Abstract: A catheter insertion device that allows for single-handed insertion of the catheter within the vasculature of the patient is disclosed. The catheter insertion device includes a handle, a needle cannula partially within the handle, a guidewire partially within the handle and the needle cannula, and a first actuator connected to the handle and the guidewire. The guidewire is movable relative to the handle in a distal direction away from the handle, and in a proximal direction towards the handle. A catheter assembly is removably coupled to the handle and is configured to slide on the needle cannula. A catheter hub may be connected to a proximal end of the catheter, and a catheter advancer base may be releasably connected to the catheter hub. The catheter insertion device may also include a needle support pivotally connected to the handle for supporting the needle cannula on a cantilever portion thereof.

Abstract: A vascular access training simulator system for training intravascular insertion of a medical device is disclosed. The vascular access training simulator system includes an anatomical training model having clinically relevant ultrasonic properties representative of ultrasonic properties of a human body site for ultrasound imaging. The training model includes a transparent housing, a transparent simulated tissue, at least one simulated blood vessel suspended in the tissue, and a layer of simulated skin covering the housing and the tissue. A first imaging device is records a first video showing a view of an insertion site outside of the simulated skin. A second imaging device records a second video showing the simulated blood vessel through the transparent simulated tissue. A third imaging device is shows an ultrasound view of the simulated blood vessel and the simulated tissue. A monitor displays a composite view of all three videos simultaneously on a single screen.

Abstract: An assembly is provided for accessing a superior vena cava of a patient without visualization of a vasculature of the patient. A stylet has an elongated body including a core wire disposed within a tubular body, the core wire having a pre-formed shape in a first state and a straightened shape in a second state. A first portion of the core wire has a substantially straight shape in the first state. A second portion of the core wire has a first pre-formed bend in the first state. A third portion of the core wire has a substantially straight shape in the first state. A fourth portion of the core wire has a second pre-formed bend in the first state. A fifth portion of the core wire has a substantially straight shape in the first state and includes a narrow segment that increases deflection of the distal tip.
