1. A medical device for creating elongated incisions within soft tissue, the medical device comprising:
a handle having an actuating member;
a flexible shaft having a near end coupled to the handle and a far end;
a cutting member secured within the flexible shaft and having a cutting edge; and
a strut on the flexible shaft and opposite to the cutting member, where the strut expands away from the flexible shaft to provide a biasing force opposite to the cutting member;
a linking member coupling the actuating member of the handle to the cutting member, wherein when the actuating member transfers a tensile force to the linking member, the cutting member pivots out of a lateral side of the flexible shaft exposing the cutting edge without moving axially, which allows cutting of the soft tissue, the tensile force also causing biasing of the far end of the flexible shaft towards the lateral side to assist in maintaining the cutting edge within the soft tissue when cutting the soft tissue.
