摘要

A suturing member and method of mounting the suturing member on an implantable device, as a heart valve. The suturing member has a porous fabric cover surrounding a semi-rigid plastic core. An annular sleeve of heat shrinkable plastic material is located within the cover to hold the cover in assembled relation with the device in a manner which allows for rotation of the device after the suturing member has been attached to the tissue. In the method of mounting the suturing member on the device, the suturing member is shaped and cured on the device with the use of a mold. The mold is heated to cure the plastic core of the suturing member and bond the core to the inner surface of the cover.
