Image guided biopsy needle

A medical device comprising:

• a handle;
• an elongate member extending from the handle, the elongate member defining an elongate member lumen;
• a biopsy needle extending through the elongate member lumen, the biopsy needle defining a biopsy needle lumen;
• an imaging device extending through the biopsy needle lumen, the imaging device moveable between a proximal end of the biopsy needle and a distal end of the biopsy needle;
• an elongate member opening at a distal end of the elongate member;
• a biopsy needle deployment feature proximate to the elongate member opening, wherein the biopsy needle deployment feature is:
• disposed within the elongate member lumen;
• movable, with respect to the elongate member lumen, between a first configuration and a second configuration, and wherein (i) where in the first configuration, the biopsy needle is extendable over the biopsy needle deployment feature and towards the distal end of the elongate member and past the elongate member opening, and (ii) in the second configuration the biopsy needle is moveable through the elongate member opening;
• an actuator mechanism movable within the elongate member lumen and coupled with the biopsy needle deployment feature, wherein the actuator mechanism is extendable within the elongate member lumen to place the biopsy needle deployment feature in the first configuration and the actuator mechanism is retractable within the elongate member lumen to place the biopsy needle deployment feature in the second configuration.

• landmarks at an interior of the biopsy needle and viewable by the imaging device when the imaging device is retracted within the biopsy needle;
• and
• an elongate member recess within the elongate member lumen, the elongate member recess extending from a surface of the elongate member lumen opposite the elongate member opening, the elongate member recess configured to receive a portion of the biopsy needle deployment feature when the biopsy needle deployment feature is in the first configuration where a portion of the biopsy needle deployment feature forms a peak that is planar with the elongate member lumen surface.
