Abstract

A reusable surgical device for holding a stentless valve during implantation. The surgical device has a generally cylindrical body mountable on a disposable, elongated handle. The generally cylindrical body defines a reduced diameter at one end for receiving the stentless valve thereon and permitting maneuvering space during suturing. A plurality of radial marking lines spaced approximately 120.degree. apart indicated suture placement. Annular ridges form a groove permitting the stentless valve to be secured in place by a pressure-exerting fastener such as a tie wrap. The cylindrical body is inserted through the stentless valve with the marking lines oriented in predetermined relation to the valve leaflets until the stentless valve is properly positioned on the body, and the disposable handle is attached to the body.
