Abstract: According to some embodiments, the present technology includes device for removing obstructive material from a blood vessel lumen. For example, the device can comprise an elongated member, a cutting portion carried by a distal region of the elongated member, and a capture portion carried by the distal region of the elongated member. The cutting portion can comprise a blade configured to separate at least a portion of the obstructive material from the blood vessel wall, and the capture portion can comprise a mesh structure configured to enmesh and/or capture at least a portion of the obstructive material.

Abstract: Endovascular treatment devices are disclosed herein. According to some embodiments, the present technology includes an elongate control member and an expandable basket coupled to a distal portion of the control member. The basket can comprise a plurality of braided filaments having a proximal opening surrounding by a proximal edge. The basket can further comprise first and second legs having respective proximal ends coupled to the control member at a connection and distal ends at the proximal edge of the basket. Each of the first and second legs can be formed of bundled portions of the filaments. The first and second legs can be configured to position the basket within the blood vessel lumen independent of the path of the control member such that the proximal edge of the basket remains in contact with an inner surface of the blood vessel lumen when the basket is positioned around a curve.

Abstract: A medical device for removing a material from a hollow anatomical structure is provided. The device may include a shaft member. The device may include an expandable centering element near the distal end of the device. The device may include a macerator element either attached to the shaft or independent and freely moveable from the shaft. Alternatively, the device may include a rotating wire attached to the macerator element. The device may include an aspiration lumen in for removal of material. The device may include a drive shaft attached to a motor and used to rotate the macerator element. The device may be used in combination with a distal occlusion element, which may be either a radially expandable filter or balloon member.

Abstract: According to some embodiments, the present technology includes devices and systems for removing obstructive material from a blood vessel lumen. For example, the system can comprise a first elongated member, a second elongated member, and a cutting element configured to cut obstructive material at the treatment site. Rotation of the second elongated member relative to the first elongated member, or vice versa, can cause the cutting element to expand away from a longitudinal axis of the second elongated member. The system can further include an expandable positioning element configured to be intravascularly delivered to the treatment site, where the positioning element can be configured to expand into apposition with the vessel wall to position the cutting element closer to the obstructive material than before expansion of the positioning element.
