  • Patent number: 9844353
    Abstract: For position sensors, e.g., a fiber-based system, that build a shape of an elongated member, such as a catheter, using a sequence of small orientation measurements, a small error in orientation at the proximal end of the sensor will cause large error in position at distal points on the fiber. Exemplary methods and systems are disclosed, which may provide full or partial registration along the length of the sensor to reduce the influence of the measurement error. Additional examples are directed to applying selective filtering at a proximal end of the elongated member to provide a more stable base for distal measurements and thereby reducing the influence of measurement errors.

  • Patent number: 9005217
    Abstract: Apparatus for controlling a steerable invasive probe having a handle. The apparatus includes a platform and a jig, which is mounted on the platform and is configured to receive the handle. The jig includes at least a first gear that is positioned and shaped to rotate the handle about an axis of the probe and a second gear that is positioned and shaped to operate a control on the handle for deflecting a tip of the probe. A drive module includes one or more motors. A transmission is coupled to the drive module and to the jig so as to controllably rotate at least the first and second gears and to translate the platform along a direction parallel to the axis in order to advance and retract the probe.

  • Publication number: 20150073339
    Abstract: Various embodiments enable an introducer for a catheter to be rotated around an axis and/or traversed backward and/or forward along the axis. In various embodiments, positioning of an introducer may be enabled by an introducer support configured to be rotated around an axis and/or extended or retracted along the axis. The introducer may be manually operated and/or operated by motors in a nose cone of a catheter positioning system. In various embodiments, a portion of the introducer support may be configured to flex. In other embodiment, positioning of an introducer may be enabled by an adjustable nose cone of a catheter positioning system.

  • Patent number: 8974453
    Abstract: An irrigated ablation catheter includes a shaft having a proximal end, a distal end, and an irrigation lumen therein. The catheter further includes an electrode assembly coupled to the distal end of the shaft. The electrode assembly includes an ablation electrode and a manifold. The manifold is coupled to each of the distal end of the shaft and the proximal end of the electrode. At least a portion of the manifold is constructed of a flexible material to allow the electrode assembly to deflect. The manifold includes a body, an inner cavity within the body configured for fluid communication with the irrigation lumen, and an irrigation port also within the body and configured for fluid communication with the inner cavity. The irrigation port extends from the inner cavity to the outer surface of the body, and is configured to allow for an irrigating fluid to be distributed from the manifold.

  • Publication number: 20150065952
    Abstract: Various embodiments provide a catheter positioning device with components for controlling actuators of the catheter in multiple axes. A catheter may be attached to a sled member by a modular plate with one or more actuator interfaces that may couple with the actuators of a catheter handle. One or more motors or drives in the sled member may move the actuator interfaces of the modular plate to control one or more actuators on the catheter in different axes. In various embodiments the sled member may have a clam shell design in which two or more sides of the sled member close around the catheter handle. In further embodiments, the sled member may include adjustable faces that can fit different types of modular plates and thereby control actuators on different types of the catheter.

  • Publication number: 20150051584
    Abstract: A catheter insertion device that allows for single-handed insertion of the catheter within the vasculature of the patient is disclosed. The catheter insertion device includes a handle, a needle cannula partially within the handle, a guidewire partially within the handle and the needle cannula, and a first actuator connected to the handle and the guidewire. The first actuator is movable in a proximal direction relative to the handle to cause the guidewire to move in a distal direction away from the handle, and is movable in a distal direction relative to the handle to cause the guidewire to move in a proximal direction towards the handle. The catheter insertion device can also include a needle support that stabilizes the needle cannula during insertion of the needle cannula into a patient.

  • Patent number: 8951224
    Abstract: An interventional catheter assembly has an operating head and catheter system that are inserted and navigated within a patient's body while an operator controls the system externally of the operating head. An operating head is positioned at or near a distal end of the catheter system and coupled to a drive shaft and drive system for rotation. A guidewire brake control system interrupt prevents the drive system from being actuated when the guidewire brake is in a released position, and a selectable guidewire brake interrupt override control permits an operator to translate and/or rotate the drive shaft and operating head while the guidewire is simultaneously moved. This allows withdrawal of the guide wire and the operating head from the target site while rotating the operating head.

  • Patent number: 8926588
    Abstract: A steerable delivery catheter includes an outer sheath with a housing disposed at a distal end thereof to define a chamber for a medical device, the chamber having an open distal end and a proximal inner shelf. An inner shaft is slidably disposed within the sheath and has an abutment attached to the distal end of the shaft, the abutment being slidably contained within the chamber. During navigation of the catheter, when the inner shaft is tensioned the abutment engages the shelf to apply a compressive force to the sheath to selectively deflect a distal region of the catheter. When the catheter has been navigated to the deployment site the sheath is withdrawn while the abutment maintains the medical device in place as it is deployed. A delivery method also is disclosed.

    Abstract: A method for monitoring the seating of a guide catheter during a catheter procedure includes monitoring at least one parameter of the catheter procedure and determining if the at least one parameter indicates that a guide catheter is out of position. If the at least one parameter indicates the guide catheter is out of position, an alert is displayed and the position of the guide catheter is adjusted. The parameter may be, for example, blood pressure, an ST wave of an electrocardiogram, contrast agent, fluoroscopic images of a region including the distal end of the guide catheter and ultrasound signals.
