A delivery system for delivering an implantable intravascular device to a targeted cardiac valve, the delivery system comprising: a handle assembly ; 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 an intravascular device, the delivery member further including: an outer sheath having a distal piece proximal to an atraumatic distal tip of the delivery member , the distal piece being configured to house the intravascular device in a pre-deployed configuration; a steering component configured to curve the delivery member in a compound curve that enables intravascular delivery of the delivery member to the targeted cardiac valve; a delivery catheter configured to longitudinally translate the intravascular device relative to the outer sheath ; a suture catheter having one or more tethers configured to detachably couple to the intravascular device, the suture catheter being longitudinally translatable relative to the delivery catheter to enable adjustment of tension in the one or more tethers; and a guidewire tube extending through the delivery member to the distal end of the delivery member where it is attached to the distal tip , the guidewire tube being linearly translatable relative to the suture catheter ; the suture catheter is disposed within the delivery catheter , and the guidewire tube is disposed within the suture catheter . a handle assembly ; 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 an intravascular device, the delivery member further including: an outer sheath having a distal piece proximal to an atraumatic distal tip of the delivery member , the distal piece being configured to house the intravascular device in a pre-deployed configuration; a steering component configured to curve the delivery member in a compound curve that enables intravascular delivery of the delivery member to the targeted cardiac valve; a delivery catheter configured to longitudinally translate the intravascular device relative to the outer sheath ; a suture catheter having one or more tethers configured to detachably couple to the intravascular device, the suture catheter being longitudinally translatable relative to the delivery catheter to enable adjustment of tension in the one or more tethers; and a guidewire tube extending through the delivery member to the distal end of the delivery member where it is attached to the distal tip , the guidewire tube being linearly translatable relative to the suture catheter ; the suture catheter is disposed within the delivery catheter , and the guidewire tube is disposed within the suture catheter . an outer sheath having a distal piece proximal to an atraumatic distal tip of the delivery member , the distal piece being configured to house the intravascular device in a pre-deployed configuration; a steering component configured to curve the delivery member in a compound curve that enables intravascular delivery of the delivery member to the targeted cardiac valve; a delivery catheter configured to longitudinally translate the intravascular device relative to the outer sheath ; a suture catheter having one or more tethers configured to detachably couple to the intravascular device, the suture catheter being longitudinally translatable relative to the delivery catheter to enable adjustment of tension in the one or more tethers; and a guidewire tube extending through the delivery member to the distal end of the delivery member where it is attached to the distal tip , the guidewire tube being linearly translatable relative to the suture catheter ; the suture catheter is disposed within the delivery catheter , and the guidewire tube is disposed within the suture catheter . <EOS>
