Intended Use

PAJUNK®s soft tissue biopsy, puncture and aspiration cannulas and needles are intended for obtaining biopsies from soft tissues, for use in puncturing and for aspiration. They are not appropriate for bone biopsies.

Device Story

Chiba SONO cannulas/needles are single-use, sterile, non-pyrogenic instruments for soft tissue biopsy, puncture, and aspiration. Device consists of stainless steel tubing, polycarbonate hub, and optional polymeric NanoLine coating. Key feature is 'CornerStone' reflector pattern imprinted on cannula surface to enhance ultrasound visibility. Used by physicians in clinical settings to gain tissue access or aspirate fluids; may be used during fluoroscopy. Enhanced visibility aids physician in guiding needle placement via ultrasound, potentially improving procedural accuracy and patient outcomes. Device is manually operated; no electronic or software components.

Clinical Evidence

Bench testing only. Testing included bending stability, breaking resistance, and hub-to-needle-bondage strength. Biocompatibility testing performed per ISO 10993-1. Sterilization validated to ensure SAL of 10^-6.

Technological Characteristics

Materials: stainless steel tubing, polycarbonate hub, epoxy resin glue, optional polymeric NanoLine coating. Sensing principle: passive ultrasound reflection via 'CornerStone' reflector pattern. Single-use, sterile, EtO-sterilized. Dimensions/form factor: standard cannula/needle geometry. No electronic components or software.

Indications for Use

Indicated for soft tissue biopsy, puncture, and aspiration in patients requiring such procedures. Contraindicated for bone biopsies.

Regulatory Classification

Identification

A gastroenterology-urology biopsy instrument is a device used to remove, by cutting or aspiration, a specimen of tissue for microscopic examination. This generic type of device includes the biopsy punch, gastrointestinal mechanical biopsy instrument, suction biopsy instrument, gastro-urology biopsy needle and needle set, and nonelectric biopsy forceps. This section does not apply to biopsy instruments that have specialized uses in other medical specialty areas and that are covered by classification regulations in other parts of the device classification regulations.

# Indications for use

PAJUNK®s soft tissue biopsy, puncture and aspiration cannulas and needles are intended for obtaining biopsies from soft tissues, for use in puncturing and for aspiration.

They are not appropriate for bone biopsies.

# Device Description:

Chiba SONO cannulas/ needles enhanced for ultrasound visibility are single use sterile and nonpyrogenic devices used to gain entry or puncture the tissue and aspirate soft tissue for biopsy purposes. The needles/ cannulas may be used during all biopsy and puncturing procedures according to the physician´s indication. Additionally fluids for example for fluoroscopy may be injected.

Cannulas/ needles enhanced for ultrasound visibility are standard cannulas/ needles equipped with CornerStone reflectors (cleared in K111374 - SonoPlex STIM) in order to significantly enhance ultrasound visibility.

The cannulas basically consist of stainless steel tubing and an epoxy glued polycarbonate hub.

In order to enhance ultrasound visibility the cannulas are equipped with a special reflector pattern named "CornerStone" imprinted to the cannulas surface. These reflectors are designed to optimally reflect ultrasound waves.

#### Predicate Devices:

Predicate device with identical indications of use are: - - -------

- 1) K063697 SPECIAL SPROTTE, CHIBA, DR STEINHOFF KIT PAJUNK® GmbH Medizintechnologie, Geisingen
The detailed discussion of substantial equivalence can be found in Section 12 of this submission.

#### Sterilization

The contract sterilizer and the sterilizing process are identical to the process and sterilizer used for all PAJUNK® - manufactured and purchased devices which are already cleared for market or exempt. CornerStone-technique does neither influence sterilization process nor shelf life properties.

Cleaning and Sterilization method, which ensures an SAL of 10th as compliance with limits for chemical burden, bioburden, pyroburden (i.e. LAL) and EtO-residuals as well as shelf life have been validated and are safe and effective.

Efficacy of sterile product's lifecycle has been validated for a period of 10 years now. Shelf life is set to 5 years.

# Biocompatibility:

All cannulas comply with ISO 10993-1, 20d and 3rd edition.

The stainless steel tubing of the Sono-needles/cannulas is identical to stainless steel tubing of the needles/cannulas as they were cleared for market in K063697 in formulation, processing, and sterilization, and no other chemicals have been added (e.g., plasticizers, fillers, color additives, cleaning agents, mold release agents, etc.).

The polycarbonate hub of the Sono-needles/cannulas is identical to the polycarbonate hub of the needles/cannulas as they were cleared for market in K063697 in formulation, processing, and sterilization, and no other chemicals have been added (e.g., plasticizers, fillers, color additives, cleaning agents, mold release agents, etc.).

The epoxy resin glue of the Sono-needles/cannulas is identical to the epoxy resin glue of the needles/cannulas as they were cleared for market in K063697 in formulation, processing, and sterilization, and no other chemicals have been added (e.g., plasticizers, fillers, color additives, cleaning agents, mold release agents, etc.).

The optional polymeric NanoLine coating of the Sono-needles/cannulas is identical to the polymeric NanoLine coating of the NanoLine-needles/cannulas as they were cleared for market in K053283 in formulation, processing, and sterilization, and no other chemicals have been added (e.g., plasticizers, fillers, color additives, cleaning agents, mold release agents, etc.).

### Technology Characteristics:

The components are listed in a table in section 11 of this submission. Shelf life and impact of sterilization and storage on the devices has been proven and found to be safe and effective.

#### Performance Testing

The needles/ cannulas have been subjected to standard testing applicable for all cannulas. Standard testing consists of bending stability and breaking resistance testing as well as of hubto-needle-bondage testing. Due to technological equivalence the subject device is tested the same way as each cannula is tested at PAJUNK® GmbH Medizintechnologie. There are no special testing requirements defined, neither in incoming and in-process inspection routines nor in final testing.

#### Conclusion:

The comparison between the predicate devices and the subject device in section 12 of this submission as well as the validated sterilization process and the results of the bench testing and bench marking demonstrates that the proposed devices are substantially equivalent to the predicate devices and identical in technical description to devices already cleared for market and therefore demonstrated to be safe and effective.

Based on the clinical evaluation, the biocompatibility testing and the bench testing conducted, safety and effectiveness as well as efficacy of the Cornerstone -technique is demonstrated for each type of cannula.
