Publication number: 20230157692Abstract: The present disclosure relates to a fastener applicator including a handle, a first trigger coupled rotatably with respect to the handle, and a second trigger coupled rotatably with respect to the handle. An interlock is disposed with the second trigger and comprises a cam follower engaged in a cam channel that selectively prevents rotation of the second trigger relative to the first trigger depending on a location of the cam follower within the cam channel. The location of the cam follower in the cam channel is set by a position of the first trigger. Methods of operating the various embodiments disclosed are also provided.Type: ApplicationFiled: January 24, 2023Publication date: May 25, 2023Applicant: DATASCOPE CORP.Inventors: William K.
