    Abstract: A deflectable catheter shaft section is disclosed comprising an elongated body extending along a longitudinal axis with a distal end and a proximal end. First and second pull wires can extend along the elongated body and can have a proximal end and a distal end. First and second pull wire liners can be disposed over a portion of one of the first and second pull wires, respectively. Each of the first and second pull wires can have a proximal end and a distal end. A first gap can exist between the proximal end of the first pull wire liner and the proximal end of the elongated body and a second gap can exist between the proximal end of the second pull wire liner and the proximal end of the elongated body.

    Abstract: Embodiments include a catheter shaft (12) having an elongated structure with a distal portion (18) and proximal portion (16). The distal portion (18) can include a distal tip (36), a proximal connector (38), and a plurality of pivoting hollow cylindrical segments (40) disposed between the proximal connector (38) and distal tip (36) along a longitudinal axis extending through the elongated structure. A plurality of connections (42, 44) can be disposed along diametrically opposed sides of the distal portion (18) and configured to connect the distal tip (36), the pivoting hollow cylindrical segments (40), and the proximal connector (38). A diametrically opposed pair of tabs (54-1, 54-2) can extend from an inner wall of each of the pivoting hollow cylindrical segments (40) to form first and second pullwire tunnels (81-1, 81-2). First and second pullwires (52-1, 52-2) can extend through the first and second pullwire tunnels (81-1, 81-2).

    IPC: A61M25/01

    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.

    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.

    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. Varying the deflection of the preformed curvilinear section in combination with variable rotational movement achieves omni-directional distal tip bending.

A catheter includes an elongate catheter shaft comprising a proximal end and a distal end. The elongate catheter shaft defines a longitudinal axis. The catheter includes an expandable assembly having a first delivery configuration and a second deployed configuration. The balloon member includes at least one flexible framework disposed between an outer facing layer and an inner facing layer of the top surface and/or the bottom surface of the balloon member and at least one plurality of electrodes patterned onto the flexible framework. In some embodiments, a flat balloon member includes electrodes on both sides of the planar balloon member. The balloon member may include a flexible structural element disposed within the interior cavity.
