Device Facts

• Record ID: K191472
• Device Name: Biopsy Needle
• Applicant: Ushare Medical, Inc.
• Product Code: FCG · Gastroenterology, Urology
• Decision Date: Jan 29, 2020
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 876.1075
• Device Class: Class 2

Intended Use

The Biopsy Needle is intended for use in obtaining core biopsy samples from soft tissue such as kidney, liver, prostrate, spleen, lymph nodes, and various soft tissue masses. Not intended for use in bone. The Biopsy Needle is also indicated to provide breast tissue samples for diagnostic sampling of breast abnormalities. It is designed to provide breast tissue for histologic examination with partial or complete removal of the imaged abnormality. The extent of histologic abnormality cannot be reliably determined from its mammographic appearance. Therefore, the extent of removal of the imaged evidence of an abnormality does not predict the extent of removal of a histologic abnormality (e.g., malignancy). When the sampled abnormality is not histologically benign, it is essential that the tissue margins be examined for completeness of removal using standard surgical procedures.

Device Story

Biopsy Needle; single-use, sterile, disposable device. Input: soft tissue (kidney, liver, prostate, spleen, lymph nodes, breast). Operation: clinician-operated, single-hand automatic activation; guillotine coring mechanism; provides single or two-stage (sequential) automatic advancement for fixed sample length. Output: core tissue sample for histologic evaluation. Used in clinical settings; features include cannula centimeter marks, echogenic radiographic visibility, color-coded hubs, and adjustable depth stops. Benefits: facilitates accurate tissue sampling for diagnosis of abnormalities; allows partial or complete removal of imaged breast abnormalities for examination.

Clinical Evidence

Bench testing only. Performance verified via comparison to predicate device, including firing force, penetration force, biopsy sample quality, and ultrasound visibility. Biocompatibility testing per ISO 10993 series and sterilization validation per ISO 11135/11607 performed.

Technological Characteristics

Stainless steel needle tubing (ISO 9626). Single-use, EO sterilized (ISO 11135). Features: guillotine coring, single-hand automatic activation, echogenic tip, depth stops. Biocompatibility per ISO 10993-1, -4, -5, -10, -11. Dimensions: 14G-20G, lengths 100-200mm.

Indications for Use

Indicated for obtaining core biopsy samples from soft tissue (kidney, liver, prostate, spleen, lymph nodes, masses) and diagnostic sampling of breast abnormalities. Not for use in bone.

The technological characteristics of the subject device are identical to those of predicate device. The subject device has the same basic design as the predicate device. The comparison between the subject and predicate devices is based on the following:

- Same intended use
- Same indications for use
- · Similar material types that meet ISO 10993 biocompatibility requirements
- · Same sterilization methods
- · Same fundamental technology/principal of operation/user interface

The disposable biopsy device needle designs display minor differences between the subject device and the predicate devices for gauge and needle length. The Max and Min size of the current device were covered by the predicate device. There is no significant risk raised by the difference.

#### 8. Conclusion

The analysis of the Current Biopsy Devices by intended use, indications, anatomical locations, and mechanism of action supports that the subject devices are the same as those of the predicate devices.

Needle advancement for the subject device provides a single or two-stage (sequential) automatic advancement for fixed sample length for tissue penetration and cutting same as the predicate device. Materials of construction are those commonly used in medical devices and met biocompatibility requirements for medical devices. The sterile disposable devices also met the requirements for sterility per ISO and USP standards. There are no new questions concerning the safety and effectiveness of these devices.
