  • Publication number: 20140114140
    Abstract: A tissue retractor device suitable for spinal surgery. The device includes base apparatus to which three blades are circumferentially hinged, the blades closing upon each other in default position from spring bias. A pusher mechanism is threadably connected to the base which spreads the blades by rotating the pusher in its threads relative to the base, which converts rotational motion to translational motion to angular motion of the blades about their respective hinges. One blade is longer than the others to present a multipurpose tip to the user of the device, such a tip being useful in avoiding nerve roots or other anatomy obstructing the surgical path. A dilator is threadably connected to the pusher, the dilator having a long hollow tube connected to a hollow tip extending beyond the blades to slide over guide-wire and initially position the device at the operative site, prior to using the pusher to retract patient's tissue.

  • Patent number: 8668668
    Abstract: Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, small cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The sheath is configured for use in the vascular system and has utility in the introduction and removal of implant delivery catheters. The access route is through the femoral arteries and the iliac arteries into the aorta. The distal end of the sheath is maintained in the first, low cross-sectional configuration during advancement to the arteries into the aorta. The distal end of the sheath is subsequently expanded using a radial dilatation device, which is removed prior to the introduction of implant delivery catheters. In an exemplary application, the sheath includes a supported proximal end, a supported distal end, and a collapsible center section.

  • Patent number: 8608702
    Abstract: An introducer for providing intravascular access to a patient is disclosed, and includes a dilator and sheath that are configured to prevent peelback, or “fishmouthing,” of the sheath during introducer advancement. In one embodiment, the introducer comprises a dilator including a distal tapered region, and a sheath including an inner bore that receives the dilator such that a portion of the tapered region of the dilator extends from the sheath distal end. A distal outer surface of the sheath includes a first curved portion defined by a first radius and extending proximally from the distal end of the sheath to a first end point, and a second curved portion defined by a second radius and extending proximally from the first end point to a second end point. Additionally, an interference fit is established between the dilator tapered region and the sheath distal end to further prevent sheath end deformation.

  • Patent number: 8603036
    Abstract: A vascular introducer for accessing a circulatory system of a patient includes a sheath and a dilator. The sheath includes a fitting attached at a proximal end, and includes a liner that is longer than a core tube. A proximal segment of the liner is attached to an inner surface of the core tube, but a distal segment of the liner is everted to cover an outer surface of a distal segment of the core tube. The dilator is positioned in the sheath and includes a tapered distal segment that extends beyond a distal end of the sheath. A handle is attached to the proximal end of the dilator and extends proximally from the fitting. During a procedure, a blood vessel may constrict and grip the sheath. During withdrawal of the sheath, the core tube is slid within a first portion of the everted distal segment of the liner while another portion of the liner is de-everting.
