• Applicant: Sts Biopolymers
• Product Code: MJG · General, Plastic Surgery
• Decision Date: Jan 20, 1999
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 878.4800
• Device Class: Class 1

Intended Use

The ECHO-COAT™ Ultrasound Needle is indicated for use where improved visibility on ultrasound images is required compared to an uncoated needle. The coated needle also assumes the specific indications for use of the currently marketed uncoated needle, for example biopsy, amniocentesis, vascular access, aspiration, and drainage needles.

Device Story

ECHO-COAT™ Ultrasound Needles consist of commercially available surgical needles (biopsy, aspiration, amniocentesis, etc.; 11-30 gauge; 3-20 cm length) modified with a proprietary polymer coating. Coating enhances needle visibility during ultrasound imaging (1-20 MHz). Device is single-use, EtO sterilized. Used by clinicians in clinical settings to assist in needle positioning during ultrasound-guided procedures. Enhanced visibility aids accurate placement, potentially improving procedural outcomes and reducing complications. No active electronic components; visualization relies on acoustic properties of the polymer coating.

Clinical Evidence

Bench testing only. Testing included sterilization validation, package integrity, biocompatibility, and imaging performance testing to confirm visibility under ultrasound.

Technological Characteristics

Stainless steel needles (various types/gauges) with a proprietary polymer coating for ultrasound visibility. Operates with ultrasound imaging systems (1-20 MHz). Sterilized via Ethylene Oxide (EtO). Standalone manual surgical instrument.

Indications for Use

Indicated for patients requiring ultrasound-guided procedures including biopsy, amniocentesis, vascular access, aspiration, and drainage where enhanced needle visualization is required. No specific age or gender restrictions; contraindications are those of the underlying needle type used.

Regulatory Classification

Identification

A manual surgical instrument for general use is a nonpowered, hand-held, or hand manipulated device, either reusable or disposable, intended to be used in various general surgical procedures. The device includes the applicator, clip applier, biopsy brush, manual dermabrasion brush, scrub brush, cannula, ligature carrier, chisel, clamp, contractor, curette, cutter, dissector, elevator, skin graft expander, file, forceps, gouge, instrument guide, needle guide, hammer, hemostat, amputation hook, ligature passing and knot-tying instrument, knife, mallet, disposable or reusable aspiration and injection needle, disposable or reusable suturing needle, osteotome, pliers, rasp, retainer, retractor, saw, scalpel blade, scalpel handle, one-piece scalpel, snare, spatula, stapler, disposable or reusable stripper, stylet, suturing apparatus for the stomach and intestine, measuring tape, and calipers. A surgical instrument that has specialized uses in a specific medical specialty is classified in separate regulations in parts 868 through 892 of this chapter.

# ECHO-COAT™ Ultrasound Needles

Common/Classification Name: Manual Surgical Instrument, 21 CFR 878.4800

STS Biopolymers, Inc. 336 Summit Point Drive Henrietta, NY 14467

Contact: Michael Violante, Prepared: October 12, 1998

### LEGALLY MARKETED PREDICATE DEVICES A.

The ECHO-COAT™ Ultrasound Needles are substantially equivalent to the Disposable Chiba Biopsy Needle for Use with Ultrasound manufactured by Cook (K851957), as modified with the "EchoTip" for ultrasound imaging visibility.

#### B. DEVICE DESCRIPTION

STS Biopolymers, Inc. will purchase in bulk currently marketed needles designated by application (biopsy, aspiration, amniocentesis, etc.), needle type (spinal, Chiba, Franseen, other), needle gauge (11 to 30), and length (3 to 20 cm), and then apply a polymer coating. The coating, called ECHO-COAT™, is visible in ultrasound images, assisting with positioning. The coated needles will be repackaged as single-use devices, sterilized with EtO, and distributed commercially under the STS Biopolymers, Inc. name.

#### C. INTENDED USE

ECHO-COAT™ Ultrasound Needles are easily visualized on ultrasound images produced by currently available ultrasound imaging devices operating between 1 and 20 MHz. The needles are biocompatible when used according to their intended use. The specific indications for use for the needles purchased for coating will be assumed for the coated product.

#### D. SUBSTANTIAL EQUIVALENCE SUMMARY

The ECHO-COAT™ Ultrasound Needles have similar, but not identical, technological characteristics as the predicate devices. The

could affect safety and effectiveness, e.g., the differences direronooo ooans of the polymer coating as compared to stainless blocomputibility of e o w characteristics do not raise new types of steen. However, and effectiveness questions and there are readily available Salety and offectively biocompatibility tests) to assess the effects of selections tools (significs (the material). STS is providing performance data to demonstrate equivalence where necessary.

# TECHNOLOGICAL CHARACTERISTICS E.

The needles that are purchased for coating by STS Biopolymers, Inc. The neoules that a same technological characteristics as the coated product that will be marketed by STS Biopolymers, Inc.. The additional product that will be coating is new, but it does not raise new types of safety and effectiveness questions. Biocompatibility is required of all needles and can be assured through testing using accepted standards. Ultrasound visibility is obtained through the new coating rather than by etching the surface as in the predicate device. However, there are readily available methods for determining ultrasound visibility also. Through the presentation of the resulting performance data, STS Biopolymers, Inc. has demonstrated that its proposed product is substantially equivalent to the predicate device.

## TESTING F.

STS Biopolymers, Inc. carried out performance testing on the ECHO-COAT™ Ultrasound Needles. This testing addressed the following issues:

- Sterilization (1)
- (2) Package Integrity
- Biocompatibility (3)
- Imaging Performance Testing (4)

All of the results demonstrate substantial equivalence.

## G. CONCLUSIONS

This pre-market submission has demonstrated Substantial Equivalence as defined and understood in the Federal Food Drug and Cosmetic Act and various guidance documents issued by the Center for Devices and Radiological Health.
