Wire-embedded polymer-body needle

摘要

A medical needle including an elongate tubular body having an outer wall defining at least one longitudinal lumen is provided. The at least one longitudinal lumen may be configured to provide access for at least one of a wire guide, a therapeutic tool, a diagnostic tool, a medicament, and/or contrast fluid. The body may be configured with sufficient length and flexibility to be extended out of and operated through a working channel of a surgical endoscope. The body further includes one or more wires embedded in, and secured substantially immovably relative to, the outer wall. A distal end of the body includes a needle tip configured with at least one sharpened surface configured to penetrate into body tissue.
