Abstract

An antimicrobial coating applied to a transdermal surface of a catheter device. An antimicrobial coating applied to catheter device such that when the catheter device is fully inserted, the antimicrobial coating is interposed between the catheter device and the dermal layers of the patient.

Description

technical background [0001] The present invention relates to coatings for skin-invasive devices. In particular, the present invention relates to methods and systems in which an antimicrobial coating is applied to the outer surface of a catheter device to prevent infection. [0002] Catheters are commonly used for a variety of infusion therapies. For example, catheters are used to infuse patients with fluids such as saline solution, various drugs, and total parenteral nutrition; to draw blood from patients; and to monitor various parameters of the patient's vasculature. [0003] Catheters are typically introduced into a patient's vasculature as part of an intravenous catheter assembly. The catheter assembly generally includes a catheter hub, the catheter hub supports the catheter, the catheter hub is connected to a needle hub, and the needle hub supports an introducer needle. The introducer needle is extended and positioned within the catheter such that a beveled portion of ...
