Adjustable sizing apparatus
First Claim
1. A system for sizing tissue annulus, the system comprising:
- an elongated support member having a proximal end, a distal end and a passageway extending from the proximal end to the distal end;
an operator actuated movable member joined to the proximal end of the elongated support member for providing fluid through the passageway to the distal end;
an expandable member mounted to the distal end of the elongated support member and receiving the fluid, the expandable member having a reference axis and a substantially continuous outer curved surface disposed about the reference axis and selectively positionable in response to fluid provided by the operator actuated movable member between an inner position proximate the reference axis and an outer position spaced apart from the reference axis; and
means for determining a dimension of the outer curved surface.

Abstract
The present invention is a single apparatus that can be adjusted through a range of diameters to measure an anatomical tissue annulus. The apparatus includes an elongated support member having a proximal end and a distal end. An operator actuated movable member is joined to the proximal end of the elongated support member while an adjustable member is joined to the distal end of the elongated support member. The adjustable member has a reference axis and an outer curved surface selectively positionable in response to the operator actuated member. In particular, the outer curved surface can be selectively positioned between an inner position proximate the reference axis and an outer position spaced apart from the reference axis.
