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: Example medical device loading devices are disclosed. An example loading device for a stent-valve includes an elongated body having a proximal end region, a distal end region and a lumen extending therein. The loading device also includes a collar coupled to the distal end region of the body, the collar including first end region, a second end region and a lumen extending therein. Further, the loading device includes a first compression assembly coupled to the collar, wherein the first compression assembly is configured to shift between a first position a second position. The loading device also includes a second compression assembly coupled to the collar, wherein the second compression assembly is configured to shift between a third position and a fourth position.
