A system comprises a medical instrument, a tracking system configured to monitor a position of the medical instrument, and a processor communicatively coupled to the medical instrument and the tracking system. The processor is configured to generate a plurality of model points of an anatomic structure of a patient, receive a set of measured points of a first portion of the anatomic structure of the patient from the tracking system while the medical instrument is disposed within the anatomic structure of the patient, the set of measured points being associated with a first motion cycle of the medical instrument, map the set of measured points to a first model path of the plurality of model paths, and register the set of measured points with a first portion of the plurality of model points, the first portion associated with the first model path of the plurality of model paths.

Optical coherence tomography scanning probe

An OCT scanning probe includes a tubular housing, at least one electrode, an optical fiber scanner and an auxiliary localization component. The electrode is disposed on an outer surface of the tubular housing. The optical fiber scanner is disposed in the tubular housing and includes an optical fiber and an optical element. The optical element is disposed on an emitting end of the optical fiber and at corresponding position to a light transmittable portion of the tubular housing. The auxiliary localization component is disposed on the tubular housing, and overlaps part of the light transmittable portion. A light beam emitted from the optical fiber scanner passes through the light transmittable portion to obtain a tomographic image. An interaction of the light beam with the auxiliary localization component causes a characteristic in the tomographic image, with the characteristic corresponding to the auxiliary localization component.

Laser-assisted transdermal delivery of nanoparticulates and hydrogels

A method for laser assisted delivery of therapeutic agents includes selectively controlling a valve connected to a first channel disposed within a first sidewall of a nozzle, applying, through the first channel, a first substance to penetrate dermis to a predetermined depth, and administering, through a second channel unconnected with the valve and disposed within a second sidewall of the nozzle, a second substance to remove debris.

Intravascular devices, systems, and methods having a core wire with embedded conductors

Intravascular devices, systems, and methods are disclosed. In some instances, the intravascular device is a guide wire with electrical conductors embedded within a core wire. In some instances, the electrical conductors are coupled to conductive bands adjacent a proximal portion of the guide wire and a sensing element adjacent a distal portion of the guide wire. Methods of making, manufacturing, and/or assembling such intravascular devices and associated systems are also provided.

Method for co-registering and displaying multiple imaging modalities
11324468 · 2022-05-10 · ·

A method for processing angiography image data by using an imaging catheter path that is directly detected from the angiography data as a co-registration path or using detected marker locations from the angiography data to generate a co-registration path. If the acquired angiography data includes synchronized cardiac phase signals and a predetermined quantity of angiography image frames not including contrast media, then a directly detected imaging catheter path is used as the co-registration path. Otherwise the co-registration path is determined based upon detected marker locations from the angiography image data.

INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM

An information processing device that assists understanding of an image acquired by an image acquisition catheter. The information processing device includes: an image acquisition unit that acquires a catheter image including an inner cavity obtained by an image acquisition catheter; a position information acquisition unit that acquires position information regarding a position of a medical instrument inserted into the inner cavity included in the catheter image; and a first data output unit that inputs the acquired catheter image and the acquired position information to a first trained model that, upon receiving input of the catheter image and the position information, outputs first data in which each region of the catheter image is classified into at least three of a biological tissue region, a medical instrument region where the medical instrument exists, and a non-biological tissue region, and outputs the first data.

SYSTEMS, DEVICES, AND METHODS FOR EVALUATING NEUROMODULATION THERAPY VIA DETECTION OF MAGNETIC FIELDS
20220133210 · 2022-05-05 ·

Systems and methods for measuring the magnetic fields generated by renal nerves before and/or after neuromodulation therapy are disclosed herein. One method for measuring the magnetic field of target nerves during a neuromodulation procedure includes positioning a neuromodulation catheter at a target site within a renal blood vessel of a human patient near the target nerves, and detecting a measurement of the magnetic field generated by the target nerves. The method can further include determining, based on the measurement of the magnetic field, a location of the target nerves, a location of ablation at the target nerves, and/or a percentage the target nerves were ablated by delivered neuromodulation energy.

Aspects of the present disclosure relate to systems, devices and methods for performing a surgical step or surgical procedure with visual guidance using an optical head mounted display. Aspects of the present disclosure relate to systems, devices and methods for displaying, placing, fitting, sizing, selecting, aligning, moving a virtual implant on a physical anatomic structure of a patient and, optionally, modifying or changing the displaying, placing, fitting, sizing, selecting, aligning, moving, for example based on kinematic information.

Imaging probe with rotatable core

The present disclosure provides for an imaging probe with a rotatable core which allows for rotating imaging assembly that is larger in diameter than the lumen in which the rotatable core resides, as well as methods to construct said probes. The imaging probes are generally elongate flexible imaging catheters for use in cardiovascular procedures. The ability to have a smaller lumen to hold the rotatable core simplifies the inclusion of other functional components to the catheter and may improve the quality of the images produced.
