  • Patent number: 10265505
    Abstract: A catheter with a mechanism for omni-directional deflection of a catheter shaft includes a shaft assembly and a controller. The shaft assembly includes a first tubular component that has a preformed curvilinear distal section, a second, substantially straight tubular component with a main axis and an outer shaft. The first and second components are configured for slidable movement therebetween while preserving common rotation so that when the second component is axially moved in a distal direction, the second component deflects the preformed curvilinear section towards the main axis while orientation of the outer shaft is preserved. The controller is configured to effect relative axial movement between the first and second components as well as to effect rotation of the first and second components (and thus also of the preformed curvilinear distal section) without any rotation of the shaft relative to the handle.

  • Publication number: 20190038228
    Abstract: Aspects of the present disclosure are directed toward systems and methods for detecting force applied to a distal tip of a medical catheter. In some embodiments, a medical catheter with a deformable body near a distal tip of the catheter deforms in response to a force applied at the distal tip, and a force sensor detects various components of the deformation. Processor circuitry may then, based on the detected components of the deformation, determine a force applied to the distal tip of the catheter.

  • Publication number: 20190022356
    Abstract: Actuators for steerable medical devices are disclosed that not only deflect or steer a portion of a medical device (e.g., a distal portion of a catheter shaft), but also include mechanisms for actively returning the deflected portion of the medical device to an initial configuration (e.g., straight or substantially straight). These active return-to-straight mechanisms may return a catheter shaft from a deflected configuration to a substantially straight configuration throughout a medical procedure, may employ one or more tension members extending along the catheter shaft, and may comprise a gross return actuator and a fine return actuator. For example, the gross return actuator may be configured to partially reverse the deflection of the distal portion of the catheter; and the fine return actuator may be configured to continue reversing the deflection. The gross return actuator may automatically trigger or actuate (mechanically or electromechanically) the fine return actuator.

  • Publication number: 20180353203
    Abstract: An ablation device includes an elongate catheter body having a lumen extending therethrough and a distal region. An ablation element, such as one or more ultrasound transducers, is disposed within the distal region such that it can emit ablative energy outwardly relative to the longitudinal axis of the catheter body. A balloon is positioned about the distal region of the catheter body, typically with the ablation element positioned within the balloon. The balloon is expandable outwardly from an outer surface of the catheter body such that, when the balloon is inflated, an exterior surface of the balloon stably engages an interior wall of a blood vessel without occluding blood flow therethrough. For example, the balloon can be cross-shaped when inflated. To create circumferential lesions without repositioning the catheter, the ablation element can rotate about and/or slide along the longitudinal axis of the catheter body.

  • Patent number: 10076637
    Abstract: Deflection actuators configured to provide variable mechanical advantage and to optionally maintain a desired state of deflection are disclosed. Each deflection actuator may comprise a plurality of planar components, at least one of which is adapted to move relative to at least one other component. The planar components may comprise a channeled platform and a pivotable base mounted adjacent to the channeled platform. The platform may comprise a slider trough to slidably retain a slider. The base may have a cam arm pivotally connected to it and adapted to push a slider in its trough, whereby pivoting of the pivotable base relative to the channeled platform produces linear motion by the slider in its slider trough. The deflection actuator may also comprise a friction-lock knob, a knob receiver, and a pivot hub to selectably produce friction between various components to hold a catheter shaft in a desired state of deflection.
