  • Publication number: 20210275161
    Abstract: A surgical anchoring device may include a first beam and a second beam each extending along a longitudinal direction; and a connecting member bridging a first proximal portion of the first beam to a second proximal portion of the second beam such that the first beam is substantially aligned with the second beam. In addition, the anchoring device may include a first barb protruding from a medial side of the first beam, wherein the first barb extends diagonally in a generally proximal direction; and a second barb protruding from a medial side of the second beam, wherein the second barb extends diagonally in a generally proximal direction. The first barb may include a proximal facing surface that is separated from the first beam by a recess.

  • Publication number: 20210275322
    Abstract: An implant delivery device may include an implant holding portion proximate the distal end, the implant holding portion being configured to retain a sheet-like implant during implantation of the implant. In addition, the implant holding portion may be configured to receive the implant with a fixed implant supporting flange member configured to support the implant on one side, and a movable implant supporting flange member. The movable implant supporting flange member may be configured to be slidable between a distal position and a proximal position, wherein, in the distal position, the movable implant supporting flange member and secures the implant against the fixed implant supporting flange member, and in the proximal position, the movable implant supporting flange member is withdrawn from the distal end of the implant delivery device, thus enabling release of the implant.

  • Publication number: 20190290315
    Abstract: A direct stream hydrodynamic catheter system is provided for the removal of thrombus, lesions and the like including provisions for the infusion of drugs, lysing fluids and the like into a blood vessel. Physician controlled powered direct fluid jet streams emanate from a fluid jet emanatory in the form of robust radially directed fluid jet streams to impinge upon and ablate difficult and strong thrombus and lesions within a blood vessel. Effluent aspiration is controlled by an exhaust regulator in the form of a roller pump, but effluent removal can be assistingly influenced by the fluid pressure associated with the radially directed fluid jet streams.

  • Patent number: 9585686
    Abstract: An infusion flow guidewire and a system including an infusion flow guidewire. The minimal cross section flexible infusion flow guidewire includes a nitinol hypotube, a flexible tip having a closed distal end, a coil, a core wire and at least one distally located rearwardly directed jet orifice for infusion of fibrinolytics and for introduction of high pressure fluids for maceration and rearwardly directed flow of thrombus debris located in tortuous small sized vessels. Apparatus, some of which is removably attachable, is provided in the system for grasping members of the invention for rotational torqueing and for longitudinal actuation along and within the vasculature.

  • Patent number: 9238119
    Abstract: Fluid infusion systems and fluid couplings are described herein. The infusion systems may include one or more fluid couplings used to make fluidic connection between a supply line and delivery tubing. The fluid couplings separate the functions of providing a seal around a delivery tube and retaining the delivery tube within the fluid coupling. The seal provided around the delivery tube prevents leakage around an exterior surface of a delivery tube such that fluid passing through the coupling must pass through the delivery tube rather than leak around the delivery tube. The structure used to retain the delivery tube in the fluid coupling prevents ejection of the delivery tube from the coupling due to the fluid pressures present in the coupling. The separate functions are performed by different structures within the fluid couplings.

  • Patent number: 8657777
    Abstract: Catheters including guidewire tubes having a limited length and methods of using the catheters are described. The catheters may be delivered over guidewires in procedures that are commonly referred to as rapid-exchange delivery. In some embodiments, the catheters may be miniature flexible thrombectomy catheters that may be used to remove thrombus or other unwanted material from a body blood vessel or other small regions of body cavities in which the distal portion of the catheter has smaller external dimensions than the larger proximal portion.
