1. A prosthesis for positioning within an annulus of a heart valve, the prosthesis comprising:
- a leaflet contacting member having an outer surface, an inflow side, an outflow side, and an aperture that extends through at least a portion of the leaflet contacting member, the aperture being sized to allow one or more wires to extend through the leaflet contacting member from the inflow side to the outflow side; and
an anchoring member coupled to the leaflet contacting member, the anchoring member configured to anchor the leaflet contacting member within the annulus of a heart valve,wherein the outer surface is configured to contact one or more leaflets of the heart valve during coaptation of the leaflets, and the contact of the leaflets with the outer surface prevents the leaflets from contacting the one or more wires when positioned to extend through the aperture of the leaflet contacting member.

Abstract
A prosthesis can include a leaflet contacting member and an anchoring member. The leaflet contacting member can have an outer surface and an aperture that extends through at least a portion of the leaflet contacting member. The outer surface of the leaflet contacting member can be configured to contact one or more leaflets of the heart valve during coaptation of the leaflets, and the contact of the leaflets with the outer surface can prevent the leaflets from contacting one or more wires that extend through the aperture of the leaflet contacting member.

12. A system for preventing contact between a wire and one or more valve leaflets, the system comprising:
-
a prosthetic device comprising a main body that is sized for placement at least partially between two valve leaflets that are movable between an open state and a closed state, the main body comprising an opening that extends from a first side of the main body to a second side of the main body; and at least one wire configured to extend through the opening of the main body from the first side to the second side, wherein the opening is spaced apart from an outer perimeter of the main body so that, when the prosthetic device is placed between the two valve leaflets, the wire does not contact either of the two valve leaflets when the valve leaflets are in the open or closed states. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method for delivering a wire through a valve of the heart, the method comprising:
-
providing a leaflet contacting member having an outer surface and an aperture passing through the leaflet contacting member; positioning the leaflet contacting member at least partially between two leaflets of a valve so that the outer surface of the leaflet contacting member contacts the leaflets when the leaflets undergo coaptation; and passing one or more wires through the aperture of the leaflet contact member, the aperture being positioned such that the one or more wires do not contact the leaflets. - View Dependent Claims (20, 21)

22. A diagnostic tool comprising:
-
an elongate member having a proximal portion, a distal portion, and a distal opening, the elongate member having a lumen that extends from the proximal portion to the distal portion; a temporary coaptation member coupled to the distal portion of the elongate member at an attachment portion, the temporary coaptation member being configured to be positioned between two leaflets, wherein the attachment portion is located proximally to the distal opening in the elongate member, the distal opening being in fluid connection with the lumen. - View Dependent Claims (23, 24)

25. A method of using a diagnostic tool for determining an effectiveness of an temporary coaptation member to minimize regurgitation in a heart valve in a body of a patient;
- the method comprising;
providing an elongate member having a proximal portion and a distal portion; providing an temporary coaptation member coupled to the distal portion of the elongate member; positioning the temporary coaptation member at least partially between two leaflets of heart valve, the leaflets being movable between an open state and a closed state; monitoring the effectiveness of the temporary coaptation member in restricting blood flow between the leaflets and the temporary coaptation member when the leaflets are in the closed state; and removing the expandable member from the patient'"'"'s body. - View Dependent Claims (26, 27, 28)
