SYSTEM AND METHOD FOR PLACEMENT OF NEUROSTIMULATION LEADS USING AUGMENTED REALITY

Smart overview of the Invention

The patent application describes a system and method for guiding the placement of neurostimulation leads using augmented reality (AR). The system integrates an X-ray imaging system to capture patient images, which are then processed and displayed through an AR interface. This approach aids in the accurate insertion of needles to place leads for a peripheral nerve evaluation (PNE) procedure, specifically targeting the sacral S3 spinal nerve associated with sacral neuromodulation therapy.

Background

Sacral neuromodulation is a treatment for bladder and bowel dysfunction, involving the implantation of a device that stimulates the sacral S3 spinal nerve. Before a permanent implant, patients undergo a PNE procedure with temporary leads to evaluate the therapy's effectiveness. Traditional lead placement methods rely on identifying skeletal landmarks, often leading to inaccuracies due to anatomical variations. This can result in multiple failed attempts, improper lead placement, and possibly the abandonment of the treatment.

Innovative Approach

The disclosed system enhances the accuracy and efficiency of locating sacral foramina for lead placement. It involves capturing images of the patient and processing them to identify key anatomical points. These measurements are then transferred to a head-mounted display (HMD), which projects them onto the display, providing real-time visual guidance. This method surpasses conventional techniques by offering precise guidance, reducing the likelihood of errors in lead placement during the PNE procedure.

System Components

The system includes a combination of imaging technologies, such as X-ray or fluoroscopy, to capture detailed anatomical images. The processed images are displayed on electronic devices like smartphones, computers, or HMDs, which can also superimpose measurements onto live video feeds. This setup allows physicians to accurately locate the S3 foramen, improving the success rate of needle insertion and lead placement.

Implementation and Benefits

The method involves obtaining a scaled image of the patient, identifying key anatomical landmarks, and calculating precise measurements for needle insertion. These measurements are then displayed on an HMD, overlaying indicators on the patient to guide the procedure. By utilizing cloud-based computing for calculations, the system ensures accurate and efficient lead placement, ultimately enhancing the clinical outcomes of sacral neuromodulation therapy.
