  • Introducer sheaths, thrombus collection devices, and associated methods
    Patent number: 11266434
    Abstract: A sheath comprises an elastomeric tube having a self-expanding scaffold coupled to a wall. The scaffold can expand to a diameter larger than the tube diameter to provide an enlarged distal opening. An aspiration catheter has a balloon and an aspiration port so that occlusive material can be removed from a blood vessel by drawing the balloon through the vessel while simultaneously aspirating through the port.
    Type: Grant

  • Methods and apparatus for introducing tumescent fluid to body tissue
    Patent number: 9055956
    Abstract: A catheter is usable to treat a hollow anatomical structure (HAS). The catheter comprises one or more shafts which extend away from a proximal end of the catheter toward a distal end thereof. The catheter further comprises an HAS constriction energy source located at or near the distal end of the catheter. The catheter further comprises at least one radially expandable transmural fluid delivery channel located in the catheter near the HAS constriction energy source.

  • Systems and methods for treating a hollow anatomical structure
    Patent number: 7842076
    Abstract: A treatment system for occluding a hollow anatomical structure comprises a treatment device sized for insertion into a hollow anatomical structure. The treatment device comprises a therapeutic element configured to treat the hollow anatomical structure. The system comprises a sensor configured to sense a first treatment parameter. A controller is in communication with the treatment device and with the sensor. The controller is configured to determine a second treatment parameter based on the first treatment parameter and output the second treatment parameter.
