摘要： A delivery system is provided for delivering an expandable medical device. The delivery system includes a catheter shaft, a proximal stop coupled to the catheter shaft, an inner tube coupled to the proximal stop and extending distally therefrom, a distal stop coupled to the inner tube, and a balloon disposed over the distal stop, the inner tube, and the proximal stop. The inner tube defines an inflation lumen and has a plurality of openings extending through a sidewall of the inner tube into the inflation lumen. The distal stop includes at least one channel extending through a sidewall of the distal stop into the lumen. The distal stop is configured to allow inflation fluid to flow through the inner tube and the at least one channel into a distal region of the balloon.

摘要： An implantable medical device is adapted to be implanted at an implantation site within the vasculature and is capable of being implanted at the implantation site within the vasculature at more than one position relative to the implantation site. This may include a relative axial position and/or a relative rotational position. The implantable medical device includes an expandable frame that is adapted to expand from a collapsed configuration for delivery to an expanded configuration for deployment, and one or more radiopaque markers disposed relative to the expandable frame such that fluoroscopic imaging of the implantable medical device during deployment provides an indication of a position of the implantable medical device relative to the implantation site. The implantable medical device may be a replacement cardiac valve such as a replacement aortic valve, for example.
