A delivery system for intravascularly delivering a replacement heart valve to a targeted cardiac valve, the delivery system comprising: an expandable replacement heart valve; a handle assembly; and an elongated delivery member coupled to the handle assembly and extending distally from the handle assembly, the delivery member having a distal end and being configured to detachably couple to the expandable replacement heart valve at the distal end, the delivery member further including: an outer sheath having a valve cover configured to constrain the expandable replacement heart valve in a compressed configuration; a steering component configured to steer the delivery member to enable intravascular delivery of the delivery member to the targeted cardiac valve; a delivery catheter configured to longitudinally translate the expandable replacement heart valve relative to the outer sheath, the delivery catheter including a distal can (610, 79) configured in size and shape to constrain a proximal section of the expandable replacement heart valve when the expandable replacement heart valve is held in the compressed configuration, the distal can (610, 79) thereby relieving expansion pressure against an inner surface of the valve cover, the distal can (610, 79) also providing a counterforce to maintain the expandable replacement heart valve in position when the outer sheath is retracted; and a suture catheter having one or more tethers configured to detachably couple to a proximal section of the expandable replacement heart valve, the suture catheter being longitudinally translatable relative to the delivery catheter to enable adjustment of tension in the one or more tethers. an expandable replacement heart valve; a handle assembly; and an elongated delivery member coupled to the handle assembly and extending distally from the handle assembly, the delivery member having a distal end and being configured to detachably couple to the expandable replacement heart valve at the distal end, the delivery member further including: an outer sheath having a valve cover configured to constrain the expandable replacement heart valve in a compressed configuration; a steering component configured to steer the delivery member to enable intravascular delivery of the delivery member to the targeted cardiac valve; a delivery catheter configured to longitudinally translate the expandable replacement heart valve relative to the outer sheath, the delivery catheter including a distal can (610, 79) configured in size and shape to constrain a proximal section of the expandable replacement heart valve when the expandable replacement heart valve is held in the compressed configuration, the distal can (610, 79) thereby relieving expansion pressure against an inner surface of the valve cover, the distal can (610, 79) also providing a counterforce to maintain the expandable replacement heart valve in position when the outer sheath is retracted; and a suture catheter having one or more tethers configured to detachably couple to a proximal section of the expandable replacement heart valve, the suture catheter being longitudinally translatable relative to the delivery catheter to enable adjustment of tension in the one or more tethers. an outer sheath having a valve cover configured to constrain the expandable replacement heart valve in a compressed configuration; a steering component configured to steer the delivery member to enable intravascular delivery of the delivery member to the targeted cardiac valve; a delivery catheter configured to longitudinally translate the expandable replacement heart valve relative to the outer sheath, the delivery catheter including a distal can (610, 79) configured in size and shape to constrain a proximal section of the expandable replacement heart valve when the expandable replacement heart valve is held in the compressed configuration, the distal can (610, 79) thereby relieving expansion pressure against an inner surface of the valve cover, the distal can (610, 79) also providing a counterforce to maintain the expandable replacement heart valve in position when the outer sheath is retracted; and a suture catheter having one or more tethers configured to detachably couple to a proximal section of the expandable replacement heart valve, the suture catheter being longitudinally translatable relative to the delivery catheter to enable adjustment of tension in the one or more tethers.
