Abstract
An implantable annuloplasty suture guide is intended to lie against at least a portion of an annulus surrounding a human heart. The implantable annuloplasty suture guide is made of an elongated ribbon of braided, heat setable material. The braided, heat-setable material is heat-set in a curved lengthwise configuration corresponding to at least a portion of the annulus of the human heart valve. A method of making an implantable annuloplasty suture guide configured to lie against at least a portion of an annulus defined by tissue surrounding a human heart. The method includes the steps of providing an elongate biocompatible ribbon comprising a braided, heat setable material. A fixture is provided, with the fixture comprising a heat conducting material defining an elongate cavity having a curved length-wise configuration corresponding to at least a portion of the annulus defined by the tissue surrounding the human heart. The elongate biocompatible ribbon is placed in the cavity and the fixture is heated to provide a select temperature for a select time in the cavity, the select temperature and the select time being sufficient to heat-set the elongate biocompatible ribbon in the curved…
