Micropuncture kit for direct vessel access with visual guidance
The patent US12053604B2 describes a micropuncture kit designed for direct access to the lumen of a surgically exposed vessel under direct visual guidance. The kit includes a micropuncture access needle featuring a proximal hub and an elongate shaft with an inner lumen, along with a visible depth indicator positioned at a specific distance from the distal tip. Additionally, the kit comprises an access guidewire that fits through the needle's inner lumen, equipped with its own visible depth indicators. A microaccess cannula is also included, which has multiple visible depth indicators along its elongate body. These indicators serve to visually align the guidewire and cannula, ensuring accurate placement during procedures.
Further details of the kit include specifications for the guidewire's flexibility and structure, with a flexible section at the distal tip and a stiffer core section for support. The guidewire's diameter ranges from 0.014? to 0.018?, while the micropuncture needle's gauge is between 21G and 24G. The visible depth indicators on both the guidewire and cannula are designed to provide precise measurements, with increments typically set at 10 mm. The patent outlines various configurations for these indicators, including chemical-etched, laser-etched, or pad printed markers, enhancing the usability and accuracy of the kit in clinical settings. Overall, the micropuncture kit aims to improve the efficiency and safety of vascular access procedures.
