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 CVCs. 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\u2010free boundary layer at the lumen surface. Total protein adsorption is measured under various experimental conditions to further test WISP performance. The WISP device shows reduced protein adsorption as blood and WISP flow rates increase (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.040) with up to a 96% reduction in adsorption over the no WISP condition. When heparin is added to the WISP flow, protein adsorption (0.097[+0.035\/\u20130.055] \u00b5g\/mm<jats:sup>2<\/jats:sup>) is reduced when compared to both bolus administration and nondoped WISP, 0.406(+0.056\/\u20130.065) \u00b5g\/mm<jats:sup>2<\/jats:sup> (<jats:italic>P<\/jats:italic>\u2009=\u20090.001) and 0.191 (+0.076\/\u20130.126) (<jats:italic>P<\/jats:italic>\u2009=\u20090.029), respectively. Additionally, when heparinized WISP is applied to a preadsorbed protein layer, 0.375(+0.114\/\u20130.164) \u00b5g\/mm<jats:sup>2<\/jats:sup>, it displays the ability to reduce the previously\u2010adsorbed protein, 0.186(+0.058\/\u20130.084) \u00b5g\/mm<jats:sup>2<\/jats:sup> (<jats:italic>P<\/jats:italic>\u2009=\u20090.0012), suggesting aptitude for intermittent treatments. The WISP technology not only shows the ability to reduce protein adsorption, but also the ability to remove preadsorbed material by effectively delivering drugs to the point of adsorption; functionalities that could greatly improve clinical outcomes.<\/jats:p>","DOI":"10.1111\/aor.13274","type":"journal-article","created":{"date-parts":[[2018,8,24]],"date-time":"2018-08-24T04:24:37Z","timestamp":1535084677000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Relationship Between Central Venous Catheter Protein Adsorption and Water Infused Surface Protection Mechanisms"],"prefix":"10.1111","volume":"42","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9557-5813","authenticated-orcid":false,"suffix":"Jr","given":"David W.","family":"Sutherland","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering Boston University  Boston MA USA"},{"name":"Biomedical Microsystems Draper  Cambridge MA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zachary D.","family":"Blanks","sequence":"additional","affiliation":[{"name":"Operations Research Center Massachusetts Institute of Technology  Cambridge MA USA"},{"name":"Machine Intelligence Draper  Cambridge MA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering Boston University  Boston MA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph L.","family":"Charest","sequence":"additional","affiliation":[{"name":"Biomedical Microsystems Draper  Cambridge MA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,8,23]]},"reference":[{"key":"e_1_2_8_2_1","volume-title":"US Renal Data System Annual Data Report, ESRD in the United States: Vascular Access","author":"USRDS","year":"2016"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1681\/ASN.2016010019"},{"key":"e_1_2_8_4_1","first-page":"A1158","article-title":"Catheter types at higher risk for central line associated bloodstream infections in the ICU","volume":"195","author":"Ho K","year":"2017","journal-title":"Am J Respir Crit Care Med"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/annonc\/mdt545"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40169-015-0050-9"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.biomaterials.2009.10.008"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-4636(199902)44:2<130::AID-JBM2>3.0.CO;2-9"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.5301\/IJAO.2011.8466"},{"key":"e_1_2_8_10_1","volume-title":"Biomaterials Science: An Introduction to Materials in Medicine","author":"Buddy D","year":"2013"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1681\/ASN.2013091009"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40697-015-0040-2"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1038\/nbt.3020"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/jbm.b.33403"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/jbm.a.30977"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.biomaterials.2015.03.056"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8191.2006.00298.x"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1111\/aor.12916"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00467-005-1876-y"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1525-139X.2010.00770.x"},{"key":"e_1_2_8_21_1","doi-asserted-by":"publisher","DOI":"10.1198\/016214505000000637"},{"key":"e_1_2_8_22_1","unstructured":"R Core Team.R: A Language for Statistical Computing.
