1. A device for repairing a valve leaflet in a beating heart of a patient, comprising:

  • a handle assembly including a shaft extending from a distal end of the handle and adapted to be extended into a chest cavity of the patient, the shaft including a suture channel extending longitudinally through the shaft adapted to receive a suture and a needle channel extending longitudinally through the shaft generally axially parallel with the suture channel;

    a capture assembly extending from a distal portion of the shaft and adapted to be positioned within the beating heart, the capture assembly having a clamping mechanism including a proximal clamping jaw defining a distally facing clamping surface and a distal clamping jaw movable with respect to the proximal clamping jaw and defining a proximally facing clamping surface; and

    a needle adapted to be slidably positioned within the needle channel, the needle channel having a needle opening defined proximate where the needle channel terminates at the distally facing clamping surface defined by the proximal clamping jaw,the distal clamping jaw including a jaw suture channel extending at least partially around the distal clamping jaw, a needle lumen extending into the proximally facing clamping surface and aligned with the needle opening, and a suture groove extending across the needle lumen,such that when a suture is extended through the suture channel of the shaft, around the jaw suture channel of the distal clamping jaw and along the suture groove, the needle can be selectively advanced distally out of the needle opening at the proximal clamping jaw and past the suture positioned in the suture groove into the needle lumen without dislodging the suture from the suture groove and retracted proximally to engage the suture and remove the suture from the suture groove.
