Publication number: 20220061871Abstract: In some examples, a catheter includes an expandable member configured to expand radially outward from a collapsed configuration to an expanded configuration. The expandable member is configured to be expanded and contracted in a controlled manner, e.g., in response to user actuation or automatically under the control of control circuitry of a device. For example, in some examples, control circuitry of a device can be configured to control the expandable member to expand and contract according to a predetermined expansion frequency or according to an expansion frequency determined based on a cardiac cycle of a patient.Type: ApplicationFiled: August 31, 2020Publication date: March 3, 2022Inventor: Eric Mintz

Publication number: 20210308431Abstract: In some examples, a catheter includes one or more balloons that, when inflated, are configured to be apposition with vasculature or other hollow anatomical structure of a patient to help anchor the catheter within the vasculature, while still permitting fluid to flow past the inflated balloons. When inflated, the one or more balloons define one or more passageways configured to enable fluid to flow past the inflated balloons in a direction along a longitudinal axis of the catheter. For example, the catheter may comprise a plurality of balloons that are circumferentially and longitudinally staggered relative to each other.Type: ApplicationFiled: April 3, 2020Publication date: October 7, 2021Inventors: Ujwal Jalgaonkar, Gaurav Girdhar, Eric Mintz, Alejandra Turcios, Syamala Rani Pulugurtha

Patent number: 10946167Abstract: A hub defines a lumen with a longitudinal axis along the length of the hub. An outer surface of a distal portion of the hub tapers inwardly toward the longitudinal axis as the distal portion extends distally. A strain relief includes a proximal portion configured to receive the distal portion of the hub. The strain relief defines a lumen that substantially aligns with the hub lumen when the proximal portion receives the hub. The hub and/or strain relief are configured to be fixedly attached to a catheter body such that a catheter body lumen substantially aligns with the hub lumen and the strain relief lumen when the strain relief receives the distal portion of the hub. Outer surfaces of the strain relief and hub define substantially similar distances to the longitudinal axis along an interface between the two outer surfaces when the strain relief receives the hub.Type: GrantFiled: June 14, 2018Date of Patent: March 16, 2021Assignee: Covidien LPInventors: Eric Mintz, David P.
