Devices and methods obtain and use endovascular electrograms (or electrocardiograms/ECGs) in a number of clinical applications and settings. In one embodiment, a method for locating an indwelling medical device within a vasculature of a patient includes identifying an endovascular ECG waveform complex from an endovascular ECG signal associated with the indwelling medical device, then calculating an absolute value of the energy of the endovascular ECG waveform complex over a predetermined segment thereof. A position of the medical device within the vasculature is then determined by observation of the absolute value of the energy of the predetermined segment of the endovascular ECG waveform complex.

An embodiment is an electromechanical door latch system including a latch device configured for motion between a latched position and an unlatched position. A manually actuated mechanical apparatus is coupled to the latch device and configured to move the latch device to the unlatched position in response to force applied by a user to a component of the mechanical apparatus. An electromechanical actuator system moves the latch device to an actuator unlatched position in response to an electrical signal from an access control device. The electromechanical actuator system includes a control module, a motor, and a ball screw drive including a ball screw or threaded nut, with one coupled to the motor shaft and the other configured for connection to a latch mechanism, and at least one recirculating ball circuit including ball bearings for transferring torque from the motor to the ball screw drive.

A new device and method are introduced herein to facilitate vascular access in general and the placement of central venous access devices in particular. In one embodiment, the device consists of the following components: a wireless ultrasound imaging handheld scanner, a Bluetooth ECG (electrocardiography) data acquisition module with patient ECG cable and sterile adaptor, and a mobile medical application running on a mobile platform (device), e.g., a tablet, smartphone or smart watch. Ultrasound imaging and/or ECG-based catheter guidance provided by the device disclosed herein can be used to independently or simultaneously visualize the catheter in the vasculature and/or guide its placement at the desired location. In another embodiment of the present invention, ultrasound imaging of the blood vessel targeted for vascular access can be used for assessing the blood vessel size prior to cannulating the blood vessel, for guiding an access needle into the targeted blood vessel, and for visualizing the catheter in the vasculature after the introduction of the catheter. In another embodiment of the present invention, ECG-based navigation of an intravascular catheter can be used for tracking such intravascular catheter in the vasculature and positioning such intravascular catheter at a desired location. In one aspect of the present invention, the ultrasound imaging handheld scanner contains all the electronics required to acquire and process ultrasound images and to transfer them wirelessly to a mobile platform device, e.g., a tablet or a smartphone. In another aspect of the present invention, the ECG data acquisition module contains all the electronics required to acquire and process tracking and positioning information for ECG-based catheter guidance and to transfer such information wirelessly to a mobile platform device, e.g., a tablet or a smartphone. In another aspect of the present invention, algorithms are introduced for processing and synchronization of ultrasound images and ECG signals. In another aspect of the present invention, user interfaces for the handheld ultrasound imaging scanner, the ECG data acquisition module, and the mobile medical application running on a mobile platform are introduced in order to simplify the use of ultrasound imaging and/or ECG-based guidance for catheter placement on mobile platforms. In another aspect of the present invention, a new vascular access method is introduced using simultaneous ultrasound imaging and ECG-based catheter guidance. According to the present invention, using ultrasound imaging of a catheter in the vasculature simultaneously with detecting ECG signals at the tip of the catheter provide accurate and reliable catheter location information in adult and pediatric population for most of patients conditions and clinical environments.
