Abstract

Inexpensive nitric oxide (NO) release strategies to prevent thrombosis and bacterial infections are desirable for implantable medical devices. Herein, we demonstrate the utility of electrochemically modulated NO release from a catheter model using an inner copper wire working electrode and an inorganic nitrite salt solution reservoir. These catheters generate NO surface fluxes of >1.0 × 10(-10)mol min(-1) cm(-2) for more than 60 h. Catheters with an NO flux of 1.1 × 10(-10)mol min(-1) cm(-2) are shown to significantly reduce surface thrombus formation when implanted in rabbit veins for 7h. Further, the ability of these catheters to exhibit anti-biofilm properties against bacterial species commonly causing bloodstream and urinary catheter infections is examined. Catheters releasing NO continuously during the 2d growth of Staphylococcus aureus exhibit a 6 log-unit reduction in viable surface bacteria. We also demonstrate that catheters generating NO for only 3h at a flux of 1.0 × 10(-10)mol min(-1) cm(-2) lower the live bacterial counts of both 2d and 4d pre-formed Escherichia coli biofilms by >99.9%. Overall, the new electrochemical NO-release devices could provide a cost-effective strategy to greatly enhance the biocompatibility and antimicrobial properties of intravascular and urinary catheters, as well as other implantable medical devices.

  • Nitrite can generate NO via electrochemical reduction at an electrode surface using Cu(I) from Cu0 oxidation or Cu(II)-ligand complexes mimicking nitrite reductase.

    “Recently, it was demonstrated that nitrite can also be used to generate NO via electrochemical reduction at an electrode surface with either Cu(I) ion generated from oxidation of Cu0145,146 or via the use of Cu(II)-ligand complexes that mimic the active site of nitrite reductase (e.g., Cu(II)-tri(2-pyridylmethyl)amine, Cu(II)TPMA).147”
  • NO releasing or generating polymers can have strong bactericidal effects, even for bacteria able to metabolize and deactivate NO, such as P. aeruginosa with NO reductase.

    “It has been clearly demonstrated that NO releasing/generating polymers can have strong bactericidal effects,19,146,147,162,201,227,283,284 even for bacteria that are able to metabolize and deactivate NO, such as P. aeruginosa, that possesses NO reductase enzyme that converts NO to nitrous oxide (N2O) and ultimately nitrogen (N2).86,201,219”
  • Electrochemical NO generating catheters using an inner copper wire working electrode and inorganic nitrite salt solution can generate NO through catheter walls with a flux > 1.0 × 10−10 mol cm−2 min−1 for more than 60 h.

    “Electrochemical NO generating catheters using inner copper wire working electrode and inorganic nitrite salt solution can generate NO through the walls of the catheters with a flux > 1.0 × 10−10 mol cm−2 min−1 for more than 60 h.146”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
