Replacement heart valve commissure assembly

A replacement heart valve implant, comprising:

• an expandable anchor member actuatable between a delivery configuration and a deployed configuration;
• and
• a replacement heart valve commissure assembly comprising:
• a locking mechanism including a first locking portion spaced apart from a second locking portion in a delivery configuration, wherein the first locking portion is configured to engage with the second locking portion in a deployed configuration, and the first locking portion is longitudinally actuatable relative to the second locking portion between the delivery configuration and the deployed configuration;
• a first valve leaflet secured to the first locking portion;
• and
• a second valve leaflet secured to the first locking portion;
• wherein a first sleeve portion of the first valve leaflet is fixedly attached to a first fabric sleeve wrapped around a first leg of the first locking portion by a first filament, and a second sleeve portion of the second valve leaflet is fixedly attached to a second fabric sleeve wrapped around a second leg of the first locking portion by a second filament
• wherein the locking mechanism is configured to lock the expandable anchor member in the deployed configuration.

A method of assembling a replacement heart valve commissure assembly for use in a replacement heart valve implant, comprising:

• inserting a first sleeve portion of a first valve leaflet and a second sleeve portion of a second valve leaflet through a longitudinally-oriented tissue slot of a first locking portion of a locking mechanism, the locking mechanism comprising the first locking portion and a second locking portion, wherein the first locking portion is longitudinally actuatable relative to the second locking portion to selectively engage the first locking portion with the second locking portion;
• inserting a first fabric sleeve through the longitudinally-oriented tissue slot between the first sleeve portion of the first valve leaflet and a first leg of the first locking portion, and inserting a second fabric sleeve through the longitudinally-oriented tissue slot between the second sleeve portion of the second valve leaflet and a second leg of the first locking portion;
• wrapping the first fabric sleeve around the first leg of the first locking portion such that the first fabric sleeve overlaps itself adjacent the first sleeve portion of the first valve leaflet to form a first overlapped portion, and wrapping the second fabric sleeve around the second leg of the first locking portion such that the second fabric sleeve overlaps itself adjacent the second sleeve portion of the second valve leaflet to form a second overlapped portion;
• and
• fixedly attaching the first overlapped portion of the first fabric sleeve to the first sleeve portion of the first valve leaflet, and fixedly attaching the second overlapped portion of the second fabric sleeve to the second sleeve portion of the second valve leaflet.
