  • Patent number: 11035417
    Abstract: A boot assembly for a joint includes a boot and a boot can coupled to the boot at a connecting portion. The boot can includes a mounting portion including a flange having an inner surface and a retainer. The retainer is connected to the flange at a first location and is separate from the flange at a second location spaced from the first location. The retainer includes an inward portion spaced from the first location, and the inward portion is arranged closer to the axis than is the inner surface of the retainer between the first location and a midpoint of the retainer. The inner surface of the retainer is not at a constant angle relative to the axis along the length of the retainer.

  • Patent number: 10274020
    Abstract: A joint for coupling two shafts in a vehicle driveline includes a joint part having a bore defining part of a fluid chamber, a boot member coupled to the joint part and defining at least part of the fluid chamber and having a valve portion that has an open state and a closed state, and an insert. The insert may be received adjacent to the boot member and defines at least part of a vent path that communicates the fluid chamber with the valve portion. When the valve portion is in the closed state venting from the vent chamber is inhibited or prevented and when the valve portion is in the open state the vent chamber is communicated with a venting space.

  • Patent number: 8152832
    Abstract: Anchoring mechanisms for releasably securing an intravascular device along an elongated member such as a guidewire or catheter. The anchoring mechanism may include an object that can be actuated between an unlocked position and a locked position. In the unlocked position, the anchoring mechanism is slidably and rotationally disposed about the elongated member. In the locked position, the anchoring mechanism is releasably secured to the elongated member, preventing movement thereon. A placement mechanism such as a tubular member can be utilized to actuate the anchoring mechanism between the unlocked and locked positions.

  • Patent number: 7780696
    Abstract: An emboli capturing system captures emboli in a body lumen. A first elongate member has a proximal end and a distal end. An expandable emboli capturing device is mounted proximate the distal end of the first elongate member, and is movable between a radially expanded position and a radially contracted position. When in the expanded position, the emboli capturing device forms a basket with a proximally opening mouth. A second elongate member has a proximal and a distal end with a lumen extending therebetween. The lumen is sized to slidably receive a portion of the first elongate member. An expandable delivery device is mounted to the distal end of the second elongate member and is movable from a radially retracted position to a radially expanded position. The delivery device has a receiving end configured to receive the emboli capturing device, and retains at least the mouth of the emboli capturing device in a radially retracted position.

  • Patent number: 7320697
    Abstract: Apparatus and methods are provided for use in filtering emboli from a vessel, wherein a vascular filter is disposed on a guide wire, the vascular filter having a support hoop disposed from a suspension strut so as to permit lateral eccentric displacement of the support hoop relative to a longitudinal axis of the guide wire. A blood permeable sac is affixed to the support hoop to form a mouth of the blood permeable sac. The support hoop is disposed obliquely relative to the guide wire and is capable of being properly used in a wide range of vessel diameters. The support hoop collapses the mouth of the blood permeable sac during removal of the vascular filter to prevent material from escaping from the sac. A delivery sheath and introducer sheath for use with the vascular filter of the present invention are also provided.
