  • Publication number: 20170325939
    Abstract: The present subject matter describes a suturing rings and method of manufacture of suturing rings for prosthetic heart valves. A plurality of suture holes are formed along a length of the metal sheet by performing punching or similar operations. The metal sheet has a substantially constant thickness throughout the length of the metal sheet. The rectangular metal sheet is rolled along the length until two ends of the metal sheet abut with each other. The two ends of the metal sheet are welded to form a metallic tube. The metallic tube is reshaping using a forming tool to obtain a suturing ring having an inner surface with a substantially convex profile. The suturing ring has an inner diameter at an inner peripheral edge at a first open end and an inner diameter at an inner peripheral edge at a second open end greater than an inner diameter at a mid-circumferential plane.
