Medtronic has announced that it will be making its MARROWMAX Bone Marrow Aspiration Needle Kit available in the US. The MARROWMAX is designed for extraction of bone marrow and blood, for analysis or to be applied to a synthetic bone graft. Medtronic claims that this new kit can more efficiently draw marrow from the insertion site, which will result in faster aspiration times and greater comfort for patients.
From the press release:
The bone marrow aspiration technique collects marrow and/or autologous blood from a marrow-rich site of the surgeon’s choice. It involves inserting a hollow needle through a skin incision and into the bone marrow cavity. A syringe is then used to draw a sample of the liquid portion of the bone marrow into the hollow needle.
Most bone marrow aspiration needles contain a single hole at the end of the cannula, which is a hollow tube that allows marrow to travel into a syringe, where marrow is drawn from one position. The multi-holed cannula feature of MARROWMAX™ allows for simultaneous marrow draws at the same position thereby reducing aspiration time and the need for sometimes painful repositioning of the needle. MARROWMAX™ comes in three sizes to accommodate surgeons for a variety of draw sites in the body.
