Abstract: A needle assembly for harvesting human eggs, the needle assembly comprising: an outer sleeve having a proximal end and a distal end; a hollow inner needle slidably disposed within the outer sleeve and having: a distal region configured to define a curve; a distal end having a sharpened bevel; a retracted position in which the distal region is disposed within the outer sleeve; and an extended position in which the distal end of the inner needle is distal to the distal end of the outer sleeve and the distal region is at least partially external to the outer sleeve. The needle assembly further comprises a controller configured to move the inner needle between its retracted and extended positions. When the hollow needle is retracted, the distal region conforms to the outer sleeve, and when the inner needle is extended, the distal region defines the curve.
