Abstract: A delivery system includes an outer shaft including a capsule at a distal portion thereof configured to restrain a prosthetic device, an inner shaft disposed within the outer shaft, and a capture device disposed between the outer shaft and the inner shaft. The capture device is configured to retain a portion of the prosthetic device. The capture device includes: a body including a central passage, a plurality of radial openings extending from the central passage radially outward to an outer surface of the body, and a plurality of slots in the outer surface of the body; and a plurality of capture loops, each capture loop extending radially outward through a corresponding radial opening, each capture loop configured to extend through a portion of the prosthetic device, and a distal end of each capture loop configured to be releasably restrained in a corresponding slot of the plurality of slots.

Abstract: Aspects of the disclosure provide a delivery device including a handle assembly as well as an inner catheter connected to the handle assembly. The inner catheter has a distal portion configured to receive an implant. The delivery device further includes an outer catheter connected to the handle assembly and coaxially positioned over the inner catheter. The delivery device also includes a capsule assembly including a proximal capsule secured to a distal end of the inner catheter. The capsule assembly also includes a distal capsule connected to a capsule shaft that extends within the inner catheter, the capsule shaft interconnecting the distal capsule to the handle assembly. The capsule assembly includes engagement features to releasably secure the distal capsule to the proximal capsule. Methods of loading and releasing an implant from a delivery device are also disclosed.

Abstract: A heart valve prosthesis includes a frame defining a central lumen, a valve assembly disposed within the central lumen of the frame, and a plurality of gripper pads. The gripper pads are configured to engage lacerated leaflets of a previously implanted heart valve prosthesis. The gripper pads are configured to separate from each other to separate the lacerated leaflets when the heart valve prosthesis radially expands from a radially compressed configuration to a radially expanded configuration.
