First Claim
Patent Images
1. An antimicrobial catheter device, comprising:
- a catheter having a tip end, a base end, and an extended portion extending therebetween, the catheter further having an outer surface including a transdermal surface and an intravascular surface; and
an antimicrobial agent in the form of a manipulatably adjustable, putty-like matrix applied to the transdermal surface of the outer surface of the catheter, wherein following insertion of the catheter into a patient, a first portion of the antimicrobial agent remains applied to the transdermal surface and is in contact with dermal layers of the patient, and a second portion of the antimicrobial agent is removed from the transdermal surface and deposited external to and surrounding an insertion site into which the catheter is inserted, thereby forming a manually moldable mass of antimicrobial agent proximate to the insertion site.
