Abstract: A steerable delivery system is provided for delivering a replacement heart valve to a native heart valve location. The steerable delivery system includes an outer sheath assembly having a capsule along a distal end portion for retaining the replacement heart valve in a compressed configuration. The capsule is constructed to provide both compression resistance and flexibility. The capsule may be formed with an outer polymer layer, a metal middle layer located on a radially inner surface of the outer polymer layer, and an inner liner located on a radially inner surface of the metal middle layer. A fluoroelastomer layer is provided for bonding the inner liner to the metal middle layer. The metal middle layer is preferably a metal hypotube.

Abstract: A simple light weight bow sight mounting apparatus which has a rigid frame slidably mountable on a bow frame for movement along a first linear path corresponding in direction generally to the archers line of sight. A threaded rod is mounted on the frame for rotation about the longitudinal axis of the rod and carries thereon a slide bock that is moved along a second linear path by rotating the threaded rod. A sight mounting block is mounted on the slide block for rotation about an axis parallel to the first linear path. A sight element is mountable on the slide block and adjustably movable along a third linear path. The first, second and third linear paths are mutually perpendicular.
