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: Devices, systems and methods are described herein to provide improved steerability for delivering a prosthesis to a body location, for example, for delivering a replacement mitral valve to a native mitral valve location. The steerable delivery system can contain a steerable rail configured for multi-plane bending to direct a distal end of the delivery system.

Abstract: A mobile robot (for example, a robot used for package deliveries, among other purposes) may include a mast with a visual indicator for providing visibility to drivers and pedestrians in the environment proximate to the mobile robot. The mast may produce a large moment arm, which may result in the mast being more likely to break off from the robot. To mitigate or prevent damage to any components of the mast and/or the mobile robot when such a breakage occurs, described herein is an omni directional breakage joint that is used to connect the mast to the mobile robot. The omni directional breakage joint comprises multiple ball and socket joints that provide structural support between the mast and the mobile robot, while simultaneously allowing for a certain movement freedom of the mast and allowing for the mast to easily be engaged and disengaged from the mobile robot without causing damage to any components.

Abstract: A roller assembly for a mobile cleaning system for cleaning a work surface can include a drive shaft, a sheath, a bushing, and a bushing shroud. The drive shaft can be rotatable about a drive axis, and the drive shaft can include a driven end and an opposite bushing end. The sheath can be supported by the drive shaft and the sheath can be rotatable with the drive shaft. The sheath can include a shell engageable with the work surface. The bushing can be located about the bushing end of the drive shaft. The bushing shroud can be connected to the bushing. The sheath and the drive shaft can be together rotatable with respect to the bushing and the bushing shroud, the bushing shroud can include an outer portion defining a first radius of curvature and a recessed portion connected to the outer portion.

Abstract: Devices, systems and methods are described herein to provide improved steerability for delivering a prosthesis to a body location, for example, for delivering a replacement mitral valve to a native mitral valve location. A delivery component can have a plurality of slots that provide for desired bending of the delivery component, particularly compound bending of the delivery component that can facilitate steering of the delivery component in three dimensions.

Abstract: An autonomous mobile robot includes a flexible member including a polymer layer extending along an entire length of the flexible member, and an end portion vertically movable away from a body of the robot. A first portion of a fastening mechanism extends along a first lateral edge of the polymer layer and a second portion of the fastening mechanism extends along a second lateral edge of the polymer layer. The first portion of the fastening mechanism is attached to the second portion of the fastening mechanism and forms a conduit to support the image capture device. The conduit includes an inner surface and an outer surface, and the outer surface of the conduit is at least partially defined by the polymer layer. An image capture device is mounted to an end portion of the flexible member.
