Steering Flexible Needles through Soft Tissue

Needles are used in many forms of medical diagnosis and treatment, from tissue biopsies to placement of radioactive seeds for cancer treatment. We are developing a new approach to real-time image-guided adaptive needle placement using new thin, flexible needles that can be steered through deformable tissues around tissue obstacles to reach specified 3D anatomical targets.

Our approach will integrate real-time imaging, adaptive modeling and planning algorithms, and image-guided intraoperative needle control. By enhancing physicians' abilities to accurately maneuver inside the human body with minimal trauma to the patient, our needle steering approach has the potential to improve targeting accuracy for a wide range of procedures, including therapeutic imaging, chemotherapy, cell therapy, biopsy, and tumor ablation. These advances can improve the outcome of existing procedures and enable needle-based procedures for conditions that currently require open surgery or systemic treatment.
