Hematology and oncology services across Health New Zealand (Te Whatu Ora) hospitals—including Auckland City Hospital, Wellington Regional Hospital, and Christchurch Hospital—perform thousands of bone marrow biopsies for diagnostic staging of leukemia, lymphoma, and multiple myeloma. Clinicians require Jamshidi-pattern needles that reliably penetrate dense iliac cortical bone while preserving intact trabecular architecture without crush artifacts. Sourcing requires compliance with Medsafe WAND registration and PHARMAC national medical device framework contracts.
Comprehensive clinical and regulatory guide for New Zealand District Health Boards (Health New Zealand / Te Whatu Ora), hematology clinics, and distributors importing Jamshidi-style bone marrow needles under Medsafe and PHARMAC agreements.
Manshav Impex supplies ISO 13485-certified biopsy systems directly to the Port of Auckland. Request Medsafe regulatory files or explore our specialized needles range.
Bone marrow biopsy of the posterior superior iliac spine requires penetrating dense cortical bone to obtain an intact, uncrushed trabecular core specimen. Manshav Impex Jamshidi-pattern needles are precision-machined from surgical-grade AISI 304/316 stainless steel with an ultra-sharp, hand-finished 4-point trocar or crown-cutting bevel. The internal lumen features an inverted taper: slightly narrower at the distal tip and widening toward the shaft. This allows the bone core to glide smoothly into the cannula without frictional compression or tissue crushing.
To eliminate sample loss during needle withdrawal, our biopsy systems include an internal core extraction cannula (marrow catcher) and an ejector probe with marked centimeter graduations. The ergonomic two-piece T-handle fits naturally into the clinician's palm, providing high rotational torque and axial thrust control while reducing operator hand fatigue during tough cortical bone penetration.
| Design Parameter | Manshav Impex Jamshidi-Style Biopsy Needle | Standard Commodity Bone Needles |
|---|---|---|
| Core Specimen Architecture | Inverted taper lumen (Zero tissue crush artifact) | Cylindrical straight lumen (Crushes bone trabeculae) |
| Cutting Tip Geometry | Quad-facet trocar or sharp scalloped crown | Single bevel (Requires excessive manual force) |
| Sample Capture System | Included internal snare / extraction cannula | No extractor (Core often lost upon needle removal) |
| Handle Ergonomics | Dual-locking ergonomic T-handle with Luer port | Flat stamped handle causing palm bruising |
| Available Gauges | 8G, 11G, 13G (Length: 100mm, 150mm) | Limited sizes, inconsistent internal diameters |
| New Zealand Sea Freight | 20–26 days direct ocean voyage to Auckland Port | 35+ days with multiple Pacific hub transfers |
In New Zealand, medical devices are regulated by the Medicines and Medical Devices Safety Authority (Medsafe). Importers must notify medical devices on the Web Assisted Notification of Devices (WAND) database within 30 days of commercial supply. To participate in Health New Zealand hospital supply agreements managed by PHARMAC (Pharmaceutical Management Agency), manufacturers must supply an audited ISO 13485:2016 certificate, recognized CE marking under EU MDR, biocompatibility data (ISO 10993), and sterilization validation certificates (ISO 11135 / ISO 11137).
Consignments sail from Port Mundra (INMUN1) or Nhava Sheva (INNSA1) across Asia-Pacific maritime routes, docking at Ports of Auckland (NZAKL) or Lyttelton (Christchurch) in 20 to 26 days. Each needle is packed in a rigid sterile blister pack containing the needle, stylet, extraction cannula, and graduated core ejector probe, organized 10 units per inner dispenser box and 100 units per outer shipper carton.
We manufacture 8G and 11G needles for adult posterior iliac biopsies, and 13G needles for pediatric hematology, with luer-lock aspiration adapters. Contact our New Zealand desk.
Obtaining an intact 20mm marrow core without crush artifacts is crucial for accurate immunohistochemistry and staging in lymphoma or myeloma. The internal extraction cannula ensures you never have to re-biopsy a patient due to dropped specimen.
Aspiration draws liquid marrow blood using a syringe attached to the needle's Luer hub for cytology and flow cytometry; core biopsy removes an intact cylindrical bone specimen for histological architecture analysis.
An 11G needle (100mm or 150mm length) is the clinical standard for adult iliac crest biopsies, providing an optimal specimen volume with minimal patient discomfort.
The extraction cannula is inserted through the needle after bone penetration; it grips the marrow core at the base so that twisting the needle cleanly severs the specimen and keeps it inside the cannula.
New Zealand operates a post-market notification system via the WAND database, but products must possess international certification (such as CE or TGA) and satisfy Health New Zealand tender criteria.
