Marker and medical device for visualizing instruments and devices during MRI imaging, and method for manufacturing the same

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

This invention describes a marker and a medical device for highlighting the location and orientation of instruments during MRI (Magnetic Resonance Imaging) procedures. The marker, made from at least one type of plastic, features at least one hollow space within its body that is partially filled with a liquid plastic. This special configuration makes the marker highly visible on MRI scans, enabling accurate localization and alignment of medical instruments, and it is produced using additive manufacturing (e.g., 3D printing).

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

• Guiding and visualizing biopsy or surgical instruments during MRI-guided interventions.
• Manufacturing customizable, patient- or procedure-specific MRI markers for interventional radiology or surgery.
• Providing improved reference markers in MRI for positioning and tracking non-metallic medical devices.
• Developing MR-compatible medical devices that require precise localization without causing imaging artifacts.
• Utilizing the marker in training or simulation environments to enhance MRI-based navigation skills for clinicians.

BenefitsContent extracted from patent full text and abstract with AI.

• Highly visible under MRI imaging, improving the accuracy and safety of MRI-guided interventions.
• Does not use metals, eliminating risks of patient injury or imaging artifacts from metallic components.
• Customizable shape and internal structure, tailor-made for specific clinical requirements by additive manufacturing.
• MR-compatible materials ensure there is no magnetic attraction or interference with imaging quality.
• Allows precise instrument orientation and trajectory control, reducing procedural errors.
• Cost-effective and flexible production using modern manufacturing techniques such as 3D printing.
