Patent number: 10639181Abstract: A system for delivering an implant including a handle, a trigger, an actuation assembly, and a catheter assembly. The actuation assembly is configured to displace the outer tubular member in the proximal direction and to separately move the inner shaft member distally upon deployment of the trigger from the first position to the second position, and move the inner shaft member proximally with no displacement of the outer tubular member upon return of the trigger from the second position to the first position. The catheter assembly includes an outer tubular member, an inner shaft member, and a pusher assembly.Type: GrantFiled: December 7, 2017Date of Patent: May 5, 2020Assignee: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Daniel H. Shumer, Ronald G. Earles, Nianjiong J. Bei, Barbara Stamberg, Daniel Simon, Maria Del Rosario Nava, Michael L. Green, Matthew J. Gillick

Patent number: 10327932Abstract: Catheter including a pressure chamber defined by proximal and distal seals and inner and outer tubular members. An actuator member, moveable between first and second positions, is disposed within the pressure chamber. Fluid introduced into the pressure chamber applies a force on the actuator member to move the actuator member toward the second position. A lock mechanism, disposed between inner and outer tubular members, includes a latch having an engaged condition preventing movement of the outer tubular member relative the inner member and a disengaged condition allowing movement the outer member. The latch is shifted to the disengaged condition when the actuator member is moved to the second position. With the actuator member in the second position and the latch in the disengaged condition, fluid introduced through the fluid flow port and into the pressure chamber applies a force on the proximal seal to urge the outer tubular member proximally.Type: GrantFiled: February 5, 2016Date of Patent: June 25, 2019Assignee: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Daniel H.
