Abstract: An implant delivery system for delivering a replacement heart valve implant to a native heart valve may include an elongate shaft assembly including an implant holding portion configured to constrain a replacement heart valve implant in a radially collapsed configuration. The elongate shaft assembly may include a plurality of longitudinal marker elements configured to be visible under fluoroscopy with an imaging device. The plurality of longitudinal marker elements is configured to rotationally align commissure posts of the replacement heart valve implant with native valve commissures of the native heart valve under fluoroscopy with the imaging device when the replacement heart valve implant is shifted to a radially expanded configuration within the native heart valve.

Abstract: A pigtail catheter may include an elongate shaft having a curled distal tip, a tubular sheath slidably disposed over the elongate shaft, and a compliant expandable member fixed to the elongate shaft and the tubular sheath. A transcatheter aortic valve replacement (TAVR) system may include the pigtail catheter, a TAVR delivery device comprising an elongate shaft having an implant holding portion proximate a distal end thereof, and a TAVR implant disposed within the holding portion in a collapsed configuration, the TAVR implant comprising an expandable framework including a lower crown disposed at an upstream end and an upper crown disposed downstream of 10 the lower crown. The compliant expandable member is configured to identify a downstream extent of a surgical aortic valve implant disposed within an ascending aorta prior to deploying the TAVR implant.

Abstract: A replacement heart valve implant includes an expandable framework configured to shift between radially collapsed and radially expanded configurations, and a plurality of valve leaflets secured to the framework. The framework includes a tubular wall defining inflow and outflow ends. The inflow end includes an attachment tab extending radially inward from the tubular wall. A replacement heart valve system includes the implant and a delivery system including a shaft assembly extending distally from a handle. A method of loading the implant includes positioning the implant adjacent an implant holding portion of the delivery system in the collapsed configuration; positioning a distal sheath of the delivery system at least partially over a groove formed in an outer surface of a stent holder of the delivery system; inserting the attachment tab into the groove; and rotating the implant relative to the delivery system.
