Abstract
The present disclosure generally relates to a biopsy needle configured to maximize tissue sampling yield and collect a cohesive unit of sampled tissue. The biopsy needle includes an elongate tubular body comprising a lumen extending therethrough from a proximal open end to a distal open end of the body. The distal end includes first and second tip portions extending therefrom and radially opposing one another. The first tip portion has a length greater than the second tip portion, thereby resulting in an increased surface area of a curvilinear cutting edge extending from the first tip portion to the second tip portion. Additionally, each of the first and second tip portions defines a point configured to pierce the tissue to be sampled and further direct tissue towards the lumen of the body to be excised by the cutting edge upon contact therewith.
