Single-use 8 gauge × 15 cm bone marrow aspiration needle with a non-fenestrated (closed-tip) cannula and a sharp diamond-tip stylet. The large-bore non-fenestrated configuration is intended for protocols requiring distal-tip-only aspiration with high marrow flow.
Caution: Federal (USA) law restricts this device to sale by or on the order of a physician.
The Ranfac RAN-815N is an 8 gauge × 15 centimeter single-use bone marrow aspiration needle with a non-fenestrated (closed-tip) cannula and a sharp diamond-tip stylet. The non-fenestrated configuration limits aspiration to the distal needle tip — preferred where protocol requires single-site marrow draw rather than side-port multi-site sampling. Each needle ships sterile, ethylene-oxide processed, and individually packaged.
RAN-815N is the non-fenestrated companion to the RAN-815 — same large-bore 8 G × 15 cm geometry, with distal-tip-only aspiration where protocol calls for single-site draw. The 25 cm RAN-823CM extends the same large-bore family to deep-anatomy access.
The Ranfac Bone Marrow Aspiration Needle is intended for use in aspirating bone marrow, as determined by a licensed physician.
Practitioners use 8 gauge × 15 cm non-fenestrated bone marrow aspiration needles where the higher flow rate of a larger-bore cannula is required AND single-site distal-tip aspiration is preferred — typically large-volume orthobiologic harvests where side-port draw is not part of protocol.
Diagnostic marrow evaluation, lymphoma and leukemia workups, treatment monitoring, and metastatic staging.
Larger-bore marrow harvest for orthobiologic preparations, bulk aspiration protocols, and applications requiring higher marrow yield per draw.
Image-guided aspiration where single-site large-bore access or controlled marrow draw is preferred.
Used across hospital hematology and oncology suites, ambulatory surgery centers, and procedure rooms performing routine marrow harvests.

The following is a summary only. The complete 10-step Instructions for Use, contraindications, warnings, and disposal requirements are provided in the IFU below.
8 gauge with a 15 cm working length. The cannula is non-fenestrated — aspiration is limited to the distal needle tip.
Same gauge and length. The RAN-815 has a fenestrated cannula (side ports) for multi-site aspiration; RAN-815N is the non-fenestrated companion.
8 G provides a larger lumen and higher marrow flow per draw — typically preferred for orthobiologic preparations and bulk aspiration. For routine diagnostic biopsy, 11 G RAN-1115 or RAN-11 is the standard choice.
Yes. The Ranfac Bone Marrow Aspiration Needle family is cleared under 510(k) K131157, regulation 21 CFR 876.1075, product code KNW, device Class II, prescription-use only.
Sterilized by ethylene oxide (EO) and shipped sterile. The device is not made with natural rubber latex and is intended for single-patient use only.
The female luer-lock hub accepts any standard male luer-lock aspiration syringe. Most operators select 10–20 mL syringes for routine marrow aspiration. Avoid glass syringes — they may not seal properly and can fracture during aspiration.
