Abstract
A method of providing autologous conditioned plasma (ACP) for treatment of connective tissue injuries. The method comprises the steps of: (i) providing an apparatus comprising a centrifuge and a double syringe, the double syringe including an inner syringe body and an outer syringe body; (ii) drawing autologous blood into the outer syringe body; (iii) subjecting the autologous blood to at least one centrifugation step to obtain an autologous conditioned plasma (ACP); (iv) removing, with the inner syringe body, at least a portion of autologous conditioned plasma (ACP) from the outer syringe body; and (v) inject ACP for treatment of various cartilage or tendon damage or diseases.
Claims18
A method of surgical treatment using autologous conditioned plasma, comprising:
- providing a syringe assembly comprising a first syringe having a first body with a first diameter;
- and a second syringe having a second body with a second diameter smaller than the first diameter, the first syringe being in direct fluid communication with the second syringe;
- withdrawing blood with the first syringe;
- subjecting the syringe assembly to at least one rotational step to obtain an autologous conditioned plasma;
- and
- transferring at least a portion of the autologous conditioned plasma from the first syringe to the second syringe.
A method of treating tissue in a mammal, comprising:
- drawing autologous blood from the mammal;
- subjecting the autologous blood to a centrifugation process to obtain an autologous conditioned plasma and a residual blood component;
- separating the autologous conditioned plasma from the residual blood component;
- and
- injecting the autologous conditioned plasma into the tissue to promote tissue growth.
A method of surgical treatment of connective tissue injury, comprising:
- providing a double-chamber syringe comprising a first chamber having a first body with a first diameter;
- and a second chamber connected to the first chamber and in fluid communication with the first chamber, the second chamber having a second body with a second diameter smaller than the first diameter, the second chamber being located at least partially within the first chamber;
- withdrawing autologous blood with the double-chamber syringe so that the autologous blood is temporarily stored within the first chamber;
- introducing the double-chamber syringe into a centrifuge and centrifuging the double-chamber syringe to obtain an autologous conditioned plasma in the first chamber;
- transferring at least a portion of the autologous conditioned plasma from the first chamber to the second chamber;
- disconnecting the second chamber with the autologous conditioned plasma from the first chamber;
- and
- delivering the autologous conditioned plasma to the connective tissue.
