Abstract

The disclosure relates to transcatheter stented prosthesis delivery devices including a handle assembly connected to a shaft assembly on which a stented prosthesis is loaded and compressively retained with a plurality of elongate tension members. The delivery devices include a cutting assembly that can sever the elongate tension members after the stented prosthesis is expanded at a target site so that the delivery device can be withdrawn from the patient. Certain embodiments position the cutting assembly at least within the shaft assembly and others position the cutting assembly over the shaft assembly. Various disclosed cutting assemblies are actuated with the handle assembly or the like, which draw the tension members across the blade or vice versa.
