Abstract: A stent delivery system can include a core member, first and second restraints, and a stent engagement component. The core member can have a distal segment. The first and second restraints can be coupled to the core member distal segment and axially spaced apart from each other to provide an axial gap. The first and second restraints can each have an outer profile that tapers radially inwardly in directions away from the gap. The stent engagement component can be at least partially disposed in the axial gap between the first and second restraints such that the component is slidably and rotatably coupled to the core member distal segment.

Abstract: A medical device, configured to perform an endovascular therapy, e.g., thrombectomy, can comprise an elongate manipulation member having a first connection member proximate a distal end of the elongate manipulation member, and an intervention member having a second connection member proximate a proximal end of the intervention member. The second connection member can be connected to the first connection member such that the first connection member can rotate relative to the second connection member.

Abstract: A stent delivery system, a core assembly, and methods of operating the same are provided. The delivery system can comprise a catheter and the core assembly. The core assembly can comprise a constraining member, protruding member, a core member, and a stent extending along the core member. The tubular constraining member can be spaced apart from the core member and define a capture area. The protruding member can be disposed along the core member at least partially distal of the capture area. The stent can have a first portion disposed within the capture area and a second portion, distal to the first portion, extending across or over an outer surface of the protruding member so that the protruding member and the constraining member cooperate to inhibit expansion of the first portion of the stent.

Abstract: Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the thrombectomy system. The system can include a catheter having a distal portion configured to be positioned adjacent to a thrombus in a blood vessel, an electrode disposed at the distal portion of the catheter, and an interventional element configured to be delivered through a lumen of the catheter. The electrode and the interventional element are each configured to be electrically coupled to an extracorporeal power supply.

Abstract: A system can comprise a catheter and a device having an elongate member and an expandable member. The expandable member can be coupled to the elongate member. The elongate member can extend through the catheter. The expandable member can be positioned with a proximal member end proximal to a distal catheter end, a distal member end positioned distal to the distal catheter end, and at least a portion of the expandable member between the distal catheter end and the distal member end in an expanded state in which a maximum transverse dimension of the expandable member is larger than a maximum transverse dimension of the distal member end. The catheter can be advanced in a patient's body with the expandable structure, in the expanded state, at the distal end of the catheter.
