Claims24
A medical device for creating elongated incisions within soft tissue, the device comprising:
- a handle comprising a handle body and an actuating member;
- a shaft assembly comprising a flexible shaft having a near end coupled to the handle body and a far end, the flexible shaft having an axis, the shaft assembly configured to deflect a distal portion of the flexible shaft in a first direction away from the axis;
- a cutting member pivotally secured within the distal portion of the flexible shaft and having a cutting edge;
- a linking member nonparallel to the axis and coupling the actuating member of the handle to the cutting member such that when the linking member is maintained in tension, the cutting member pivots out of an opening in the distal portion of the flexible shaft and towards the first direction to remain outside of the distal portion of the flexible shaft and simultaneously urges the distal portion in the first direction wherein the cutting member pivots about a pivot point that does not move axially relative to the shaft assembly.
