ABSTRACT:
A biopsy needle for removal of tissue from a patient includes an outer tube having a distal end and an inner tube disposed within the outer tube. The inner tube has a first section that includes a proximal end thereof, a second section that includes an actuatable snare, and a third section that includes a distal end thereof. The third section is coupled to the outer tube. The snare has a variable diameter that is controlled by rotation of the inner tube with respect to the outer tube in a prescribed direction resulting in the opening and closing, respectively, of the snare. The needle is configured such that the distal end of third section of the inner tube extends beyond the distal end of the outer tube such that the distal end of the inner tube represents a distal tip of the needle.
