Cervos Medical · distributed in Australia by RehaCare
Bone marrow aspiration, without the centrifuge.
Marrow Cellution™ draws aspirate straight from undisturbed cancellous bone through a closed distal tip and precision side ports — so peripheral blood never dilutes the yield. Harvest to application in about two minutes, inside a single sterile field.

Overview
Concentration at the point of harvest.
Conventional bone marrow aspiration pulls through an open needle end from a single fixed point, drawing peripheral blood in alongside marrow and then relying on a centrifuge to sort it out afterwards. Marrow Cellution moves the work upstream: the tip is closed, the draw is lateral, and a 360° turn of the handle relocates the cannula into fresh undisturbed bone without a second access site.
The result is aspirate that is ready to apply the moment it is drawn — no processing bench, no capital equipment, no handoff out of the sterile field.
Pairs with high dose PRP in the same clinic
Many practices running bone marrow aspirate also run platelet-rich plasma. KeyPRP™ is the companion Cervos system, built to reach the 10 billion platelet benchmark.

The design difference
An open needle tip drains the wrong thing.
Conventional trocar · open tip
Everything enters through one hole
Aspiration is unrestricted at the open end, so blood from the vascular space is drawn in with the marrow — from one anatomical point, with cell counts falling the longer you pull.
Marrow Cellution™ · closed tip, side ports
100% of the draw goes through the side ports
The closed distal tip blocks the peripheral-blood pathway. Aspiration happens laterally, into undisturbed cancellous bone — and a 360° turn of the handle relocates the cannula to a fresh region without a second access site.
Device anatomy
Four parts. Each one doing a job.
A single-use kit, packaged sterile, ready to open on the field.
01 — Safety
Blunt stylet
Runs inside the cannula so the sharp stylet can't advance past the tip as you go deeper.
02 — Relocation
Screw mechanism
One 360° turn of the handle steps the cannula into a new region of undisturbed bone. No re-stick.
03 — Stability
Outer cannula
Seats against the cortical bone and gives you leverage while you aspirate.
04 — Harvest
Dual aspiration cannula
Closed distal tip, precision lateral side ports. The reason the yield isn't diluted.
Clinical evidence
Aspirate that tracks with cancellous autograft.
Cancellous bone autograft remains the reference standard for osteogenic potential. Across four independent studies (pooled n=37), aspirate obtained with Marrow Cellution sits shoulder to shoulder with it on both CFU-f density and total nucleated cells.

| Study | Device / system | n | CFU-f / mL | TNC ×10⁶ / mL |
|---|---|---|---|---|
| Muschler¹ | Cancellous bone autograft (reference standard) | 10 | 4,564 | 55.7 |
| Lutz⁵ | Marrow Cellution | 22 | 4,838 | 47.0 |

| Bianco² | Marrow Cellution | 5 | 5,309 | 68.5 |
| Pooled | Marrow Cellution | 37 | 5,010 | 50.5 |
Higher CFU-f counts per mL in bone marrow aspirate have been associated with better clinical outcomes, with progenitor cell thresholds identified as a condition for meaningful tissue regeneration.

Theatre time
Two minutes, not twenty.
Because there's no concentration step, the aspirate goes from harvest to application without ever leaving the sterile field.
No capital equipment to buy or service
Centrifuge systems carry upfront cost, servicing schedules and bench space. Every one of those line items disappears — the cost of the procedure is the cost of the disposable.
The sterile field stays closed
Nothing gets handed off for spinning and handed back. Fewer transfer steps, fewer re-entry points, one less contamination pathway to manage.
Fits a clinic, not just a theatre
Single-use, self-contained, no processing bench. Practical for day procedure and outpatient settings where a centrifuge workflow isn't realistic.

Frequently asked
What is centrifuge-free bone marrow aspiration?
Aspiration through a cannula engineered so concentration happens at the point of harvest rather than afterwards. The distal tip is closed and the draw is forced through lateral side ports into undisturbed cancellous bone, which keeps peripheral blood out of the sample at the source. You get a clinically meaningful cell concentration without spinning it — no capital equipment, no handoff out of the sterile field, and none of the 15 to 20 minutes of off-field processing a traditional BMAC workflow needs.
How does it compare to a BMAC system?
On cell counts, closely. Pooled across four independent studies (n=37), aspirate obtained with Marrow Cellution averaged 5,010 CFU-f per mL and 50.5 million total nucleated cells per mL — within the range reported for cancellous bone autograft (4,564 CFU-f/mL; 55.7M TNC/mL). On workflow the difference is larger: roughly two minutes versus about twenty, no centrifuge to buy or maintain, and the whole procedure stays inside one sterile field.
How long does the harvest take?
Around two minutes from access to delivery. There's no concentration step, so the aspirate is ready to apply as soon as it's drawn.
What has bone marrow aspirate been studied in?
Published work using the Marrow Cellution device spans knee and hip osteoarthritis, labral tears, shoulder osteoarthritis, subchondral bone marrow lesions, spinal fusion supplementation and critical limb ischaemia, among others. We can send the full evidence pack — 17+ published studies. Clinical use is always a decision for the treating physician.
Can I get one to trial?
Yes. RehaCare runs product demonstrations for clinicians in Australia and can arrange an evaluation unit. Use the enquiry form above and tell us your procedure type and rough volumes.
