Indications for Use

Model 121 Biopsy Needle is intended for obtaining percutaneous or surgical histological core samples from soft tissues such as breast, kidney, liver, lung and various soft tissue masses. The device is not intended for use in bone. Model 111/112 Biopsy Needle is intended for obtaining core biopsy from samples soft tissues such as kidney, liver, prostate and various soft tissue masses. The device is not intended for use in bone. Model 111/112 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 abnormality. Model 131 Disposable Coaxial Biopsy Needle is intended for use with biopsy needle during soft tissue core biopsy procedures. The device is not intended for use in bone. The extent of histological abnormality cannot be reliably determined from it mammographic appearance. Therefore the extent of removal of the imaged evidence of an abnormality does not predict the extent of removal of a histological abnormality (e.g. malignancy). When the sampled abnormality is not histologically benign, it is essue margins be examined for completeness of removal using standard surgical procedures.

Device Story

Disposable semi-automatic and automatic spring-powered biopsy needles; used to obtain histological core samples from soft tissues. Input: manual operation by clinician; device transforms mechanical spring energy into rapid needle advancement (guillotine style) to capture tissue. Output: tissue core sample for histologic examination. Used in clinical settings for diagnostic sampling of abnormalities. Model 131 acts as a coaxial introducer for biopsy needles. Benefits: enables minimally invasive tissue acquisition for diagnosis; aids in determining malignancy or benign status of soft tissue abnormalities.

Clinical Evidence

No clinical data. Bench testing only. Performance evaluated via mechanical testing (depth projection, penetration force, activation force, mechanical durability, sample extraction) compared to predicate devices. Biocompatibility testing per ISO 10993-1:2018 (cytotoxicity, sensitization, irritation, systemic toxicity, hemolysis). Sterilization validated per ISO 11135.

Technological Characteristics

Materials: 304 stainless steel (X5CrNi18-9). Design: Disposable, spring-powered, semi-automatic/automatic biopsy needles. Gauge: 14G-20G (biopsy), 15G-19G (coaxial). Length: 47mm-250mm. Energy: Mechanical spring. Sterilization: Ethylene Oxide (EO). Connectivity: None. Standards: ISO 9626 (needle performance), ISO 10993 (biocompatibility), ASTM F3014 (penetration force).

Indications for Use

Indicated for individuals requiring percutaneous or surgical histological core biopsy of soft tissue masses (breast, kidney, liver, lung, prostate, spleen, lymph nodes). Not for use in bone.
