A technique is described herein. The technique includes receiving endpoint location data in a geometry shader; processing the endpoint location data to calculate Bezier curve control points; and based on the Bezier curve control points, determining estimated electrode positions for the catheter.

Tracking coordinates of electrodes

Embodiments of the present invention include a medical probe having a flexible insertion tube, a basket assembly, and a plurality of electrodes. The basket assembly has a proximal end that is connected distally to the insertion tube and includes a plurality of resilient spines, which have respective outer sides and inner sides and are configured to bow radially outward from an axis of the basket assembly and are conjoined at the proximal end and at a distal end of the basket assembly. The plurality of electrodes are fixed to respective ones of the spines in respective longitudinal positions that are staggered on any given spine relative to the longitudinal positions of the electrodes on the spines adjacent to the given spine, and which include a conductive material that is biased towards the respective outer sides of the spines.

An apparatus includes a proximal shaft configured to mechanically couple to a motor, a first universal joint, a middle shaft coupled to the proximal shaft via the first universal joint, a housing having a bore, a second universal joint within the bore, a distal shaft coupled to the middle shaft via the second universal joint, and a connector disposed over the distal shaft. The bore limits a downward tilt of the distal shaft such that, as a rotor approaches the distal shaft, the distal shaft becomes axially aligned with the rotor by virtue of the proximal end of the rotor entering the connector or vice versa. A spring connected proximally to the connector and distally to the second universal joint is configured to decompress, thereby reversibly coupling the connector to the proximal end of the rotor, upon the motor rotationally aligning the connector with the proximal end of the rotor.

The phacoemulsification probe includes a piezoelectric crystal configured to vibrate in response to a drive signal, a needle configured to be inserted into a lens capsule of an eye and to be vibrated by the piezoelectric crystal, and a set of magnetic-field components. The set includes (i) one or more magnetic-field generators configured to generate a magnetic field, and (ii) one or more magnetic-field sensors configured to sense the magnetic field. At least one of the magnetic-field components is coupled to vibrate with the needle and at least one other of the magnetic-field components is isolated from vibration of the needle, thereby causing the magnetic-field sensors to output signals indicative of the vibration. The processor is configured to adaptively adjust a frequency of the drive signal so as to vibrate the needle at a resonant frequency of the piezoelectric crystal.

A method includes, receiving multiple signals from multiple respective electrodes arranged along an inner circumference of a blood vessel that has been ablated. Based on the multiple signals, one or more quality measures of the ablated blood vessel are produced. A graphical presentation indicative of the one or more quality measures, is displayed to a user in a two-dimensional (2D) polar coordinate system.

A power line interference (PLI) suppression method includes receiving an input analog signal superimposed with PLI, and digitally estimating one or more harmonics of the PLI in real-time. Responsively to the one or more digitally estimated harmonics, one or more analog harmonic waveforms are outputted, that match the respective one or more harmonics of the PLI. The input analog signal and the one or more analog harmonic waveforms are received, and the superimposed PLI in the input analog signal is suppressed using the one or more analog harmonic waveforms. An analog output signal is outputted, that corresponds to the input analog signal having the suppressed PLI.

Filtering power line noises from analog electrophysiological signals in real-time

A registration device, including a wand, a light guide passing through the wand, and a position sensor fixed to the wand. A light source outputs a modulated beam of light into a light guide proximal end, so that the light is emitted from a light guide distal end toward a surface in proximity to a wand distal tip. A detector receives, from the light guide proximal end, light reflected from the surface into the light guide distal end, and outputs a signal indicative of the reflected light intensity. A processor computes a distance from the distal tip of the wand to the surface by extracting a phase difference between the output beam and the reflected light from the signal, and computes a position of the surface in a sensor frame of reference responsively to the computed distance and the location of the distal tip found from the position sensor.

The processor is configured to (a) present the one or more user defined eye surgery protocols on the I/O device using the GUI, (b) test compatibility of the one or more user defined eye surgery protocols with the eye surgery system, and (c) provide an indication of the compatibility to a user of the eye surgery system.

The control circuitry is configured to reduce crosstalk between a first RF ablation signal of the plurality of RF ablation current signals and a second RF ablation signal of the plurality of RF ablation current signals by adjusting the respective phase of the first RF ablation signal in relation to the respective phase of the second RF ablation signal such that the respective phase of the first RF ablation signal is different than the respective phase of the second RF ablation signal.

A system for controlling aspiration of a phacoemulsification probe inserted into an eye includes an anti-vacuum surge (AVS) module, one or more sensors, a vacuum relief valve, and a processor. The AVS module is coupled with an aspiration channel of the probe and is configured to mitigate vacuum surges in the channel by regulating flow via the channel.

The vacuum relief valve, which is fluidly coupled with the channel, is configured to controllably relieve vacuum in the channel. The processor is configured to identify a change in at least one of the fluid parameters by reading at least one of the one or more sensors, and, responsively to an identified change in fluid parameters, operate the vacuum relief valve using pulse width modulation (PWM) to maintain a pressure in the channel within a predefined range.

Determined is, that the vacuum level has changed by at least a preset vacuum level change, and in response vibrating the needle is switched to a second trajectory, different from the first trajectory.
