Abstract
A sheath for loading and retrieving a prosthetic implant is disclosed, which includes a tube. The tube has opposing distal and proximal ends in its axial direction, and the distal end has a plurality of support rods arranged at intervals in a circumferential direction of the tube and having relative converged and flared configurations. A plurality of connecting strips are provided in the axial direction between two adjacent support rods, and each connecting strip is folded back and forth in the converged configuration and tends to be straightened in the flared configuration relative to the converged configuration. The straightened lengths of the connecting strips increase sequentially from the proximal end to the distal end, and two ends of each connecting strip are connected to the support rods on the corresponding sides and the connecting portions have the same axial level.
