Mri/ct-compatible Remote-Controlled Micropositioning System

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a remote-controlled micropositioning system for precisely positioning medical instruments, such as needles or catheters, relative to a patient during MRI or CT-guided minimally invasive procedures. The system comprises an attachment element to secure it to the patient and a mechanism for precise, multi-axis movement of the instrument. It is specifically designed to be compatible with MRI and CT environments through the use of non-metallic materials and remote actuation—using cable-driven mechanisms and optional motors—so that medical staff do not need to operate inside the imaging bore, enabling more accurate and safer interventions.

Use CasesContent extracted from patent full text and abstract with AI.

• Image-guided biopsies in MRI or CT environments, where precision and remote adjustment are critical.
• Minimally invasive targeted drug delivery procedures under MRI or CT guidance.
• Ablation procedures (e.g., radiofrequency ablation) within MRI or CT scanners.
• Placement and adjustment of catheters or interventional devices during real-time imaging.
• Robotically controlled, automated puncture or intervention based on pre-planned trajectories.
• Training systems for interventionists to practice instrument alignment remotely under imaging.

BenefitsContent extracted from patent full text and abstract with AI.

• Highly precise, reproducible positioning of medical instruments, reducing risk of human error.
• MRI and CT compatibility, allowing safe operation within high-field environments using non-metallic, imaging-friendly materials.
• Remote-controlled and potentially automated adjustment, improving ergonomic conditions for medical staff and reducing exposure to strong magnetic fields.
• Increased procedural efficiency and workflow standardization, especially for complex, minimally invasive interventions.
• Compact and lightweight design suitable for use in restricted spaces, such as inside MRI bores.
• Reduces procedure time and enhances patient safety by minimizing the need for repeated manual adjustments and unnecessary punctures.
• Cost-effective, with potential for disposable versions due to simple mechanical construction.
• Improved accuracy in reaching small or deep-seated targets, supporting better diagnostic or therapeutic outcomes.
