  • Publication number: 20200330111
    Abstract: A reentry catheter for crossing a vascular occlusion includes an elongate flexible tubular body, having a proximal end, a distal end and at least one lumen extending there through. A reentry zone on the tubular body includes at least two and preferably three sets of opposing pairs of axially spaced exit apertures in communication with the lumen. The apertures are rotationally offset from each other and aligned in a spiral pattern around the tubular body. Each aperture may be defined within a radiopaque reinforcing ring embedded within the tubular body. A first set of opposing pairs of reinforcing rings may be separated axially from a second set of opposing pairs of reinforcing rings and may be connected by a flexible hinge section.

  • Publication number: 20200330731
    Abstract: Intravascular catheters with fluoroscopically visible indicium of rotational orientation are described. The catheter includes an elongate flexible tubular body, having a proximal end, a distal end and a tubular side wall defining at least one lumen extending there through. At least first and second opposing pairs of radiopaque rings are embedded in the side wall, spaced axially apart from each other. A first transverse axis extending through the first pair of rings is rotationally offset from a second transverse axis extending through the second pair of rings. The rings may be supported by a subassembly integrated into the wall of the catheter. The subassembly may include a tubular body having a plurality of aperture portions connected by intervening hinge portions. In one implementation, the catheter is a reentry catheter.

  • Publication number: 20200315639
    Abstract: A reentry catheter for crossing a vascular occlusion includes an elongate flexible tubular body, having a proximal end, a distal end and at least one lumen extending there through. A reentry zone on the tubular body includes at least two and preferably three sets of opposing pairs of axially spaced exit apertures in communication with the lumen. The apertures are rotationally offset from each other and aligned in a spiral pattern around the tubular body. A method of crossing a chronic total occlusion includes the steps of advancing the reentry catheter across the occlusion via a channel formed in the subintimal space, and advancing a guidewire via a selected exit port into the native lumen distally of the occlusion. The catheter may be removed, leaving the guidewire across the occlusion to guide further interventional devices.

  • Publication number: 20080143834
    Abstract: A system for evaluating and monitoring driver proficiency, performance and safety is disclosed. The system includes an apparatus having a controller that is in operative association with one or more video cameras mounted within a vehicle for providing audio/video data to the controller as well as with an OBD connection for the collection and transmission of vehicle data from the vehicle to the controller. The controller further includes a microprocessor for synchronizing the recorded vehicle data from the vehicle with the video/audio data collected from the video cameras in order to evaluate and monitor a driver's performance and proficiency.
