Abstract
A positioning tool comprises an elongate positioning member having a first end and a second end, a tubular positioning body coupled to the first end of the elongate positioning member and including a first end, a second end, and an attachment structure disposed within an open center of the positioning body, and a plurality of pairs of alignment apertures, each pair of alignment apertures including a first alignment aperture adjacent to the first end of the positioning body and a second alignment aperture adjacent to the second end of the positioning body.
Claims15
A positioning tool comprising:
- an elongate positioning member having a first end and a second end;
- a tubular positioning body coupled to the first end of the elongate positioning member, the tubular positioning body including a first end, a second end, and an attachment structure disposed within an open center of the positioning body;
- and
- a plurality of pairs of alignment apertures, each pair of alignment apertures including a first alignment aperture adjacent to the first end of the positioning body and a second alignment aperture adjacent to the second end of the positioning body.
A method for positioning a heart valve comprising:
- providing a positioning tool comprising:
- an elongate positioning member;
- a positioning body disposed at an end of the elongate positioning member;
- and
- a plurality of pairs of alignment apertures formed in the positioning body;
- each pair of alignment apertures including spaced apart first and second alignment apertures;
- sliding the positioning body into an aortic sinus region until the second alignment apertures are positioned adjacent to an inflow annulus of the sinus region;
- aligning each of the second alignment apertures with an end of a commissure adjacent to the inflow annulus;
- marking a first commissure location of each of the second alignment apertures;
- retracting the positioning body until the first alignment apertures are substantially coplanar with the inflow annulus and aligned with the marked first commissure locations;
- and
- marking a second commissure location of each of the second alignment apertures.
