Abstract
According to some embodiments, the present technology includes a device for the disruption and/or removal of obstructive material in a blood vessel. The device can comprise an elongated shaft having a proximal portion, a distal portion, and a lumen extending therebetween. The device can further comprise a capture structure carried by the distal portion of the elongated shaft and having a greater cross-sectional dimension than a cross-sectional dimension of the elongated shaft. The capture structure can comprise an opening at a first end portion that is fluidly coupled to the lumen of the elongated shaft, a fluid impermeable sidewall enclosing an interior region, and an opening extending through a thickness of the sidewall. A portion of the sidewall surrounding the opening can be configured to deform towards or away from the interior region such that a cross-sectional dimension of the opening increases to receive the obstructive material therethrough.
