US Patent 11219447 System and method for suture trimming

Excess suture material may be trimmed after knot tying using a device having an elongated shaft, an elongated tubular cutter disposed over the shaft and an elongated tubular barrel disposed over the cutter. A suture loader at a distal end of the shaft that engages suture material may be opened and closed by a first actuator that causes relative motion between the shaft and the barrel. A second actuator may cause relative motion between the cutter and both of the barrel and the shaft to sever suture material engaged by the closed suture loader.
