The present disclosure provides a cutting assembly for cutting an object, such as a suture, within the body of a patient. The cutting assembly comprises a housing, a proximal cutting element, a distal cutting element, and an actuating member. Both the proximal and distal cutting elements have a cutting surface or blade. The blades face each other within the housing and actuate towards each other to cut the suture. The housing further comprises a plurality of slots that house the blades and maintain them in the orientation desired for cutting. The housing further comprises openings to guide the suture through the cutting assembly. The cutting assembly provides sufficient flexibility to be oriented at the suture location, but maintains its rigidity to effectuate a sufficient, clean cut.
