    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: A method for treating an aneurysm in accordance with a particular embodiment of the present technology includes intravascularly delivering a mixture including a biopolymer (e.g., chitosan) and a chemical crosslinking agent (e.g., genipin) to an aneurysm. The method further includes mixing the biopolymer and the chemical crosslinking agent to initiate chemical crosslinking of the biopolymer. The mixture is delivered to the aneurysm via a lumen and an exit port of a catheter while the chemical crosslinking is ongoing. The mixture exits the catheter as a single cohesive strand that at least partially agglomerates to form a mass occupying at least 75% of a total internal volume of the aneurysm. During delivery of the mixture, the method includes expanding a tubular flow diverter to reinforce a neck of the aneurysm.

    Abstract: A medical device, for insertion into an anatomical vessel, can include a sheath, a delivery wire, and a frame or vessel-engaging member. The delivery wire can have a first stop, a second stop, and a coupling area between the first and second stops. The coupling area can be disposed within and movable relative to the sheath. The frame or vessel-engaging member can have a matrix of cells, first and second tapered sections, and interlocking members. The interlocking members can be attached to the tapered sections. The interlocking members can be releasably coupled to the delivery wire at the coupling area with the interlocking members surrounded and held in the coupling area by the sheath. The interlocking members can be movable relative to the sheath, and the interlocking members can separate from each other when the interlocking members are positioned distal to the sheath.

    Abstract: A medical device is provided. The medical device includes a vessel-engaging member attached to a distal end of a delivery wire via a connection mechanism. The vessel-engaging member includes a plurality of rows and a plurality of bridges positioned between each adjacent row, each of the bridges connecting a vertex of a first row with a corresponding vertex of a second row. The vessel-engaging member further includes first and second tapered sections coupled to the connection mechanism, each of the tapered sections projecting from a proximal row and tapering in a direction from the proximal row toward the connection mechanism, each of the tapered sections having a length measured along a longitudinal axis, wherein the length of the first tapered section is less than the length of the second tapered section.
