CUTTING DEVICE AND RELATED SYSTEMS AND METHODS

Abstract

Systems, apparatus, and methods are described for forming an incision in tissue for receiving a surgical instrument. A cutting device for forming the incision can be reversibly coupleable to an instrument, e.g., a dilator. The instrument may define a lumen configured to receive a wire that extends or is otherwise extendable through a puncture site. The cutting device can include a cutting element configured to be exposed by a guard to form the incision such that the incision extends form the puncture site and is sized to receive the instrument.
