NEEDLE TIPS, NEEDLES FOR TISSUE COLLECTION, METHODS OF FABRICATION, AND METHODS OF USE

Embodiments of the present disclosure include devices, systems, and methods for acquiring a tissue sample in an endoscopic procedure. In one implementation, a biopsy needle is provided. The biopsy needle includes an elongated body extending along a longitudinal axis. The elongated body includes a lumen extending therethrough and a distal end comprising at least two tines. A heel between adjacent tines comprises an intersection of two cutting surfaces, each comprising a cutting edge having an inclination angle of at least thirty degrees at each point between a first end of the cutting edge and a second end of the cutting edge. For each of the two cutting surfaces, an angle between the cutting surface and an inner surface of the elongated body is not greater than forty-five degrees in a plane that includes the longitudinal axis.
