摘要： A prosthetic valve is advanced to a heart of a subject while the prosthetic valve is in a compressed state thereof, the prosthetic valve including a plurality of snares coupled to a tubular valve body. The prosthetic valve is positioned within the heart such that the plurality of snares is disposed upstream of the leaflets, and the plurality of snares is expanded upstream of the leaflets. Subsequently the prosthetic valve is moved in a downstream direction such that the plurality of snares is disposed downstream of the leaflets. Subsequently, the prosthetic valve is secured at the native valve while the plurality of snares remains disposed downstream of the leaflets.

摘要： A rod (508) is transfemorally advanceable to the heart. An implant (460) comprises (i) a first frame (462), compressed around a first longitudinal site of a distal portion of the rod, (ii) a second frame (464), compressed around a third longitudinal site of the distal portion, (iii) a valve member (50), disposed within the second frame, and (iv) a flexible sheet (466), coupling the first frame to the second frame, and disposed around a second longitudinal site of the distal portion, the second longitudinal site being between the first longitudinal site and the third longitudinal site. An extracorporeal controller (569) is coupled to a proximal portion of the rod, and is operably coupled to the distal portion of the rod. Operating the controller bends the distal portion of the rod causing articulation between the frames. Other embodiments are also described.

摘要： A tool (410) for use with an implant (20) includes a housing (426) and a controller (440). The housing includes a tubular wall (428) that circumscribes a longitudinal axis; is dimensioned to house at least part of the implant; and defines a track (430) that follows a generally-helical path around the longitudinal axis. The controller includes a rod (442) that extends from a proximal part of the tool to the housing; and an actuator (444). The actuator is fixedly coupled to the rod, includes an engaging element (446) that engages the track, and is rotatable with respect to the housing. The controller and the housing mechanically cooperate such that rotation of the actuator with respect to the housing slides the housing longitudinally with respect to the actuator. Other embodiments are also described.

摘要： A tool is configured for transluminal delivery of an implant. The tool has a proximal part and a distal part, and comprises a shaft, a nosepiece, a sheath, and a balloon. The nosepiece is fixed to the shaft, and is arranged with respect to the implant such that the implant extends proximally away from the nosepiece and over the shaft. The sheath houses the implant. The balloon is disposed at the distal part of the tool, and is in fluid communication with the proximal part of the tool. When maximally inflated, the balloon has (i) a widest part that has an inflated diameter that is less than the diameter of the sheath or at most 10 percent greater than the diameter of the sheath, and (ii) a tapered portion that tapers longitudinally away from the widest part and from the nosepiece.
