1. A device for cleaning a stent retriever within a sterile surgical field, comprising
a chamber configured to receive and enclose the stent retriever to be cleaned, the chamber comprising a lid and a bottom, wherein the bottom is shaped as a cup or basin capable of retaining liquid and debris washed from the stent retriever, and wherein the bottom and the lid are attachable with one another to enclose the stent retriever inside the chamber and detachable from one another to insert or remove the stent retriever from the chamber;
at least one port configured for connection with a fluid source to enable inflow and/or outflow of a fluid to or from the chamber; and
one or more support structures comprising a support arm projecting from a wall of the chamber, the support arm comprising a top end positioned entirely inside the chamber and configured to keep hold of the stent retriever in a fixed position inside the chamber and prevent the stent retriever from making contact with walls of the chamber,
wherein the top end of the support arm comprises a cut-out configured to receive and keep hold of a tail wire of the stent retriever, wherein the cut-out is slightly smaller than a size of the tail wire and configured to clip in the tail wire.
