## Intended Use

The NanoDrop Lancet is intended for use to obtain a capillary blood sample. It does not collect or transport such samples.

## Device Story

NanoDrop Lancet is a sterile, single-use, disposable device for capillary blood sampling from the upper arm. Device features a gray plastic housing with a bowl-shaped cavity, hydrogel adhesive for skin attachment, and two stainless steel needle blades. Operation involves: 1) attaching device to skin; 2) pressing button 'I' to apply controlled vacuum pressure; 3) pressing button 'II' to deploy needle blades through a septum and vacuum chamber foil. A yellow locking feature prevents accidental deployment. After use, blades automatically retract into the enclosure to prevent reuse and mitigate sharps injury. A permanent plug obstructs the port to prevent unintended connection to collection containers. Used in home or clinical settings by patients or healthcare providers. Output is a capillary blood sample for diagnostic testing. Benefits include safe, controlled, and simplified blood sampling.

## Clinical Evidence

Clinical study evaluated safety, handling, and user opinion of the NanoDrop Lancet compared to the Acti-Lance (K220643). Study included 30 subjects, each providing 4 samples (2 per device). All acceptance criteria were met, supporting safe and effective unsupervised, self-administered use by adults on the upper arm.

## Technological Characteristics

Materials: Stainless steel needles, gray plastic housing, hydrogel adhesive. Principle: Vacuum-assisted capillary blood sampling with dual-blade incision. Dimensions: 17G blades, 0.060in diameter, 0.500in length, 1.9-2.0mm penetration depth. Connectivity: None. Sterilization: Gamma radiation (ISO 11137). Standards: ISO 10993 (biocompatibility), USP <788> (particulates), ASTM F1980 (aging), ASTM F2096 (leaks), ASTM F88 (seal strength).

## Regulatory Identification

The regulation covers four types of blood lancets: (a) Single use only blood lancet with an integral sharps injury prevention feature; (b) Single use only blood lancet without an integral sharps injury prevention feature; (c) Multiple use blood lancet for single patient use only; and (d) Multiple use blood lancet for multiple patient use. All are defined as disposable or reusable devices comprised of a blade attached to a base used to puncture the skin to obtain a drop of blood for diagnostic purposes.

### 5. DEVICE DESCRIPTION

The Drawbridge Health NanoDrop Lancet Device is a sterile, single-use, disposable lancet for capillary blood sampling. The device incorporates two (2) stainless steel needles with blade tips to make two (2) small incisions in the skin. The device is made of a gray plastic housing base that has a molded outer rim and a bowl-shaped cavity. The outer rim is covered by a hydrogeladhesive to better attach the device to the skin, with a cover over the hydrogel adhesive pad for its protection. The bowl shape provides space for the skin to be drawn up as slight controlled vacuum pressure is applied, and for the needle blades to access the skin after piercing through a septum and vacuum chamber foil. There are two (2) clearly marked gray push buttons on the device:

- The gray button marked "I" is for activation of the vacuum; and
- The gray button marked "II" is for deployment of the needle blades.

There is a yellow removable plastic locking feature to prevent accidental activation of the button that deploys the needle blades(gray button marked "II"). There is also a white vacuum chamber lid securely attached on top of the base, over the gray lancet enclosure, where the two needle blades are held in a clear plastic needle holder, along with the main spring and retraction spring, and into which they automatically retract after use, with no access to this gray lancet enclosure possible. This prevents the lancet from being used more than once, and it keeps the blades retracted for sharps injury prevention safety and for disposal. A permanent plug obstructs the port and mitigates unintended connection of a collection container.

The single model number is FD004.

#### 6. INDICATIONS FOR USE

The NanoDrop Lancet device is intended for use to obtain a capillary blood sample. It does not collect or transport such samples.

# Drawbridge

{6}------------------------------------------------

The characteristics of the devices present no material differences in substantial equivalence as the gauge size and number of blades does not affect performance, the difference in method of activation does not affect performance, the penetration depth falls within the range of the predicate device, and the difference in shelf life does not affect performance. The devices are substantially equivalent to each other.

#### 8.4 Animal and Clinical performance data

No animal study is included in this submission.

A clinical study was performed with the aim to evaluate the safety and use of the NanoDrop Lancet Device and to evaluate the user's opinion with regards to handling characteristics of the device as compared to a comparable cleared OTC FMK fingerstick lancet (Acti-Lance K220643). The study included thirty subject with two samples for each device (four samples per subject). All acceptance criteria were met, supporting safe and effective use of the NanoDrop Device unsupervised and self-administered by adults on the upper arm.

## 9. CONCLUSION

The conclusions drawn from the clinical and nonclinical tests demonstrate that the subject device is as safe, as effective, and performs as well as or better than the legally marketed predicate device. They are substantially equivalent to each other.
