Publication number: 20240115277Abstract: 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: December 15, 2023Publication date: April 11, 2024Inventors: Eric Mintz, Ujwal Jalgaonkar, Emma Hurst, David P.

Patent number: 11819627Abstract: 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: October 28, 2020Date of Patent: November 21, 2023Assignee: Covidien LPInventors: Eric Mintz, David P.

Publication number: 20230277187Abstract: Expandable devices for occluding bifurcation aneurysms are disclosed herein. Several of the embodiments are directed towards an expandable device comprising a mesh configured to be deployed at a treatment site including blood vessel bifurcation of a human patient so that the mesh extends across a neck of an aneurysm and prevents or limits blood flow through the mesh and into the aneurysm. The mesh can comprise one or more circumferentially discontinuous portions so that, when the device is deployed at the treatment site, the device does not substantially impede flow from a parent blood vessel to two or more branching blood vessels. Systems and methods for delivering an expandable device of the present technology are also disclosed herein.Type: ApplicationFiled: March 2, 2022Publication date: September 7, 2023Inventors: Mark Philip Ashby, Ashok Nageswaran, Eric Mintz, Gaurav Girdhar, Ujwal Ramesh Jalgaonkar, John Wainwright
