摘要:
Systems and methods for providing transapical access to a heart chamber for performing an intra cardiac procedure are described. The systems include a helical needle driver and a dilator. The helical needle driver rotates and translates a shuttle member which advances one or more helical needles to place a helical suture within the myocardium. After removing the needles, the dilator is advanced through the pre-placed helical suture, dilating both a passage and the circumscribing suture. After performing procedure, the pre-placed suture may be closed by proximally retracting an external end of the suture.
