  • Patent number: 10413709
    Abstract: A dilatation catheter includes a high-pressure balloon component comprising an inner balloon and an outer balloon. An interior of the inner balloon is in fluid communication with a lumen of the catheter for receiving inflation fluid therefrom. The outer balloon defines a separate interior within which the inner balloon is disposed. The outer balloon has a hole in a wall thereof for venting the interior of the outer balloon to ambient environment. Proximal necks of the inner and outer balloons are bonded to an outer shaft of the catheter and distal necks of the inner and outer balloons are bonded to an inner shaft of the catheter. In accordance with embodiments hereof, the interior of the outer balloon is not in fluid communication with the interior of the inner balloon, the lumen of the catheter or any other source of fluid from the catheter.

  • Patent number: 10406308
    Abstract: The present invention relates to a catheter for ventilating a patient, with a ventilation channel for alternately delivering and removing air and/or oxygen to and from the patient's airways, the catheter having a maximum external diameter of at most 6 mm, mm, and the ventilation channel having an open end, and a connector end for connection to a gas flow reversing element. According to the invention, the catheter is provided with means or elements for measuring the pressure outside the ventilation channel near the open end. The catheter preferably has a pressure measurement channel, with an open measurement end near the open end of the ventilation channel, and a measurement connector piece for connecting a pressure display device. Of particular advantage is a catheter with an expansion body (cuff) that is fluidically connected to a supply channel through which the expansion body can be increased or reduced in size by means of a fluid.

  • Patent number: 10391281
    Abstract: A delivery sheath includes an outer tubular layer and an initially folded inner tubular layer. When an implant passes therethrough, the outer tubular layer expands and the inner tubular layer unfolds into an expanded lumen diameter. The sheath may also include selectively placed longitudinal support rods that mediate friction between the inner and outer tubular layers to facilitate easy expansion, thereby reducing the push force needed to advance the implant through the sheath's lumen.

  • Patent number: 10376711
    Abstract: Light sources are incorporated into a guidewire for enabling the ability to render light therapy be added to catheters that do not have that capability. In one exemplary embodiment, a solid guidewire includes a conductive core, and light sources are added to compartments formed in a distal end of the guidewire. In another exemplary embodiment, a light source array is included in a distal end of a hollow guidewire. A plurality of openings are formed into the walls of the hollow guidewire surrounding the array, enabling light to pass through the openings. Conductors extend from the array though the hollow center of the guidewire, to a proximal end of the hollow guidewire. The hollow guidewire can be coated with a conductive material, so that the coating on the guidewire serves as a conductor.
