Heart valve sizing ring and method
View Patent ↗A device for measuring heart valve for sizing a heart valve reinforcement ring, includes a first handle having a first shaft an outer ring coupled to the first shaft, wherein the outer ring has an inner surface; and an inner ring having an outer surface, wherein the inner ring is removably couplable to the outer ring. The inner surface of the outer ring and the outer surface of the inner ring further have reciprocal mating surfaces configured and arranged to grip sutures therebetween when coupled together. The device may further have a second handle with a second shaft connected to the inner ring. Alternatively, the first handle may have a second shaft that is connected to a second outer ring.
1. A device for measuring heart valve for sizing a heart valve reinforcement ring, comprising:
a first handle having a first shaft;
an outer ring coupled to the first shaft, the outer ring having an inner surface; and
