Systems and methods of delivering a dilated slurry to a patient
First Claim
1. A system for delivering to a patient a cell-slurry comprising a fluid and cells which are non-dissolvable or immiscible in the fluid, the system comprising:
- a container initially containing the cell-slurry and a supernate of the cell-slurry;
a syringe adapted to contain the cell-slurry after dilation with the supernate;
a fluid path between the syringe and the cell-slurry and the supernate in the container, the fluid path comprising a needle at least partially disposed in the cell-slurry and the supernate in the container and tubing fluidly connecting the needle to the syringe;
a plunger disposed in the syringe and adapted to create pressure in the syringe to cause a dilated cell-slurry contained within the container to flow into the syringe through the fluid path; and
a fluidizing system comprising a holder adapted to move the needle to affect dilation of the cell-slurry with a portion of the supernate to form the dilated cell-slurry, the holder and the needle imparting agitating movement to the cell-slurry and the supernate in the container to affect the dilation of the cell-slurry with the supernate.

Abstract
A system for delivering to a patient a slurry which includes a fluid and a material that is non-dissolvable or immiscible in the fluid. The system includes a container adapted to contain the slurry and a supernate of the slurry, a syringe adapted to contain the slurry after dilation with the supermate, a fluid path between the syringe and the contents of the container, the fluid path including a needle at least partially disposed within the contents of the container, a plunger disposed in the syringe and adapted to create pressure in the syringe to cause a dilated slurry to flow into the syringe through the fluid path, and a fluidizing systen associated with the container and comprising a holder adapted to move the needle within the container to affect dilation of the slurry with a portion of the supernate.
