Abstract:
1. A system for delivering particles to a patient; the system comprising: an infusion device having a reservoir configured to house the particles; a delivery element having a proximal end, a distal end, a delivery region between the proximal end and the distal end, and a lumen extending from the proximal end to the delivery region, the delivery element being operably couplable to the infusion device such that particles from the reservoir are deliverable via the delivery region of the delivery element, the delivery element comprises a stop feature between the proximal and distal end to prevent a polymeric carrier from being inserted proximally in the lumen beyond the stop feature; a polymeric carrier in the form of a compressed sponge slidably disposed in the lumen such that the carrier is spaced apart from the proximal and distal ends of the delivery element, wherein delivery of the particles from the reservoir via the delivery region of the delivery element causes the polymeric carrier to exit to the delivery region of the delivery element; wherein the particles comprise cells, the cells having a concentration between about 1×10 7 cells/mL and about 1×10 9 cells/mL.
