Abstract
The dual syringe with percutaneous cannula is a medical device for harvesting and transferring cells for autologous transplantation without the requirement of a surgical setting or ambulatory care. The dual syringe is a closed sterile system that allows for the harvesting syringe to harvest the cells/tissue from a first location of a patient which is then centrifuged to aggregate the cells. The aggregated cell pellet is transferred to a transfer syringe. The cell pellet is then reinjected by the transfer syringe into the patient at a second location for therapeutic purpose. The percutaneous cannula permits insertion of a cannula, with the assistance of a needle, without the need of a surgical incision or trocar.
