Single-use 11 gauge × 11 cm bone marrow aspiration needle with a side-port (fenestrated) cannula and an extra-blunt stylet. The blunt-stylet configuration supports needle exchange or re-entry techniques where sharp-tip penetration is undesirable.
Caution: Federal (USA) law restricts this device to sale by or on the order of a physician.
The Ranfac RAN-11B is an 11 gauge × 11 centimeter single-use bone marrow aspiration needle with a side-port (fenestrated) cannula and an extra-blunt stylet. The blunt-stylet configuration is intended for procedures that include needle exchange or re-entry into a previously established tract, where a sharp diamond-tip stylet is not appropriate. Each needle ships sterile, ethylene-oxide processed, and individually packaged.
RAN-11B is the extra-blunt-stylet variant of the RAN-11, intended for procedures that include needle exchange or re-entry where a sharp diamond-tip stylet is not appropriate. The cannula itself remains fenestrated, so multi-site aspiration capability is preserved.
The Ranfac Bone Marrow Aspiration Needle is intended for use in aspirating bone marrow, as determined by a licensed physician.
The extra-blunt stylet supports needle exchange or re-entry protocols in marrow aspiration, where a sharp stylet would risk additional cortical or soft-tissue trauma. The fenestrated cannula retains the multi-site draw capability of the standard RAN-11.
Diagnostic marrow evaluation, lymphoma and leukemia workups, treatment monitoring, and metastatic staging.
Marrow harvest for orthobiologic preparations used adjunctively to surgical procedures, per physician direction.
Image-guided aspiration where exchange-compatible access or controlled marrow draw is preferred.
Used across hospital hematology and oncology suites, ambulatory surgery centers, and procedure rooms performing routine marrow harvests.

An extra-blunt stylet — designed for procedures where needle exchange or re-entry is required and a sharp diamond-tip would risk additional trauma. The cannula itself remains fenestrated.
Same gauge, length, and fenestrated cannula. The RAN-11 ships with a sharp diamond-tip stylet for initial cortical penetration. RAN-11B ships with an extra-blunt stylet for exchange/re-entry.
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 Ranfac BMA portfolio includes sharp diamond-tip configurations (e.g. RAN-1115) and trocar-tip configurations (e.g. RAN-823CM). For custom stylet geometries, contact us about an OEM program.
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.
