  • Patent number: 12588925
    Abstract: A thrombectomy device includes a coring member configured to disintegrate a thrombus in a vessel into fragments from a proximal side of the thrombus and a catch member configured to be anchored at a distal side of the thrombus to provide embolic protection. The coring member and the catch member are operable independently of each other. Methods of removing a thrombus from a vessel employ a rotating coring device to disintegrate the thrombus into fragments.
    Type: Grant

  • Patent number: 9808266
    Abstract: The apparatus includes a catheter having a combined infusion/aspiration lumen, a three lumen proximal portion and a two lumen distal portion. An infusion/aspiration valve located at the distal end of the catheter facilitates performing infusion and aspiration through the same lumen, which in turn reduces the number of lumens, and enables the combined infusion/aspiration lumen to be made larger without the need to increase the diameter of the catheter. Differing material properties in the proximal and distal portions of the catheter enable the proximal portion to be made stiffer for pushability, while the distal portion is more flexible to navigate tortuous vasculature and enable a greater amplitude agitator to be received within the catheter.

  • Patent number: 9242068
    Abstract: An infusion catheter includes a catheter body having a proximal end, a distal end, and two or more lumens extending therethrough. The infusion catheter also includes an infusion tube having a proximal end, a distal end, and one or more ports disposed therethrough. The first lumen of the catheter body is in fluid communication with the lumen of the infusion tube. A central member has a distal end connected to the distal end of the infusion tube, a proximal end, and a proximal portion slidably received in the second lumen of the catheter body. The infusion tube is disposed relative to the central member such that axial advancement of the central member relative to the catheter body radially collapses the infusion tube over the central member and axial retraction of the central member relative to the catheter body radially expands the infusion tube about the central member.

  • Publication number: 20100295870
    Abstract: This invention related to a clinical connectivity device coupled to a display. The clinical connectivity device comprises a user interface configured to select a display format; a controller configured to receive commands from the user interface and for controlling operation of the clinical connectivity device; and a selector coupled to the controller and an adjuster. The selector is configured to receive input signals of graphics, image, video, audio or data from devices in a clinical setting and is further configured to select a signal to be transmitted to an adjuster based on the input signal format. The adjuster is coupled to the controller and the display for matching the received signal format to the display format.
