  • Publication number: 20180078685
    Abstract: A catheter device and method for treating an artery with thrombus, the catheter comprising an inflatable member. A carrier catheter has a proximal end and a distal end adapted to be inserted percutaneously into an artery, the carrier catheter having a tubular body adjacent to a rear end of the inflatable member. An inflating tube passes through the tubular body and having an open front end in fluid communication with the inflatable member to inflate same. An infusion tube is adapted to infuse pharmacologic agents, the infusion tube passing through the tubular body and having an open front end extending beyond the inflatable member. An aspiration tube is adapted to aspire the thrombus, the aspiration tube passing through the tubular body and having an open front end between the carrier catheter and the inflatable member.

  • Publication number: 20180064482
    Abstract: The present invention provides a medical device that may include a catheter body having proximal and distal portions, a fluid injection lumen disposed within elongate body, and a guidewire lumen disposed within the elongate body. A tip portion defining a cavity in fluid communication with the fluid injection lumen may be coupled to the distal end of the guidewire lumen, and an expandable element may be coupled to the distal portion of the catheter body and to the tip portion, such that the expandable element is in fluid communication with the fluid injection lumen. A shaping element may at least partially surround the expandable element, where the shaping element is configurable in a first geometric configuration and a second geometric configuration.

  • Publication number: 20180036057
    Abstract: A system and method for controlling the inflation, ablation, and deflation of a balloon catheter. The system includes a balloon catheter, a console, a pressurized gas or liquid inflation source, and an umbilical system to deliver pressurized coolant to the balloon catheter. The system may include controller that monitors the amount of pressure and volume within the balloon catheter. During inflation, the pressure and/or volume of fluid within the balloon is maintained at a target amount in order to provide sufficient mechanized pressure against the desired target region. The system limits the inflation pressure such that a safe quantity of gas would be released should a leak occur. If the amount falls below a certain threshold level, gas or fluid egress is presumed and the inflation process is halted.
