Abstract: A percutaneous circulatory support device includes a housing and an impeller disposed within the housing. The impeller is rotatable relative to the housing to cause blood to flow through the housing. A cannula is coupled to the housing, and a distal tip portion is coupled to the cannula opposite the housing. The distal tip portion includes an inner shaping core configured to maintain a predetermined shape of the distal tip portion and an outer layer disposed outwardly from the inner shaping core or the distal tip portion includes an atraumatic, sphere-shaped distal end.

Abstract: Pressure sensing guidewires are disclosed. The pressure sensing guidewires may include a tubular member having a proximal portion and a distal portion. The distal portion may have a plurality of slots formed therein. The distal portion may have a first wall thickness along a first region and a second wall thickness smaller than the first wall thickness along a second region. A pressure sensor may be disposed within the distal portion of the tubular member and housed within the second region. An anti-thrombogenic coating may be disposed on an inner surface, an outer surface, or both of the second region of the distal portion of the tubular member.
