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: 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 region coupled to the distal zone of the elongated shaft, a cover, and a connector coupling the cover to the distal zone of the elongated shaft. The device may further include a jacket at least partially over the proximal terminus of the connector and a portion of the filaments protruding from the connector.

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 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, a cover, and a connector coupled to the distal zone of elongated shaft. The connector may include an inner band and an outer band. The inner band may at least partially surround the distal zone of the elongated shaft and a portion of the proximal region of the capture structure, and the outer band may at least partially surround the inner band. In some embodiments, the first end portion of the cover may be secured between the inner band and the outer band.

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 member, a cover having proximal, intermediate, and distal portions. The cover may be slideably coupled to the distal region of the elongated member at a connector. The cover may have an inner layer and an outer layer. The inner layer may have (a) a first cross-sectional dimension at the proximal portion of the cover, (b) a distally increasing cross-sectional dimension along the intermediate portion of the cover, and (c) a second cross-sectional dimension at the distal portion of the cover, wherein the second cross-sectional dimension is greater than the first cross-sectional dimension. The outer layer may have a cross-sectional dimension that is generally constant along the distal portion and the intermediate portion of the cover.

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, a cover, and a connector coupled to the elongated shaft proximal of the capture structure. The connector may include an inner band and an outer band, wherein (a) the inner band at least partially surrounds a portion of the distal zone of the elongated shaft, (b) the outer band at least partially surrounds the inner band, and (c) the first portion of the cover is secured between the inner band and the outer band.

Abstract: An apparatus for administering ingestible liquids in a serial flow relationship, including a first tubular member having a first diameter, a second tubular member having a second diameter, a hollow intermediate member having a first end, a second end, and a chamber defined therein by an interior surface, and a valve member positioned within the chamber of the intermediate member. The first tubular member is in flow communication with the first end of the intermediate member and the second tubular member is in flow communication with the second end of the intermediate member. The chamber of the intermediate member is divided into first and second portions by the valve member. Accordingly, a first ingestible liquid contained within the first tubular member and a second ingestible liquid contained within the second tubular member are maintained in segregated relation until administration of the first and second ingestible liquids.
