Delivery systems for replacement heart valves

A delivery system for delivering an expandable implant to a body location, the delivery system comprising:

• a shaft assembly comprising a proximal end portion and a distal end portion, wherein the proximal end portion of the shaft assembly comprises a handle including at least one actuator;
• a plurality of suture portions,
• wherein a first end of each of the plurality of suture portions is permanently coupled to the distal end portion of the shaft assembly,
• wherein a second end of each of the plurality of suture portions is removably coupled to at least one retention member of the distal end portion of the shaft assembly after being inserted through a coupling member of an implant,
• wherein actuation of the at least one actuator causes the second end of each of the plurality of suture portions to be decoupled from the at least one retention member of the distal end portion of the shaft assembly.

A delivery system for delivering an expandable implant to a body location, the delivery system comprising:

• an outer shaft comprising a proximal end and a distal end;
• an inner manifold shaft comprising a proximal end and a distal end, wherein the manifold shaft is coaxially positioned within the outer shaft, wherein the inner manifold shaft comprises a distal tether retention component at the distal end of the manifold shaft;
• nine suture loops, wherein each of the nine suture loops comprise a first end opposite a loop end, wherein the first end is non-removably coupled to the distal tether retention component;
• and
• a release suture configured to releasably secure the nine suture loops to the inner manifold shaft;
• wherein the loop end of each of the nine suture loops is looped through a respective eyelet positioned at a proximal end of a replacement heart valve,
• wherein each loop end of the nine suture loops is configured to receive the release suture, and
• wherein removing the release suture from the loop end of the nine suture loops allows the suture loops to be released from the respective eyelets, thereby allowing the replacement heart valve to be decoupled from the delivery device.
