  • Publication number: 20200008820
    Abstract: A catheter is provided which includes an outer catheter and an extendable inner catheter. A sealing feature is positioned between the inner catheter and the outer catheter to seal the annular gap between the two while allowing axial translation. The seal may be a compliant protrusion surrounding the inner catheter and may have a chevron-shape for facilitating axial translation. The seal may be a one-way valve configured to allow antegrade flushing but prevent retrograde flow. The seal may be squeegee-like flange on the distal tip of the outer catheter. The seal may be an expandable bulge, which may be mechanically expandable or inflatable or which may be a photosensitive or electrosensitive hydrogel. The seal may include a spring that is radially compressed upon translation or rotation of the inner catheter to transiently break the seal. Also provided is a seal for sealing between the catheter and the vasculature.

  • Publication number: 20200001046
    Abstract: A neurovascular catheter having an angled distal tip has an elongate flexible tubular body with a proximal end, a distal end and a side wall defining a central lumen. The side wall has a helical coil. A tubular jacket surrounds the helical coil, and extending distally beyond the helical coil distal end to terminate in a catheter distal face. A tubular radiopaque marker is embedded in the tubular jacket in between the distal end of the coil and the distal face. The distal face resides on a plane which crosses a longitudinal axis of the tubular body at an angle within the range of from about 35 degrees to about 55 degrees. The marker has a proximal face that is approximately perpendicular to the longitudinal axis and a distal face that resides on a plane which crosses the longitudinal axis at an angle within the range of from about 35 degrees to about 55 degrees.

  • Patent number: 6682501
    Abstract: A cell necrosis apparatus includes an elongated member with a longitudinal axis. The elongated member being is configured to be positionable and maneuverable in an oral cavity. First and second energy delivery devices are positioned at a distal portion of the elongated member. Each of the first and second energy delivery devices is laterally offset from the longitudinal axis. In another embodiment, the apparatus can also include a template with a tissue penetrating introducer and a lumen. The energy delivery device is configured to be advancable from the first lumen into a tonsil intratonsil lymphoid stroma.
