Relationship Between Central Venous Catheter Protein Adsorption and Water Infused Surface Protection Mechanisms

Abstract: Central venous catheters (CVCs) are implanted in the majority of dialysis patients despite increased patient risk due to thrombotic occlusion and biofilm formation. Current solutions remain ineffective at preventing these complications and treatment options are limited and often harmful. We present further analysis of the previously proposed water infused surface protection (WISP) technology, an active method to reduce protein adsorption and effectively disrupt adsorbed protein sheaths on the inner surface of … Show more

“…David W. Sutherland et al of Boston University, Boston, MA, USA, investigated the relationship between central venous catheter (CVC) protein adsorption and water infused surface protection (WISP) mechanisms. A WISP CVC is modeled by a hollow fiber membrane (HFM) in a benchtop device which continuously infuses a saline solution across the membrane wall into the blood flow, creating a blood‐free boundary layer at the lumen surface.…”

“…Protein adsorption is an ubiquitous biological process, such as in protein interaction with biological membranes, and formation of microbial biofilms . The adsorption of proteins on abiotic solid surfaces is also very important for many applications, such as medical and dental practice, e.g., implants, catheters; biomedical research, e.g., drug delivery and release; and devices for diagnostics and drug discovery, e.g., assays, microarrays, and lab-on-a-chip. , Importantly, in most of these instances, and depending on the specific interest, protein adsorption can be either beneficial or deleterious. For instance, high-throughput proteomic microarrays require both a robust immobilization of various proteins on the chip surface and the preservation of their native conformationoften contradictory desiderata.…”
