US Patent 7462167 Catheter sheath slitter and method of use

A device and method for slitting a first elongated flexible catheter/sheath used with an elongated flexible component. The device includes a handle, an elongated groove and a cutter member. The cutter member has a sharp distally located cutting edge and a top surface from which a finger projects distally. The cutting edge is located under the finger and is arranged to be located within the annular space between the component and the first catheter/sheath when the first catheter/sheath is within the groove. The cutting edge serves to slice the first catheter/sheath longitudinally when the first catheter/sheath is pulled in a proximal direction. The finger protects the component from injury.
