Patented SNARECOIL™ 8 gauge × 6 inch bone marrow biopsy needle. The largest-bore SNARECOIL™ configuration combined with a 6-inch working length — designed for deep posterior iliac crest access with high-volume specimen requirements.
Caution: Federal (USA) law restricts this device to sale by or on the order of a physician.
The Ranfac RBN-86 is an 8 gauge × 6 inch single-use bone marrow biopsy needle in the patented SNARECOIL™ family. It combines the largest bore in the SNARECOIL™ line (8 G) with an extended 6-inch working length — designed for deep posterior iliac crest access where high-volume core specimens are also required.
RBN-86 is the large-bore 8 G × 6 inch SNARECOIL™ configuration — combining the larger-volume 8 G core with extended reach. The 4 inch RBN-84 is the shorter companion at the same gauge.
Per 510(k) K983187: For procuring bone marrow core biopsies from patients with hematologic abnormalities. Per IFU 29024-01P: The Ranfac Bone Marrow Biopsy Needle is indicated for the surgical harvesting of bone marrow.
8 gauge × 6 inch SNARECOIL™ is the deepest, largest-bore configuration in the Ranfac biopsy line. Applications include bariatric or deep-anatomy posterior iliac crest biopsy where larger specimen volume is also clinically required. Per the 29024-01P Rev J Instructions for Use, the device is contraindicated for sternal procedures.
Combines 6-inch reach with the largest SNARECOIL™ bore — for bariatric / deep-anatomy biopsy requiring high-volume cores.
Lymphoma, leukemia, MDS, multiple myeloma workups requiring intact core specimens.
Long, non-fragmented cores suitable for immunohistochemistry, flow cytometry preparation, and research tissue protocols.
Long, intact cores reduce specimen-handling artifacts during fixation, sectioning, and immunohistochemistry — supporting accurate, reproducible reads.

Summary only. The complete 25-step bilingual Instructions for Use (29024-01P Rev J), including contraindications, warnings, and specimen-retrieval technique, accompanies every device and is downloadable below.
Choose RBN-86 when both higher specimen volume (8 G bore) and deeper cortical reach (6-inch length) are required — for example, bariatric posterior iliac crest biopsy on a research or cell-yield protocol. The 11 G × 4 inch RBN-114 remains the most common diagnostic configuration.
SNARECOIL™ is Ranfac's patented captive specimen-capture mechanism. A lever on the ergonomic handle engages the cannula tip to retain the marrow core during withdrawal.
