Indications for Use

Indicated for diagnostic ultrasound needle/instrument guided procedures including transvaginal and transrectal tissue biopsy, fluid aspiration, catheter placement, and treatment.

Regulatory Classification

Identification

A diagnostic ultrasonic transducer is a device made of a piezoelectric material that converts electrical signals into acoustic signals and acoustic signals into electrical signals and intended for use in diagnostic ultrasonic medical devices. Accessories of this generic type of device may include transmission media for acoustically coupling the transducer to the body surface, such as acoustic gel, paste, or a flexible fluid container.

Predicate Devices

510(k) Summary con't. - Disposable Endocavity Ultrasound Needle / Biopsy Guide

## Description of Subject Device Submitted for Premarket Notification con't.

The endocavity guide design integrates the mounting bracket and cannula into a single, disposable component that attaches externally, over the transducer with a clip-on action. The removal process is accomplished by pulling the needle guide off the transducer in a reverse method from the application.

Typical guide designs are illustrated below.

Encased Cannula Styles

Open Cannula Styles

Design variables address the mounting features / dimensional characteristics / presentation angle necessary to accommodate differences in transducer geometries, and the cannula size (gauge) as required by the needle / instrument to be guided. Otherwise, needle guide configurations are essentially the same in appearance and function. All guides are designed for conformal fit with locator features for secure alignment to the transducer. Exterior shapes of the needle guide are contoured for patient comfort.

The device is furnished sterile; and the entire guide is single use patient / procedure, disposable. The single use, disposable feature helps to prevent transfer of microorganisms, body fluids, and particulate material to the patient and healthcare worker during reuse of the transducer.

510(k) Summary con't. - Disposable Endocavity Ultrasound Needle / Biopsy Guide

Product categories / models include:
- Disposable Endocavity Needle Guide (sterile)
- Disposable Transrectal Needle Guide (sterile)
- Disposable Transvaginal Needle Guide (sterile)

Endocavity needle guides are individually packaged in sterile "procedure kit" form for single patient / procedure, disposable use. "Procedure kits" are also available with Poly and Latex transducer covers combined with disposable needle guide devices that CIVCO custom kits for ultrasound OEMs.

Intended Uses: This device provides a mechanical means for performing needle / instrument guided procedures with the use of the diagnostic ultrasound endocavity transducer. Needle guide is attached over endocavity transducer / probe / scanhead instruments. This device provides a fixed path for the needle or instrument that when coupled by the ultrasound system software corresponds to on-screen imaging guidelines for visualizing guided instrument placement procedures. CIVCO Endocavity Ultrasound Needle / Biopsy Guides are furnished sterile; single use patient / procedure, disposable. The single use, disposable feature helps to prevent transfer of microorganisms, body fluids, and particulate material to the patient and healthcare worker during reuse of the transducer.

Indications for Use: Diagnostic ultrasound needle / instrument guided procedures - transvaginal and transrectal: tissue biopsy, fluid aspiration, catheter placement, and treatment.

The intended use and indications for use place the CIVCO Disposable Endocavity Ultrasound Needle / Biopsy Guides in device body contact categories as follows:
a) surface devices, intact skin / mucosal membranes / breached surfaces, limited contact duration (< 24 hours)
b) external communicating devices, blood path indirect / tissue communicating, limited contact duration (< 24 hours)

## Comparison of Device to Substantially Equivalent, Legally Marketed Device(s):

Intended Use: both subject and predicate devices provide a mechanical means for performing transrectal and/or transvaginal needle / instrument guided procedures with the use of the diagnostic ultrasound endocavity transducer. This device provides a fixed path for the needle or instrument that when coupled by the ultrasound system software corresponds to on-screen imaging guidelines for visualizing guided instrument placement procedures.

Predicate devices utilize a reusable guide bracket (after cleaning / sterilization by user); and a sterile, single use, disposable cannula insert.

The subject device is furnished sterile; and the entire guide is single use patient / procedure, disposable. The single use, disposable feature helps to prevent transfer of microorganisms, body fluids, and particulate material to the patient and healthcare worker during reuse of the transducer.

Design: Predicate devices are comprised of two components - 1) a reusable guide mount or bracket that securely attaches (wrap-around clamp or slide-on) external to the transducer at a fixed position, and 2) a disposable stainless steel cannula or plastic tube that snap fits into a slot on the reusable component.

The subject device integrates the mounting bracket and cannula into a single, disposable component that attaches externally, over the transducer with a clip-on action. The removal process is accomplished by pulling the needle guide off the transducer in a reverse method from the application.

510(k) Summary con't. - Disposable Endocavity Ultrasound Needle / Blopsy Guide

Comparison of Device to Substantially Equivalent, Legally Marketed Device(s) con't:

Material: Predicate devices: thermoplastics (polycarbonate, nylon, acetal) and stainless steel (T304 Hypodermic Grade tubing).

Subject devices: thermoplastics (ABS, polycarbonate) and stainless steel (T304 Hypodermic Grade tubing). These materials have been effectively used in CIVCO ultrasound endocavity needle guide applications for the past seven (7) years.

Manufacture: Predicate devices: machined fabrications from thermoplastic extruded / molded standard shapes and stainless steel tubing.

Subject devices: fabricated from 1) injection molded thermoplastic components, bonded to stainless steel cannula with medical grade adhesive; and 2) injection insert-molded thermoplastic with integral stainless steel cannula.

Subject devices are manufactured in large lots for single use - disposable applications, and are furnished sterile. Procedure kit packaging (in class 10,000 cleanroom) and EtO sterilization are same as for disposables used with the predicate devices.

Safety: materials and manufacturing processing (including EtO sterilization) affects to the healthcare worker and patient via intended use / indications for use contact of this device have been biologically evaluated using biocompatibility tests for cytotoxicity, acute systemic toxicity, irritation, sensitization, hemolysis, and material mediated pyrogen. Testing is in accordance with ISO 10993-Part 1 Biological Evaluation of Medical Devices, FDA Blue Book Memorandum #G95-1, and FDA-Good Laboratory Practices (GLP). CIVCO Disposable Ultrasound Endocavity Biopsy / Needle Guide products / materials have been evaluated for safe use under device categories of limited contact duration and body contact for surface devices (skin / mucosal membranes / breached surfaces) and body contact for external communicating devices (blood path indirect / tissue communicating). Biocompatibility testing was conducted using sterilized (where applicable), finished devices. Testing has demonstrated subject materials / devices to be non-toxic, non-sensitizing, non-irritating, non-hemolytic, and non-pyrogenic.

Effectiveness: Both the subject and predicate devices guides are designed for secure and aligned fit to the transducer, while not altering the transducer design integrity or function. Positive registration features of the design assures accurate needle / instrument path and placement in relation to the transducer. Attachment and removal of the subject device is simplified vs. the predicate device. Exterior shapes of the needle guides are contoured for patient comfort with no sharp edges. The integrated one-piece design of the subject device improves effectiveness since the reprocessing (clean, disinfect, sterilize) issues for a reusable device such as the predicate device is eliminated by the sterile, single use, disposable feature. Injection molding manufacturing process assures part-to-part accuracy for repeatable product performance.
