  • Patent number: 10111664
    Abstract: A closure system and methods of use are provided for use in sealing an opening in a body tissue, such as a vascular puncture site. A method of closing the opening in the body tissue can be performed with the closure system having a closure clip. The method can include positioning the closure clip in a first closure clip position adjacent to the opening in the body tissue such that a plurality of spikes of the closure clip are inserted into the tissue at a location outward from a central axis of the opening. Subsequently, the closure clip can be positioned in a second closure clip position such that the plurality of spikes are pulled inward toward the central axis of the opening so as to pull the tissue between the opening and each of the spikes together and close the opening.

  • Patent number: 8758400
    Abstract: An apparatus for sealing a passage through tissue communicating with a body lumen is provided. The apparatus includes an elongate member having a proximal end a distal end and a lumen extending from the distal end toward the proximal end defining a longitudinal axis. A plug member is disposed on the distal end and extends distally from the elongate member in a pre-deployed and deployed configuration. The plug member includes a distal port therein in communication with the lumen and has a cross-sectional diameter at a plug proximal end and a plug distal end greater than a cross-sectional diameter of the distal end of the elongate member in the pre-deployed configuration. The apparatus also includes a member extendable distally from the distal port, the member including a proximal end and a distal end.

  • Patent number: 6796945
    Abstract: An intravascular imaging guidewire is provided that can accomplish longitudinal translation of an imaging plane allowing imaging of an axial length of a region of interest without moving the guidewire. The imaging guidewire comprises a body in the form of a flexible elongate tubular member. An elongate flexible imaging core is slidably received within the body. The imaging core includes a shaft having an imaging device mounted on its distal end. The body and the imaging core are cooperatively constructed to enable axial translation of the imaging core and imaging device relative to the body. The body has a substantially transparent portion extending an axial length over which axially translatable imaging may be performed. The imaging guidewire has a maximum diameter over its entire length sized to be received within a guidewire lumen of an intravascular catheter.

  • Publication number: 20040083002
    Abstract: Apparatus and methods for treating a spinal disc are disclosed. An opening is created in the annulus fibrosis, and nucleus pulposus is removed from the interior of the disc. The interior is lined with a nonporous, bioabsorbable liner, and filled with a fill material, such as nucleus pulposus, to cause the liner to expand to engage tissue surrounding the interior. The liner may be a sheet of extra-cellular matrix material that is introduced into the interior, or a bladder of extra-cellular matrix material including a neck communicating with an interior region of the bladder. The sheet or bladder may be carried by a delivery device, e.g., a catheter or rod. After the interior region is filled, the opening is closed using a plug or other closure device. The plug may include threads on its external surface for securing the plug in the opening.

  • Publication number: 20030114744
    Abstract: An intravascular imaging guidewire which can accomplish longitudinal translation of an imaging plane allowing imaging, by acoustic or light energy, of an axial length of a region of interest without moving the guidewire. The imaging guidewire comprises a body in the form of a flexible elongate tubular member. An elongate flexible imaging core is slidably received within the body. The imaging core includes a shaft having an imaging device mounted on its distal end. The body and the imaging core are cooperatively constructed to enable axial translation of the imaging core and imaging device relative to the body. The body has a transparent distal portion extending an axial length over which axially translatable imaging may be performed. The imaging guidewire has a maximum diameter over its entire length sized to be received within a guidewire lumen of an intravascular catheter.
