Annuloplasty sizers for minimally invasive procedures
First Claim
1. A method of sizing a native valve annulus of a mitral valve during a minimally invasive mitral valve repair or replacement procedure comprising:
- creating a surgical access port in an intercostal space in a patient'"'"'s body;
exposing the native valve annulus;
providing a first sizing plate, the first sizing plate including;
an upper planar surface and a lower planar surface defining a thickness of the first sizing plate;
first and second keyways extending through the first sizing plate from the upper planar surface to the lower planar surface of the first sizing plate;
an aperture extending through the upper and lower planar surfaces disposed near a lower edge of the first sizing plate for accommodating a suture threaded through the aperture; and
a bridge member between the first and second keyways configured to be engaged by a laparoscopic grasping tool;
inserting the suture through the aperture in the first sizing plate and using the suture to lower the first sizing plate into the surgical access port;
engaging the bridge member of the first sizing plate using the laparoscopic grasping tool inserted through the surgical access port;
positioning the first sizing plate in the native valve annulus;
comparing a major dimension and a minor dimension and a shape of the first sizing plate to a major dimension and a minor dimension and a shape of an anterior leaflet of the mitral valve; and
determining the major and minor dimensions and the shape of the anterior leaflet of the mitral valve.

Abstract
A sizing plate for sizing a native valve annulus in a patient'"'"'s heart for either valve replacement or repair during a minimally invasive surgical procedure is shown and described. The sizing plate is generally shaped such that it corresponds to the shape of the native valve annulus. Additionally, a thickness of the sizing plate is such that it can be inserted through a space between the ribs of the patient during the procedure. The sizing plate includes two keyways extending though the plate separated by a bridge. The keyways are sized and shaped such that they are adapted to be engaged by a minimally invasive surgical tool such as a laparoscopic grasper. The keyways in conjunction with the bridge facilitate manipulation of the sizing plate by the grasper from an external location.
