Representative visualization of flow through the lateral holes of unused and explanted ventricular catheters in a PETG chamber. (A) Schematic of an unused commercial catheter and an explanted catheter in PETG chambers. The lateral hole furthest from the tip is indicated by the red circle. The green circle identifies the location of tissue aggregates on the explanted catheter (B) Five-second long exposure view of microspheres movement into the lateral hole furthest from the catheter tip in a single focus layer. The red arrow indicates the location of the lateral hole. An example of a florescent microsphere is indicated with the blue arrow (C) Three dimensional view of tissue aggregates on an explanted ventricular catheter from Harris Lab shunt bank in a PETG chamber (D) Five-second long exposure view of florescent microsphere movement around tissue aggregates on the lateral hole of an explanted catheter in a single focus layer
