Abstract: A system for delivering a replacement heart valve implant may include the implant including an expandable framework and leaflets coupled to the framework, and a delivery device including a handle and an elongate catheter extending from the handle. The catheter includes an outer sheath and an inner shaft movably disposed within the outer sheath. The implant is releasably coupled to the inner shaft. The inner shaft includes an orientation lumen extending longitudinally within the inner shaft, the orientation lumen being offset from a central guidewire lumen of the inner shaft. The delivery device includes an orientation mandrel disposed within the orientation lumen, the orientation mandrel extending distally from the handle to a distal end proximate a closed distal end of the orientation lumen. The orientation mandrel is operably coupled to an orientation mechanism of the handle configured to apply compressive force or tensile force to the orientation mandrel.

Abstract: A replacement heart valve system may include a replacement heart valve implant comprising an expandable framework configured to shift from a radially collapsed configuration to a radially expanded configuration, and a plurality of valve leaflets disposed within and secured to the framework, and an implant delivery system comprising a handle assembly and an elongate shaft assembly extending distally from the handle assembly. The elongate shaft assembly may include an inner shaft axially secured to the handle assembly, an outer tubular member axially secured to the handle assembly and disposed about the inner shaft, and an implant holding portion. The implant holding portion is configured to constrain the implant in the radially collapsed configuration when the implant holding portion is disposed in a delivery configuration, wherein the implant holding portion is rotatable relative to the outer tubular member.
