摘要
A delivery catheter includes a tip, a spindle and a lock mechanism. The tip includes a tapered portion and a tip sleeve. The tip sleeve extends proximally and has a lumen. The spindle includes a plurality of spindle pins. The lock mechanism locks the tip sleeve to the spindle to prevent relative longitudinal movement between the spindle and the tip sleeve. The delivery catheter includes a delivery configuration with the tip sleeve covering the spindle pins and a release configuration with a proximal end of the tip sleeve distal of the spindle pins. The lock mechanism locks the prosthesis delivery system in the release configuration. Each spindle pin of the plurality of spindle pins includes a smooth, curved profile.
