  • Patent number: 10413310
    Abstract: Devices for restoring blood flow to facilitate lysis of clots and/or enable capture of clots are disclosed. The devices can be configured to be disposed within a lumen of a microcatheter that is inserted within neurovasculature above a carotid siphon to a location of a clot. The devices can include an elongate pusher member and a self-expandable capturing member coupled to a distal end of the elongate pusher member. The capturing member can comprise a generally cylindrical body having an cell structure that is configured to compress the clot against an inner wall of the neurovasculature and capture the clot at least partially on a surface of the generally cylindrical body upon deployment of the capturing member from the microcatheter, thereby restoring blood flow to the neurovasculature downstream of the clot.

  • Patent number: 10405880
    Abstract: A rotatable cutter for a tissue-removing catheter includes a central hub, flutes spaced apart from one another around the circumference of the central hub, and arcuate cutting members. Each cutting member includes an arcuate cutting edge extending along an arc length of the cutting member for cutting tissue as the cutter is rotated. A raised element of each cutting member has a leading cutting edge at a leading end of the distal cutting member for cutting tissue as the cutter is rotated. A clearance portion of each cutting member is recessed, relative to the longitudinal axis of the cutter, from the raised element and extends from the raised element to a trailing end of the cutting member to provide clearance for the leading cutting edge of an adjacent and opposing distal cutting member.

  • Patent number: 10363113
    Abstract: An adjustable containment shield is operable to mount on an output housing of a surgical instrument. The shield includes a substantially transparent body including a distal face, a proximal face opposite the distal face, a generally consistent thickness defined between the distal face and the proximal face such that the body is pliable and resilient, a mounting hole defined in the body to engage the output housing, and a plurality of folds to allow the shield to move from a retracted position to an expanded position. When mounted on the output housing, the distal face is at an acute angle with respect to a longitudinal axis through the mounting hole and face is also facing toward a patient engagement end of the surgical instrument. The proximal face is at an obtuse angle with respect to the longitudinal axis and facing toward a housing side of the surgical instrument.

  • Patent number: 10363054
    Abstract: A clot retrieval device for removal of occlusive clot from a blood vessel comprises a clot engaging element 700 having a constrained delivery configuration and an expanded deployed configuration. In the expanded configuration peripheral portions are laterally spaced-apart and the clot engaging section 700 extends between the peripheral portions. The device 700 may have two superimposed wave patterns provided by a large amplitude curve 723 and shorter pitch sinusoidal patterns 721, 722. A wave shape varies the contact pressure between a clot and the device along the length of the device, reducing the compression of the clot by the device at some locations. The device can elongate when placed under tension which aids elongation of the clot during dislodgement.

  • Patent number: 10357276
    Abstract: A medical device includes an expandable-and-contractible member capable of radially expanding and radially contracting, an incising member disposed on an outer circumference of the expandable-and-contractible member and having a hollow portion, a core wire inserted in the hollow portion, a distal tip, and a ring. The core wire is capable of sliding in a longitudinal direction of the medical device as the expandable-and-contractible member expands or contracts. The incising member is therefore not likely to come off upon radial expansion or radial contraction of the expandable-and-contractible member, and is therefore not likely to interfere with the expanding or contracting movement of the expandable-and-contractible member.
