Abstract

A multi-module or single-module cannula device for delivery of stems cells. The multi-module device has at least two cannulas of increasing diameter with larger cannulas encasing smaller cannulas. The single-module device has at least two cannula sections of increasing diameter. Both the multi-module and single-module devices have a first cannula (multi-module) or cannula section (single module) that has an injection end and an attachment end, both of which may be tapered or straight or one of each. The injection end is used for direct entry of the cannula device into a stem cell injection site and the attachment end is used to attach a medical attachment that is used to pump the cells through the device to the injection site. The increasing diameter of the cannulas or cannula sections of the device prevent backflow of the cells onto the exterior of the device. The device maybe used to deliver stem cells to a patient that is undergoing an MRI scan.
