Antimicrobial coating forming kink resistant feature on a vascular access device
First Claim
Patent Images
1. A vascular access device comprising:
- a catheter adapter;
a catheter that extends distally from the catheter adapter and comprises a material; and
an antimicrobial coating applied to at least a portion of the catheter, the antimicrobial coating comprising a base material that releases one or more antimicrobial agents when the antimicrobial coating is inserted within skin of the patient, wherein the base material is UV cured and has a hardness greater than a hardness of the material of the catheter to provide kink resistance to the catheter, wherein the antimicrobial coating is uniform in thickness along a first portion of the catheter, wherein the antimicrobial coating increases in thickness along a second portion of the catheter adjacent the catheter adapter, wherein when the catheter is inserted into a vein of the patient, the first portion is configured to be positioned at least at an intimal layer of the vein and the second portion is configured to be disposed outside a body of the patient at least proximate the outer layers of the skin.

Abstract
A vascular access device includes an antimicrobial coating that provides kink resistance to a catheter. The antimicrobial coating can extend along a length of the catheter to provide antimicrobial protection when the catheter is inserted into the patient'"'"'s vasculature. The antimicrobial coating can also increase the effective diameter of the catheter to minimize the likelihood that the catheter will become kinked.

9. A vascular access device comprising:
-
a catheter adapter; a catheter that extends distally from the catheter adapter; and an antimicrobial coating on the catheter, the antimicrobial coating extending from the catheter adapter towards a distal end of the catheter, the antimicrobial coating comprising a base material that releases one or more antimicrobial agents when the antimicrobial coating is inserted within skin of the patient, wherein the base material is cured such that the base material provides increased rigidity to the catheter, the antimicrobial coating having an increased diameter portion adjacent the catheter adapter, wherein the antimicrobial coating increases in thickness from a distal portion of the catheter to a proximal portion of the catheter proximate a distal end of the catheter adapter. - View Dependent Claims (10, 11)

12. A vascular access device comprising:
-
a catheter adapter; a catheter that extends distally from the catheter adapter; and an antimicrobial coating applied to a portion of the catheter, the antimicrobial coating having a proximal end and a distal end, the antimicrobial coating comprising a base material that releases one or more antimicrobial agents when the antimicrobial coating is positioned within a patient'"'"'s skin, wherein the base material is cured such that the base material provides increased rigidity to the catheter, wherein the antimicrobial coating is uniform in thickness along a first portion of the catheter, wherein the antimicrobial coating increases in thickness along a second portion of the catheter adjacent the catheter adapter, wherein an outer diameter of the antimicrobial coating at a proximal end of the second portion equals an outer diameter of a distal end of the catheter adapter. - View Dependent Claims (13)
