Abstract
The present disclosure provides an adjustable delivery handle system for interchangeably delivering a needle to a biopsy site. The adjustable delivery handle system includes a delivery handle having an inner hub housing component configured to interchangeably receive a needle subassembly that can be inserted into and withdrawn from the proximal handle member. The needle subassembly includes a biopsy needle having a distinct tissue collection distal end configured to maximize tissue sampling yield and collect a cohesive unit of sampled tissue. The distal end of the needle 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.
