  • Patent number: 11944349
    Abstract: A vascular closure device assembly, comprises a sheath comprising: a sheath main body defining a channel therethrough, a sheath engagement portion, and a sheath mounting portion located at a proximal end of the sheath main body. The assembly comprises a housing within which the sheath mounting portion is secured such that the sheath is rotatable relative to the housing, and such that the housing inhibits axial displacement of the sheath relative to the housing. The assembly also includes a dilator comprising a dilator main body, and a dilator engagement portion extending from the dilator main body towards the sheath. The dilator engagement portion is configured to engage the sheath engagement portion such that axial displacement of the dilator relative to the sheath causes the sheath to rotate relative to the housing, and wherein the housing is configured to inhibit axial displacement of the sheath during rotation.

  • Publication number: 20230001167
    Abstract: The present invention relates to a dilator. The dilator includes a shaft, a lumen and a hub. The shaft has at least two stiffness sections with the stiffness sections becoming less rigid as they approach a distal end of the shaft. The varying stiffness sections allow the dilator to track along the guidewire through torturous vasculature so as the dilator is advanced and the stiffness is changed, the stiffer sheath can advance smoothly through a blood vessel. The dilator may also taper at the distal tip to stretch the initial skin puncture hole larger to accommodate the dilator shaft and ease the sheath tip insertion through to the vasculature. Or the shaft may taper from where it extends beyond the sheath distal tip to the distal end so that it can reach further distal in the vasculature. The dilator may also include an atraumatic tip for easier advancement of the dilator. The dilator distal end may also include one or more radiopaque markers and a shaped distal end.

  • Publication number: 20220280143
    Abstract: A system for performing vascular hemostasis comprises a balloon insertable into a tissue track so as to be disposed outside a vessel above an opening formed in the vessel. A hemostasis layer is removably disposed on at least a portion of an outer surface of the balloon. A balloon tube is fluidly coupled to the balloon and configured to selectively inflate or deflate the balloon. The balloon is inflatable above the opening such that the hemostasis layer is disposed on the outer surface of the vessel and closes the opening. The hemostasis layer is separable from the balloon so as to remain disposed on the outer surface of the vessel when the balloon is removed from the tissue track, and continues to close the opening after removal of the balloon.

  • Patent number: 11219447
    Abstract: Excess suture material may be trimmed after knot tying using a device having an elongated shaft, an elongated tubular cutter disposed over the shaft and an elongated tubular barrel disposed over the cutter. A suture loader at a distal end of the shaft that engages suture material may be opened and closed by a first actuator that causes relative motion between the shaft and the barrel. A second actuator may cause relative motion between the cutter and both of the barrel and the shaft to sever suture material engaged by the closed suture loader.

  • Patent number: 11076849
    Abstract: An elongated deployment shaft carrying a needle deployment assembly with needles carrying sutures and a stabilizer. A catcher tube over the shaft having a catcher assembly at a distal end may retain a portion of the needles when passed through the tissue into engagement with catcher assembly. The catcher and needle deployment assemblies are configured to asynchronously engage the plurality of needles when moved distally beyond the catcher assembly. A sheath over the catcher tube may sandwich the tissue against the stabilizer when expanded. A first actuator may move catcher tube distally to decrease distance between proximal and distal ends of the stabilizer expand it and may move the sheath distally to sandwich the tissue. A second actuator may deflect the needles outward to move proximally through the tissue and engage the catcher and return a portion of each not retained by the catcher to a distal position.
