Single-use bone marrow aspiration needle with a side-port (fenestrated) cannula and sharp diamond-tip stylet. Designed for multi-site marrow draw without needle repositioning.
Caution: Federal (USA) law restricts this device to sale by or on the order of a physician.
The Ranfac RAN-1115 is an 11 gauge × 15 centimeter single-use bone marrow aspiration needle with a side-port (fenestrated) cannula and a sharp diamond-tip stylet. The fenestrated cannula allows the operator to draw marrow from multiple cortical sites with a single needle pass, reducing the need to reposition the device during sampling. Each needle ships sterile, ethylene-oxide processed, and individually packaged.
Within the Ranfac BMA family, the RAN-1115 is the standard 15 cm fenestrated configuration for routine posterior iliac access where deeper-than-shortest-reach is required. The RAN-1115N is the non-fenestrated companion at the same 11 G × 15 cm size; the RAN-11 covers the same gauge at a shorter 11 cm length; the 8 G RAN-815 is the large-bore option for higher-volume orthobiologic harvests.
The Ranfac Bone Marrow Aspiration Needle is intended for use in aspirating bone marrow, as determined by a licensed physician.
Practitioners use 11 gauge × 15 cm bone marrow aspiration needles for diagnostic and therapeutic marrow harvest from the posterior superior iliac spine, anterior iliac crest, and other accessible marrow cavities. The 15 cm working length accommodates deeper access in larger anatomy. The side-port (fenestrated) cannula design supports multi-site sampling within a single needle pass — useful for hematology workups, oncology staging, and protocols that require larger or pooled marrow volumes.
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 deeper access or multi-site 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 a 15 cm working length. The fenestrated cannula has side ports along the distal segment to permit multi-site marrow aspiration without repositioning the needle.
Fenestrated. The cannula features side ports for multi-site aspiration. If you need an equivalent non-fenestrated configuration in the same size, the RAN-1115N (part 74066-15M) is the non-fenestrated companion.
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.
A sharp diamond-tip stylet with a luer-lock cap. For variants that include a blunt-stylet exchange, see the RAN-11B and related configurations in the bone-marrow portfolio.
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.
