Specialty 11 gauge × 6 inch SNARECOIL™ bone marrow biopsy needle. Same patented captive-mechanism handle as the standard SNARECOIL™ family in a distinct configuration. Specific specialty designation — confirm with Ranfac sales for the intended use case.
Caution: Federal (USA) law restricts this device to sale by or on the order of a physician.
The Ranfac RBN-114S is a specialty 11 gauge × 6 inch single-use bone marrow biopsy needle in the patented SNARECOIL™ family. The 6-inch working length accommodates deeper anatomy than the standard RBN-114 (4 inch). The ergonomic handle includes a captive-mechanism lever (gray OPEN/CLOSED indicator) that engages the specimen at the distal cannula tip for long, intact core recovery.
RBN-114S is a specialty 11 G × 6 inch SNARECOIL™ variant, supplied for OEM and private-label programs. The standard catalog 6 inch configuration at the same gauge is the RBN-116; the more common 4 inch RBN-114 covers routine diagnostic biopsy.
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.
11 gauge × 6 inch SNARECOIL™ configurations are used in posterior iliac crest biopsy where deeper cortical access is required (e.g., higher-BMI patients) and a captive specimen-retention mechanism is preferred to support long, intact core recovery. Per the 29024-01P Rev J Instructions for Use, the device is contraindicated for sternal procedures.
6-inch working length supports deeper cortical access in higher-BMI patients.
Lymphoma, leukemia, MDS, multiple myeloma workups requiring intact core specimens.
Long, non-fragmented cores reduce specimen-handling artifacts during fixation and sectioning.
Long, intact cores reduce specimen-handling artifacts during fixation, sectioning, and immunohistochemistry — supporting accurate, reproducible reads.
