Single-use 11 gauge × 11 cm bone marrow aspiration needle with side-port (fenestrated) cannula and sharp diamond-tip stylet. The shorter working length is suited to posterior iliac access where deeper penetration is not required.
Caution: Federal (USA) law restricts this device to sale by or on the order of a physician.
The Ranfac RAN-11 is an 11 gauge × 11 centimeter single-use bone marrow aspiration needle with a side-port (fenestrated) cannula and a sharp diamond-tip stylet. The 11 cm working length is the standard short-length variant for posterior iliac access; the 15 cm RAN-1115 is the deeper-access companion in the same fenestrated configuration. Each needle ships sterile, ethylene-oxide processed, and individually packaged.
RAN-11 is the standard short-length 11 G fenestrated configuration for posterior iliac access where the 15 cm RAN-1115 is more reach than the procedure requires. The RAN-11N is the non-fenestrated companion at the same size; the RAN-11B substitutes an extra-blunt stylet for exchange and re-entry protocols.
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 bone marrow aspiration needles for diagnostic and therapeutic marrow harvest from the posterior superior iliac spine and anterior iliac crest, where deeper access is not required. The side-port (fenestrated) cannula supports multi-site sampling within a single needle pass.
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 shorter access or controlled marrow draw is preferred.
Used across hospital hematology and oncology suites, ambulatory surgery centers, and procedure rooms performing routine marrow harvests.

11 gauge with an 11 cm working length. The fenestrated cannula has side ports along the distal segment to permit multi-site marrow aspiration without repositioning the needle.
Same gauge and same fenestrated configuration — the RAN-11 has an 11 cm working length, the RAN-1115 has a 15 cm working length for deeper access.
Yes — the RAN-11N (part 74066-01M) is the non-fenestrated companion at the same 11 G × 11 cm size.
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.
