Ethylene Oxide (EO) sterilization to a Sterility Assurance Level (SAL) of < 10°. After manufacture the cannulas are arranged in a foil bag which is sealed. EO sterilization is accomplished with exposure to 100% EO in accordance with AAMI/ISO 10993-7.

#### Packaging and Labeling

The cannulas and needles subject to this premarket notification are packed and labeled employing the same validations, in-process-controls, procedures and materials as Pajunks disposable anesthesia conducting cannulas/ needles already cleared for market.

A process descriptions for labeling and packaging can be found in section 13.0 of this submission.

#### Biocompatibility status

All materials employed in the manufacturing process that may come in contact with blood, tissue or fluids to be injected have been cleared in Pajunks former 510(k) applications. Therefore they are deemed to be biocompatible. Testing according to ISO 10993 has been conducted successfully employing cannulas/ needles that consists of identical materials.

Furthermore these materials are long term proven materials for the use with medical devices.

Device Name:

Breast localization cannulas/ needles

Indications for Use:

Pajunks breast localization cannulas/ needles can be used in Mammographic procedures to obtain breast lesion tissue.

Pajunks Breast localization cannulas/ needles are intended for diagnostic sampling of breast tissue during breast biopsy procedures. They are to be used for diagnostic purposes only and are not intended for therapeutic uses.

The Breast localization cannulas/ needles are indicated to provide breast tissue samples for diagnostic sampling of breast abnormalities. It is designed 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 removal of the imaged evidence of an abnormality does not predict the extent of removal of a histologic abnormality (e.g., malignancy).
