  • Patent number: 11376028
    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.

  • Patent number: 10626572
    Abstract: An apparatus and method for endwise connecting subterranean barrier members is disclosed. The apparatus includes at least two barrier members with each barrier member extending between top and bottom edges. Further, each barrier member has a side first edge having a flange defining a first connector and an opposed second side edge having a channel defining a second connector. The channel is sized and shaped to receive the flange of an adjacent barrier member in slidable interconnection therein. The apparatus further include a first side panel shaped to lie against a first side of the barrier members, a second side panel shaped to lie against a second side of the barrier members and a bridging plate located between the first and second panel members so as to bridge a gap therebetween, wherein the gap has a width corresponding to a width of the first and second barrier members. The associated method is directed toward creating the apparatus.
