Abstract: A method of loading an expandable stent into a delivery device may include positioning a middle portion of the expandable stent in a collapsing fixture including a passage extending therethrough, radially compressing the middle portion of the expandable stent in the passage before any other portion of the expandable stent while a first end of the expandable stent is disposed outside of the passage, moving the collapsing fixture relative to the expandable stent, radially compressing the expandable stent from the middle portion toward the first end of the expandable stent, and inserting the first end of the expandable stent followed by the middle portion of the expandable stent into a distal end of an elongate outer sheath of the delivery device.

Abstract: A stent delivery device is provided that includes an inner member defining a distal tip and a stent holding region, and an outer tubular member slidingly disposed over the inner member and configured to engage the distal tip. Seal members may be disposed on one or more of an outer surface of the inner member, the distal tip, and the outer tubular member. The seal members define a liquid-tight sealed chamber surrounding the stent holding region.

Abstract: Medical devices, assemblies and methods for guarding sharp tips of medical needles are disclosed herein. Some embodiments include an expandable device configured to be at least partially disposed within the needle lumen. The device may include an expandable distal portion that is designed to shift between a first configuration in which the expandable distal portion has an outer diameter that is the same as or less than the inner diameter of the needle lumen and a second configuration in which the expandable distal portion has an outer diameter that is greater than the inner diameter of the needle lumen. An elongated inner member may be used to shift the expandable distal portion from the first configuration to the second configuration.
