The catheter placement system is configured to assist a clinician in positioning a catheter in a desired location within a body of a patient. In one embodiment, the location sensor assembly comprises a location sensor body for temporary placement on a portion of the patient body, and a connector interface. The connector interface is configured to removably attach to the location sensor and provide a plurality of electrically conductive pathways between the location sensor and additional components of the catheter placement system to enable the additional components to operably connect with the location sensor. The connector interface further includes a first connector configured to operably connect with a second connector of one of the additional components of the catheter placement system through a drape interposed between the first and second connectors. ## Claims ### Claim 1 A connector interface designed to connect components of a catheter placement system to a location sensor of the catheter placement system, the connector interface comprising: a console connection interface designed for mating with a console port of the location sensor; an electrocardiogram (ECG) connection interface plug designed for mating with an ECG port receptacle of the location sensor; and a stylet connection interface designed for mating with a stylet connector recess of the location sensor, wherein the connector interface enables simultaneous mating of the console connection interface, the ECG connection interface plug, and the stylet connection interface to the location sensor. ### Claim 2 (depends on 1) The connector interface according to claim 1, wherein the stylet connection interface comprises a fin portion. ### Claim 3 (depends on 2) The connector interface according to claim 2, wherein the fin portion includes a receptacle configured to receive therein a male connector of an ECG stylet of the catheter placement system. ### Claim 4 (depends on 3) The connector interface according to claim 3, wherein the location sensor includes at least one sensor configured to detect a magnetic element included with the ECG stylet of the catheter placement system. ### Claim 5 (depends on 1) The connector interface according to claim 1, wherein the connector interface further comprises a recess including one or more ECG lead contacts in communication with the ECG connection interface plug. ### Claim 6 (depends on 1) The connector interface according to claim 1, further comprising a USB cable that operably connects the location sensor to a console of the catheter placement system. ### Claim 7 (depends on 6) The connector interface according to claim 6, wherein the USB cable is permanently attached to the connector interface. ### Claim 8 (depends on 1) The connector interface according to claim 1, wherein the location sensor is designed to be temporarily disposed on a chest portion of a patient. ### Claim 9 (depends on 1) The connector interface according to claim 1, wherein the connector interface is removable from the location sensor and is designed for multiple uses. ### Claim 10 (depends on 1) The connector interface according to claim 1, wherein the console connection interface is a universal serial bus (USB) type B plug, and wherein the console port of the location sensor is a USB type B receptacle. ### Claim 11 (depends on 10) The connector interface according to claim 10, wherein the stylet connection interface is a rail, wherein the stylet connector recess of the location sensor is a track, and wherein the rail is designed to slide in the track.
