Patent number: 11812970Abstract: A delivery tool includes a tubular distal tip fixed to a distal end of a delivery tube. A retention portion of an implant wire of an implant is removably disposed within the tubular distal tip. A pull wire has a distal end portion that is shaped so as to define a pull-wire loop and is removably disposed partially within the delivery tube. A safety wire is removably disposed partially within the tubular distal tip, with a distal portion of the safety wire passing through a tip distal opening. The safety wire has a proximal end portion that is shaped so as to define a safety-wire hook hooked on the pull-wire loop. Proximal pulling on the pull wire proximally retracts the safety wire from the tip distal opening, thereby allowing the retention portion to pass through the tubular distal tip. Other embodiments are also described.Type: GrantFiled: January 16, 2020Date of Patent: November 14, 2023Assignee: ENDOSTREAM MEDICAL LTD.Inventors: Danel Mayer, Alon May
