Abstract: An assembly (10) for crimping a frame (56) of an implant (58) comprises a crimping device (20) with a base (22) and a crimping mechanism (24) that defines a crimping aperture (26). A bath (28) having a floor (30), and one or more side-walls (32) extending upward from the floor to a side-wall height defines a receptacle (18) that is shaped to receive a portion of the crimping device. The apparatus has an assembled state in which the portion of the crimping device has been received by the receptacle, the crimping device is held securely by the bath, and the aperture is below the side-wall height. Other embodiments are also described.

Abstract: A delivery tool including a shaft and a proximal capsule and a distal capsule is dimensioned for percutaneous delivery to the heart. An open end of the proximal capsule faces the open end of the distal capsule. The capsules are coupled to the shaft in a manner that allows axial movement of the capsule with respect to the shaft. A prosthetic heart valve includes a tubular portion that defines a lumen and prosthetic leaflets disposed within the lumen. The prosthetic heart valve is restrainable in a compressed state by the delivery tool, such that a downstream end of the tubular portion is disposed within the distal capsule. The distal capsule is shaped so as to define an opening for visualizing ensheathing of at least a portion of the downstream end of the tubular portion within the distal capsule. Other embodiments are also described.

Abstract: A delivery tool includes a nosepiece that is fixed to a shaft, and distal to an implant, and an expandable element proximal to the nosepiece. Maximally-expanded, the expandable element (i) has an expanded external diameter at its widest part that is smaller than the expanded internal diameter of a lumen of the frame of the implant, (ii) tapers proximally away from the widest part and from the nosepiece, and (iii) is dimensioned to slide proximally through the lumen of the implant in its expanded state, between leaflets of the implant, and out of the lumen. When non-expanded, the widest part of the expandable element has a non-expanded external diameter that is smaller than the expanded external diameter of the expandable element. In a compressed state of the implant a portion of the expandable element is disposed within the lumen of the frame. Other applications are also described.
