Catheter/Stylet Tip Locators, Central Venous

Definition : Devices designed to be used in combination with a catheter/stylet to enable visualization/detection of the catheter tip location, thereby guiding correct positioning/placement of the catheter. These locators typically work in one of two ways: (1) the locator unit emits a type of energy, such as a low-level, high-frequency magnetic field or near infrared light, which is detected by a sensor embedded in a catheter/stylet tip, and is subsequently interpreted and relayed back to the locator, or (2) the catheter/stylet tip emits a type of energy that is detected by a sensor incorporated in the locator-- each is designed to emit/sense the energy as the stylet/central venous catheter (e.g., peripherally inserted central catheter [PICC]) is advanced through the vasculature. These devices are typically hand-held, portable, reusable, and battery-powered. Some locators may consist of several components (e.g., a detector/sensor unit, a visualization module, a stand-alone screen that allows visualization of the catheter tip/stylet, etc.).
