Abstract
An expanding needle is provided that includes a tubular body having a proximal end, a needle-tipped distal end, and a lumen extending therebetween. The expanding needle also includes a longitudinal seam formed on the tubular body. The tubular body is configured to uncurl radially, along the longitudinal seam, thereby transitioning the tubular body from a contracted state to an expanded state to increase an inner diameter of the lumen. In certain embodiments, the tubular body is formed by, for example, a continuous flexible sheet rolled in a lengthwise direction. In that case, the longitudinal seam is defined by a portion of a side of the flexible sheet overlapping an opposing side of the flexible sheet. An expanding needle device, including an expanding needle seated to a needle hub, and a method of increasing an inner diameter of an expanding needle are also provided herein.
