Abstract: Systems and processes for facilitating the removal of cataract material with a robotically assisted tool with laser, irrigation capabilities, aspiration capabilities. Tool guidance systems that make use of vision technologies, including optical coherence tomography (OCT), white light imaging, and structured light imaging. Emulsification patterns optimized to minimize risk to the patient and reduce procedure time. Robotic tools with articulation capabilities that allow for precise control during capsulorhexis and emulsification procedures. Robotic instrument drive mechanisms combined with pumps, flow meters, and valves regulate and control irrigation and aspiration functionalities during robotic ophthalmologic procedures.

Abstract: An input device includes a plurality of orientation blocks each representing a portion of a catheter assembly and a controller configured to determine an orientation of the plurality of orientation blocks relative to one another. The controller is further configured to output a control signal that causes a tip of a catheter assembly to adopt the orientation determined by the controller. A system includes an actuator configured to manipulate a position and orientation of the catheter assembly. The controller of the input device is configured to output a control signal to the actuator to make a tip of a catheter assembly adopt the orientation determined by the controller. The input device can be virtually represented on a computing device.

Abstract: An input device for a robotic catheter system includes an inner member having a generally cylindrical shape and defining an axis, and an outer member coaxially disposed on the inner member and configured to rotate about and move along the axis defined by the inner member to control a position and orientation of at least one of a catheter and a guide wire. Rotating the outer member about the axis causes the catheter, the guide wire, or both, to rotate and wherein moving the outer member along the axis causes the catheter, the guide wire, or both, to advance or retract relative to a patient's body.

Abstract: A device may operate a guide wire and be operable by a single operator digit. The device may include an insertion control device for advancing the guide wire in a forward and in a reverse direction and along a longitudinal axis of the guide wire; and a rotary device for rolling a guide wire about the longitudinal axis. A robotic instrument driver may be operatively coupled to the device and configured to control axial movement of the guide wire along the longitudinal axis according to input received from the insertion control device and to control rotational movement of the guide wire according to input received from the rotary device.

Abstract: Intralumenal devices and methods are provided for transmucosal drug delivery. The device may comprise a housing configured for intralumenal deployment into a human or animal subject; a drug-dispensing portion which contains at least one drug; and an electrically-actuatable portion configured to disrupt at least one region of a mucosal barrier adjacent to the housing at a selected time while intralumenally deployed in the human or animal subject. The device may be operable to dispense the drug from the housing to a region of the mucosal barrier disrupted by the electrically-actuatable portion.

Abstract: A dual-mode, capable of imaging and ablation, ultrasound array integrated in a catheter is provided for minimally invasive treatment of arrhythmias. The catheter array is small enough for insertion through a peripheral vein and is longitudinally integrated with the catheter to have a side-view for tissue imaging and ablation. A high length/width array ratio creates a large aperture necessary for high power ablation densities. A catheter stabilization device maintains a distance between the catheter array and the wall of a heart or vein. Visualization of anatomy and imaging of ablated tissue provides a guide for placing the lesion and assists in achieving a pattern of ablated tissue. The catheter is advanced to another area by catheter rotation and/or array steering or focusing. Gating the imaging and ablation processes to a heart cycle allows for accounting and compensation of heart motion and enables automation of an arrhythmia treatment.
