ABSTRACT:
An instrument for spreading the anterior leaflet of a mitral valve. The surgical instrument is designed to allow a surgeon to grip an instrument with one hand during sizing of the anterior leaflet prior to implantation of an annuloplasty ring in a heart valve. The instrument includes a pair of tines that each have an engagement tip for engaging the chordae tendinae proximate an anterior leaflet of a heart valve. The tines are coupled together by a gripping mechanism that may be easily held in one hand, while an annuloplasty ring sizer is held in the surgeon's other hand.
