1. A device for excising tissue, the device comprising:
a suction cup forming a tapered suction chamber comprising a first taper that tapers from a perimeter of the suction chamber at a first height to a center of the suction chamber at a second height less than the first height, enabling a suction force to be applied against the tissue in a first direction, and wherein the suction cup comprises a second taper that tapers continuously from the first height at the perimeter of the suction cup at a proximal end of the suction cup around a circumference of the suction cup to a third height at a distal end of the suction cup, the third height less than the first height and greater than the second height;
a stem coupled to the proximal end of the suction cup via an opening within a tapered side of the suction cup such that a neck of the stem enables flow of fluid to and from the stem into the suction cup in a second direction substantially perpendicular to the first direction, wherein the neck of the suction cup has a first diameter and a proximal end of the stem has a second diameter, and wherein the second diameter is larger than the first diameter; and
a cutting element coupled to an inner surface of the suction cup and configured to excise the tissue.
