A needle assembly and delivery system for biopsying tissue of a patient includes a flexible biopsy needle, a cannula for receiving and supporting the biopsy needle, and a guide assembly which defines at least one guide assembly for receiving, guiding, and orienting the flexible biopsy needle and cannula through an angle of at least forty degrees through the needle guide assembly to a fixed orientation and position for biopsying tissue of the patient. The biopsy needle includes a sampling section which has smooth or rounded edges, a bending section which has a first circular cross-section, and a body portion proximal of the bending section which has a second circular cross-section larger than the first circular cross-section. The flexible biopsy needle, cannula, and guide assembly may be used with a biopsy ultrasound delivery system which includes an ultrasonic probe and a biopsy gun.
