Systems and methods for breaching a sterile field for intravascular placement of a catheter
First Claim
1. A medical device placement system, comprising:
- a medical device assembly including a medical device for placement within a body of a patient and a sensing component, the medical device assembly at least partially disposed in a sterile field, a first connector operably connected to the sensing component including a first contact;
a data-receiving component at least partially disposed in a non-sterile field, a second connector operably connected to the data-receiving component including a second contact; and
means for establishing a conductive pathway between the sterile field and the non-sterile field after the sterile field has been established by creating a perforation in a drape separating the sterile field and the non-sterile field with either the first connector or second connector so as to operably connect the sensing component to the data-receiving component without compromising the sterile field.

Abstract
An integrated catheter placement system for accurately placing a catheter within a patient'"'"'s vasculature is disclosed. In one embodiment, the integrated system comprises a system console, a tip location sensor for temporary placement on the patient'"'"'s chest, and an ultrasound probe. The tip location sensor senses a magnetic field of a stylet disposed in a lumen of the catheter when the catheter is disposed in the vasculature. The ultrasound probe ultrasonically images a portion of the vasculature prior to introduction of the catheter. ECG signal-based catheter tip guidance is included in the integrated system to enable guidance of the catheter tip to a desired position with respect to a node of the patient'"'"'s heart. Various means for establishing a conductive pathway between a sterile field of the patient and a non-sterile field to enable passage of ECG signals from the catheter to the tip location sensor are also disclosed.
