Generating approximations of cardiograms from different source configurations
11576624 · 2023-02-14 · ·

Systems are provided for generating data representing electromagnetic states of a heart for medical, scientific, research, and/or engineering purposes. The systems generate the data based on source configurations such as dimensions of, and scar or fibrosis or pro-arrhythmic substrate location within, a heart and a computational model of the electromagnetic output of the heart. The systems may dynamically generate the source configurations to provide representative source configurations that may be found in a population. For each source configuration of the electromagnetic source, the systems run a simulation of the functioning of the heart to generate modeled electromagnetic output (e.g., an electromagnetic mesh for each simulation step with a voltage at each point of the electromagnetic mesh) for that source configuration. The systems may generate a cardiogram for each source configuration from the modeled electromagnetic output of that source configuration for use in predicting the source location of an arrhythmia.

Light and shadow guided needle positioning system and method

The embodiments of the present invention provide a system and method for light and shadow guided needle positioning. DICOM images of a patient are captured for identifying a point of insertion of a needle on the patient's body and a target point inside the patient's body. Needle coordinates are computed based on the captured DICOM images to position the mechanical arms. Light is projected at a particular angle on the needle to form shadows of the needle. Laser light beams are projected to form cross hair at the point of insertion. Images or videos of the point of insertion, shadow of the needle and the cross hair are captured and displayed on a monitoring unit. A virtual circle is projected on the displayed image and is aligned with the point of insertion, shadow of the needle and cross hair in order to insert the needle precisely.

Systems and methods for 3D stereoscopic angiovision, angionavigation and angiotherapeutics
11577049 · 2023-02-14 · ·

Devices, systems, and methods for catheterization through angionavigation, cardionavigation, or brain navigation to diagnose or treat diseased areas through direct imaging using tracking, such as radiofrequency, infrared, or ultrasound tracking, of the catheter through the patient's vascular anatomy. A steerable catheter with six degrees of freedom having at least a camera and fiber optic bundle, and one or more active or passive electromagnetic tracking sensors located on the catheter is guided through the vascular system under direct imaging. The direct imaging can be assisted with at least one of MRA imaging, CT angiography imaging, or 3DRA imaging as the roadmap acquired prior to or during 3D stereoangiovision. The system comprises RF transceivers to provide positioning information from the sensors, a processor executing navigation software to fuse the tracking information from the tracking sensors with the imaging roadmap, and a display to display the location of the catheter on the roadmap.

Cranial surgery using optical shape sensing

Various cranial surgery OSS registration device embodiments of the present disclosure encompass a cranial surgery facial mask (128), a mask optical shape sensor (126b) having a mask registration shape extending internally within the cranial surgery facial mask (128) and/or externally traversing the cranial surgery facial mask (128), a cranial surgery tool (101), and a tool optical shape sensor (126d) having a tool registration shape extending internally within the cranial surgery tool (101) and/or externally traversing the cranial surgery tool (101). The mask registration shape of the mask optical shape sensor (126b) and the tool registration shape of the tool optical shape sensor (126d) interactively define a spatial registration of the cranial surgery facial mask (128) and the cranial surgery facial mask (128) and the cranial surgery tool (101) to a cranial image.

ENHANCED PLANNING AND VISUALIZATION WITH CURVED INSTRUMENT PATHWAY AND ITS CURVED INSTRUMENT

Exemplary methods and systems that provide a curved path trajectory that can be used with a bendable medical device. The curved pathway can comprise straight and curved concatenated arc segments. The methods and systems can provide planning, visualizing and treatment of, for example, temporal lobe epilepsy (TLE) using laser interstitial thermal therapy (LITT) or tumors using ablation therapy. With curved pathway, the physician can create plan for intervention to avoid critical structure and to cover more target volume for treatment/diagnosis than straight pathway

A surgical device comprising an elongated body, a tissue penetrating apparatus and a light projector. The elongated body can reach with distal end thereof a surface of an organ within a subject's body. The tissue penetrating apparatus can be extended from the elongated body distal end along a curved penetration path restricted to a chosen penetration plane. The light projector can generate a shaped illumination on the surface of the organ indicative of an intersection of the penetration plane with the surface of the organ.
