Abstract: Devices for removing clot material from a blood vessel lumen and associated systems and methods are disclosed herein. A clot retrieving device may include, for example, an elongated shaft, a capture structure having a proximal portion and a distal portion, and a cover having a first portion coupled to the elongated shaft and a second portion extending from the first portion. The cover may have an inverted configuration in which the capture structure is at least partially ensheathed within the first portion of the cover and the second portion of the cover extends distally from the first portion. In the inverted configuration, the second portion may have (a) a first region distal to a distal terminus of the capture structure, the first region tapering radially inwardly in a distal direction, and (b) a second region extending distally and radially outwardly from the first region.

Abstract: Devices and methods for securing a cover of a retrieval device while the retrieval device is resheathed to a more proximal position within a delivery sheath are disclosed herein. A retrieval device may include, for example, a securing element configured to grip the cover when the retrieval device is pulled proximally, to thereby secure the cover. A method of positioning the retrieval device may include, for example: (a) advancing the retrieval device distally through a delivery sheath to a partially deployed state while the securing element is in a first state, and (b) retracting the clot retrieval proximally from the partially deployed state while the securing element is in a second state that grips the cover to secure the cover.

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 can include an elongate manipulation member, and a thrombectomy device connected to the elongate manipulation member. The thrombectomy device can have a first configuration and a second configuration, the thrombectomy device being expandable from the first configuration to the second configuration. The thrombectomy device can include an arcuate marker-mounting projection attached to a portion of the thrombectomy device configured to contact a thrombus. A marker can be coupled to, and extending around, the arcuate marker-mounting projection with the marker and the arcuate marker-mounting projection contacting each other at three discrete locations. A method for engaging a thrombus can include advancing a thrombectomy device to a location radially adjacent to a thrombus in a blood vessel.

Abstract: A ball-tipped mandrel, separate or integrated on a device delivery assembly, can be used to ease delivery and/or retrieval of an ancillary device within a body vessel having tortuous anatomy. A ball-tipped mandrel can be moved through a catheter as a part of a preparation procedure prior to insertion into a body vessel of a patient. A ball-tipped mandrel can be moved through a catheter during or after insertion into a body vessel of a patient in preparation for delivery of an ancillary device. A ball-tipped mandrel can be integrated onto the distal portion of a device to produce dilation during device delivery.
