Study summary

The purpose of this study is to assess the effect of transvenous vagus nerve stimulation (tVNS) on the immune response.

In the human endotoxemia model, intravenously administered endotoxin (lipopolysaccharide [LPS]) elicits a systemic immune response with release of pro-inflammatory cytokines, such as TNF α. This trial will determine if an anti-inflammatory effect can be produced by acute VNS using a minimally invasive delivery method.

Inclusion criteria

Exclusion criteria

Exclusion Criteria:
