    Abstract: A guidewire comprising: a core wire; an elongated member extending along a longitudinal axis and defining: an inner surface defining an inner lumen, a plurality of openings disposed along the elongated member, each opening extending from an outer surface of the elongated member towards the inner surface, a first locking recess extending through the elongated member from the outer surface to the inner surface, a second locking recess extending from the inner surface towards a second location on the outer surface, wherein the first locking recess and the second locking recess defines a locking channel; and a locking element disposed within the locking channel and affixed to the elongated member, the locking element defining an aperture configured to receive the core wire, wherein the locking element is configured to inhibit unintended proximal movement of the core wire along the longitudinal axis relative to the elongated member.

    Abstract: Systems and methods for removing clots via aspiration are disclosed herein. A catheter includes an elongate body defining a lumen. The distal region includes a distal openings region, a proximal openings region and a thrombus interface region between the distal and the proximal openings regions. The distal and proximal openings regions each includes one or more openings in fluid communication with the lumen. In use, the catheter is positioned from a proximal side of the clot so that the distal openings region positioned at least partially distal of the clot and the proximal openings region positioned at least partially proximal of the clot. An aspiration catheter is positioned with its distal end at the proximal end of the clot. The clot is then withdrawn in the proximal direction with a combination of aspiration applied to one or more of the catheter or the aspiration catheter.

    Abstract: Injectable biopolymer compositions and associated systems and methods are disclosed herein. In some embodiments, a biopolymer composition for treating an aneurysm is provided. The biopolymer composition can include an injectable hydrogel including: a biopolymer; a chemical crosslinker forming covalent bonds with the biopolymer; and a stabilizer configured to inhibit ex vivo precipitation of the biopolymer. The injectable hydrogel can have an ex vivo storage modulus of at least 100 Pa at 37° C. over a linear viscoelastic region of the injectable hydrogel. The ex vivo storage modulus can be greater than an ex vivo loss modulus of the injectable hydrogel over the linear viscoelastic region of the injectable hydrogel.
