A device for determining a physical parameter of a tissue opening is provided. The device includes an expandable member which is designed for positioning within a tissue opening such as a valve annulus. The expandable member is capable of expanding while applying an inward radial force indicative of a diameter thereof. When the expandable member is positioned within the tissue opening and expanded, an increase in the inward radial force induced by contact between the expandable member and tissue surrounding the opening can be utilized to derive information relating to the physical parameter of the tissue opening.
A device for determining a physical parameter of a tissue opening comprising a catheter having a semi-compliant expandable member including a non-compliant inflatable balloon at least partially covered by an elastic cage configured having a wire mesh, a wire spiral or wire struts, said elastic cage anchored to distal and proximal ends of said balloon, said expandable member being capable of expanding while applying an inward radial force indicative of a diameter thereof, such that when said expandable member is positioned within a tissue opening and expanded, an increase in said inward radial force can be indicative of contact between said expandable member and tissue surrounding the tissue opening.
A method of sizing a tissue opening comprising (a) inflating a semi-compliant expandable member disposed on a catheter within said tissue opening, said expandable member including a non-compliant balloon positioned within an elastic cage anchored to distal and proximal ends of said inflatable balloon;
