Single-use 11 gauge × 11 cm bone marrow aspiration needle with a non-fenestrated (closed-tip) cannula and sharp diamond-tip stylet. For protocols that require single-site marrow draw without side-port aspiration.
Caution: Federal (USA) law restricts this device to sale by or on the order of a physician.
The Ranfac RAN-11N is an 11 gauge × 11 centimeter single-use bone marrow aspiration needle with a non-fenestrated (closed-tip) cannula and a sharp diamond-tip stylet. The non-fenestrated configuration is preferred where single-site, distal-tip-only aspiration is required by protocol. Each needle ships sterile, ethylene-oxide processed, and individually packaged.
RAN-11N is the non-fenestrated 11 G × 11 cm companion to the standard RAN-11 — selected when protocol calls for single-site distal-tip aspiration rather than side-port multi-site draw. The 15 cm RAN-1115N is the deeper-reach non-fenestrated option in the same gauge.
The Ranfac Bone Marrow Aspiration Needle is intended for use in aspirating bone marrow, as determined by a licensed physician.
Practitioners use 11 gauge × 11 cm non-fenestrated bone marrow aspiration needles for diagnostic and therapeutic marrow harvest from the posterior superior iliac spine and anterior iliac crest, where single-site distal-tip aspiration is preferred to side-port multi-site draw.
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 single-site 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.
11 gauge with an 11 cm working length. The cannula is non-fenestrated (closed-tip) — aspiration is limited to the distal needle tip rather than side ports.
Same gauge and length — the RAN-11 has a fenestrated cannula (side ports) for multi-site aspiration. RAN-11N is the non-fenestrated companion for single-site draw.
Yes — see the RAN-1115N, the 11 G × 15 cm non-fenestrated configuration in the same family.
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.
