Abstract: Provided herein is a recanalization system including (i) a handle located at a proximal end of the system, (ii) a first elongate member, (iii) a second elongate member, the first and second elongate members being movable relative to each other elongate member, and (iv) a recanalization device located at a distal end of the system. The recanalization device includes (i) a first end portion coupled to the first elongate member, (ii) a second end portion coupled to the second elongate member, and (iii) at least one strut extending between the first and second end portions. The recanalization device is configured to be (i) selectively radially expanded and compressed and (ii) axially moved relative to the first and second elongate members.

Abstract: A stent delivery system can include a core member, a stent, and a stent engagement member. The engagement member can be positioned along a distal segment of the core member and be coupled to the core member. The engagement member can have an outer surface. The stent can extending along the core member distal segment such that the outer surface of the engagement member engages an inner surface of the stent along at least a portion of only a distal half of the stent for transmitting an axial force from the core member to only the stent distal half of the stent.
