Background: Silicon nanopore membrane-based implantable bioartificial organs are dependent on arteriovenous implantation of a mechanically robust and biocompatible hemofilter. The hemofilter acts as a low-resistance, high-flow network, with blood flow physiology similar to arteriovenous shunts commonly created for hemodialysis access. A mock circulatory loop (MCL) that mimics shunt physiology is an essential tool for refinement and durability testing of arteriovenous implantable bioartificial organs and silicon blood-interfacing membranes.

We hypothesized that a patient subset could be identified that requires a level of care beyond general surgical training and justifies creation of this new specialty.
Materials And Methods: Reviewed patient admissions over 1-y to the only general surgical service at a level I trauma center-staffed by trauma and/or critical care trained physicians.
