Devices and methods for ECG guided vascular access
First Claim
1. A device for ECG guided vascular access, comprising:
- an electrically conductive cannula, with a first cannula end and a second cannula end;
a body, extending from the first cannula end to the second cannula end, having a wall thickness that is greater than a wall thickness of the electrically conductive cannula;
the first cannula end configured to be connected with a vascular access device;
the second cannula end configured to be connected to a syringe; and
an electrically conductive wire with a first wire end and a second wire end, the first wire end being coupled to the electrically conductive cannula, and the second wire end including a nipple connector.

Abstract
A new device and a method are provided which allow for making an electrical connection between an electrolyte and an electric wire. A new connector is provided which allows to be used by a single sterile operator. A new valved device is provided which allows for maintaining the integrity and the pressure of a saline column in the central venous line. A new device is provided which allows for automatically maintaining a continuous flush of a saline syringe in order to allow for keeping the valves of central venous lines open and capable of electric conduction. A new syringe is provided which allows for simultaneous electrical connection between the fluid in the syringe and an electrical wire. Several new methods are provided for making an electrical connection to a central venous line during and after the catheter placement procedure.
