Abstract
A device for measuring an internal dimension of a native cardiac valve annulus includes an elongated support member having a proximal portion and a distal portion. A measuring portion is coupled to the distal portion, and an indicator is coupled to the proximal portion of the support member. The measuring portion is biased towards a deployed configuration such that when deployed it applies an outwardly directed radial force to the native valve annulus.
Claims19
A device for measuring an internal dimension of a native cardiac valve annulus, the device comprising:
- an elongated support member having a proximal portion and a distal portion, the distal portion including an end having a bore and a longitudinal slot;
- a measuring band having a first end and a second end, the first end disposed within the bore and the second end coupled to the distal portion;
- a shaft extending through the support member, the shaft having a distal end coupled to the first end of the measuring band and a proximal end;
- and
- an indicator coupled to the proximal end of the shaft, the indicator adapted to provide an indication of the internal dimension;
- wherein the measuring band has a contracted configuration in which the band is at least partially wound about a transverse axis and an expanded configuration in which the band is substantially unwound.
