ANNULOPLASTY SIZERS FOR MINIMALLY INVASIVE PROCEDURES
First Claim
1. A method of sizing a native valve annulus during a minimally invasive mitral valve repair or replacement procedure comprising:
- creating a surgical access port in an intercostals space in a patient'"'"'s body;
exposing the native valve annulus;
inserting a first sizing plate through the surgical access port, the first sizing plate including;
an upper surface and a lower surface defining a thickness of the sizing plate;
first and second keyways extending through the sizing plate from the upper planar surface to the lower planar surface of the sizing plate; and
a bridge member between the first and second keyways configured to be engaged by a laparoscopic grasping tool;
engaging the bridge of the sizing plate using a laparoscopic grasping tool inserted through the surgical access port;
positioning the sizing plate in the valve annulus;
comparing the major and minor dimensions and the shape of the sizing plate to a major and a minor dimension and shape of an anterior leaflet of the mitral valve; and
determining the major and minor dimensions and 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.
