Abstract:
A biopsy needle for removal of tissue from a patient including an outer tube; an inner tube within the outer tube; and a snare connected to the inner tube and to the outer tube. The outer tube has an outer surface that has a first region that terminates in the distal end and is the distalmost section of the outer tube and a second region adjacent the first region. The first region represents a tip transition region and has a frustoconical shape that is defined by an outer surface area (A) and is defined by a cross-sectional area (Ba) at the interface between the first and second regions in a direction that is perpendicular to the longitudinal axis of the needle, the interface representing a base of the frustoconical first region, wherein a ratio R=(A)/(Ba) is approximately 1 for a predetermined needle type, such as an 8 gauge needle.
