    Abstract: Systems and methods for the intravascular treatment of clot material within a blood vessel of a human patient are disclosed herein. In one embodiment, a system includes a coring element for coring and separating the clot material. The coring element can comprise a unitary structure having a first region, a second region, a third region, and a fourth region. The first region is adjacent to a proximal portion of the unitary structure and includes a first mouth configured to core and separate the clot material. The second region is distal of the first region, generally tubular, and includes a first plurality of interconnected struts. The third region is distal of the second region and includes a second mouth configured to core and separate the vascular thrombus. The fourth region is distal of the third region, generally tubular, and includes a second plurality of interconnected struts.

    Abstract: Systems and methods for the intravascular treatment of clot material within a blood vessel of a human patient are disclosed herein. A device in accordance with embodiments of the present technology can include, for example, a plurality of interconnected struts forming a unitary structure having a proximal portion and a distal portion. The struts can form a plurality of first cells in the proximal portion and a plurality of second cells, smaller than the first cells, in the distal portion. The device can be pulled against clot material within a blood vessel to engage, disrupt, and/or capture the clot material.

    Abstract: Disclosed herein are devices, systems, and methods for adjustably tensioning sutures, such as sutures used to close a catheter access site of a human patient. In some embodiments, a suture tensioning device includes a housing and an actuation member slidably coupled to the housing. The housing can include a first through-hole and a second through-hole at least partially aligned along an axis. The actuation member can include a third-through-hole. The suture tensioning device can further include a biasing member operably coupled between the actuation member and the housing. The biasing member can bias the actuation member to a first position in which the third through-hole is offset from the axis. The actuation member is movable to a second position in which the third through-hole is at least partially aligned with the first and second through-holes along the axis.

    Abstract: Systems and methods for the intravascular treatment of clot material within a blood vessel of a human patient are disclosed herein. A method in accordance with embodiments of the present technology can include, for example, positioning a distal portion of a catheter proximate to the clot material within the blood vessel. The method can further include coupling a pressure source to the catheter via a tubing subsystem including a valve or other fluid control device and, while the valve is closed, activating the pressure source to charge a vacuum. The valve can then be opened to apply the vacuum to the catheter to thereby aspirate at least a portion of the clot material from the blood vessel and into the catheter.

    Abstract: Devices, systems, and methods for sealing medical devices, particularly during intravascular access, are disclosed herein. Some aspects relate to a hemostatic valve for sealing a wide range of medical devices, such as catheters, wires, embolectomy systems. The valve can include an elongate member having a first end, a second end, and a central lumen extending therebetween. A reinforcement structure extends along at least a portion of the elongate member and is coupled to the elongate member. A shell defining a first aperture and a second aperture may be included, which first and second apertures can be fluidly coupled by the elongate member. A tensioning mechanism is coupled to the shell and to the elongate member, the tensioning mechanism can be moveable between a first configuration wherein the tensioning mechanism is collapsed and the central lumen is sealed and a second configuration wherein the central lumen is open.

    Abstract: Systems and methods for removal of thrombus from a blood vessel in a body of a patient are disclosed herein. The method can include: providing a thrombus extraction device including a proximal self-expanding member formed of a unitary fenestrated structure, a distal substantially cylindrical portion formed of a net-like filament mesh structure, and an inner shaft member connected to a distal end of the net-like filament mesh structure; advancing a catheter constraining the thrombus extraction device through a vascular thrombus, deploying the thrombus extraction; retracting the thrombus extraction device to separate a portion of the thrombus from the vessel wall and to capture the portion of the thrombus within the net-like filament mesh structure; and withdrawing the thrombus extraction device from the body to remove thrombus from the patient.

    Abstract: Disclosed herein are clot removal systems including steerable catheters, and associated systems and methods. In some embodiments, a clot removal system includes (i) an aspiration catheter having a proximal region and a distal region and (ii) a handle coupled to the proximal region of the catheter and having an actuator. The distal region of the catheter can include a deflectable member, and the clot removal system can include a pull wire extending between the actuator and the deflectable member. Actuation of the actuator is configured to pull the pull wire to deflect the deflectable member to deflect the distal region relative to the proximal region. The deflection can facilitate steering of the catheter to hard-to-reach (e.g., tortuous) portions of the anatomy of a patient.
