Intended Use

Spinal needles are indicated for the injection of local anesthetics into a patient to provide regional anesthesia.

Device Story

Spinal anesthesia needles and introducer needles; used for regional anesthesia delivery. Device consists of luer hub, stainless steel cannula, and stainless steel stylet. Available in Lancet (Quincke), Pencil (Whitacre), and European (Sprotte) styles. Introducer needles (18g or 20g) facilitate initial skin puncture. Sterile, single-use, disposable. Operated by clinicians in clinical settings. Design features increased inside diameter, reduced outside diameter/wall thickness, and improved cannula strength compared to predicates. Provides faster flashback and reduced penetration force. Output is delivery of anesthetic agent to patient; aids in regional anesthesia procedures.

Clinical Evidence

Bench testing only. Comparison of flow rates, flashback speed, and penetration force between subject needles and predicate devices. Results showed increased inside diameter, reduced penetration force (up to 32.8% for Whitacre style), and improved or similar flashback performance compared to predicates.

Technological Characteristics

Materials: Stainless steel cannula and stylet, luer hub. Design: Lancet, Pencil, and European styles. Dimensions: 18g-25g gauge, 2.0"-6.0" length. Introducer needles: 18g or 20g. Sterile, single-use, disposable. No software or electronic components.

Indications for Use

Indicated for patients requiring regional anesthesia via injection of local anesthetics.

Regulatory Classification

Spinal Anesthesia Needles

Spinal Anesthesia Needles

# PRODUCT CLASS/CLASSIFICATION:

Class II, 80 MIA, 21 CFR 862.5150

{1}------------------------------------------------

#### PREDICATE DEVICE(S):

Becton-Dickinson spinal needles, marketed as preamendment devices.

- Pajunk Medizintechnologie, Germany, Sprotte spinal needles, marketed under 510(k) K911221 and K911202.
- Preferred Medical Products ( a division of Ballard Medical Products), spinal needles purchased from Unisis Corp., Tokyo, Japan, marketed under K885277.

Sherwood Medical, introducer needle, marketed as preamendment device.

American Medical Instruments, Inc., New Bedford, MA, introducer needles, marketed as preamendment devices.

## DESCRIPTION:

A spinal needle is an instrument used for the injection of local anesthetics into a patient to provide regional anesthesia. The needle consists of a luer hub, a stainless steel cannula, and a stainless steel stylete. The needles are provided as sterile, single use, disposable devices. They may be packaged individually or included in our regional anesthesia trays. The spinal needles are provided in three styles; Lancet Point (Quincke), Pencil Point (Whitacre), and European Style (Sprotte) (refer to drawings, attachment IX). The needles range in size as indicated in the following table:

| Needle Style | Gage Size Range | Length Range |
|----------------|-----------------|--------------|
| Lancet Point | 18g to 25g | 2.0" to 6.0" |
| Pencil Point | 22g to 25g | 2.0" to 6.0" |
| European Style | 24g to 25g | 2.0" to 6.0" |

The introducer needle is a simple hypodermic needle, either 18g or 20g, to make the initial puncture through the skin to aid in the placement of the spinal needle.

## INDICATIONS FOR USE:

Spinal needles are indicated for the injection of local anesthetics into a patient to provide regional anesthesia.

# TECHNICAL CHARACTERISTICS:

The device has the same technical characteristics as the predicate device marketed by Preferred Medical Products, Becton-Dickinson, Pajunk, Sherwood, and AMI.

# NON-CLINICAL DATA:

To summarize, comparison testing between the proposed device and the predicate devices from Becton Dickinson, Pajunk, Sherwood, and AMI, the proposed devices compared well against the predicate devices. For the spinal needles, overall, an increased inside diameter

{2}------------------------------------------------

was achieved with a reduced outside diameter and wall thickness, while still achieving increased strength of the cannula.

The greater inside diameter allowed for an increased flow rate for all of the Unisis needles tested. The flashback in the European Style (Sprotte) needles was generally quicker for the proposed device. The results of the Quincke (K-3 Lancet) type needles showed similar results for the 18, 20, and 22-gage cannula. The 25-gage cannula showed an improved rate of flashback. The Whitacre (Pencil Point) type needles also showed similar results between the predicate and proposed devices. When the stylete is retracted, the rate of flashback will be further increased.

Finally, the penetration force for all proposed needles was reduced by as much as 32.8% for the Whitacre (Pencil Point) type needle, except for the 22g and 25g Ouincke (K-3 Lancet) type needle, 1.9% and 13.3% respectively.

There are three proposed introducer needles. These compare favorably to the Sherwood and AMI needles for all criteria.

In summary, the differences in these needles are not significant and substantiate that the needles are safe and effective. This testing, and the marketing of the same spinal needles by Preferred Medical Products, substantiates this claim.

# CONCLUSION:

The testing performed and comparison to the predicate devices demonstrate that the proposed devices are safe and effective and are substantially equivalent to the predicate devices.

Very truly yours.
