  • Publication number: 20240074854
    Abstract: Fixation system for engaging tissue of a patient including an implantable fixation device having a first arm and a second arm, a first proximal element, a second proximal element, and a coupling member. The system includes a delivery device having a catheter, a shaft extending through the at least one lumen of the catheter, a first proximal element actuator and a second proximal element actuator. The second end portions of the first proximal element actuator and second proximal element actuator can be coupled to at least one of the shaft and the coupling member.

  • Publication number: 20230329867
    Abstract: Medical device delivery system including a catheter, handle, lock line handle, and lock line. The catheter includes a proximal end portion and a distal end portion. The handle is coupled to the proximal end portion of the catheter. The lock line handle is releasably coupled to the handle and actuatable between a lock position and an unlock position. The lock line includes a first end portion fixedly coupled to the lock line handle, a second end portion releasably coupled to the lock line handle, and an intermediate portion configured to be releasably coupled to the medical implant disposed proximate the distal end portion of the catheter. Actuating the lock line handle from the lock position toward the unlock position increases tension on the lock line, and actuating the lock line handle from the unlock position toward the lock position decreases tension on the lock line.

  • Publication number: 20210015614
    Abstract: Fixation system for fixation of leaflets of a heart valve including an implantable fixation device having a first arm and a second arm, a first proximal element moveable relative to the first arm between a first position and a second position, and a second proximal element moveable relative to the second arm between a first position and a second position. The fixation system includes a delivery device having a catheter, a first proximal element line and a second proximal element line, and a handle having a first and second proximal element line handles coupled to the first proximal element line and the second proximal element line, respectively. The handle can include an interlock moveable between an unlocked position and a locked position.
