Grouping prosthetic valve leaflets based on flexibility values

A recently granted patent (Publication Number: US11883293B2) discloses a method for grouping prosthetic valve leaflets using a computer processor. The method involves deriving a leaflet-flexibility value for each leaflet in an aggregate of prosthetic valve leaflets and receiving a group size value to designate leaflets into groups based on similarity in flexibility values. An intra-group tolerance is utilized to ensure the flexibility values within a group do not exceed a maximum allowable difference. The designated leaflet groups are then outputted using indicators in communication with the computer processor.

Furthermore, the method includes assigning indices to leaflet-flexibility values, determining the maximum number of within-tolerance index groups attainable, and storing this maximum number. The process involves iteratively selecting potential index groups based on flexibility values, group differentials, and intra-group tolerance. The goal is to designate leaflets into groups with a cumulative average differential value less than that of within-tolerance index groups. Adjustments to the intra-group tolerance can be made based on previews related to the designated leaflet groups, such as yield or closeness of fit of preliminary leaflet groups. The method also includes grouping the designated leaflets into prosthetic heart valves after the grouping process is completed.

In summary, this patented method offers a systematic approach to grouping prosthetic valve leaflets based on their flexibility values, ensuring that each designated group meets specific criteria for similarity in flexibility. By utilizing computer processing and intra-group tolerance, the method aims to optimize the grouping process to achieve the best possible fit for prosthetic heart valves. Adjustments based on previews allow for fine-tuning of the grouping parameters, ultimately leading to improved outcomes in the creation of prosthetic heart valves.
