Claims28
A medical system for the preparation of a cell composition, comprising:
- a tube having:
- an anticoagulant;
- a thixotropic gel disposed below the anticoagulant;
- and
- a hyaluronic acid disposed below the thixotropic gel;
- the tube sterilized with the anticoagulant, the thixotropic gel and the hyaluronic acid therein and then hermetically sealed;
- the tube adapted to be centrifuged for a length of time in order to separate platelet rich plasma from whole blood, and to prepare the cell composition including the platelet rich plasma and the hyaluronic acid;
- wherein the tube is sealed with a cap under vacuum pressure to aspirate the whole blood from a patient.

A medical system for the preparation of a cell composition, comprising:
- a tube having:
- a thixotropic gel adapted to separate platelet rich plasma from whole blood;
- an anticoagulant disposed above the thixotropic gel in the tube;
- and
- a hyaluronic acid disposed below the thixotropic gel in the tube;
- the tube adapted to be centrifuged for a length of time in order to separate platelet rich plasma from whole blood, and to prepare the cell composition including the platelet rich plasma and the hyaluronic acid;
- wherein before introduction of the whole blood there are no other additives disposed in the tube other than the thixotropic gel, the anticoagulant, and the hyaluronic acid.

A medical system for the preparation of a cell composition, comprising:
- a tube having:
- an anticoagulant;
- a separator gel disposed below the anticoagulant;
- and
- a hyaluronic acid disposed below the separator gel;
- the tube sterilized with the anticoagulant, the separator gel and the hyaluronic acid therein and then hermetically sealed;
