Abstract: An introducer sheath assembly includes an expandable introducer sheath including an expandable braid defining an elongate tubular member moveable between a collapsed configuration for delivery and an expanded configuration for deployment, the expandable braid having a first length when in the collapsed configuration and a second, reduced, length when in the expanded configuration. The introducer sheath assembly includes a dilator adapted to releasably hold the expandable introducer sheath in its collapsed configuration for delivery until the dilator is actuated to release the expandable braid from the dilator, thereby permitting the expandable braid to expand to its expanded configuration.

Abstract: An implantable medical device adapted to be implanted at an implantation site may be capable of being implanted in more than one rotational orientation at the implantation site. The implantable medical device includes an expandable body that is adapted to expand from a collapsed configuration for delivery to an expanded configuration for deployment, and a radiopaque indicator that is disposed relative to the expandable body. The radiopaque indicator is adapted to be have a first appearance if viewed in a first rotational orientation and a second, different appearance if viewed in a second rotational orientation that is different from the first rotational orientation. As an example, the implantable medical device may be a catheter-delivered replacement aortic valve.
